    <p>Ok. So here is the solution:</p> <p>I am not adding any try catch. This is simply for the capturing the image and storing it into the sdcard.</p> <pre><code>public class VideoServer extends Activity implements SurfaceHolder.Callback { TextView testView; Camera camera; SurfaceView surfaceView; SurfaceHolder surfaceHolder; PictureCallback rawCallback; ShutterCallback shutterCallback; PictureCallback jpegCallback; private final String tag = "VideoServer"; Button start, stop, capture; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); start = (Button)findViewById(R.id.btn_start); start.setOnClickListener(new Button.OnClickListener() { public void onClick(View arg0) { start_camera(); } }); stop = (Button)findViewById(R.id.btn_stop); capture = (Button) findViewById(R.id.capture); stop.setOnClickListener(new Button.OnClickListener() { public void onClick(View arg0) { stop_camera(); } }); capture.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub captureImage(); } }); surfaceView = (SurfaceView)findViewById(R.id.surfaceView1); surfaceHolder = surfaceView.getHolder(); surfaceHolder.addCallback(this); surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); rawCallback = new PictureCallback() { public void onPictureTaken(byte[] data, Camera camera) { Log.d("Log", "onPictureTaken - raw"); } }; /** Handles data for jpeg picture */ shutterCallback = new ShutterCallback() { public void onShutter() { Log.i("Log", "onShutter'd"); } }; jpegCallback = new PictureCallback() { public void onPictureTaken(byte[] data, Camera camera) { FileOutputStream outStream = null; try { outStream = new FileOutputStream(String.format( "/sdcard/%d.jpg", System.currentTimeMillis())); outStream.write(data); outStream.close(); Log.d("Log", "onPictureTaken - wrote bytes: " + data.length); } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } finally { } Log.d("Log", "onPictureTaken - jpeg"); } }; } private void captureImage() { // TODO Auto-generated method stub camera.takePicture(shutterCallback, rawCallback, jpegCallback); } private void start_camera() { try{ camera = Camera.open(); }catch(RuntimeException e){ Log.e(tag, "init_camera: " + e); return; } Camera.Parameters param; param = camera.getParameters(); //modify parameter param.setPreviewFrameRate(20); param.setPreviewSize(176, 144); camera.setParameters(param); try { camera.setPreviewDisplay(surfaceHolder); camera.startPreview(); //camera.takePicture(shutter, raw, jpeg) } catch (Exception e) { Log.e(tag, "init_camera: " + e); return; } } private void stop_camera() { camera.stopPreview(); camera.release(); } public void surfaceChanged(SurfaceHolder arg0, int arg1, int arg2, int arg3) { // TODO Auto-generated method stub } public void surfaceCreated(SurfaceHolder holder) { // TODO Auto-generated method stub } public void surfaceDestroyed(SurfaceHolder holder) { // TODO Auto-generated method stub } } </code></pre> <p>Don't press <strong>caputure</strong> button before the <strong>start</strong>,because I didn't checked it. I just wanted to show you that how to capture and store image into the <strong>sdcard</strong>.</p>

    2. COYour solution is perfect. But one more question, how can I get the captured image as bitmap to make further effect?

    3. COfor that you have to take the captured image from the sdcard using this. Bitmap bitmap = BitmapFactory.decodeFile("/path/images/imageName.jpg"); And you can do further operation onto the bitmap

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.

SQuiL has stopped working due to an internal error.

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