我的一个测试app，会进行：
-音乐播放，一直进行
-视频播放/图片显示：间歇性进行
-CPU高负载运行：一直进行
总计运行4小时。
总计跑了100次，大约5次会出现被系统kill掉的情况。
看log是因为：系统要把广播（android.intent.action.BATTERY_CHANGED）发送给应用时却失败了，从而导致应用被系统杀掉。
其它背景：
-这个应用通过shareUserId的方式与“android.uid.system”共享user ID；
-应用的安装包即apk文件在手机的system/app目录下。
-应用的pid是8047。
不知道什么原因会引起系统发广播给我的应用时，出现了抛出DeadObjectException的失败的情况？
相关log片段如下：
