问题1：java.lang.IllegalArgumentException: Service not registered
原因：重复解绑
unbindService(connection)问题2：java.lang.IllegalStateException: closed
场景：okhttp拦截器response.body.toString()后会被close，再次执行时会异常closed
问题3：java.lang.IllegalArgumentException: bad base-64
场景：android.util.Base64.decode(content,Base64.URL_SAFE)时报错
原因：content数据源有问题，当然场景和原因还有其他的。
问题4： java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification. Make sure the content of your adapter is not modified from a background thread, but only from the UI thread. Make sure your adapter calls notifyDataSetChanged() when its content changes. [in ListView(2131296524, class android.widget.ListView) with Adapter(class android.widget.HeaderViewListAdapter)]
原因：当数据源发生改变，未进行adapter的更新，加上notifyDataSetChanged即可
问题5：更新中...
