InterfaceLoader
- 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
为什么要用InterfaceLoader
- 因为不想用AIDL!

干掉难用的AIDL,InterfaceLoader就是这么爽InterfaceLoader的原理和亮点
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
interface-loader
- 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。
service-fetcher
- 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
在工程中引用
interface-loader
Via Gradle:
implementation 'com.jeremyliao:interface-loader:0.0.1'
service-fetcher
Via Gradle:
implementation 'com.jeremyliao:service-fetcher-rxjava2:0.0.1'
- 注意:service-fetcher依赖了rxjava2
快速开始
定义接口
public interface IXXX {
...
}
接口的实现和启动服务
- 定义Android Service
- 在onBind方法中调用InterfaceService.newService:
InterfaceService.newService()
client端接口调用
- 定义Activity
- 通过bindService获取IBinder
- 通过InterfaceLoader.getService调用接口的方法
InterfaceLoader.getService()
完整示例
我们以一个加减乘法的接口调用来说明这个示例
接口定义
public interface ILoaderDemo {
int plus(int a, int b);
int minus(int a, int b);
int multi(int a, int b);
}
接口实现和启动服务
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
连接服务和接口调用
用ServiceFetcher连接服务
Intent intent = new Intent(LoaderDemoService.ACTION);
intent.setPackage(getPackageName());
serviceFetcher = new ServiceFetcher(this, intent);
serviceFetcher.bindService();
用ServiceFetcher链式的连接服务
用InterfaceLoader调用接口
disposable.add(serviceFetcher.getService()
.map(new Function<IBinder, Integer>() {
@Override
public Integer apply(IBinder binder) throws Exception {
return InterfaceLoader.getService(ILoaderDemo.class, binder)
.plus(10, 20);
}
})
.map(new Function<Integer, String>() {
@Override
public String apply(Integer result) throws Exception {
return "result: " + result;
}
})
.subscribe(new Consumer<String>() {
@Override
public void accept(String result) throws Exception {
binding.tvContent.setText(result);
}
}));
别忘了activity退出的时候断开连接
serviceFetcher.unbindService();
完整的客服端代码
public class MainActivity extends AppCompatActivity {
ActivityMainBinding binding;
ServiceFetcher serviceFetcher;
final CompositeDisposable disposable = new CompositeDisposable();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
binding = DataBindingUtil.setContentView(this, R.layout.activity_main);
binding.setHandler(this);
binding.setLifecycleOwner(this);
Intent intent = new Intent(LoaderDemoService.ACTION);
intent.setPackage(getPackageName());
serviceFetcher = new ServiceFetcher(this, intent);
serviceFetcher.bindService();
}
@Override
protected void onDestroy() {
super.onDestroy();
serviceFetcher.unbindService();
if (!disposable.isDisposed()) {
disposable.dispose();
}
}
public void remotePlus() {
disposable.add(serviceFetcher.getService()
.map(new Function<IBinder, Integer>() {
@Override
public Integer apply(IBinder binder) throws Exception {
return InterfaceLoader.getService(ILoaderDemo.class, binder)
.plus(10, 20);
}
})
.map(new Function<Integer, String>() {
@Override
public String apply(Integer result) throws Exception {
return "result: " + result;
}
})
.subscribe(new Consumer<String>() {
@Override
public void accept(String result) throws Exception {
binding.tvContent.setText(result);
}
}));
}
public void remoteMinus() {
disposable.add(serviceFetcher.getService()
.map(new Function<IBinder, Integer>() {
@Override
public Integer apply(IBinder binder) throws Exception {
return InterfaceLoader.getService(ILoaderDemo.class, binder)
.minus(10, 20);

.map(new Function<Integer, String>() {
@Override
public String apply(Integer result) throws Exception {
return "result: " + result;
}
})
.subscribe(new Consumer<String>() {
@Override

binding.tvContent.setText(result);
}
}));

public void remoteMulti() {

.map(new Function<IBinder, Integer>() {
@Override
public Integer apply(IBinder binder) throws Exception {
return InterfaceLoader.getService(ILoaderDemo.class, binder)
.multi(10, 20);
}
