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