Settings.canDrawOverlays(context)在Android Oreo上返回false [英] Settings.canDrawOverlays(context) returns false on Android Oreo

问题描述

清单:

<uses-permission android:name="android.permission.SYSTEM_OVERLAY_WINDOW" />
<uses-permission android:name="android.permission.ACTION_MANAGE_OVERLAY_PERMISSION" />

代码activity.onCreate():

Code activity.onCreate():

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && BuildConfig.DEBUG) {
        if (!Settings.canDrawOverlays(this)) {
            Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
                    Uri.parse("package:" + getPackageName()));
            startActivityForResult(intent, OVERLAY_PERMISSION_REQ_CODE);
        }
    }

问题:即使已经授予了权限，Settings.canDrawOverlays(this)也会返回false.在将Pixel更新为Oreo之前没有发生.

Problem: Settings.canDrawOverlays(this) returns false even so the permission has been already granted. Hasn't happened before update Pixel to Oreo.

Android版本:8.0.0

Android version: 8.0.0

我尝试将构建工具更新为:26.0.1，将target和compileSdk更新为26. 它在第一次启动时有所帮助:切换后返回true，但是下次启动应用程序时，它将再次返回false.

I've tried to update build tools: to 26.0.1 and target and compileSdk to 26. It helped on the first launch :after toggling on it returns true, but next time I launch application it returns false again.
