com.xvideostudio.videoeditor 这个应用发生无响应
1. 在system log里面搜索关键字，ANR in，定位到下面的地方
11-01 15:52:37.386071 1148 1273 I AnrManager: ANR in com.xvideostudio.videoeditor (com.xvideostudio.videoeditor/.activity.ConfigGifActivity), time=24740223
11-01 15:52:37.386071 1148 1273 I AnrManager: Reason: Input dispatching timed out (Waiting to send non-key event because the touched window has not finished processing certain input events that were delivered to it over 500.0ms ago. Wait queue length: 2. Wait queue head age: 10273.7ms.)
11-01 15:52:37.386071 1148 1273 I AnrManager: Load: 33.27 / 34.07 / 33.02

2.在event log里面搜索关键字，定位到如下地方
11-01 15:52:19.400932 1148 1273 I am_anr : [0,30828,com.xvideostudio.videoeditor,949534276,Input dispatching timed out (Waiting to send non-key event because the touched window has not finished processing certain input events that were delivered to it over 500.0ms ago. Wait queue length: 2. Wait queue head age: 10273.7ms.)]
3.导出 data/anr/目录，会记载发生anr时的信息

主线程在等待GLThreadManager对象被唤醒，在anr文件里面搜到GLThread
"GLThread 5127" prio=5 tid=21 Sleeping

结合上面的信息和代码得知，GLThread线程在等待FxRender的onDrawFrame执行完后才会对GLThreadManager对象进行唤醒。但是onDrawFrame方法一直执行不完，这部分逻辑是三方apk的逻辑，所以此问题为三方问题
