Question

我在LG G Pad 8.3上使用Android 4.4.2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，应用程序崩溃而没有消息。调试输出粘贴在下面。看来这行： E / LocSvc_ApiV02（865）：I /＆lt; --- void globalEventCb（locClientHandleType，uint32_t，locClientEventIndUnionType，void *）第81行QMI_LOC_EVENT_POSITION_REPORT_IND_V02 是重要的一个，其次是＆＃34;位置听众死了＃34;不久之后。我还没有找到足够的信息。同样有趣的是，在我的三星Galaxy S3 mini（Android 4.2.2）上，相同的应用程序没有任何问题。

Answer 1

回答here时，尝试在onCameraFrame（）中手动调用垃圾收集器：

System.gc();

这解决了我在一分钟左右后应用程序关闭而没有任何错误的问题。

Android应用与QMI_LOC_EVENT_POSITION_REPORT_IND_V02崩溃
