android – 在bindService()之后没有连接的AIDL服务

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：

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.

解决方法

经过所有文件的另一轮后,我发现了我的错误.

我需要改变：

Intent it = new Intent("MyCompanyRequestService");
it.setPackage("com.mycompany.android.agent.framework");

至：

Intent it = new Intent("MyCompanyRequestService");
it.setPackage("com.mycompany.android.agent");

Intent的包需要匹配应用程序的包而不是服务的包.
