Bug: runOnUiThread

本文地址: http://blog.csdn.net/caroline_wendy

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：

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()有可能为空，需要提前判断；

位置：DocServiceBannerFragment；

                if (getActivity() == null)
                    return;

                getActivity().runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        _updateBanners(bannerItems, bannerImages);
                    }
                });

即可，完成。
