当mediaPlayer.isPlaying()时，此时finsh当前activity时，由于mediaPlayer无法及时自动回收，当前activity会出现临时的内存泄漏，不影响正常使用，下版本将会修复。

然而好像并不只是这样的，搜了下发现貌似此问题只出现在Android7.1.1 上， it seems like an SDK leak，参考：https://github.com/square/leakcanary/issues/721 ，无法完全修复。补充：以及Android7.1.2

I think the leak you referenced is a different issue. If you look at the stack trace for the LeakCanary issue, it has only Android library classes other than the leaked activity itself. The activity reference causing this leak looks like it's coming from the implicit reference that the OnCompletionListener holds to the CaptureFragment class, and the leak may be resolvable by making your OnCompletionListener class a static inner class of your CaptureFragment class and storing a weak reference to your CaptureFragment in its constructor. Something like:

public class CaptureFragment ... {
    ...
    static class CaptureFragmentOnCompletionListener implements OnCompletionListener {
        WeakReferenced<CaptureFragment> weakCaptureFragment;
        public OnCompletionListener(CaptureFragment captureFragment) {
             weakCaptureFragment = new WeakReference<>(captureFragment);
        }

        @Override
        public void onCompletion(MediaPlayer mediaPlayer) {
             CaptureFragment captureFragment  = weakCaptureFragment.get();
             if (captureFragment == null)
                 return;
             ...
        }
    }
    private void setOnCompletionListener(MediaPlayer mediaPlayer) {
        mediaPlayer.setOnCompletionListener(new CaptureFragmentOnCompletionListener(this));
    }
}

I reproduced this leak on my phones. this is the detail logs:

there are many ways to fix,And i had fixed it in CaptureActivity by :

        @Override
        public void onDestroy() {
            super.onDestroy();
            inactivityTimer.shutdown();
            if (mediaPlayer != null) {
                mediaPlayer.stop();
                mediaPlayer.release();
                mediaPlayer = null;
            }
        }

pealse update to V1.0.6

I hope this can hlep you .
