“与所有者的长时间监视器争用”警告

我明白了警告信息自从我看到这条消息后，我也开始看到Google Play 服务没有响应弹出窗口和它关闭我的申请一段时间后。我查看过类似的问题，但找不到原因。

以下是我的处理程序线程使用示例。我不知道该怎么做才能避免这个问题。

@Override
public void find(Func1<RealmQuery<Artist>, RealmQuery<Artist>> query,
                 Action1<Result<List<Artist>>> onResult) {
    if (query != null) {


        handlerThread = new HandlerThread("MyHandlerThreadArtist");
        handlerThread.start();
        looper = handlerThread.getLooper();

        Handler handler = new Handler(looper);

        handler.post(new Runnable(){
            @Override
            public void run() {
                Timber.log(Log.DEBUG, "ARTISTDAOIMPL", "find Thread.currentThread().getName() " + Thread.currentThread().getName());

                mDatabase.findRealmObject(Artist.class, query,
                        result -> onResult.call(
                                Result.getData(Arrays.asList(result.data.toArray(new Artist[]{})))
                        ), err -> onResult.call(Result.getError(err))
                );
            }
        });

    }

I use fabric得到崩溃报告。不确定是否与此相关。 这部分内容来自于traces.txt显示有关信息的文件答案事件处理程序1我认为这会有帮助。

这是另一个类似的警告：

这部分也来自traces.txt文件关于"Queue":

首先，它显示的是特定处理程序线程名称我在应用程序中使用的。目前它不显示它们，但会打印这些内容。

我需要了解这是否是一个大问题以及如何解决它们。

Thanks.
