Why video of camera interference in android 2.3?

public static Camera getCameraInstance() {
        Camera c = null;
        try {
            c = Camera.open(); // attempt to get a Camera instance
            if (c != null) {
                Camera.Parameters params = c.getParameters();
                params.setRotation(90);
                c.setParameters(params);
            }
        } catch (Exception e) {
            Log.d("DEBUG", "Camera did not open");
            // Camera is not available (in use or does not exist)

        }
        return c; // returns null if camera is unavailable
    }

onCreate:

// Create an instance of Camera
            mCamera = getCameraInstance();
mPreview = new CameraPreview(this, mCamera);
preview = (FrameLayout) findViewById(R.id.camera_preview);
            preview.addView(mPreview);

CameraPreview:

public CameraPreview(Context context, Camera camera) {
        super(context);
        mCamera = camera;

        // Install a SurfaceHolder.Callback so we get notified when the
        // underlying surface is created and destroyed.
        mHolder = getHolder();
        mHolder.addCallback(this);
        // deprecated setting, but required on Android versions prior to 3.0
        mHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);

This is just one potential problem. From the docs:

// deprecated setting, but required on Android versions prior to 3.0
        mHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);

You are not implementing the Camera API correctly. Please look at the Android Guide on how to create a camera app.
