Hello there,
- I have a custom android app that allows uploading of files (pdf,excel,doc,images).
- I'm able to upload such files from any path on the device until I was using Android 10. Now my device is upgraded to android 11, and I am facing uploading issue.
- I am able to pick file attachments from Downloads folder but not able to pick any attachments from other folders and external folders on the Andorid 11 device. I am facing this issue in my physical device as well as on Android Emulator . It will be of great help if someone helps me out on this issue.
Here is the source code of my Application for reference
MainActivity.java
public void addFiles() {
if (AppUtils.storageInitialCheck(getActivity())) {
AppUtils.storagePermisson(getActivity());

- If i try to pick file from folders apart from DOWNLOADS or from external storage the file path i am getting null (Please refer MainActivity.java code & also mentioned filepath in the AppLog).
It will be great help if someone helps me out on this issue.
