Alternative implementation of Environment.getExternalStorageDirectory() – deprecated API – for your Android App – SDK/ API level 30 and above.

In this video it shows alternative approach/ API to nvironment.getExternalStorageDirectory() which is deprecated in API level 29.

In this it shows how one can use storageVolume.getDirectory() as an alternative which is added in API level 30.

I hope you like this video. For any questions, suggestions or appreciation please contact us at: https://programmerworld.co/contact/ or email at: programmerworld1990@gmail.com
