Android 可以绑定到API 16（4.1.2）中的本地服务，但不能绑定到API 8（2.2）中的本地服务

我正在开发一个从API 8到API 16的应用程序

在启动时，程序应该绑定到我的本地服务

在使用API 16设置的AVD上进行测试时，我没有遇到任何问题，包括服务绑定或其他任何问题

在设置为API 8的AVD上进行测试时，它根本不会绑定到我的本地服务

这是我的日志：

我不明白的是，为什么会有SecurityException说我不允许绑定到服务。我可以在API 16中绑定到它，但在API 8中无法绑定。这不合逻辑

拜托，有人能帮忙吗

根据要求： 它不是整个代码，只是在活动开始时处理绑定的片段

private SocketService mainService;
private ServiceConnection serviceConn;
private boolean isServiceBound;

@Override
protected void onStart() {
    super.onStart();

    // First create ServiceConnection
    createServiceConnection();

    // Bind to SocketService
    Intent sInt = new Intent(this, SocketService.class);
    if ((isServiceBound = bindService(sInt, this.serviceConn,
            Context.BIND_AUTO_CREATE))) {
        Log.i("info", "Service has been bound.");
    }
}

@Override
protected void onStop() {
    super.onStop();

    if (isServiceBound) {
        unbindService(serviceConn);
        isServiceBound = false;
    }
}

@Override
protected void onDestroy(){
    super.onDestroy();

    if (isServiceBound) {
        unbindService(serviceConn);
        isServiceBound = false;
    }
}

private void createServiceConnection() {
    this.serviceConn = new ServiceConnection() {
        public void onServiceDisconnected(ComponentName name) {
            mainService = null;
            isServiceBound = false;
            Log.i("info", "Service disconnected.");
        }

        public void onServiceConnected(ComponentName name, IBinder service) {
            mainService = ((SocketService.SocketBinder) service)
                    .getService();
            isServiceBound = true;
            Log.i("info", "Service connected.");
        }
    };
}

服务的清单定义为：

  <service
        android:name="timesheetdb.Services.SocketService"
        android:exported="false"
        android:permission="normal" android:stopWithTask="true" android:enabled="true">
        <intent-filter>
            <action android:name="timesheetdb.Services.SocketService" />
        </intent-filter>
    </service>

尝试使用google api的用户仿真器（api 8的一部分）以下是服务定义的有效属性列表

http://developer.android.com/guide/topics/manifest/service-element.html

您可以尝试从清单中的服务定义中删除权限和stopWithTask属性

---

让我知道这是否有效

您可以发布用于绑定的代码以及服务的清单定义吗？根据您的请求，我已经发布了绑定代码和清单定义。这似乎起到了作用。谢谢，我很感激。权限属性在那里只是因为有一次我收到了警告。现在我不明白了。奇怪的
