I am trying to this code. Can someone tell me how can I get only .pdf files in my phone storage?
protected ArrayList<String> getPdfList() {
ArrayList<String> pdfList = new ArrayList<>();
Uri collection;
final String[] projection = new String[]{
MediaStore.Files.FileColumns.DISPLAY_NAME,
MediaStore.Files.FileColumns.DATE_ADDED,
MediaStore.Files.FileColumns.DATA,
MediaStore.Files.FileColumns.MIME_TYPE,
};
final String sortOrder = MediaStore.Files.FileColumns.DATE_ADDED + " DESC";
final String selection = MediaStore.Files.FileColumns.MIME_TYPE + " = ?";
final String mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension("pdf");
final String[] selectionArgs = new String[]{mimeType};
if (SDK_INT >= Build.VERSION_CODES.Q) {
collection = MediaStore.Files.getContentUri(MediaStore.VOLUME_EXTERNAL);
} else {
collection = MediaStore.Files.getContentUri("external");
}
try (Cursor cursor = getContentResolver().query(collection, projection, selection, selectionArgs, sortOrder)) {
assert cursor != null;
if (cursor.moveToFirst()) {
int columnData = cursor.getColumnIndex(MediaStore.Files.FileColumns.DATA);
int columnName = cursor.getColumnIndex(MediaStore.Files.FileColumns.DISPLAY_NAME);
do {
if (new File(cursor.getString(columnData)).exists()) {
pdfList.add((cursor.getString(columnData)));
Log.d(TAG, "getPdf: " + cursor.getString(columnData));
//you can get your pdf files
}
} while (cursor.moveToNext());
}
}
return pdfList;
}
above code work fine upto android 10 with requestLegacyExternalStorage = true but in android 11 cursor.moveToFirst() geting false
Add these two line to your manifest:
<uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE"
tools:ignore="ScopedStorage" />
