Androidx library support

The latest build tools for Android have not replaced many support libraries with androidx versions.
See https://developer.android.com/jetpack/androidx/migrate

These should be used in place of older android support libraries. However some changes to the gradle.properties file is required to integrate these libraries. The following lines need to be added.

android.enableJetifier=true
android.useAndroidX=true

The only way I can see to include these lines is to export the project and edit the build that way. Does anyone know of a way to edit the gradle.properties file through unity and create from the editor? And failing this, is this something Unity will be working on soon? Changing to Androidx libraries will be very urgent soon.

Cheer.

 

Use this callback interface to update the gradle.properties file instead of exporting to android project, which is obviously very tedious. Hope it helps!

 

Have a look over here to automate patching of gradle.properties file. You can comment the first method and use
EnableJetifierIfRequired method alone for your scenario.

Thanks,
VB Team

 

Even with jetifier options added to the gradle.properties, build fails with:

Is there something else that should be added? I've tried both patching and non-patching gradle template via play services resolver, w/o any luck so far. It generates same error.

 

can you give a try with gradlew build --stacktrace or --scan in Temp/gradleOut folder once and pass me the results. The data you shared above doesn't seem to have much info.

 

Do I need to export project for that one? I was building from Unity.

Edit: Okay, I think it should work with full stack trace enabled from the Player settings. Need to try that.

 

Here's a stacktrace:

@Voxel-Busters Okay, I've seems to found out what's causing this, and its unrelated to the AndroidX (well kinda related).

Play Services Resolver somehow extracted duplicates of the dependencies from the Facebook SDK, causing the error above. Looks like I need to cleanup facebook imported files.

--stacktrace advice was extremely useful! Thank you!

 

Yes, looks so from the log.

Anyways, glad you sorted out the issue. Good luck!
