权限

1、注册权限

<uses-permission android:name=”android.permission.SYSTEM_ALERT_WINDOW” />

2、动态申请权限

API19以后需要动态申请权限,API23以前默认是开放的,但是个别厂商自己定制了开启权限验证,比较坑爹,API23以后google提供的统一了跳转页面.

骚操作(建议还是官方提供的操作来)

19<=api<26 可以使用type = TYPE_TOAST 官方产生的漏洞,不需要静态注册也不需要动态申请权限.参考https://blog.csdn.net/u013651405/article/details/79350857测试结果,小米和vivo不在其中.

问题

permission denied for window type 2003

除了要注册权限和申请权限外,可能会遇到type不支持的情况,建议对8.0以上的系统使用如下类型.

<pre>if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
  type = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
} else {
  type = WindowManager.LayoutParams.TYPE_SYSTEM_ALERT;
}</pre>
