android.add_src option in buildozer.spec causes error

[Sahil Mahajan]

Hello, I am trying to use a java file in my android project. I wrote a .java file and edited the buildozer.spec by using the android.add_src option. When I run buildozer android debug, I get the error "subprocess.CalledProcessError: Command '['ant', 'debug']' returned non-zero exit status 1."

Moreover, all subsequent build attempts fail with the same error, even when I uncomment the android.add_src option. However, if I delete the apk and the .buildozer file, comment out the android.add_src option, and run buildozer android debug again, the apk builds successfully. When I uncomment out the android.add_src option and run buildozer android debug after this, I get the error message again. It seems that my using the android.add_src option breaks something in buildozer.

I checked online for solutions to this error. I tried installing libncurses5 and the rest, and also tried running ~/.buildozer/android/platform/android-sdk-21/tools/android and downloading Android SDK Build-tools Rev. 20. These solutions worked before when I ran into the same problem, but now they no longer work and I am stuck.

Please let me know if there is any more information that might be helpful in finding a solution. Thank you.

There's probably something invalid about the src you add. Try navigating to the python-for-android dists directory in buildozer (something like .buildozer/android/platform/python-for-android/dists/distname) and run 'ant debug' to see the specific debug output.

That worked. I ran ant debug in /.buildozer/android/platform/python-for-android/dist/distname, and found an error in my .java file from the output. I found what was invalid and corrected it. Running ant debug now builds successfully, and running buildozer android debug builds the apk successfully. Thank you so much for your help!
