如何将数据从Android服务发送到其AIDL存根

interface IDataTransferService {
    void sendData(String data);
}

public class DataTransferService extends Service {
    private final IDataTransferService.Stub mBinder = new IDataTransferService.Stub() {
        @Override
        public void sendData(String data) {
            // 处理接收到的数据
        }
    };

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return mBinder;
    }
}

<service
    android:name=".DataTransferService"
    android:exported="true">
    <intent-filter>
        <action android:name="com.example.DATA_TRANSFER_SERVICE" />
    </intent-filter>
</service>

Intent intent = new Intent("com.example.DATA_TRANSFER_SERVICE");
intent.setPackage("com.example.serviceapp"); // 服务端应用的包名
startService(intent);

aidl -p . IDataTransferService.aidl

private ServiceConnection mConnection = new ServiceConnection() {
    @Override
    public void onServiceConnected(ComponentName name, IBinder service) {
        IDataTransferService dataTransferService = IDataTransferService.Stub.asInterface(service);
        try {
            // 调用服务端方法发送数据
            dataTransferService.sendData("Hello from client!");
        } catch (RemoteException e) {
            e.printStackTrace();
        }
    }

    @Override
    public void onServiceDisconnected(ComponentName name) {
        // 服务连接断开时的处理逻辑
    }
};

Intent intent = new Intent("com.example.DATA_TRANSFER_SERVICE");
intent.setPackage("com.example.serviceapp"); // 服务端应用的包名
bindService(intent, mConnection, BIND_AUTO_CREATE);

try {
    // 调用服务端方法发送数据
    dataTransferService.sendData("Hello from client!");
} catch (RemoteException e) {
    e.printStackTrace();
}
