xiaofei-it / hermeseventbus Goto Github PK

这两个问题都一直频繁出现（尤其在sony的一台机器上，其他的还好）

版本：compile 'xiaofei.library:hermes-eventbus:0.2.0'

一个process进程，连接主程序，主要post消息 thread ==>（in main thread）
是我的配置问题，还是设备问题？
这两个问题，出现的频率基本上一小时~两小时出现一次

UPDATE：

通常在使用，高德地图或其他软件时发生
另外程序内部，经常报DeadObjectException，所以主程序内部通信采用EventBus发送消息，但是在Activity-create时仍用HermesEventBus-register（这个问题，基本所有的机器都提示，改了之后没有）

最新版本中在主进程启动service，子进程即使在退出前调用HermesEventBus.getDefault().destroy();然后杀死子进程（Process.killProcess(Process.myPid());）后，再启动子进程，主进程使用HermesEventBus post事件后仍然产生异常：android.os.DeadObjectException，调试发现是主进程持有已经dead的子进程service造成的，可在子进程退出前该怎么处理呢？

step 3: （不同app之间通信)
在app间收发的事件类必须有相同的包名、相同的类名和相同的方法？ 这样似乎限制太多啦，而且这样还能在同一个手机上装这样两个应用吗？

楼主，报这个错误，怎么搞？？？

以下是我的测试数据，每次事件中带有1K bytes的数据，耗时取的是1000次事件的平均值：
机型 broadcast耗时 Hermes耗时
Nexus6 11.83ms 7.79ms
LG D858 9.21ms 11.6ms
小米note 5.08ms 10.77ms
oppo A31 28.66ms 13.4ms

我看你是在发送事件事件时每次都做了锁和解锁，感觉可能是这里产生了耗时。但service bind成功之后已经是同步接口了，感觉多线程的情况才需要做锁或者synchronized。
请问基于什么考虑做锁呢？

个人感觉HermesEventBus没有完全实现粘性特征，HermesEventBus必须在register之后才能进行事件的收发；而EventBus先发送粘性事件，后进行注册依然能收到。估计这可能是评论区中说收不到事件的主要原因，HermesEventBus和EventBus还是有一些区别的。

在多个APP之间通讯的时候，在子 APP 中Application调用connect主APP，然后调用post，主APP不能收到该Event，还有主APP如何把事件post给子APP因为主APP是调用init方法的默认使用的EventBus的post了，也就是默认当前进程post，而子app是默认给主APP post想给自己post也没提供方法，我是没用起来

请问这个项目还在维护吗？因为一直是0.3.0版本，一直没有再更新了

It happens when main process get closed and other service is running

接入hermes-eventbus:0.2.0，在debug模式下安装运行都没有问题，但是正是发布打包安装就报

我在主app里面写的eventbus接收事件，但是子app发过来主app收不到，或者子app就没有发送成功。
主app的接收事件处理
@subscribe(threadMode = ThreadMode.MAIN)
public void helloEventBus(MessageEvent message) {
text_info.setText(message.name);
System.out.println("传递过来的数据:--->>>"+message.name);
}
子app的发送事件
HermesEventBus.getDefault().post(new MessageEvent("tom","123456"));

事件类都是相同的包名，相同的类名，里面结构体都一样。
package com.cn.wt.eventbus;

我项目还依赖了其他的项目,可以在主项目与依赖项目之间通信吗?也可以说是模块之间通信,需要怎么做呢?感谢大神可以帮忙解答

Hello Team,

Recently i have updated my application to support android oreo , And we have changed support version to 26 and compile sdk version to 26.

At runtime we land up with issue from HermsEventBus , i.e ActionBarActivity def not found in TypeUtills.java

private static final HashSet<Class> CONTEXT_CLASSES = new HashSet>() {
{
add(Context.class);
add(ActionBarActivity.class);
add(Activity.class);
add(AppCompatActivity.class);
add(Application.class);
add(FragmentActivity.class);
add(IntentService.class);
add(Service.class);
}
};

Please let us know how to solve this problem , it seems they have removed ActionBarActivity from support libraries ,Previously it was deprecated.

Regards,
Anil Raavi.

遇到这种情况有手动重连的方法吗？

所有的数据类型都可以么？接口和Context可以么？我试了下，没有成功。

我在项目中集成了库之后编译报错：

我的项目之前集成了actionbarsherlock，引用V7包就会报这个错误，可否把V7的依赖去掉啊？

请问库里面的 values.xml 中的 app_name 是否可以移除？会导致 manifest merger failed 。

使用hermesEventBus 框架，post 方法参数是string类型的不报错，但是使用了自定义的对象，报如下错误

我目前是在尝试试用，但我发现一个问题，我主进程被强制kill掉后，子进程也同时kill掉，但是过会儿两个进程又重启了？

不知道是不是我使用的不恰当，请大神指教，我非常急……

主app被杀死，但是子app程还存活的情况下，重启主app子app无法Connecte到主app了，如何解决呢

错误log 如下

我在使用HermesEventBus的时候，当我打包之后自己反编译发现清单文件中多了许多权限的增加，还有一个HermesEventBus$Service的申明 ，这个原因直接导致在腾讯手机管家上面报毒了~可能申请了敏感的权限，我从多出的权限推测可能是SYSTEM_ALERT_WINDOW这个原因

HermesEventBus$Service 这个占用内存太大了 能不能优化一下。

APP中添加了一个 Service，并在mainfest中配置service为android:process=":TestService"。从service中POST事件，主界面可以正常收到消息。按返回键退出主界面后，再次打开无法收到消息。
想了一下，可能init是在主APP的application中初始化的不行，尝试在application中初始化，没有效果。
看init源码如下：
public void init(Context context) {
mContext = context.getApplicationContext();
mMainProcess = isMainProcess(context.getApplicationContext());
if (mMainProcess) {
Hermes.init(context);
Hermes.register(MainService.class);
mMainApis = MainService.getInstance();
} else {
mState = STATE_CONNECTING;
Hermes.setHermesListener(new HermesListener());
Hermes.connect(context, Service.class);
Hermes.register(SubService.class);
}
}
在Service中执行init时，mMmainProcess为false,也就是永远不能从服务来执行初始化，可是现实确是往往service的生命周期都比前台进程要长。
作者能不能指点一下，如何解决这个问题。

when you go inside of activity manager #getRunningAppProcesses can also return null, In such case following exception happens.Please have a look

When using HermesEventBus, these two debug messages could also include the process ID, as in android.os.Process.myPid()

D/EventBus: No subscribers registered for event class com.testapp..EventTest
D/EventBus: No subscribers registered for event class org.greenrobot.eventbus.NoSubscriberEvent

This would make it more clear that it's HermesEventBus and when there are multiple processes, why this message appears even when delivered.

1. EventBus不太适合用Hermes，因为EventBus只调用方法不需要返回值以及等待返回，aidl声明有个oneway关键字，执行aidl方法时候是不阻塞调用

2. 绑定服务的时机，关于作者开一个服务，多个进程同时去通过aidl绑定这个服务发布事件这点非常好，但是绑定服务不应该是在init时候，而是在子进程发布事件，子进程注册事件的时候判断有没有绑定服务，没有连接就去绑定

3. 发布事件，目前是发布一个跨进程的事件所有进程都接收，我觉得没有必要所有进程接收，post远程事件的时候多个processName的参数，发布事件到指定的进程。

4. EventBus用多了就乱，我觉得以接口的方式定义event，接收者实现这个接口，发布者通过这个接口发布事件，目前我实现了两种方式一种是动态代理自动实现使用者定义的接口，一种是apt的方式自动那个实现使用者定义的接口。

以上是个人建议，总的来说开一个服务，多个进程同时去通过aidl绑定这个服务发布事件这点想法很好

使用gradle的方式引入是好的，但是把源码搞到工程中，编译，就不能正常使用了

主进程间互相传递对象，没问题，主进程给其它进程post对象，会被解析成LinkedTreeMap

在一个应用里面，子进程（Service）发出的事件，主进程收得到，但是主进程发出的事件，子进程收不到。

接入后，一直在报NullPointerException
1.xiaofei.library.hermeseventbus.HermesEventBus$HermesListener.void onHermesConnected(java.lang.Class)(SourceFile:291)
xiaofei.library.hermes.internal.Channel$HermesServiceConnection.void onServiceConnected(android.content.ComponentName,android.os.IBinder)(SourceFile:288)
2.Attempt to invoke interface method 'void xiaofei.library.hermeseventbus.a.a(int, xiaofei.library.hermeseventbus.b)' on a null object reference

为什么会出现post一次事件，监听Activity会受到两次呢
