1 RemoteApp和LocalApp使用相同的aidl文件(包名和文件名都一样)
package com.song.test.RemoteTimeService.aidl
interface IRemoteTimeService{
/**
* 获取当前时间
*/
String requestCurrentTime();
}
2 在RemoteApp中暴露出一个service并在onBind()的时候返回IRemoteTimerService.Sub
public class RemoteTimeService extends Service {
@Nullable
@Override
public IBinder onBind(Intent intent) {
return new RemoteBinder();
}
class RemoteBinder extends IRemoteTimeService.Stub {
public String requestCurrentTime(){
return "remote time " +System.currentTimeMillis();
}
}
}
3 RemoteApp中启动RemoteTimeService, 记得AndroidManifest.xml中声明一下
<service android:name="com.song.test.RemoteTimeService" android:process=":remote" android:exported="true" />
startService(new Intent(this, RemoteTimeService.class));
4 LocalApp中粘贴一份IRemoteTimeService.aidl文件然后sync project会生成aidl的实现，之后绑定远程服务就可以调用远程进程中的方法了
Intent intent = new Intent();
intent.setComponent(new ComponentName("com.song.test","com.song.test.RemoteTimeService"));
ServiceConnection conn = new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName componentName, IBinder iBinder) {
try {
IRemoteTimeService adService = IRemoteTimeService.Stub.asInterface(iBinder);
String s = adService.requestCurrentTime();
Toast.makeText(MainActivity.this, s, Toast.LENGTH_SHORT).show();
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public void onServiceDisconnected(ComponentName componentName) {
}
};
bindService(intent, conn, Service.BIND_AUTO_CREATE);
注意事项：
1 bindService()的时候的intent在setComponent() 一定要设置包名和远程服务的全类名
2 RemoteApp中的service一定要指定 android:exported="true"
3 IRemoteTimeService中方法传递对象，需要把对象实现parceble
4 aidl文件只是一个接口文件，定义remote和local的通信协议
