android 5.0 创建多用户 双开多开应用（2）

上一讲 讲了如何创建一个user

android 5.0 创建多用户 双开多开应用（1）

为什么要创建User  例如window 系统创建了一个user 会在当前用户下进行操作，而android 多用户体系就像window系统

创建了一个user之后在当前user下进行操作，就可以再安装或者启动一个应用。

有了一个user 之后在这个user下创建一个工作空间，在工作空间下安装 启动apk 就可以双开了。

具体类操作：

    package android.app.admin;  

    import android.content.ComponentName;
    import android.content.Intent;
    import android.content.IntentFilter;
