    copied!<p>I first try to create the SurfaceView with: </p> <pre><code>SurfaceView sv = new SurfaceView(context); // Get a surface surfaceHolder = sv.getHolder(); // tells Android that this surface will have its data constantly // replaced surfaceHolder.addCallback(this); surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE); LayoutParams params = new WindowManager.LayoutParams(WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY, WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH, PixelFormat.TRANSLUCENT); wm.addView(sv, params); </code></pre> <p>Then try to prepare recorder:</p> <pre><code>try { camera.unlock(); mediaRecorder = new MediaRecorder(); mediaRecorder.setCamera(camera); mediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER); mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA); mediaRecorder.setProfile(CamcorderProfile .get(CamcorderProfile.QUALITY_HIGH)); mediaRecorder.setOutputFile(getOutputMediaFile(MEDIA_TYPE_VIDEO, appName).toString()); mediaRecorder.setPreviewDisplay(surfaceHolder.getSurface()); mediaRecorder.prepare(); } catch (IllegalStateException e) { releaseMediaRecorder(); Log.d(TAG, "IllegalStateException preparing MediaRecorder: " + e.getMessage()); return false; } catch (IOException e) { releaseMediaRecorder(); Log.d(TAG, "IOException preparing MediaRecorder: " + e.getMessage()); return false; } return true; </code></pre> <p>But I get an error "Application lost the surface" despite that I can see that preview is working. Why is that?</p>
