Description Jon Dick 2017-04-04 14:24:30 UTC
With Google Play Services, we heavily rely on the merging of AndroidManifest.xml files from the .AAR files we bind.

Currently, when an AndroidManifest.xml file inside of an .aar contains something like this:

  <manifest package="com.google.android.gms.auth.api" ... >
      <activity android:name=".signin.internal.SignInHubActivity" ... />

We expect the activity to be merged into our app's manifest with the package name prefixed to the name, so the result would be:
      <activity android:name="com.google.android.gms.auth.api.signin.internal.SignInHubActivity" ... />

This is not happening in the latest beta channel (Xamarin.Android, instead we get the activity merged like this:
      <activity android:name=".signin.internal.SignInHubActivity" ... />

This breaks anyone's app trying to use these libraries where the declarations are required.

This appears to be happening to for service dellarations too, so I'd expect it's a general problem with any element (broad cast receivers, intent filters, etc).

If you want to reproduce this, create a new android app project.

Add the Xamarin Google Play Services - Auth NuGet package to your app.

Build the app, and look at your obj/Debug/android/AndroidManifest.xml file, and note the entries with the ".signin.internal.SignInHubActivity" entry...

Sadly, I don't think this did ever work correctly.  This code appears to be largely unchanged:

Here is some more documented info on how the merge process should be handled:

In the meantime we've adjusted Xamarin.Build.Download to perform the `android:name` attribute merging with the package name from the source manifest file.


Xamarin.Build.Download v0.4.4-beta1 and newer should have this enabled.
