Android file delete leaves empty placeholder in Gallery

Android has a cache of sorts that keeps track of media files.

Try this:

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

It makes the MediaScanner service run again, which should remove the deleted image from the device’s cache.

Looks like you also need to add this permission to your AndroidManifest.xml:

  <action android:name="android.intent.action.MEDIA_MOUNTED" />
  <data android:scheme="file" /> 

As stated in the comments, the accepted answer uses a lot of memory. While MediaScannerConnection doesn’t have a “deleteFile” method, just pass in the the old file path to the “scanFile” method once you’ve deleted the file. The media scanner will rescan and remove the media.

tested on N5. Android 4.4.

EDIT: Other have stated this doesn’t work on 4.2

new AsyncTask<Void, Void, Void>(){
        protected Void doInBackground(Void... params) {
            String filePath = recording.file.getAbsolutePath();
                    new String[]{filePath}, null, null);
            return null;

You can also delete the image from the Gallery by using:

getContentResolver().delete(imageUri, null, null);

Just make sure that ‘imageUri’ is the uri returned to you when you called insert.
