a light lib of android-common-utils for use.
-
简述：ipc就是进程间通信, 所以本库就是进程间通信的框架。 为了app间通信，我特意写了2个库：ipc和ipc-server (就是指客户端和服务端)
-
原理：
-
已经使用ipc框架的案例：
- 开源库 android-fully-log
- android完整的日志系统，通过Ipc来读写日志。支持日志的格式化，加解密，过滤等。
-
本库的特点：
-
1, 支持app间的进程间通信。
-
2, 支持多个客户端(client)和一个服务端(server)通信。服务端接收到消息后可以群发给其他客户端。 ps: 当前设计只支持1个服务端.
-
3, client 和 server 都可以发送消息。但是server端不能发送reply消息。
-
4，支持3种消息模式：
- 广播(broadcast): 就是说server端接收到广播后可以 处理后直接下发给所有的client。
- 回执(reply)： 相当于1个client和1个server之间的通信。 server端接收到消息处理后回执消息给对应的client.
- 消费(comsume): 就是client或者server可以发送一条comsume的消息，只要有一个客户端消耗了，消息的传递也就终止了。
-
5, 消息的处理在单独的子线程。(考虑到比如文件操作什么的)
-
使用介绍：
- 步骤1：添加权限 and 导入对应的库：
-
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="com.heaven7.android.ipc.service"/> //客户端需要导入的
compile 'com.heaven7.android.ipc:ipc:2.1.1'
//服务端需要导入的
compile 'com.heaven7.android.ipc.server:ipc-server:1.1.1' - 2：创建MessageClient和MessageServer对象。（代表消息客户端和服务端）
- 3：绑定和解绑消息服务： 调用MessageClient.bind()/MessageClient.unbind() , MessageServer同理.
- 4: 发送和接收消息。
- 发送： boolean sendMessage(Message msg , @IpcConstant.MessagePolicy int policy)
- (MessageClient和MessageServer这点基本相同，只是server端不能发送reply消息)
- 处理/接收消息：
- server只有1个方法：
//处理来源消息，返回新的消息，如果返回null就表示忽略这条消息
protected abstract Message processMessage(int policy, Message msg);
- client有3个方法分别代表3种消息。
/** 接收广播消息
* called when client receive a broadcast message from server
* @param msg the new message
*/
protected void onReceive(Message msg){
}
/** 处理消耗模式的消息
* @param msg the new message
* @return true if you handle it .
*/
protected boolean consumeMessage(Message msg){
return false;
}
/** 处理reply消息
* called when server reply message to the message requester.
* @param msg the new message
*/
protected void handleReplyMessage(Message msg){
} 1, module -> android-ipc
-(1), desc: this is a common ipc lib of android.
-(2), features:
- first, support multi clients communicate with a server.
- second, support client can send a message to server, so is server.
- third, support multi work policy(or mode): broadcast, consume, reply
- forth, server support work in background thread.
-(3), calling flow:
// 1, init client and server .offen in multi app.
mClient = new MessageClient(this){
@Override
protected void afterConnected() {
showToast("client is connected.");
Logger.i(TAG, "MessageClient_afterConnected", "client is connected.");
}
//broadcast policy message
@Override
protected void onReceive(Message msg) {
Logger.i(TAG, "MessageClient_onReceive", toTestString(msg));
}
//consume policy message
@Override
protected boolean consumeMessage(Message msg) {
Logger.i(TAG, "MessageClient_consumeMessage", toTestString(msg));
return super.consumeMessage(msg);
}
// reply policy message.
@Override
protected void handleReplyMessage(Message msg) {
Logger.i(TAG, "MessageClient_handleReplyMessage", toTestString(msg));
}
};
mServer = new MessageServer(this){
//this is very important for server handle client message.
@Override
protected Message processMessage(int policy, Message msg) {
msg.getData().putString("processor","MessageServer");
return msg;
}
@Override
protected void afterConnected() {
showToast("server is connected.");
Logger.i(TAG, "MessageServer_afterConnected", "server is connected.");
}
};
//2, bind and unbind
//for client
mClient.bind();
mClient.unbind();
//for server
mServer.bind();
mServer.unbind();
// send message , client and server both can do it.
boolean sendMessage(Message msg , @MessageService.MessagePolicy int policy);
mClient.sendMessage(...);
mServer.sendMessage(...); the more to see in demo [IpcTestActivity](https://github.com/LightSun/android-common-util-light/blob/master/CommonUtil-mini/app/src/main/java/com/heaven7/android/mini/demo/sample/IpcTestActivity.java).
