There are still some major failures with the UE4 engine. Especially when converting a project from an older build to a newer like 4.2.1 to 4.3. Several XML files don’t get updated.
\Build\Android\AndroidManifest.XML this file isn’t updated between engine versions mine was missing a ton of play services and admob related entries.
\Build\Android\proguard-project.txt this file also wasn’t updated and was missing a lot of entries going from 4.2.1 to 4.3
\Build\Android\res\values\GooglePlayAppID.XML this file doesn’t seem to follow the documentation from google. Get Started with Play Games Services for Android | Google Developers
as it only holds the app_id and no achievement or leaderboard ID’s at all. I couldn’t find any relations to the GooglePlayAppID.XML file at all in the Google documentation
according to Google the \Build\Android\res\values\folder should hold a ids.xml file that contains all the specific ID’s related to your app/achievements/leaderboards
To run the game, you need to configure the application ID as a resource in your Android project. You will also need to add games metadata in the AndroidManifest.xml.
- Open res/values/ids.xml and replace the placeholder IDs. If you are creating an Android game from scratch, you will need to create this file first.
Specify your application ID in the app_id resource.
Specify each achievement ID that you created earlier in the corresponding achievement_* resource.
Specify each leaderboard ID that you created earlier in the corresponding leaderboard_* resource.
- Open AndroidManifest.xml and enter your package name in the package attribute of the element. If you are creating an Android game from scratch, make sure that you also add the following code inside the element:
The only way to fix this is by deleting the **Application\Build and **Application\Intermediate folders. This will get rid of the old XML files and make sure the updated ones will be build ones you enter the Project Settings and make the Android files writable.
I also want to thank KRushin for providing me with some useful feedback on these subjects.
