You can solve it using the DocumentTreeIntent if you make it allow permission for the WhatsApp folder explicitly for android 11 here is how you can do that.
if (Constants.isPackageInstalled(getActivity(), "com.whatsapp")) {
Intent intent;
StorageManager sm = (StorageManager) getActivity().getSystemService(STORAGE_SERVICE);
String statusDir = getWhatsupFolder();
String str = "android.provider.extra.INITIAL_URI";
if (Build.VERSION.SDK_INT >= 29) {
intent = sm.getPrimaryStorageVolume().createOpenDocumentTreeIntent();
String scheme = ((Uri) intent.getParcelableExtra(str)).toString().replace("/root/", "/document/");
String stringBuilder = scheme +
"%3A" +
statusDir;
intent.putExtra(str, Uri.parse(stringBuilder));
} else {
intent = new Intent("android.intent.action.OPEN_DOCUMENT_TREE");
intent.putExtra(str, Uri.parse(statusDir));
}
intent.addFlags(2);
intent.addFlags(1);
intent.addFlags(128);
intent.addFlags(64);
startActivityForResult(intent, REQUEST_ACTION_OPEN_DOCUMENT_TREE);
return;
}
before using this code you must check if WhatsApp is installed or not so the first check is for that here is the code for that.
try {
context.getPackageManager().getPackageInfo(packageName, 0);
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
after granting permission you must retrieve files via this code
private DocumentFile[] getFromSdcard() {
DocumentFile fromTreeUri = DocumentFile.fromTreeUri(requireContext().getApplicationContext(), Uri.parse(namedataprefs));
if (fromTreeUri != null && fromTreeUri.exists() && fromTreeUri.isDirectory() && fromTreeUri.canRead() && fromTreeUri.canWrite()) {
return fromTreeUri.listFiles();
}
return null;
}
DocumentFile[] allFiles = getFromSdcard();
//to get signal file path
String path = allFiles[0].getUri().toString();
you can get further details about document tree intent from the below code its just for understanding purposes
