和我的Andr​​oid的manifest.xml

and my android manifest.xml

            </intent-filter>
        </activity>
    </application>

</manifest>

我也试着设置机器人：在我的应用程序标签可调试=真正的

I have also tried setting android:debuggable="true" in my application tag

任何帮助是极大AP preciated

Any help is greatly appreciated

推荐答案

所以，我终于发现了问题。
这是一个问题CORS

So I finally found the problem. It was a CORS issues

我有正确的设置在我的科尔多瓦config.xml中

I had the correct setting in my cordova config.xml

<access origin=".*" />

然而，当Zend Studio的内置了我的Andr​​oid项目该设置并没有得到转移到我RES / XML / config.xml中

However, when Zend studio built out my android project this setting did not get transferred over to my res/xml/config.xml

添加接入原线在该文件中的一切后开始按预期工作。

After adding the access origin line in that file everything started working as expected.
