Error. error=13, Permission denied in Android Q(10)

[jhui20130703]

The targetSdkVersion<=28 used in the development project before, the audio conversion is normal. Later, I changed targetSdkVersion=29, and running the project found that AMR conversion to MP3 failed.
The exception message:
java.io.IOException: Cannot run program "/data/user/0/package name/files/ffmpeg": error=13, Permission denied,
Please help me with the author and developers. thank you all.

From Android Q onwards, you cannot execute binaries in your app's private data directory.
From the issuetracker: https://issuetracker.google.com/issues/128554619

Change only on Build.gradle file targetSdkVersion 29 to 28 and Re-Install your app on your device - It is resolved your permission issue for temporary because of the targetSdkVersion 29 is required platform for released build on play store so I suggest to you use this library

Try adding this line to your Manifest file, inside the application tag:

android:requestLegacyExternalStorage=true

This should solve the Write/Reading permissions problem.

I'm using the targetSdkVersion=30

I solved the same problem as below.
I solved the problem by using a different library.

I wrote it like this, but it's useless
