Describe the problem:
Bazel can only generate apks and Play Store expects aab. I am trying to modify the Bazel build process to generate aab. I am getting NullPointerException.

If there is easier way to convert an apk to an aab for Play Store, please let me know.

Hi @ya332, Are you building on windows desktop ?

[ya332]

I am building for Android on Windows 11 Laptop.

[sgowroji]

@ya332 In https://google.github.io/mediapipe/getting_started/install.html#installing-on-windows, there is a note saying that building MediaPipe Android apps is still not possible on native Windows. Please do this in WSL instead.

[ya332]

I am using WSL and can successfully build apk. However, I don't know how to build aab. Google Play store accepts only aab and not apk

[sgowroji]

Have you tried this https://medium.com/mobile-app-development-publication/android-apk-to-app-bundle-made-simple-e12c52e8641

[ya332]

The medium article uses Gradle. Mediapipe hair segmentation example uses Bazel. I need to modify the Bazel build process to produce AABs. Do you know how I can do that?

Hi @ya332, We can see a feature request on the same on bazel for AAB bazelbuild/bazel#11497. Present we can't do AAB in MediaPipe with bazel. If there is any update we will let you know soon. Thanks!
