Android15 安装APK时监听且替换安装

有些特殊需求，需要监听安装的APK，当监听到这个APK安装的时候，替换掉它，安装已经预置的APK，修改如下：

1.在framework/base/services/core/java/com/android/server/pm/InstallingSession.java里面

修改：

这里是当检测到安装GMS相关的环境检测应用的时候，终止安装，发送自定广播安装自定义应用，替换当前检测应用。

2.安装应用

收到广播后可以使用Runtime.getRuntime().exec安装预置的应用

java 复制代码

public boolean silenceInstallApk( String path){
        try {
            Runtime.getRuntime().exec("pm install -r "+path);
            return true;
        } catch (Exception e) {
           return false;
        }
    }
