dynamically add pictures to gallery widget

Question

Is there a good way to add new image resources(from SD card) to a gallery widget at runtime?

Answer 1

Send broadcast to MediaStore Content Provider when you add a file

sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile(imageAdded)));

Working for devices before KitKat

sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED,
              Uri.parse("file://"+ Environment.getExternalStorageDirectory())));

Also have a look at this

Working in Lolipop and should also solve kitkat issues.

ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.DATA,"file path");
values.put(MediaStore.Images.Media.MIME_TYPE,"image/jpeg");
mContext.getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,values);

Add Permission.
