Android 应用程序因 QMI_LOC_EVENT_POSITION_REPORT_IND_V02 崩溃

Question

我正在 LG G Pad 8.3 和 Android 4.4.2 上运行应用程序。该应用程序使用 OpenCV 处理视频输入并使用 GPS 信息。启动后 20-30 秒，应用程序崩溃且没有消息。调试输出粘贴在下面。似乎这一行： E/LocSvc_ApiV02(865): I/

Answer 1

正如here 的回答，尝试在 onCameraFrame() 中手动调用垃圾收集器：

System.gc();

这解决了我的问题，即应用程序在一分钟左右后关闭而没有任何错误。
