android - Phonegap应用程序在背景中死亡，同时收集位置

我有一个内置在PhoneGap中的应用，可以使用navigator.geolocation次来跟踪移动设备的坐标。用户可以控制开始跟踪以及结束跟踪。该应用程序的构建是为了在后台接收坐标更新。该应用程序适用于Android和iOS设备。

Android版本似乎在后台崩溃时容易崩溃。在一些手机上它确实没问题，但是在很多手机上，应用程序只会在它应该在后台收集坐标数据时死掉。我在下面发布了一个LogCat日志。在CCWalkerActivity经理调用“不再需要”之后不久Activity就会出现WIN DEATH（两者都在下面加粗）。但是，我无法确定为什么会发生这种情况以及为什么会这么频繁发生。

这是Phonegap的问题吗？创建一个可以使进程成为前台服务（使用startForeground()）的插件是否有益？
