Hello friends,

After upgrade to Xamarin 4 and also the Google Play services to v27 with AppCompat and all related. When compiling the Android version I get this error:

/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.targets: Error: Tool exited with code: 1. Output: /Users/demo/projectcrm.Android/obj/Debug/resourcecache/053893A3E164BC46F1518CFC64246007/AndroidManifest.xml:28: Tag <provider> attribute authorities has invalid character '$'.

Find attached the AndroidManifest file content.

Any idea why this could be happening?

Thanks in advance

    I've narrowed down the issue to an update in Xamarin.GooglePlayServices.Measurement

    basically it adds in the manifest this line
    <provider android:authorities="${applicationId}.google_measurement_service" android:exported="false" android:name="" />

    basically there's a new var "${applicationId}" that should get replaced with our applicationID , so, where do we define that variable ???

    in "plain android" :

    I was able to solve the issue. I had the package Xamarin.GooglePlayServices.Measurement, so I removed it and it started to compile just fine, for some reason this package was added mistakenly due we do not need it.

    I don't know why Xamarin is ignoring this while most newer versions of GPS packages have a dependency on this ********* Xamarin.GooglePlayServices.Measurement!!!!

    Some people were able to fix it by adding a piece of code to gradle:

    android {
        defaultConfig.applicationId = ""

    But guess what... we don't use Gradle in Xamarin so we are left we no choice! Do something NOW.

    The bests I could do to fix my problem with that package was to rollback to version 27.0.0 of GCM package that doesn't depend on Measurement.

  • How you rolled back to earlier version of GCM. I'm also stuck in this issue.... I downloaded the GCM from nuget package manager and now the current version is and it is creating the same problem which you solved by downgrading.

    Any luck / solution on this one ? We did an upgrade on the GCM package (v29) which now depends on the Measurement package, causing this weird build error.

    Having the same issue with the newest version. Did it work properly doing a rollback to version 27?
