错误：发现多个<meta-data>元素</meta-data>

Question

I created an app (bundle: myApp.aab) (using cn1: Android build) and tried to upload it on google-console, but it was rejected with the following error:

An error occurred while running bundletool build-apks on your uploaded App Bundle. Ensure that your App Bundle is valid by running bundletool build-apks locally and try again. Error: Found multiple elements for key 'com.google.android.gms.version', expected at most one.

When I decompiled AndroidManifest.xml (using bundletool.jar on myApp.aab) I noticed that the following line appears twice:

<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />

This is obviously the cause of the error described above. This line appears only once in the 'build hints' (in cn1-settings: key=android.xapplication).

I tried to delete this <meta-data> tag (in the 'build hints'), but during the build process it was automatically added.

So the problem is that cn1 automatically generates this tag twice in the AndroidManifest.xml during the build process, and therefore google-console generates an error during the upload of the myApp.aab file.

What can I do to avoid this problem?

Answer 1

This might be a problem specific to Ant since that system used a somewhat flawed approach of modifying the build hints to inject additional meta-data. As a workaround, try unzipping the fullscreen ads cn1lib and removing that hint from the properties file at the root. Then rezip it and replace the existing file.

Remove the build hint android.xpermissions . It will regenerate without the meta tag. That might workaround the problem.
