android.view.WindowManager $ BadTokenException:无法添加窗口android.view.ViewRootImpl$W@c745883-权限被拒绝 [英] android.view.WindowManager$BadTokenException: Unable to add window android.view.ViewRootImpl$W@c745883 - permission denied

问题描述

这是我的堆栈跟踪:

我找到了关于TYPE_SYSTEM_ERROR在Android Oreo(8)中已被弃用的答案，因此我实现了以下同样发现的方法:

I found an answer about TYPE_SYSTEM_ERROR being deprecated in Android Oreo (8) so I implemented the following method that I also found:

public void fixAndroid() {
    WindowManager.LayoutParams params;
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
      params = new WindowManager.LayoutParams(
              WindowManager.LayoutParams.MATCH_PARENT,
              WindowManager.LayoutParams.MATCH_PARENT,
              WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY,
              WindowManager.LayoutParams.FLAG_FULLSCREEN,
              PixelFormat.TRANSLUCENT);
    } else {
      params = new WindowManager.LayoutParams(
              WindowManager.LayoutParams.MATCH_PARENT,
              WindowManager.LayoutParams.MATCH_PARENT,
              WindowManager.LayoutParams.TYPE_SYSTEM_ERROR,
              WindowManager.LayoutParams.FLAG_FULLSCREEN,
              PixelFormat.TRANSLUCENT);
    }
  }

在我的onCreate()方法中，我拥有:

Inside of my onCreate() method I have:

  @Override
  public void onCreate (Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // Checking permissions on init
    fixAndroid();
  }

我仍然会收到错误消息.

I still get the error.

我正在使用Expo SDK 21，React Native 0.48.该应用程序已分离到ExpoKit.

I am using Expo SDK 21, React Native 0.48. The application has been detached to ExpoKit.

每次更改后，我都会清理项目，然后通过Android Studio在模拟器上运行它.

After each change I clean my project and then run it on an Emulator through Android Studio.

我正在Nexus 5X模拟器上运行此程序，并在API 27上运行.

I am running this on a Nexus 5X emulator, running on API 27.

推荐答案

TYPE_SYSTEM_ALERT

对于非系统应用，此常量在API级别26中已弃用.使用TYPE_APPLICATION_OVERLAY代替.

This constant was deprecated in API level 26. for non-system apps. Use TYPE_APPLICATION_OVERLAY instead.
