Why camera not work in Android 5?

Question

In android 2.3, 4, 4.1, 4.2, 4.3, 4.4 works correctly

I've this function with android 2.3 api:

public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) {
   // 1º Si se esta viendo preview, se detiene
   if (mPreviewRunning) {
      mCamera.stopPreview();
   }
   // 2º Se setean los nuevos parametros de la camara
   Camera.Parameters p = mCamera.getParameters();
   p.setPreviewSize(w, h);
   mCamera.setParameters(p);

   // 3º Volvemos a mostrar el preview
   try {
      mCamera.setPreviewDisplay(holder);
   } catch (IOException e) {
      e.printStackTrace();
      Toast.makeText(ctxt, "Error refreshing camera", Toast.LENGTH_LONG)
            .show();
   }

   mCamera.startPreview();
   mPreviewRunning = true;
}

The app crash in line, return

error: W/System.err: java.lang.RuntimeException: Fail to connect to camera service

mCamera.setParameters(p);

after return this:

W/System.err: java.io.IOException: open failed: ENOENT (No such file or directory)

This is my manifest for my two apps:

    package="com.foca.deboSancion"

Answer 1

Well mCamera.setParameters(p); is not lollypop(android 5.0) api issue, its device specific. Most of the devices behaviour with the camera parameters are is final, I mean ur cannot change it, if you try it will crash. Easy possible solution use of try catch, advanced is use reflection (suggestion : dont go for this)
