Android How to use MediaScannerConnection scanFile

Or you can use following method:

private void scanFile(String path) {

        MediaScannerConnection.scanFile(MainActivity.this,
                new String[] { path }, null,
                new MediaScannerConnection.OnScanCompletedListener() {

                    public void onScanCompleted(String path, Uri uri) {
                        Log.i("TAG", "Finished scanning " + path);
                    }
                });
    }

Call file scan as:

scanFile(yourFile.getAbsolutePath());

I realized that perhaps you were looking for a solution what would work previous to api level 8, and I could not make sense of Mitch's answer. I solved it by building a class for scanning a single file:

import java.io.File;
import android.content.Context;
import android.media.MediaScannerConnection;
import android.media.MediaScannerConnection.MediaScannerConnectionClient;
import android.net.Uri;

public class SingleMediaScanner implements MediaScannerConnectionClient {

    private MediaScannerConnection mMs;
    private File mFile;

    public SingleMediaScanner(Context context, File f) {
        mFile = f;
        mMs = new MediaScannerConnection(context, this);
        mMs.connect();
    }

    @Override
    public void onMediaScannerConnected() {
        mMs.scanFile(mFile.getAbsolutePath(), null);
    }

    @Override
    public void onScanCompleted(String path, Uri uri) {
        mMs.disconnect();
    }

}

and you would use it like this to make the MediaScannerConnection scan a single file:

new SingleMediaScanner(this, file);

I was looking for the same thing and I found this in the ApiDemos, ExternalStorage. Solved all my problems as it scans a single file.

 MediaScannerConnection.scanFile(this,
          new String[] { file.toString() }, null,
          new MediaScannerConnection.OnScanCompletedListener() {
      public void onScanCompleted(String path, Uri uri) {
          Log.i("ExternalStorage", "Scanned " + path + ":");
          Log.i("ExternalStorage", "-> uri=" + uri);
      }
 });

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