- InterfaceLoader是Android跨进程接口调用框架,可以完美替代Android AIDL
- 史上最好用的Android跨进程接口调用框架
- 新增service-fetcher,可以链式连接service和调用方法,并帮你处理重连、掉线等问题
- 因为不想用AIDL!
- 因为不想用AIDL!!
- 因为不想用AIDL!!!
总的来说,分为两个库:interface-loader和service-fetcher,可单独使用interface-loader,也可一起使用
- 主要解决了跨进程方法调用的问题
- 封装了跨进程通信需要的打包和拆包,让跨进程接口调用更好用
- 相对AIDL:
- AIDL的跨进程通信是一种典型的代理模式,由.aidl文件生成client端的proxy和server端的binder,但是我觉得生成的代码总觉得看起来很别扭,也很难用。
- 所以interface-loader使用动态代理代替了AIDl的代码生成,非常巧妙。不仅减少了生成的代码,也让跨进程通信的使用体验更接近普通的接口调用,这就是interface-loader的奇妙之处。
- 主要解决了连接远程服务的问题
- 链式处理服务连接和接口调用
- 封装和处理了服务掉线、重连等异常场景
Via Gradle:
implementation 'com.jeremyliao:interface-loader:0.0.1'
Via Gradle:
implementation 'com.jeremyliao:service-fetcher-rxjava2:0.0.1'
- 注意:service-fetcher依赖了rxjava2
public interface IXXX {
...
}
- 定义Android Service
- 在onBind方法中调用InterfaceService.newService:
InterfaceService.newService()
- 定义Activity
- 通过bindService获取IBinder
- 通过InterfaceLoader.getService调用接口的方法
InterfaceLoader.getService()
我们以一个加减乘法的接口调用来说明这个示例
public interface ILoaderDemo {
int plus(int a, int b);
int minus(int a, int b);
int multi(int a, int b);
}
定义一个service:
public class LoaderDemoService extends Service {
public static final String ACTION = "intent.action.loader";
@Override
public void onCreate() {
super.onCreate();
}
@Override
public void onDestroy() {
super.onDestroy();
}
@Override
public IBinder onBind(Intent intent) {
return InterfaceService.newService(ILoaderDemo.class, new ILoaderDemo() {
@Override
public int plus(int a, int b) {
return a b;
}
@Override
public int minus(int a, int b) {
return a - b;
}
@Override
public int multi(int a, int b) {
return a * b;
}
});
}
}
- 关键点是在onBind中调用InterfaceService.newService
- 当然还需要在androidManifests中注册服务
