android如何做到类似于微信那样后台服务不会被杀死？

问题描述

正在做一款锁屏应用。

做锁屏肯定用到了service，可是我发现每日手动点击自带的内存清理按钮的时候，我的那个service总是会被杀死。

而微信的后台服务却是一直正常的运行，不会被杀掉。

360的话也不会被杀死，但是360会重新启动。而且360的是两个后台服务，我猜有可能会相互作用的，杀死一个的时候另一个接收到广播把其重启。

尝试过用startForeground以及提高service优先级的方式，发现都不行，service都会被杀死。

反编译了一下微信的代码。

请大家帮忙想想办法吧。谢了

下面是微信的注册service：

代码如下：

解决方案1

android 系统杀程序，一个很重要的判断就是软件系统资源的占用情况。

解决方案2

mark一下，等待结果
