Title Body

So I've read over the Camera API and couldn't find anything on this. I'm using the Camera to grab frames and it works perfectly, until I try to release the camera. I replicated the error in one sequence of calls: camera = Camera.open(); camera.setPreviewDisplay(getHolder()); Parameters params = camera.getParameters(); List<Size> ls = params.getSupportedPreviewSizes(); Size size = ls.get(1); this.width = size.width; this.height = size.height; params.setPreviewSize(size.width, size.height); camera.setParameters(params); camera.setDisplayOrientation(90); camera.setPreviewCallback(this); camera.startPreview(); camera.stopPreview(); camera.release(); The error I get is 03-22 13:31:42.592: E/AndroidRuntime(14152): java.lang.RuntimeException: Method called after release() 03-22 13:31:42.592: E/AndroidRuntime(14152): at android.hardware.Camera.setHasPreviewCallback(Native Method) 03-22 13:31:42.592: E/AndroidRuntime(14152): at android.hardware.Camera.access$600(Camera.java:114) 03-22 13:31:42.592: E/AndroidRuntime(14152): at android.hardware.Camera$EventHandler.handleMessage(Camera.java:545) 03-22 13:31:42.592: E/AndroidRuntime(14152): at android.os.Handler.dispatchMessage(Handler.java:99) 03-22 13:31:42.592: E/AndroidRuntime(14152): at android.os.Looper.loop(Looper.java:130) 03-22 13:31:42.592: E/AndroidRuntime(14152): at android.app.ActivityThread.main(ActivityThread.java:3684) 03-22 13:31:42.592: E/AndroidRuntime(14152): at java.lang.reflect.Method.invokeNative(Native Method) 03-22 13:31:42.592: E/AndroidRuntime(14152): at java.lang.reflect.Method.invoke(Method.java:507) 03-22 13:31:42.592: E/AndroidRuntime(14152): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:845) 03-22 13:31:42.592: E/AndroidRuntime(14152): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:603) 03-22 13:31:42.592: E/AndroidRuntime(14152): at dalvik.system.NativeStart.main
