The application could not be started

Hi everyones i got a anoying problem:

The application could not be started. Ensure that the application has been installed to the target device and has a launchable activity (MainLauncher = true).

Things i do:

  • adb uninstall ; nothing happends

    • try to uninstal app from device: the app dont apeard, even like a fake app whith 0kb
    • Uninstall Mono Shared Runtine and Api from app
    • Check in another device

Nothing solve my problem and i dont know who i must do.

    Hey, see in your Manifest if you have an initial activity or see in the activity class, if haved the main launcher set in true.

    Please see my bug logged on this here:

    There are a few workarounds that you can use to get your app deploying again. Please see the bug description for more help.

    On a side note, please check what Juan has mentioned in the sense that you have an Activity in your obj/Debug/android/AndroidManifest.xml that looks similar to the following:

        <activity android:icon="@drawable/icon" android:label="App5" android:name="md593b8d625023f6802361dd1b8a6546be5.MainActivity">
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
