无法加载地图.联系Google服务器时出错 这可能是一个身份验证问题

Question

我搜索了所有的日子,我找不到答案......

一切准备就绪,但谷歌地图仍然无法显示片段与标签

我检查我已经打开谷歌地图android v2和正确的API_KEY

我不知道发生了什么!

MainActivity.java:

MapsFragment.java:

public class MapsFragment extends Fragment{

    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.map_fragment,container, false);

        map = ((SupportMapFragment)getFragmentManager().findFragmentById(R.id.map)).getMap();

         mMapFragment = SupportMapFragment.newInstance();
         FragmentTransaction fragmentTransaction =
                 getFragmentManager().beginTransaction();
         fragmentTransaction.add(R.id.map,mMapFragment);
         fragmentTransaction.commit();

        return rootView;

    }

    <!-- end -->

解:

我找到了解决方案!

如果您使用私钥库来应用API_KEY.您无法使用eclipse上传和安装应用程序.

您需要自己上传.apk文件到您的设备并安装它!

谢谢Tarsem和srikanth gr帮助!!

Answer 1

这听起来像你有问题你API_KEY这是从谷歌获得API访问,因此验证API_KEY,证书的指纹和包名

里面也用这个 <manifest>

<uses-feature
        android:glEsVersion="0x00020000"
        android:required="true" >
    </uses-feature>

并且还要验证:<meta-data .... >应该在<application>标签内

PS.

1.另外尝试添加以下权限

<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>

2. After changing API key在AndroidManifest.xml 必由之路 Clear Application Data

清除应用程序数据:

要么去Settings>Application Manager>Select Your Application > Click on Clear Data

或者 Must Uninstall The Application 在installing it ! 注意之前不要Re-install除非你Completely Uninstall the Application为了clear its Data completely

Answer 2

我花了很多时间,有太多类似的问题.

我尝试添加自己的权限,WIFI_STATE权限,但真正的问题是在应用程序数据中.

在清单中更改API密钥后,您必须 "清除应用程序的数据"(或完全重新安装).

这有助于我和我希望这篇文章能够帮助某些人.

Answer 3

通过向清单添加权限解决了我的问题:

<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>

Answer 4

我有同样的问题,我的问题是我没有在控制台中激活服务:

1. 转到控制台:https://code.google.com/apis/console/
2. 转到服务部分
3. 启用Google Maps Android API v2
4. 按照documentacion中的所有步骤操作

Answer 5

如果您对auth有问题,请在Logcat中检查您的包名.如果您使用Android Studio,请检查您的build.gradle.当文件包含时applicationIdSuffix '.dev'.您应该添加.dev到您的包名称.

ei包名是:

com.company.main

在API控制台中写

... 9S.ME.DA.FE; com.company.main.dev
