The correct approach is to use MediaScannerConnection.scanFile(). See this answer with more details.

In short:

1. Instantiate the MediaScannerConnection with a callback.
2. Connect to it using connect().
3. In the onMediaScannerConnected() callback, invoke scanFile(path, mimeType) to have the media scanner scan it. Note that the path is absolute and the mime type is optional (may be null).
4. When you're done, disconnect the MediaScannerConnection, for instance when the onScanCompleted() callback is executed.
