弹窗权限

需要适配对话框的类型，否则对话框无法在广播接收器里弹出

        Window window = dialog.getWindow();
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            window.setType(WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY);
        } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            window.setType(WindowManager.LayoutParams.TYPE_PHONE);
        } else {
            window.setType(WindowManager.LayoutParams.TYPE_TOAST);
        }

弹窗权限申请

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {
            if (!Settings.canDrawOverlays(this)) {
            Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION);
            intent.setData(Uri.parse("package:" + getPackageName()));
            startActivityForResult(intent, 2003);
            }
        }
