Build in Android Studio (Gradle multidex) about quickstart-unity

[stewartmiles]

The `Error:Execution failed for task ':processDebugResources'.

Error: more than one library with package name 'com.google.firebase'problem looks like a bug on our end. This is a dummy AndroidManifest.xml to work with Unity's old build system, you can change the package name tocom.google.firebase.unity` to workaround this error.

The Manifest merger failed : uses-sdk:minSdkVersion 14 cannot be smaller than version 15 is very bizzare as we support API level 14 and above (see https://android-developers.googleblog.com/2016/11/google-play-services-and-firebase-for-android-will-support-api-level-14-at-minimum.html) . I just took a look at a local project and I'm seeing the highest requirement set to <uses-sdk android:minSdkVersion="14" android:targetSdkVersion="22" /> as expected. Have you taken a look at the merged AndroidManifest.xml to see which component is causing this?

The messaging AAR is located in Assets/Firebase/m2repository/com/google/firebase/firebase-messaging-unity. Copying just the strings.xml is a very bad idea, things will not work. You should be able to add Assets/Firebase/m2repository as a maven repo at the top of your Gradle file which would allow it to find firebase-app-unity and firebase-messaging-unity which include the proguard rules required for the plugin, in addition the messaging AAR includes the messaging service implementation.

This small problem and yes we solve this by rewrite
sdk android:minSdkVersion="14" android:targetSdkVersion="22" />
to android:minSdkVersion=15 because all our projects use this.

Yes. When I build with out it. App falls on dependency check.

May you provide example of build.gradle or android studio project archive?

Turns out the number of modifications you need to make should be pretty minimal - at least with our sample application - I've lined up fixes internally to hopefully get into our next release. I tested this out with Unity 5.5.0f3.

1. Replace firebase-messaging-unity-1.1.1.srcaar with the attached file. This simply changes a line in the AndroidManifest.xml from <application android:label="@string/app_name"> to <application>. This works around problems a missing reference to merging this package.
2. Delete Assets/Plugins/Android/firebase-messaging-unity-1.1.1 which should result in the Play Services Resolver component expanding it with the updated component.
3. Replace Assets/Plugins/Android/Firebase/AndroidManifest.xml with the attached file. This changes a line in the AndroidManifest.xml from package="com.google.firebase" to package="com.google.firebase.unity".
4. Run the Android Resolver (use the Assets --> Play Services Resolver --> Android Resolver --> Resolver Client Jars menu option).
5. Export the Android Studio project.
6. (We're working on a better solution for this step) Copy the contents of Assets/Plugins/Android/Firebase/libs/ to your_android_studio_project/src/main/jniLibs
