Include wav files in android app using buildozer

[Lorenz Jung]

Hi all,

I am trying to develop an android app using kivy. The app is supposed to play some wav files, when certain buttons are pressed. On my mac, everything works fine, the audio files are played.

I created an android APK using buildozer. In the buildozer spec file, I commented out the line which source files should be included, so that all filetypes are included. 

Nevertheless, when I start the app on my android device, it works fine until I hit the "Play Audio" button. Then it crashes, like it isn't able to access the audio file.

Do you have an idea? Do I maybe have to adress the audio files diffently in the .py file, like giving the absolute path from the android device? I am new to kivy programming, and very grateful for any hints! Thank you.

Regards 

Lorenz

Add wav to line 16 (source.include_exts) of your buildozer.spec

I already tried that, it still doesn't work. 

Do you have any other ideas?

You are assuming the crash is due to a problem with not finding the wavs. You should get an adb logcat of a run to be sure that is the problem.

Well, the logcat contains the following:

I/python  ( 2195):  IOError: [Errno 2] No such file or directory: '/Users/lorenz..../...file.wav'

I/python  ( 2195): Python for android ended.

The mentioned directory is on my computer, where I stored the wav files. So I assume in the .py file, I have to refer to a directory on my android device, where I store the wav files, right?

Yup. Relative path names are usually best e.g. "audio/file.wav" will find the wav file in a "audio" subfolder relative to your main.py. Not sure how you are specifying you file path now? If you still have hassles, try logging the output of "os.path.abspath(<filname>)" to see the full name the path resolves to, or "os.walk"  to explore what is you current folder...

Good luck

Using relative path names solved my problem. 

Thank you guys!
