Please see the code below and if you have any solution for it than it will be helpful to me.

public class SimpleCamera extends Activity implements SurfaceHolder.Callback
{
private Camera camera;
private boolean isPreviewRunning = false;
private SimpleDateFormat timeStampFormat = new SimpleDateFormat("yyyyMMddHHmmssSS");
private SurfaceView surfaceView;
private SurfaceHolder surfaceHolder;
private Uri targetResource = Media.EXTERNAL_CONTENT_URI;
public void onCreate(Bundle icicle)
{
super.onCreate(icicle);
Window window = getWindow();
window.addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
window.addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().setFormat(PixelFormat.TRANSLUCENT);
setContentView(R.layout.main);
surfaceView = (SurfaceView)findViewById(R.id.surface);
surfaceHolder = surfaceView.getHolder();
surfaceHolder.getSurface();
// Surface.setOrientation(Display.DEFAULT_DISPLAY,Surface.ROTATION_180); //didn't work at all
surfaceHolder.addCallback(this);
surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
}
public boolean onCreateOptionsMenu(android.view.Menu menu) {
MenuItem item = menu.add(0, 0, 0, "View Pictures");
item.setOnMenuItemClickListener(new MenuItem.OnMenuItemClickListener() {
public boolean onMenuItemClick(MenuItem item) {
Intent intent = new Intent(Intent.ACTION_VIEW, targetResource);
startActivity(intent);
return true;
}
});
return true;
}
protected void onRestoreInstanceState(Bundle savedInstanceState)
{
super.onRestoreInstanceState(savedInstanceState);
}
Camera.PictureCallback mPictureCallbackRaw = new Camera.PictureCallback() {
public void onPictureTaken(byte[] data, Camera c) {
camera.startPreview();
}
};
Camera.ShutterCallback mShutterCallback = new Camera.ShutterCallback() {
public void onShutter() {
}
};
public boolean onKeyDown(int keyCode, KeyEvent event)
{
ImageCaptureCallback camDemo = null;
if(keyCode == KeyEvent.KEYCODE_DPAD_CENTER) {
try {
String filename = timeStampFormat.format(new Date());
ContentValues values = new ContentValues();
values.put(Media.TITLE, filename);
values.put(Media.DESCRIPTION, "Image from Android Emulator");
Uri uri = getContentResolver().insert(Media.EXTERNAL_CONTENT_URI, values);
camDemo = new ImageCaptureCallback( getContentResolver().openOutputStream(uri));
} catch(Exception ex ){
}
}
if (keyCode == KeyEvent.KEYCODE_BACK) {
return super.onKeyDown(keyCode, event);
}
if (keyCode == KeyEvent.KEYCODE_DPAD_CENTER) {
camera.takePicture(mShutterCallback, mPictureCallbackRaw, camDemo);
return true;
}
return false;
}
protected void onResume()
{
Log.e(getClass().getSimpleName(), "onResume");
super.onResume();
}
protected void onSaveInstanceState(Bundle outState)
{
super.onSaveInstanceState(outState);
}
protected void onStop()
{
super.onStop();
}
public void surfaceChanged(SurfaceHolder holder, int format, int w, int h)
{
if (isPreviewRunning) {
camera.stopPreview();
}
Camera.Parameters p = camera.getParameters();
p.setPreviewSize(w,h);
//p.set("rotation","90"); // it didn't work
//P.setRotation(90); // only work in 2.0 or later SDK but i am using 1.5
camera.setParameters(p);
try {
camera.setPreviewDisplay(holder);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
camera.startPreview();
isPreviewRunning = true;
}
public void surfaceCreated(SurfaceHolder holder)
{
camera = Camera.open();
}
public void surfaceDestroyed(SurfaceHolder holder)
{
camera.stopPreview();
isPreviewRunning = false;
camera.release();
}
}
any help will be appreciated..
