无法加载地图。错误接触谷歌服务器。这可能是一个身份验证问题 [英] Failed to load map. Error contacting Google servers. This is probably an authentication issue
问题描述
我搜索所有的日子，我无法找到答案......
I search all days and I can't find the answer...
万事俱备，但谷歌地图仍然无法片段，标签显示
everything is ready but google map still can't show on fragment with tab
我检查，我已经打开谷歌地图的Android v2和右API_KEY
I check that I already turn on google map android v2 and right API_KEY
我不知道发生了什么事！
I have no idea what happened!
MainActivity.java：
MainActivity.java:
public class MainActivity extends FragmentActivity implements
ActionBar.TabListener {
SectionsPagerAdapter mSectionsPagerAdapter;
ViewPager mViewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String titles[] = { this.getString(R.string.title_around),
this.getString(R.string.title_map),
this.getString(R.string.title_favorite),
this.getString(R.string.title_achievement), };
final ActionBar actionBar = getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
mSectionsPagerAdapter = new SectionsPagerAdapter(
getSupportFragmentManager());
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mSectionsPagerAdapter);
mViewPager
.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
@Override
public void onPageSelected(int position) {
actionBar.setSelectedNavigationItem(position);
}
});
for (int i = 0; i < titles.length; i++) {
actionBar.addTab(actionBar.newTab().setText(titles[i])
.setTabListener(this));
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override

mViewPager.setCurrentItem(tab.getPosition());
}
@Override
public void onTabUnselected(ActionBar.Tab tab,
FragmentTransaction fragmentTransaction) {
}
@Override

FragmentTransaction fragmentTransaction) {
}
public class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
// TODO 在這邊決定哪個位置要給什麼 View（Fragment）
Fragment fragment = null;
// TODO 建議先在之前就初始化好 4 個 Fragment
switch (position) {
case 0:

break;
case 1:

@Override

return 4;

@Override

}
MapsFragment.java：
MapsFragment.java:
public class MapsFragment extends Fragment{
static final LatLng NKUT = new LatLng(23.979548, 120.696745);
private GoogleMap map;
SupportMapFragment mMapFragment;
public MapsFragment() {
}
@Override
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;
}
}
Map_fragment.xml
Map_fragment.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"

<fragment
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment" />
</RelativeLayout>
的Manifest.xml：
Manifest.xml:
<!-- Google Map -->

android:protectionLevel="signature"/>
<uses-permission android:name="com.jertt.yummymap.permission.MAPS_RECEIVE"/>

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
<!-- The following two permissions are not required to use
Google Maps Android API v2, but are recommended. -->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<!-- end -->
<!-- Google Map API Key -->
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="key" />
<!-- end -->
解决方法：
我找到了解决办法！
如果您使用专用的密钥库申请API_KEY。你不能上传和与Eclipse安装的应用程序。
If you use private keystore to apply API_KEY. You cannot upload and install application with eclipse.
您需要的文件上传.apk文件到您的设备自己安装吧！
You need to upload .apk file to your device by yourself and install it!
感谢Tarsem和SRIKANTH GR帮助！
Thanks Tarsem and srikanth gr help!!
推荐答案
这听起来像你有问题，你的 API_KEY 这是从谷歌的 API访问<得到/ STRONG>，所以验证您的 API_KEY ，证书指纹和包的名称
it sounds like you have problem with your API_KEY which is obtained from Google API Access ,so verify your API_KEY , certificate fingerprints and package name
也用这里面的＆LT;舱单＆GT;
<uses-feature
android:glEsVersion="0x00020000"
android:required="true" >
</uses-feature>
和也验证了：＆LT;元数据....＆GT; 应该放在＆lt;应用＆GT; 标签
and also verify: <meta-data .... > should be inside <application> tag
PS。
1 同时加入尝试以下权限
1. Also try by adding following Permission
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
2 更改API密钥在的AndroidManifest.xml 后，必须 清除应用数据
要清除应用程序数据：
为到设置＆gt;应用经理＆gt;选择你的用途＆gt;点击清除数据
或 必须卸载应用程序在安装了！ 注意不要重新安装除非你完全卸载，以便应用到清除其数据完全
Or Must Uninstall The Application before installing it ! Note Don't Re-install unless you Completely Uninstall the Application in order to clear its Data completely
