Android原生JobSchedulerContext内存泄漏导致设备重启的现象

news 来源：原创 2024/9/21 11:12:43

一、现象：原生JobSchedulerContext内存泄漏占比

JobServiceContext内存泄露导致ServiceDispatcher也跟着一起内存堆积

二、现象日志：

内存泄漏的日志关键信息：ActivityManager: Unbind failed: could not find connection for android.app.LoadedApk$ServiceDispatcher$InnerConnection@492fb1，内存堆积现象

Unbind failed 现象：
// main日志
