[Jagadeesh Mekala]

i want to access my android mobile through pyler or jnius. just for a sample i have written a code to vibrate my mobile when button clicked, i used buildozer to compile my python code to apk. but it's(apk) not worked in my android mobile..when i click the button app was closing automatically..by that i found only kivy ui is working but nadroid api is somethong error.. just send some information about this,..

need an example code with "android api+kivy" which can able to run on android by compiling with buildozer....

I think the plyer vibrate obsolete.

Look at

https://github.com/kivy/plyer/blob/master/plyer/platforms/android/vibrator.py

It uses Java's Vibrator.vibrate() with an integer argument which was was "depreciated"/redefined in Android API26

https://developer.android.com/reference/android/os/Vibrator.html#vibrate(android.os.VibrationEffect)

So perhaps the only route is pyjnius. This can be a challenge as there is no checking between Python and Java code.

The debugging instructions posted above will tell you where the problem is, but in the pyjnius case not why - enjoy the challenge.

Our friend Google points me to an example, I have no idea if it works:

I think the pattern argument would need to be a VibrationEffect
