Updating dependencies, SDKs, and more

[stevenzeck]

What's been updated

1. Update all dependencies to latest versions.
2. Update compile and target SDKs to 34.
3. Update Gradle to 8.0, and AGP to 8.1.0.
4. Use Java 17 (required by AGP update).

Important notes

1. KSP has replaced Kapt for Room. There is an issue with Room 2.5.2 and Kotlin 1.9.0 that won't be fixed until 2.5.3. One of the workarounds in the issue is to use KSP instead of Kapt. Kapt is in maintenance mode and KSP offers significant performance improvements.
2. With Kotlin 1.8, we don't need to declare kotlin-stdlib-jdk7 or 8 as they have been merged into a straightforward kotlin-stdlib. https://kotlinlang.org/docs/whatsnew18.html#updated-jvm-compilation-target.
3. android.nonTransitiveRClass defaults to true with the new AGP version. Because of this, when accessing IDs from external libraries, you have to prefix it with the namespace. For example, R.id.search_close_btn is now androidx.appcompat.R.id.search_close_btn.
4. If BuildConfig is needed for individual modules, buildConfig = true must be added to the buildFeatures block in build.gradle.kts for that module.

What else changed

1. When targeting Android SDK 34 you must add android.permission.FOREGROUND_SERVICE_MEDIA_PLAYBACK in order for TTS or Audiobook playback to work.

@mickael-menu @qnga Please review, especially the Kotlin file changes.

I tested everything except for LCP. But please test with your devices too.

[mickael-menu]

Thanks @stevenzeck, I tested again the various formats with LCP too.

Does this change have consequences? Maybe these resources cannot be overridden any more.

[stevenzeck]

This is actually because android.nonTransitiveRClass defaults to true with the updated AGP version.

Another fix would be to set that to false in gradle.properties, then we can continue using R.id.something instead of package.namespace.R.id.something. There is only one other place this was necessary and it was in the testapp.

I confirm that we can still override PSPDFKit strings with these changes, from an app's module. I tried with this:

<string name="pspdf__action_menu_copy">Test</string>

Looks to be an issue with ExoPlayer in which the test app requires android.permission.POST_NOTIFICATIONS. google/ExoPlayer#10884

[mickael-menu]

@stevenzeck The ExoPlayer DownloadService is not used in the toolkit, so it should not be required. Did you encounter an issue with the Test App?

[mickael-menu]

So apparently we need this permission even without using the DownloadService, because otherwise the linting step fails. See this comment: google/ExoPlayer#10884 (comment)
