surfaceview

I want to use the switch camera function. Currently I have Developed a Camera Object That working fine for back-camera but not working for front-camera. And I am unable to find a solution for switching between front and back cameras. Here is My Code..! public class MyCamera extends Activity implements SurfaceHolder.Callback, Camera.ShutterCallback, Camera.PictureCallback { Camera mCamera; SurfaceView mPreview; String filePath; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.camera_preview); mPreview = (SurfaceView)

I'm currently getting to grips with Android, playing around with the Lunar Lander sample. I've found that if you navigate away from the app (eg, hit the call button) it will destroy the underlying surface (calling surfaceDestroyed ). Navigating back (which will trigger onWindowVisibilityChanged ) the app will crash, as it will try to draw to the surface without recreating it. Is there some code I can put in onWindowVisibilityChanged (or anywhere else) that will regenerate the SurfaceView's underlying surface and resume execution nicely? It feels like this should be a simple function call but I

I noticed that my application's view returns 0 for getWidth() and getHeight() after onMeasure() has already been called. This only happens on a handful of devices, for most android devices the following code works fine. My checkViewAndLoad() function loads a scaled bitmap depending on the size of the view. @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(widthMeasureSpec, heightMeasureSpec); Log.d("widthMeasureSpec", Integer.toString(MeasureSpec.getSize(widthMeasureSpec))); Log.d("heightMeasureSpec", Integer.toString(MeasureSpec.getSize

I use the https://github.com/googlesamples/android-Camera2Basic , but try to modify it in a way that I could get access to each frame before it is drawn on the surfaceview. I understood, I should add additional surface (ImageReader.getSurface()), and read the frame from it in this callback: private final ImageReader.OnImageAvailableListener mOnImageAvailableListener = new ImageReader.OnImageAvailableListener() { @Override public void onImageAvailable(ImageReader reader) { Log.d("Img", "onImageAvailable"); mBackgroundHandler.post(new ImageSaver(reader.acquireNextImage(), mFile)); } }; The

I'm have a game that's uses SurfaceView implementation to display the objects. I have a thread which draws the SurfaceView time-to-time to the screen. The game is running completely. Unfortunately, it needed to have a pause function whenever the game is interrupted. Well, I know that I need to manipulate onResume and onPause . But I can't get it right. The error points me back to surfaceCreated where I start the thread telling me that the thread has started already. I tried using the resume and suspend on the onResume and onPause respectively but nothing changed. How can I achieve this? I have

Whenever I run the cam_thread I get the error "app passed NULL surface". This code supposedly works on the HTC Incredible 1. I've reconfigured it slightly to run on a droid x. However I still get this error. public class Android_Activity extends Activity { Main_thread simulator; ToggleButton togglebutton; EditText ip_text; SensorManager sm = null; SurfaceView view; Sensors_thread the_sensors=null; String IP_address; Android_Activity the_app; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); view = new SurfaceView

I am trying to develop a BarcodeReader using Google play services, and i would like to get a camera surface background like Zxing sample. Actually I view with a black transparent background and a white Rect Canvas, and i would like this Rect to be transparent, so my question is if can change the view background without this Rect bounds. This is my Custom View where i draw some lines public class MyView extends View { private Paint paint; private Path path; private int width, height; Canvas canvas; private Rect rectangle; public MyView(Context context) { super(context); init(); } public MyView
