  I am just about to look into integrating this jar into my Mono for Android project as well, so any support Xamarin can muster to resolve these issues would be much appreciated! Did you get any followup offline, Shawn?

  I submitted a separate email to you guys explaining a possible bug in the mono for android build scripts where more than 1 reference jar caused the same android identifier to be used for all of them causing a duplicate error message.

  This was filed as bug #9696, which will be fixed in the forthcoming 4.6 release, and you can fix the issue locally by making a one-line change to Xamarin.Android.Bindings.targets.

  It looks like the ESRI ArcGIS jar is obfuscated such that the Dalvik VM cannot understand it when run from mono for android.

  I find that doubtful, but we can dig deeper. As per the logcat, the problem is:

  01-19 02:39:56.719: W/dalvikvm(1507): Unable to resolve superclass of Lcom/esri/core/geometry/MultiPath; (709)
  

  What is the superclass of com.esri.core.geometry.MultiPath?

  $ javap -classpath Jars/ArcGIS_Android.jar com.esri.core.geometry.MultiPath | head -1
  public abstract class com.esri.core.geometry.MultiPath extends com.esri.core.geometry.x implements java.io.Serializable{
  

  So Dalvik can't find com.esri.core.geometry.x. This is where we can begin investigation: has that type been compiled into the .apk?

  # Build your project, then...
  $ cd $PROJECT_DIR/bin/Debug
  $ mkdir t
  $ cd t
  $ unzip ../*-Signed.apk
  
  # contents may vary
  $ ls
  AndroidManifest.xml META-INF            classes.dex         lib                 res                 resources.arsc
  
  $ dexdump classes.dex
  Class #0            -
    Class descriptor  : 'Lmono/android/IGCUserPeer;'
    Access flags      : 0x0601 (PUBLIC INTERFACE ABSTRACT)

    Interfaces        -
    Static fields     -
    Instance fields   -

        name          : 'monodroidAddReference'
        type          : '(Ljava/lang/Object;)V'
        access        : 0x0401 (PUBLIC ABSTRACT)
        code          : (none)
      #1              : (in Lmono/android/IGCUserPeer;)
        name          : 'monodroidClearReferences'
        type          : '()V'
        access        : 0x0401 (PUBLIC ABSTRACT)
        code          : (none)
    source_file_idx   : 164 (IGCUserPeer.java)
  ...    
  

  dexdump is an Android SDK tool; it disassembles a .dex file, which is the Dalvik bytecode that is actually executed on the device (sans the parts that are executed by mono). Output contains every type, field, contained within the .apk.

  Redirect the output to a file (or less, etc.). What you want to see is if the com.esri.core.geometry.x is present. Type names are in JNI format (as seen above), so you'll want to look for:

    Class descriptor  : 'Lcom/esri/core/geometry/x;'
  

  If the type doesn't exist, there's something wrong with your compilation; double check everything to make sure that ArcGIS_Android.jar is being fully included into your application.

  I wonder if my solution to issue #2 above where I unzipped the ArcGIS jar and rezipped joining in other jars is the cause of this problem?

  How did you unzip and rezip them? On what operating system? .zip file entries can be case-sensitive, particularly when dealing with obfuscated code:

  $ jar tf Jars/ArcGIS_Android.jar  | grep -i '\<X\>'
  com/esri/core/internal/a/a/x.class
  com/esri/core/geometry/x.class
  com/esri/core/geometry/X.class
  

  and...boom, there we go, two entries which differ only in case, and one of them happens to be the class we're interested in.

  I suspect you extracted your .jar on Windows or OS X (both of which default to case-insensitive filesystems), so your final .jar probably only contains one of those types, not both, which would explain everything else.

  Jonathan, that is one awesome answer to my question! Very good information contained within. Yes, you are exactly correct, my combined jar did not contain all case versions of all class files. Two things worth mentioned here for others:

  1. I applied the patch for bug 9696 and it solved both of my problems. I no longer had to use my bad combined jar to workaround the bug and could put the 3 separate reference jars in the binding project. Those carried over to the app project and onto the simulator and the app ran great with an ESRI map view inside.

  2. Before hearing about the patch for bug 9696, I was able to workaround my bad combined jar issue. Not knowing it was a bad combined jar at the time, I still used it in my binding project to satisfy any build references, but I did NOT want it to carry over (or embed) into the app for runtime on the simulator. I discovered that if I set my bad combined jar to buildaction = ReferenceJar, that it uses it only to satisfy build references but does NOT embed it in the final app. But, of course, I need those jars files embedded in the app somehow. Therefore, I just copied the 3 real separate jars into the app project in Assets and set their buildaction = AndroidJavaLibrary. It worked great.

  Obviously, solution #1 is the right choice. I just wanted to explain everything for the benefit of others.

  So I am seeing different results when creating a binding project for ArcGIS (after tracking down a copy of joda-time-2.1.jar to resolve a bunch of dependencies):

  obj\Debug\generated\src\Org.Codehaus.Jackson.Map.Module.SimpleAbstractTypeResolver.cs(5,36,5,42): error CS0101: The namespace 'Org.Codehaus.Jackson.Map' already contains a definition for 'Module'
  obj\Debug\generated\src\Org.Codehaus.Jackson.Map.Module.SimpleDeserializers.cs(5,36,5,42): error CS0101: The namespace 'Org.Codehaus.Jackson.Map' already contains a definition for 'Module'

  obj\Debug\generated\src\Org.Codehaus.Jackson.Map.Module.SimpleModule.cs(5,36,5,42): error CS0101: The namespace 'Org.Codehaus.Jackson.Map' already contains a definition for 'Module'
  obj\Debug\generated\src\Org.Codehaus.Jackson.Map.Module.SimpleSerializers.cs(5,36,5,42): error CS0101: The namespace 'Org.Codehaus.Jackson.Map' already contains a definition for 'Module'

  I notice in the generated file __NamespaceMapping__.cs that Mono appears to camel case the namespaces for the generated C#, and this is probably ambiguating the meaning of Module (since Java has a lower-case namespace module, and a class in the same parent namespace Module. Is there any way to disable the auto-capitalization of namespaces in a binding project? It seems likely this has come up in the past, and might again in the future.

  PS. I just noticed these in the build log, too:

  Type com.esri.core.geometry.Geometry: FxDG naming violation: Type name 'Geometry' matches namespace part 'Geometry'.
  Type com.esri.core.symbol.Symbol: FxDG naming violation: Type name 'Symbol' matches namespace part 'Symbol'.
  Type com.esri.core.portal.Portal: FxDG naming violation: Type name 'Portal' matches namespace part 'Portal'.
  Type com.esri.core.renderer.Renderer: FxDG naming violation: Type name 'Renderer' matches namespace part 'Renderer'.
  Type com.esri.core.tasks.ags.query.Query: FxDG naming violation: Type name 'Query' matches namespace part 'Query'.
  Type com.esri.core.internal.catalog.Catalog: FxDG naming violation: Type name 'Catalog' matches namespace part 'Catalog'.
  Type com.esri.core.geometry.Geometry: FxDG naming violation: Type name 'Geometry' matches namespace part 'Geometry'.
  Type com.esri.core.symbol.Symbol: FxDG naming violation: Type name 'Symbol' matches namespace part 'Symbol'.
  Type com.esri.core.portal.Portal: FxDG naming violation: Type name 'Portal' matches namespace part 'Portal'.
  Type com.esri.core.renderer.Renderer: FxDG naming violation: Type name 'Renderer' matches namespace part 'Renderer'.
  Type com.esri.core.tasks.ags.query.Query: FxDG naming violation: Type name 'Query' matches namespace part 'Query'.
  Type com.esri.core.internal.catalog.Catalog: FxDG naming violation: Type name 'Catalog' matches namespace part 'Catalog'.
  

  PPS. I have gotten a bit further after discovering Metadata.xml as a way of removing chunks of java I don't need to call, however the bindings generator capitalizing getType() -> GetType() is obviously problematic for base object APIs that C# expects. Any way to turn off auto capitalization here as well?

  After some fighting, I have ArcGIS 10.1 (the brand new one) binding with the following lines added to Metadata.xml:

    remove-node path="/api/package[@name='com.esri.android.map.popup']"
    remove-node path="/api/package[@name='com.esri.core.geometry']"
    remove-node path="/api/package[@name='com.esri.core.internal']"
    remove-node path="/api/package[@name='com.esri.core.internal.widget']"
    remove-node path="/api/package[@name='com.esri.core.portal']"
    remove-node path="/api/package[@name='com.esri.core.symbol']"
  

  Note that the xml delimiters are culled as I wasn't sure how to get this forum to actually show the text with the delimiters in there (and pre wasn't cutting it).

  This is entirely preliminary, but I figured I would leave the info here in case anyone still cares.

  Hi there,

  I'm trying to achieve the same thing. Before I spend valuable time, could you please let me know, how you setup your binding projects.

  thanks, Chris

  @ShawnCastrianni, @GeoffEvans, and anyone else. I have to create a binding for Esri maps, but being relatively new to Android I'm having a bit of a problem. I've downloaded 10.2 of their SDK, unzipped it and added

  arcgis-android-api.jar
  arcgis-android-app-framework.jar

  as embedded jars,

  and

  jackson-core-lgpl-1.9.5.jar, jackson-mapper-lgpl-1.9.5.jar and jcifs-1.3.17.jar as embedded reference jars

  to an Android Java Bindings Library.

  I just can't get past what appears to be the same issue that Shawn had with the MultiPath class - MultiVertexGeometry does not exist in Com.Esri.Core.Geometry

  I don't know what to do to resolve it. This is my first attempt at binding a library.

  I took another crack at binding ESRI and I was successful the second time around with more experience.

  Below is the final metadata.xml file I came up with that I am using in production with great results. This metadata.xml file was created against 10.1.1 of the ESRI SDK. Hopefully, you won't have to make any changes to make it work against 10.2 ESRI.

  <metadata> <remove-node path="/api/package[@name='com.esri.android.map.popup']" /> <remove-node path="/api/package[@name='com.esri.core.geometry']/class[@name='Geometry']/field[@name='m_description']" /> <remove-node path="/api/package[starts-with(@name,'com.esri.core.internal')]" /> <remove-node path="/api/package[@name='com.esri.core.portal']" /> <remove-node path="/api/package[@name='com.esri.core.symbol']/class[@name='PictureMarkerSymbol']/constructor/parameter[@type='java.lang.String']/.." /> <attr path="/api/package[@name='com.esri.core.geometry']/class[@name='Geometry']/method[@name='getType']" name="managedName">getGeometryType</attr> <attr path="/api/package[@name='com.esri.core.geometry']/class[@name='Envelope']/method[@name='getType']" name="managedName">getGeometryType</attr> <attr path="/api/package[@name='com.esri.core.geometry']/class[@name='Line']/method[@name='getType']" name="managedName">getGeometryType</attr> <attr path="/api/package[@name='com.esri.core.geometry']/class[@name='Point']/method[@name='getType']" name="managedName">getGeometryType</attr> <attr path="/api/package[@name='com.esri.core.geometry']/class[@name='Polygon']/method[@name='getType']" name="managedName">getGeometryType</attr> <attr path="/api/package[@name='com.esri.core.geometry']/class[@name='Polyline']/method[@name='getType']" name="managedName">getGeometryType</attr> <attr path="/api/package[@name='com.esri.core.geometry']/class[@name='MultiPoint']/method[@name='getType']" name="managedName">getGeometryType</attr> <attr path="/api/package[@name='com.esri.core.symbol']/class[@name='MultiLayerSymbol']/method[@name='copy']" name="return">com.esri.core.symbol.Symbol</attr> <attr path="/api/package[@name='com.esri.core.geometry']/class[@name='MultiPath']" name="extends">com.esri.core.geometry.Geometry</attr> <attr path="/api/package[@name='com.esri.core.geometry']/class[@name='MultiPath']" name="extends-generic-aware">com.esri.core.geometry.Geometry</attr> <attr path="/api/package[@name='com.esri.core.geometry']/class[@name='MultiPoint']" name="extends">com.esri.core.geometry.Geometry</attr> <attr path="/api/package[@name='com.esri.core.geometry']/class[@name='MultiPoint']" name="extends-generic-aware">com.esri.core.geometry.Geometry</attr> <attr path="/api/package[@name='com.esri.core.tasks.ags.geocode']/class[@name='LocatorGeocodeResult']" name="extends">java.lang.Object</attr> <attr path="/api/package[@name='com.esri.core.tasks.ags.geocode']/class[@name='LocatorGeocodeResult']" name="extends-generic-aware">java.lang.Object</attr> </metadata>

  Thanks @ShawnCastrianni, Unfortunately I'm still getting build errors and hundreds of warnings with this metadata. I did manage to mangle it yesterday to build, but it crashed spectacularly at runtime.

  Can I ask you, which .jars have you included in the project. I have the 5 I mentioned above - do you have the same, with the same build actions?

  Do you have to include any of the .so files ? sorry for the really noob questions, if I could have picked an easier first binding project I would have

  Cheers,
  Greg

  when I get back to my computer, I will post a more detailed answer. however, it will be based on esri 10.1.1. if you guys are trying to get 10.2 to work, that could explain all of your errors. could you guys try 10.1.1 instead to see if you can get that to work in the meantime until I get back to my computer. I can attach my csproj file.

  Interesting. It looks like ESRI has created a whole new page for Android SDK. The new one has the link to 10.2, but the old one is still up and contains all the previous downloads, including 10.1.1 u1. Here is a direct link:

  downloads.esri.com/secure/FE33D4997D59028602DEB3B3AC4F87EB/0D3F0765CE469F9E4C77C98023907DE1/528BED67/ArcGISAndroidSDK_v10.1.1-u1.zip

  If that direct link doesn't work, here is a top level page that will reveal a link to 10.1.1

  resources.arcgis.com/en/communities/runtime-android/

  November 2013 edited November 2013

  Here are step by step instructions for getting 10.1.1 u1 to work:

  1. Download ArcGISAndroidSDK_v10.1.1-u1.zip file from ESRI
  2. Extract the zip somewhere and notice that its contents is that of an Eclipse plugin
  3. Locate the specific plugin jar called com.esri.arcgis.android.core_10.1.1.201306271100.jar and extract it somewhere
  4. The contents of this plugin jar contains the real esri sdk binaries that you want: ArcGIS_Android.jar, jackson-core-lgpl-1.9.5.jar, jackson-mapper-lgpl-1.9.5.jar, armeabi/libruntimecore_java.so, and armeabi-v7a/libruntimecore_java.so. Note: it is these last two binaries that are the reason version 10.1.1 of Android ESRI sdk does NOT work on the fast Intel based simulator. These two binaries are only for the ARM simulator. Supposedly, version 10.2 would have similar binaries for x86 platform.
  5. Start Xamarin Studio and create a brand new Android binding project
  6. Add the three jars: ArcGIS_Android.jar, jackson-core-lgpl-1.9.5.jar, and jackson-mapper-lgpl-1.9.5.jar to the Jars directory of your binding project
  7. Set the build action for ArcGIS_Android.jar to be EmbeddedJar, and for the other two jackson jars to be EmbeddedReferenceJar
  8. Now you must tweak the metadata file to get a good compile. With an empty metadata file, I get 5 errors and 202 warnings. The more functionality you want to work, the longer you have to tweak the metadata file. I had to make some decisions of cutting out some functionality just to make the binding process go faster. So I cut out things like map popup which you can see in the very first line of my metadata file posted above in this thread
  9. Paste in my metadata file posted above into your version of your binding project and rebuild. You should get 0 errors and 159 warnings. Yes, there are a lot of warnings just because I didn't want to spend time looking at them. However, if anything did not work during runtime of my esri android app, then I would take the time to see if it was a binding problem and fix it. Using the metadata file posted above, I got all the things I needed working fine, like feature layers, custom rendering with symbols, graphics layers, routing, location, etc.
  10. If everything goes fine, you should be done with the binding project. Now create another android application project to test out the runtime of your binding project and add it to the same solution that was created for you when you created your binding project. Set this new android application project as your startup project for this solution.
  11. Notice that during our binding project steps, we never used the native binaries libruntimecore_java.so files mentioned above. That is because those are only needed for runtime. We will use those here in our test android application project
  12. In your test android application project should be an Assets directory. Add both the armeabi* directories that contain the libruntimecore_java.so files to the Assets directory. Make sure you add the parent armeabi* directories and not the libruntimecore_java.so files directly
  13. Set the build action on both libruntimecore_java.so files as AndroidNativeLibrary
  14. Add a reference to the binding project you created above in this test android application project
  15. Now edit the Main.axml layout file and remove the Button UI element so that the layout file only contains a LinearLayout and give that LinearLayout an ID so that it can be referenced from code.
  16. Edit the MainActivity.cs file to try and exercise ESRI arcgis stuff. I have an included my MainActivity.cs file below.
  17. Run a build. Sometimes the build will fail because the build process itself runs out of memory. I don't know if there is a nice fix for this yet, but the way I fix it on my Mac is to exit Xamarin Studio, open a command prompt and do: export _JAVA_OPTIONS="-Xmx1g", then start Xamarin Studio from the command line so that it picks up this java option change. If you start Xamarin Studio from the normal icon, this command prompt setting is ignored. This gives the build process 1Gig of ram to do its job.

  I have attached a zip of my solution with both projects below. I have deleted all the ESRI files since I am not allowed to redistribute those.

          {
              base.OnCreate (bundle);
              SetContentView (Resource.Layout.Main);
              LinearLayout contentV = (LinearLayout)FindViewById (Resource.Id.ContentView);
              MapView esriMap = new MapView (this);
              esriMap.EnableWrapAround(true);
              esriMap.SetEsriLogoVisible (true);
              esriMap.LayoutParameters = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MatchParent,ViewGroup.LayoutParams.MatchParent);
              contentV.AddView(esriMap);
              //Add a basemap layer
              Layer basemapLayer = new OpenStreetMapLayer ();
              basemapLayer.Name = "Basemap";

  No, I think I'll have to try with 10.1 - I get an initialisation error. The spectacular runtime crash I hit before was actually a build error (Java heap), once I figured that out the build worked. I'm on my way to work where I can get 10.1 and will try again.

  I haven't fully tested this yet, but I went through my procedure to get 10.2 to compile. Below is my metadata.xml file. It is similar to FrankSmith's but I think it doesn't remove as much as his. I actually need the query and renderer stuff so I did not remove all of that as he did. Also, I will not bother posting the full solution zip since the procedure is the same as my lengthy post except:

  1. I set both of the arcgis* jars as EmbeddedJar and all of the other jars as EmbeddedReferenceJar.
  2. Add all three platform native directories to the Assets folder of the test project. This allows you to FINALLY run ESRI apps inside the emulator since they now include x86 binaries.
  3. I also added Mono.Android.Support.V4 to the references of the binding project to fix some of the compile issues.

  Here is the metadata.xml file:

  I have been trying to get ESRI 10.2 working with an Android application and all the above has been very useful, so thank you!

  But... I'm using Visual Studio 2012 and it seems as if the binding project isn't being created correctly. I add it as a reference to my Android application but it doesn't pick up "Com.Esri.Android.Map.xxx" (it thinks the reference is missing). I also try to open the reference in the object browser, but it doesn't expand out.

  If I create the binding project using Xamarin Studio and then add it to my VS2012 application everything works fine. So it suggests there's a problem creating the binding project in Visual Studio.

  I've tried creating the binding project in VS2010 too and use .Net 3.5, 4.0 and 4.5, but still no joy.

  Any ideas?

  Thanks,

  Shawn;

  I'm hoping you (or someone else) can help? I'm fairly new to Xamarin and trying to figure out how to use Esri on an Android device.

  I've downloaded your sample application and included the necessary ArcGIS files. Everything compiles just fine, but it blows up at run time on both the Arm Emulator and my Samsung S3.

  It crashes here:

      public MapView (global::Android.Content.Context p0) : base (IntPtr.Zero, JniHandleOwnership.DoNotTransfer)
                  {
                      if (Handle != IntPtr.Zero)
                          return;
  
                      if (GetType () != typeof (MapView)) {
                          SetHandle (
                                  global::Android.Runtime.JNIEnv.StartCreateInstance (GetType (), "(Landroid/content/Context;)V", new JValue (p0)),
                                  JniHandleOwnership.TransferLocalRef);
                          global::Android.Runtime.JNIEnv.FinishCreateInstance (Handle, "(Landroid/content/Context;)V", new JValue (p0));
                          return;
                      }
  
                      if (id_ctor_Landroid_content_Context_ == IntPtr.Zero)
                          id_ctor_Landroid_content_Context_ = JNIEnv.GetMethodID (class_ref, "<init>", "(Landroid/content/Context;)V");
                      SetHandle (
                              global::Android.Runtime.JNIEnv.StartCreateInstance (class_ref, id_ctor_Landroid_content_Context_, new JValue (p0)),
                              JniHandleOwnership.TransferLocalRef);
                      JNIEnv.FinishCreateInstance (Handle, class_ref, id_ctor_Landroid_content_Context_, new JValue (p0));
                  }
  

  It crashes on the last line of that method (JNIEnv.FinishCreateInstance)
  with this error:

  I am not so sure the "Unable to create external cache directory" is an actual error. If you use DDMS to view the entire device log, do you see anything else useful? Maybe you can attach your full log to a post and myself or someone else can spot something.

  If you followed all the steps in my post, then I am not sure at the moment. Maybe something you can try in the short term is to switch to android-17 (4.2.2). I can see from your logcat that you are using android-19. I have my app running with esri against android-17 so maybe something in the android sdk changed that makes esri not compatible with android-19. I doubt this is the answer, but is something to try. When I get a chance, I will try my test program against 19 and see what happens.

  With this new information, I would double check the Build Action in your Xamarin project of all of the ESRI native files, both jars and so's. libruntimecore_java.so should be AndroidNativeLibrary, arcgis-android.*.jar should be EmbeddedJar, all other jars should be EmbeddedReferenceJar. The total number of jars should be 5. 2 esri specific and 3 extra dependency jars.

  This step is very easy to forget so that is why I suggest double checking. When Java loads a class, it must also locate all dependent classes which would come from these extra 3 jars so if they are not marked with EmbeddedReferenceJar, they probably can't be found at runtime.

  I downloaded your sample project linked in this thread. Added the 10.1.1 esri jar files and the two .so files. I'm trying to run this on both a real device (Samsung S3) and the google emulator(ARM).

  In the Core project under Jars

  • ArcGIS_Android.jar (EmbeddedJar)
  • jackson-core-lgpl-1.9.5.jar (EmbeddedReferenceJar)
  • jackson-mapper-lgpl-1.9.5.jar (EmbeddedReferenceJar)

  In the Android Project under Assets

  • armeabi\libruntimecore_java.so (AndroidNativeLibrary)
  • armeabi-v7a\libruntimecore_java.so (AndroidNativeLibrary)

  I just triple checked these to make sure I didn't miss the settings and they are correct.

  Also - I just tried API 17 - still a no go.

  For ESRI 10.1.1, that all sounds correct. I have never tested ESRI 10.1.1 with android-19, so I would still try android-17 just to see what happens. For ESRI 10.2, they have a different set of jars so my previous post before this one says how to set the BuildAction for those 5 jars.

  Unfortunately, nothing you have said sounds wrong. Until I get a chance to try a few things, my only short term suggestion is android-17.

  Android API Level 17 didn't help - I get the exact same crash.

  I've posted on S/O - maybe someone else can help and/or benefit if a solution is found. I'm sure I must be doing something wrong - since so many people here have it working, I just wish I knew what!

  Just tried to bind the latest version of the SDK (10.2.3) and to make it work I had to add the following line to the Metadata.xml file

  <remove-node path="/api/package[@name='com.esri.core.tasks.query']/class[@name='OutStatistics']" />

  For some reason when tested in GenyMotion the screen stays black, or just displays a grid. It's working fine on a phisycal device anyway.
  As a reminder, remember to add the right permissions to the app manifest!

  Hi to everyone,

  I successfully created an Android esri map project using latest 10.2.3 release. Everything seems to work just fine except from the esri map events like esriMap.OnLongPressListener. How can i use this listener from c#?

  Thanks
