android - fragment 的 onCreateView 中的 inflater.inflate 抛出异常

Question

Fragment 中的以下几行引发异常，我无法找到其根本原因。

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.fragment_player_pane, container, false);
    RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) rootView.getLayoutParams();

    // set width height
    params.height = (getArguments().getInt(HEIGHT));
    params.width = (getArguments().getInt(WIDTH));

    fragmentHeight = (getArguments().getInt(HEIGHT));
    fragmentWidth = (getArguments().getInt(WIDTH));

    // substitute parameters for left,top, right, bottom, (All 4 not necessary)
    params.setMargins((getArguments().getInt(LEFT_MARGIN)),
            (getArguments().getInt(TOP_MARGIN)),
            (getArguments().getInt(RIGHT_MARGIN)),
            (getArguments().getInt(BOTTOM_MARGIN)));

    youTubePlayerNecessary = getArguments().getBoolean(REQUIRE_YOUTUBE);
    rotate = getArguments().getBoolean(REQUIRE_ROTATION);
    muteAudio = getArguments().getBoolean(MUTE_AUDIO);

    rootView.setLayoutParams(params);

    return rootView;
}

异常(exception):

我目前正在 Debug模式下运行应用程序以检查所有可能的内存泄漏。

if (BuildConfig.DEBUG) {
        StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()
                .detectAll()
                .penaltyLog()
                .penaltyDeath()
                .build());
    }

list 文件中的所有标签也已正确关闭。我无法弄清楚哪个资源在没有被处理的情况下处于打开状态。我该如何解决这个问题？

附言我提到了thread在问这个问题之前，这是一个非常笼统的问题，没有为我提供新的必要见解。这个问题与上面提到的细节非常具体，我在这里寻求帮助以找出导致泄漏的资源..

有人在这里提出了一个问题:https://code.google.com/p/android/issues/detail?id=226751

我一直遇到同样的问题，看起来它是 API < 25 中的错误。在 API 25 的模拟器中尝试你的程序，看看它是否有效。如果它在那里工作，那么它很可能是同一个问题，在能够解决问题之前你运气不好。
