Windows and Android Studio - issue with libgg.so and libxp.so

[nilstk]

Hi development team,

I'm unsure if my issue is related to the missing support of Windows. Nevertheless, I'd like to notify you about it.

After downloading the project and importing it to Android Studio for APK compilation, I received the following error about a missing library:

Task :GoldenGateBindings:externalNativeBuildDebug FAILED
Build xp_x86
ninja: Entering directory `C:\tmp\gg\golden-gate\platform\android\goldengate\GoldenGateBindings.cxx\cmake\debug\x86'
ninja: error: '../../../../../../../../xp/build/cmake/android/x86/libgg.so', needed by '../../../../build/intermediates/cmake/debug/obj/x86/libxp.so', missing and no known rule to make it

Any idea on how to fix that?

Side note: On Linux it is the same issue. I had the hope it is a Windows issue initially.

Build command failed.

Having the same issue on MacOS with Android Studio 4.2
I followed all steps described in "Getting Started" and "Platform Android". The only thing I changed was updating the two references to the specific NDK version. No other changes.
I have all the CMAKE versions avalable and the conda gg environment is active. Anymore ideas what to check?

It was able to solve my issues above. The Android documentation lacks the hint that the library libgg.so must be compiled externally and cannot be compiled (as expected) by the Android NDK and Android Studio itself. Therefore, one is required to follow the "getting started"-guide and setup the build system on the host along with inv, conda, python etc. to be able to run "inv android.build", which compiles the required libgg.so

Yes, sorry about that. I will update the documentation to avoid the confusion in the future.
