    <p>I am having some trouble with saving an image from r.drawable.image1 to the phone's SD Card in a Pictures Folder, then sending a broadcast to the MediaScanner to refresh the folders so that the image appears in the gallery on the phone.</p> <p>I beleive the solution is something to do with this</p> <pre><code>sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://"+ Environment.getExternalStorageDirectory()))); </code></pre> <p>The problem now is the image does not save to sd and I do not know where to put the above code for the media scanner as the code below does nothing now after me fiddling with it for the last 3 days. Please Help...</p> <pre><code>import java.io.ByteArrayOutputStream; import java.io.File; import java.io.FileOutputStream; import java.io.IOException; import java.io.OutputStream; import android.net.Uri; import android.app.Activity; import android.graphics.Bitmap; import android.graphics.BitmapFactory; import android.widget.Button; import android.widget.Toast; import android.media.MediaScannerConnection; import android.os.Bundle; import android.os.Environment; public class MainScreen extends Activity { private Button btnDownload; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); btnDownload=(Button)findViewById(R.id.SaveButton1); btnDownload.setOnClickListener( new Button.OnClickListener() { @Override public void onClick(View v) { String newPicture = saveToSDCard(R.drawable.image1, "image1.jpg"); startMediaScanner(newPicture); } } ); } private String saveToSDCard(int resourceID, String finalName) { StringBuffer createdFile = new StringBuffer(); Bitmap resourceImage = BitmapFactory.decodeResource(this.getResources(), resourceID); File externalStorageFile = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), finalName); ByteArrayOutputStream bytes = new ByteArrayOutputStream(); resourceImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes); byte b[] = bytes.toByteArray(); try { externalStorageFile.createNewFile(); OutputStream filoutputStream = new FileOutputStream(externalStorageFile); filoutputStream.write(b); filoutputStream.flush(); filoutputStream.close(); createdFile.append(externalStorageFile.getAbsolutePath()); } catch (IOException e) { } return createdFile.toString(); } private void startMediaScanner(String fileName) { MediaScannerConnection.scanFile(this, new String[] { fileName }, null, new MediaScannerConnection.OnScanCompletedListener() { public void onScanCompleted(String path, Uri uri) { Toast.makeText(MainScreen.this, "Media scan Completed", Toast.LENGTH_SHORT).show(); } }); } } </code></pre>

    1. COI have updated my original answer (http://stackoverflow.com/questions/4509877/android-dev-help-saving-an-image-from-res-raw-or-asset-folder-to-the-sd-card/4512973#4512973) I gave to you, so now it works correctly. I tried it on my phone. It resolves issue with MediaScanner you were facing with.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
