[3.2] Godot Android Subview Implementation

[m4gr3d]

Now that version 3.2.3 is released(!), this PR proceeds to merge the Godot Android subview implementation back into the 3.2 branch for release for Godot v3.2.4.

The feature addresses godotengine/godot-proposals#1064 and enables the ability to embed Godot as a subview within an Android app/game.

Note: The feature is already within the main branch.

Thank you! This is probably one of the best features for Android at the moment! <3

Thanks!

Deleted 3.2-android-subview Godot branch as well.

@m4gr3d thanks for the great work! I'm hoping to use this to include a minigame in an existing app I wrote. Do you have any tips on how I can use your modifications? I built the 3.2 branch (150f9ce) from github for mac (so it should include these changes) and also the android libraries which allowed me to deploy the game on my Pixel 3 phone.

My only confusion is how to use it as a subview as the Godot interface only seem to give me export options for APK or AAB. Is there a way to use it as a library module or does this patch create a separate activity that I should bundle with my existing app (manually copy the *.so / gscript files?)

@falcon4ever I'm working on a write-up for how to use the capability for when this version goes stable. I'll share it early when it's in a decent state.

Just to confirm, are you using Android Studio to develop and build your existing app?

[falcon4ever]

Thanks! Yes I'm using Android Studio to build the existing app.

I have some experience with the NDK/jni (I used to port openFramework apps to Android) and was hoping to see if Godot works in a similar way. Basically if it exports to a separate Android Studio project I would be all set (assuming it's a matter of merging the Godot activity/fragment, game scripts & assets and the *.so files in libs).

@falcon4ever Hi, I'm currently looking at this feature now, and I made android project (which can be opened by android studio), from godot editor and it launches fine. But, after that, I'm look for how can I make subview godot scene with this feature and how can I make insert event to game from the android code and get event from the godot to android. Do you have any rough documents for this? I can't find any of those for now.

[m4gr3d]

@wangmir A set of instructions will be provided when Godot 3.3 is near stable for how to leverage the feature.
Stay tuned!

@wangmir Unfortunately I didn't have time to continue figuring out how to insert the code into my existing project (AS Arctic Fox 2020.3.1 Canary 11).

Good to hear that :) I'll wait for that! Anyway, can I test 3.3 feature that u mentioned at the 3.3 branch too for now?

@m4gr3d I am looking for the documentation of this implementation, but I have not found it. Who can help me? I'm very anxious to implement this in my android project，thank you！

[madhawa-se]

@humbinal me too. Did you find a clue ?
