Answer 1

1.Use below permissions in manifest file and always put permissions above Application tag.

2.Use Unlock while camera used by other service like MediaRecorder.

camera.unlock();
recorder.setCamera(camera);

2.Released camera properly, I prefer to use lock so become safely accessible for other application and second time use (In case if we reopen).

if (camera != null) {
        camera.lock();
        camera.stopPreview();
        camera.release();
        camera = null;
    }
