java - 窗口类型 2002 和 2038 的权限被拒绝

Question

我正在显示一个服务过度窗口，并且它与我的大多数用户都可以正常工作，但是我在 Crashlytics 上发现了这些错误

旧设备（Android 7 及更低版本）

Fatal Exception: java.lang.RuntimeException: Unable to create service com.app.name.mainService: android.view.WindowManager$BadTokenException: Unable to add window android.view.ViewRootImpl$W@43108e0 -- permission denied for window type 2002

较新的设备（尤其是 Galaxy S8 Android 9.0）

Fatal Exception: java.lang.RuntimeException: Unable to create service com.app.name.mainService: android.view.WindowManager$BadTokenException: Unable to add window android.view.ViewRootImpl$W@df3ca8f -- permission denied for window type 2038

我正在使用的代码是

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
            params = new WindowManager.LayoutParams(
                    WindowManager.LayoutParams.MATCH_PARENT,
                    WindowManager.LayoutParams.MATCH_PARENT,
                    WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY,

                    WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN |
                            WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE |
                            WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
                            WindowManager.LayoutParams.FLAG_SPLIT_TOUCH |
                            WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM,
                    PixelFormat.TRANSLUCENT);
        } else {
            params = new WindowManager.LayoutParams(
                    WindowManager.LayoutParams.MATCH_PARENT,
                    WindowManager.LayoutParams.MATCH_PARENT,
                    WindowManager.LayoutParams.TYPE_PHONE,

                    WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN |
                            WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE |
                            WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
                            WindowManager.LayoutParams.FLAG_SPLIT_TOUCH |
                            WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM,
                    PixelFormat.TRANSLUCENT);
        }

        mWindowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
        if (mWindowManager != null) {
            mWindowManager.addView(serviceRootView, params);
        }

我还确保已授予 Draw 权限并且清单文件具有以下权限

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

我搜索了很多其他问题，都提出了上述解决方案，但由于崩溃仍然发生，所以没有帮助！
