Permission denied error

I am using this code to convert my mp3 file in m4a because I want to merge audio and video files and using mp4parser library for this. But I red somewhere that mp4parser only works with m4a audio format. When executing this code I am getting this error "/data/user/0/com.jiviz.m4a: Permission denied".......My audio file is in string format..Log - V/Mux-------: ======/storage/emulated/0/DCIM/Jiviz_2021_02_01_07_15_33.mp4======/data/user/0/com.jiviz.app/files/songs/312mp3

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