如果您甚至在请求权限之前就需要权限，也许您应该得出这样的结论：您的代码没有很好的体系结构。

只需绕过该代码，直到您可以在授予权限时重新启动它。

在您的问题中，您似乎希望在创建应用程序时发送设备ID。除非你得到许可，否则不要发送它。

if (checkPermission(...) == GRANTED) {
    PropertyManager mgr = new PropertyManager(this);
    mActivityLogger = new ActivityLogger(mgr.getSingularProperty(PropertyManager.DEVICE_ID_PROPERTY));
} else {
    mActivityLogger = new ActivityLogger();
    // Or even disable that logger altogether
}
