报错原因：setSettingsDetailsTitle方法中mSettingsDetailsTitle为null导致crash

【根本原因】SettingsHomepageActivity中的onCreate中的surper.onCreate方法经过一系列回调后调到TopLevelSettings.onPreferenceStartFragment然后调用SettingsHomepageActivity.changeSettingsDetailsFragment方法，此时SettingsHomepageActivity本就没有初始化成功资源还没有初始化。
【解决方案】更改TopLevelSettings.onPreferenceStartFragment里的回调逻辑，做延时机制
【下一步动作】这个是做feature时，衍生出来的bug，需要转给相关同事处理
