Android 应用程序崩溃并显示 QMI_LOC_EVENT_POSITION_REPORT_IND_V02

Question

我正在运行 Android 4.4.2 的 LG G Pad 8.3 上的应用程序。该应用程序使用 OpenCV 处理视频输入，还使用 ​​GPS 信息。启动后 20-30 秒，应用程序崩溃且没有任何消息。调试输出粘贴在下面。似乎这一行: E/LocSvc_ApiV02(865):I/<---无效globalEventCb(locClientHandleType，uint32_t，locClientEventIndUnionType，void *)第81行QMI_LOC_EVENT_POSITION_REPORT_IND_V02是最重要的，紧接着是“位置监听器死亡”。我无法找到有关这些的足够信息。另外有趣的是，在我的三星 Galaxy S3 mini(Android 4.2.2)上，相同的应用程序运行没有任何问题。

Answer 1

已回答here ，尝试在 onCameraFrame() 中手动调用垃圾收集器，如下所示:

System.gc();

这解决了我的问题，应用程序在一分钟左右后关闭，没有任何错误。
