Question

I am having an issue with the camera class on android 2.2 tablet. The problem is that when activating the camera preview, I see static as seen below:

The static is seen below, even when I operate the camera class on full screen.

My code for the camera is below:

public class OoohaPrototypeActivity extends Activity {
/** Called when the activity is first created. */
private CameraPreview mPreview;
Camera mCamera;
int numberOfCameras;
int cameraCurrentlyLocked;

// The first rear facing camera
int defaultCameraId;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);


    mPreview = new CameraPreview(this);
     setContentView(mPreview);
}

I face the same issue even after restarting the tablet. The tablet’s normal camera app preview works fine though. The CameraPreview class is the same one seen in

This is an old thread, but I might be of assistance, does your tablet has a front facing camera only ? the camera.open(); will return null on if you’re tablet does not have a rear facing camera.

Therefore what is probably best is to check for a null, and open the default camera using something like

Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);

and handle the result of this call
