我正在尝试使用AIDL开发2个应用程序(服务应用客户端应用程序)的设置.我目前有3个模块的设置：
> android-agent-framework(只保存AIDL文件的android库模块)
> android-agent(服务)
> android-example-client(客户端)
android-agent和android-agent-framework对第一个访问接口的依赖.
每当客户端调用bindService()时,它都会返回false,而在ServiceConnection中,不会调用onServiceConnected().同样在服务实现中,不调用onBind().日志中没有错误.
这是代码：
android-agent活动：
public class MyCompanyStartActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
Log.i(MyCompanyStartActivity.class.toString(),"Create MyCompanyStartActivity");
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ComponentName service = startService(new Intent(this,MyCompanyRequestService.class));
Log.i("tag",service.getClassName() + "::" + service.getPackageName());
}
}
android-agent服务：
public class MyCompanyRequestService extends Service {
@Override
public IBinder onBind(Intent intent) {
Log.i(MyCompanyRequestService.class.toString(),"Starting SmartRest Service");
return mBinder;
}
private final IMyCompanyRequestService.Stub mBinder = new IMyCompanyRequestService.Stub() {
@Override
public void sendData(String xid,String authentication,String data) throws RemoteException{
Log.i(MyCompanyRequestService.class.toString(),"sending data: " + data);
}
};
}
android-agent清单：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.mycompany.android.agent" >
<application
android:allowBackup="true"

</activity>
<!-- Services -->
<service

<action android:name="MyCompanyRequestService"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</service>
<!-- Permissions -->

</manifest>
android-example-client活动：
public class ClientStarter extends Activity {
protected IMyCompanyRequestService mycompanyRequestService = null;
@Override
public void onCreate(Bundle savedInstanceState) {
Log.i("tag","create client");
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
protected void onStart() {
super.onStart();
if (mycompanyRequestService == null) {
printServices();
Intent it = new Intent("MyCompanyRequestService");
it.setPackage("com.mycompany.android.agent.framework");
Log.i("tag","before binding service: " + it.getAction() + "::" + it.getPackage());
boolean serviceBinding = getApplicationContext().bindService(it,connection,Context.BIND_AUTO_CREATE);
Log.i("tag","service is bound: " + serviceBinding);
}
Handler handler = new Handler();
handler.postDelayed(new Runner(),10000);
}
@Override
protected void onDestroy() {
super.onDestroy();
unbindService(connection);
}
private ServiceConnection connection = new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName name,IBinder service) {
Log.i("service","Service connected");
mycompanyRequestService = IMyCompanyRequestService.Stub.asInterface(service);
Toast.makeText(getApplicationContext(),"Service Connected",Toast.LENGTH_SHORT).show();
Log.i("service","Service connected");
}
@Override
public void onServiceDisconnected(ComponentName name) {
Log.i("service","Service disconnected");
mycompanyRequestService = null;
Toast.makeText(getApplicationContext(),"Service Disconnected","Service disconnected");
}
};
private void printServices() {
ActivityManager manager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
for (ActivityManager.RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
Log.d("service",service.service.getClassName());
}
}
private class Runner implements Runnable {
@Override
public void run() {
Log.i("tag","starting");
LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
Location loc;
try {
Thread.sleep(10000);
} catch (InterruptedException e) {
Log.e(ClientStarter.class.toString(),"Error",e);
} while(true) {
try {
if (mycompanyRequestService != null) {
loc = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
Log.i(ClientStarter.class.toString(),loc.getLatitude() + " - " + loc.getLongitude() + " - " + loc.getAltitude());
mycompanyRequestService.sendData("test","auth",String.valueOf(loc.getLatitude()) + "," + String.valueOf(loc.getLongitude()) + "," + String.valueOf(loc.getAltitude()));
} else {
Log.i(ClientStarter.class.toString(),"service not yet available");
}
Thread.sleep(5000);
} catch (InterruptedException e) {
Log.e(ClientStarter.class.toString(),e);
} catch (RemoteException e) {
Log.e(ClientStarter.class.toString(),e);
}
}
}
}
}
尝试绑定服务之前的printServices()调用实际上列出了服务,因此它正在运行.
日志不包含任何错误,客户端最终在循环中运行,但服务仍为空.
也许有人之前遇到过类似的问题.
