关于Android 8.0java.lang.SecurityException: Permission Denial错误的解决方法

背景

当我在Android 7.0及以下手机运行启动页，进行Activity跳转的时候，完美跳转到对应的目标Activity。

但当在Android 8.0及以上手机进行Activity跳转时，会爆如下错误：

 java.lang.SecurityException: Permission Denial: null asks to run as user 450 but is calling from user 0; this requires android.permission.INTERACT_ACROSS_USERS_FULL or android.permission.INTERACT_ACROSS_USERS

常规解决方法

按StackOverFlow上面的方法增加权限

<permission android:name="android.permission.INTERACT_ACROSS_USERS_FULL" android:protectionLevel="signature"/>

发现并没有什么作用！！！！

我的解决方法

解决历程

经过几个小时的排查发现，当我的目标Activity继承AppCompatActivity时 程序没有问题。当目标Activity继承我自己的BaseActivity(我这个BaseActivity最终也会继承AppCompatActivity)时就会出现问题。

完美解决方法

我自己的BaseActivity里面有一个用于获取用户ID的public void getUserId()方法，就是这货。

当你把这个方法改过名字（例如：getLocalUserId()）或者修改该**getUserId()为private时，程序完美运行。

因此，可以知道这个getUserId()*是在原基类里面有实现的。

最后，希望我的方法能帮助到各位小伙伴。Thx~
