How and how often does this exception occur?

This is the first time I have encountered this exception.

这个是Fabric抓到的日志，不是非常的频繁，不过每天都有就是了，涉及到终端和用户也是千奇百怪的，没有抓到特征。 Fatal Exception: java.lang.NullPointerException: Attempt to invoke interface method 'void xiaofei.library.hermeseventbus.IMainService.register(int, xiaofei.library.hermeseventbus.ISubService)' on a null object reference at xiaofei.library.hermeseventbus.HermesEventBus$HermesListener.onHermesConnected(HermesEventBus.java:288) at xiaofei.library.hermes.internal.Channel$HermesServiceConnection.onServiceConnected(Channel.java:284) at android.app.LoadedApk$ServiceDispatcher.doConnected(LoadedApk.java:1264) at android.app.LoadedApk$ServiceDispatcher$RunConnection.run(LoadedApk.java:1281) at android.os.Handler.handleCallback(Handler.java:815) at android.os.Handler.dispatchMessage(Handler.java:104) at android.os.Looper.loop(Looper.java:207) at android.app.ActivityThread.main(ActivityThread.java:5917) at java.lang.reflect.Method.invoke(Method.java) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:888) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:749)

这个问题我下一次进行改善。谢谢反馈！

[Xiaofei-it]

另外，你是怎么使用的？感觉很奇怪。之前反馈中从没看到这个问题。

我一个app中有两个进程，一个UI，一个service，然后就要了app内进程间通讯； 此外做了一个进程包含措施，这又是一个进程，用来保活UI进程和service 进程，使用https://github.com/Marswin/MarsDaemon 这个开源库； 发件人: Xiaofei [mailto:notifications@github.com] 发送时间: 2017年1月4日 15:09 收件人: eleme/HermesEventBus <HermesEventBus@noreply.github.com> 抄送: dongfanglinglong <dongfanglinglong@gmail.com>; Author <author@noreply.github.com> 主题: Re: [eleme/HermesEventBus] Exception: java.lang.NullPointerException: Attempt to invoke interface method 'void xiaofei.library.hermeseventbus.IMainService.register (#19) 另外，你是怎么使用的？感觉很奇怪。之前反馈中从没看到这个问题。 — You are receiving this because you authored the thread.

真的很奇怪啊，我这个问题先放着，看看有没有别人反馈。线上环境之前从没发现这个问题。可能和你用了其他库有关，我以后再查吧。

本来我想在那里做一个非空判断，不过这样就破坏了本来的逻辑，改动太大，可能会造成页面卡顿。

[dongfanglinglong]

嗯，我再等一段时间吧，再不行我就自己改吧 发件人: Xiaofei [mailto:notifications@github.com] 发送时间: 2017年1月4日 18:18 收件人: eleme/HermesEventBus <HermesEventBus@noreply.github.com> 抄送: dongfanglinglong <dongfanglinglong@gmail.com>; Author <author@noreply.github.com> 主题: Re: [eleme/HermesEventBus] Exception: java.lang.NullPointerException: Attempt to invoke interface method 'void xiaofei.library.hermeseventbus.IMainService.register (#19) 真的很奇怪啊，我这个问题先放着，看看有没有别人反馈。线上环境之前从没发现这个问题。可能和你用了其他库有关，我以后再查吧。 本来我想在那里做一个非空判断，不过这样就破坏了本来的逻辑，改动太大，可能会造成页面卡顿。 — You are receiving this because you authored the thread.
