Re: [kivy-users] Re: open/resume app from service

[Decave]

That because there is no application with package name 'org.kivy.touchtracer' on your android device.

Here is a complete example for the kivy launcher on Android.
Hopefully my problem gets more clear.

It works like it is described here:

    sound = SoundLoader.load("Bubamara.MP3")
    sound.play()
    time.sleep(1)
    sound.stop()
   
 
if __name__ == '__main__':
   
    # to see, if the service really gets started
    # play a soundfile.
    # place it in the service directory
   
    #play_sound()

    PythonActivity = autoclass('org.renpy.android.PythonActivity')
    Intent = autoclass('android.content.Intent')
    Context = autoclass('android.content.Context')
    activity = cast('android.app.Activity', PythonActivity.mActivity)
   
    # this line causes the error in kivys logfile:
    # jnius.jnius.JavaException: Unable to find a None method!
    manager = autoclass('android.content.pm.PackageManager')
   
    # this line crashes kivy
    # no error gets thrown
    #manager = activity.getPackageManager()
     
    intent = manager.getLaunchIntentForPackage("org.kivy.touchtracer")
    intent.addCategory(Intent.CATEGORY_LAUNCHER)
     
    activity.startActivity(intent)
   

Does someone know, if my problem is a generall restriction of what is possible with services? Or is it a bug or missing feature in kivy or pyjnius?
Or do I have to code it different?

Thanks for any help,
XR

You can use any installed package, the touchtracer is just an example.
If you install it from the play store, it should work
