Bug：java.lang.NullPointerException: Attempt to invoke virtual method ‘void android.support.v4.app.FragmentActivity.runOnUiThread(java.lang.Runnable)‘ on a null object reference at me.chunyu.ChunyuDoctor.Modules.DoctorService.h.run(Unknown Source) at java.lang.Thread.run(Thread.java:818)
原因：http://stackoverflow.com/questions/23825549/nullpointerexception-on-getactivity-runonuithreadnew-runnable
I‘m almost sure that this is caused when the thread finish its work but the activity is no longer visible.You should check if the "getActivity()" call return null, and ...
getActivity()有可能為空白，需要提前判斷；位置：DocServiceBannerFragment；
if (getActivity() == null) return; getActivity().runOnUiThread(new Runnable() { @Override public void run() { _updateBanners(bannerItems, bannerImages); } });
即可，完成。
