//external:android/crosstool depends on @androidndk//:default_crosstool in repository @androidndk which failed to fetch. no such package '@androidndk//': Could not read RELEASE.TXT in Android NDK: /home/nd/Android/Sdk/ndk/RELEASE.TXT (No such file or directory)

I followed the instruction to set up Android Studio with MediaPipe. When I import the build file with bazel, error occured.

I opened the ndk folder but can't find RELEASE.TXT. But I did installed ndk in the Adroid Studio. Please give me some hint about this problem. Thanks anyway. :)

Can you report the following system information to help us understand your issue:

• OS Platform and Distribution (e.g., Linux Ubuntu 16.04)
• Bazel version
• Android Studio, NDK, SDK versions (if issue is related to building in mobile dev environment
• Your environment variables: $ANDROID_HOME and $ANDROID_NDK_HOME

Moreover, do you install NDK by yourself? If it's installed by Android Studio, it's likely to be put into Android/Sdk/ndk-bundle/ instead of Android/Sdk/ndk/. Have you modified the WORKSAPCE file?

[JimReno]

Thanks for reply. Sure. The system information are listed below:

• OS Platform and Distribution : Linux Ubuntu 16.04
• Bazel version:0.29.0
• Android Studio SDK version: 29 NDK version: 20.0.5594570
• environment variables: $ANDROID_HOME:/home/nd/Android/Sdk $ANDROID_NDK_HOME:/home/nd/Android/Sdk/ndk.
  

I follow the instruction and installed the NDK in Android Studio. And I didn't modified the workspace file.

I can reproduce this issue with Android Studio 3.5 on Linux now.
The latest Android Studio (3.5) puts the ndk libraries into Android/Sdk/ndk/<version number> instead of Android/Sdk/ndk-bundle/ . For your case, the $ANDROID_NDK_HOME should be /home/nd/Android/Sdk/ndk/20.0.5594570.

We will update install.md soon to mention this change. Thanks.

The instruction of setting up MediaPipe with Android Studio is updated. See install.md.

Dead link.

I must note that the official documentation at https://developers.google.com/mediapipe/framework/getting_started/android still does not note the correct way to determine the ANDROID_NDK_HOME. Had I not read this conversation, I wouldn't have known what to do either.
