I think its due to add(ActionBarActivity.class); in > xiaofei.library.hermes.util.TypeUtils.java

For temporarily solving this issue, I created a empty class android.support.v7.app.ActionBarActivity.java and extend to AppCompatActivity and my app starting running again :)

package android.support.v7.app;

/**
 * Created by blackadmin on 07/10/17.
 */

public class ActionBarActivity extends AppCompatActivity {
}

Service communication

Hi! Is possibile use this library for a communication Activity- Service???

启动第2个app进程的时候发现service0无法绑上

之前service0 启动后 验证 service 已经起～
public static boolean isServiceExisted(Context context, String className) {
ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.RunningServiceInfo> serviceList = activityManager.getRunningServices(Integer.MAX_VALUE);
if(!(serviceList.size() > 0)) {
return false;
}
for(int i = 0; i < serviceList.size(); i++) {
ActivityManager.RunningServiceInfo serviceInfo = serviceList.get(i);
ComponentName serviceName = serviceInfo.service;
if(serviceName.getClassName().equals(className)) {
return true;
}
}
return false;
}

但是到了 B APP进程里 总是绑不上～

第二个APP

按照文档上写的，但是第二个APP拿不到数据

如果调用的方法参数是字节数组是否支持，看文档说是基于json的

建议修改一下Readme，描述存在错误、过于激进

update

Can't send or receive data larger then 100k

For example, I changed this code in demo UserManager class.

    @MethodId("getUser")
    @Override
    public String getUser() {
        // I tried 64k works.
        return new String(new byte[1024*100]);
    }

This got exception:

07-07 15:59:59.325 25466-25466/? E/JavaBinder: !!! FAILED BINDER TRANSACTION !!!
07-07 15:59:59.325 25466-25466/? E/HERMES_INVOCATION: Error occurs. Error 1: Remote Exception: Check whether the process you are communicating with is still alive.

I suppose this hit the limit of android IPC max data size. But 100k or 10m is not a big size for modern android device.

请问下 跨进程通信最大支持的数据量是多少？

我们现在用的aidl最多只支持到2M，所以后来这部分是用sharememory解决的，麻烦问下用你们的框架是否能解决数据量的问题？

关于这个库的个人理解~

@ClassId(“Singleton”)
public interface ISingleton {

    @MethodId(“setData”)
    void setData(String data);

    @MethodId(“getData”)
    String getData();

}

@ClassId(“Singleton”)
public class Singleton {
    ...

    @MethodId(“setData”)
    public void setData(String data) {
        mData = data;
    }

    @MethodId(“getData”)
    public String getData() {
        return mData;
    }

}

1. ISingleton 基本就是 java 版的 AIDL
2. Singleton 可以看做 extends ISingleton.Stub (代入到AIDL视角的话)
3. 底层由 Service + Binder 实现
4. 使用了动态代理，某种程度上有点像Retrofit

不知道有没有理解偏了。

~~~~delete qusition ，It is in another project

在另一个项目下~~发错了项目,没找到如何删除问题~~~~

不理解

看了半天，还是不理解。

Activity 作为参数传递

我看了代码，如果Activity作为参数传递，接收到的是对方进程的Application context . 正常跳转是没问题，但是如果是需要返回值的startActivityForResult。就需要取得Activity的实例进行跳转。context 是不包含此方法的。我要怎么去获取传递过来的Activity 的实例？

Eclipse完全被抛弃了吗？

大神，我们公司目前还停留在Eclipse的阶段，我是不是没办法用你这个神器了？

看了下源码，貌似加了不少锁，性能有点不太够

1000 次，接口计算和回调用了1204毫秒
一样也是使用动态代理来实现的的简单demo， 耗时是333毫秒
目前手机是一加8，系统是Android 10

Error with java.util.Date type

Android 5.1.0 on Genymotion.

This test case is just a little bit modification from Hermes demo.
Interface:

@ClassId("UserManager")
public interface IUserManager {

    @MethodId("getUser")
    String getUser();

    @MethodId("getDate1")
    Date getDate1();

    @MethodId("getDateText")
    String getDateText();

}

Implemantation:

@ClassId("UserManager")
public class UserManager implements IUserManager {

    private static UserManager sInstance = null;

    private UserManager() {

    }

    public static synchronized UserManager getInstance() {
        if (sInstance == null) {
            sInstance = new UserManager();
        }
        return sInstance;
    }

    @MethodId("getUser")
    @Override
    public String getUser() {
        return "Xiaofei";
    }
    @MethodId("getDate1")
    @Override
    public Date getDate1() {
        return new Date();
    }
    @MethodId("getDateText")
    @Override
    public String getDateText() {
        return "DateText";
    }
}

Client side code:

IUserManager userManager = Hermes.getInstanceInService(HermesService.HermesService1.class, IUserManager.class);
                Date date = userManager.getDate1();
