Solved by declaring the onEventMainThread method and EventBus.getDefault().register(this); in a same fragment (should be declared in same class) Declaring the

问题 What is the best place to register and unregister to an event bus (like otto, EventBus, or tinybus) in an Activity and why? onCreate()-onDestroy() onStart()-onStop() onResume()-onPause() Otto's example uses onResume()-onPause(), EventBus's mentions onStart()-onStop(), and we needed to use onCreate()-onDestroy() in our app to update the activity's UI even when it was in the background. So I guess it can be any of the three depending on the nature of the events and their handling, but I was

问题 I have implemented a service, where I handle the state changes(connect, disconnect, onServiceDiscoverd, onCharacteristicChange etc) and receiving data from another device through gatt Server. My question is, Can the events be handled efficiently using Greenrobot Eventbus replacing broadcast receiver between service and Activity ? 回答1: Unlike LocalBroadcastManager, EventBus is more simple to use. You only go via 3 steps: 1- Create an event class. A simple Java class that represent the response

IPC in Android using GreenRobot eventbus

阅读更多关于 IPC in Android using GreenRobot eventbus

I need to communicate with a remote service, using (greenrobot) EventBus. Unfortunately, it does not seem to work with IPC. Looking at the code, I don't see a workaround either. Any help would be appreciated ! Bonus question - are there any other EventBuses (for Android) which support IPC ? I need to communicate with a remote service, using (greenrobot) EventBus. The entire point of greenrobot's EventBus, like Square's Otto and LocalBroadcastManager , is to not use IPC. Any help would be appreciated ! Don't use greenrobot's EventBus for IPC. Use one of Android's myriad IPC mechanisms for IPC:
