Failed to load map. Error contacting Google servers. This is probably an authentication issue
I search all days and I can't find the answer...
everything is ready but google map still can't show on fragment with tab
I check that I already turn on google map android v2 and right API_KEY
I have no idea what happened!
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
public void onTabSelected(Tab tab, FragmentTransaction fragmentTransaction) {
mViewPager.setCurrentItem(tab.getPosition());
}
@Override
public void onTabUnselected(ActionBar.Tab tab,
FragmentTransaction fragmentTransaction) {
}
@Override
public void onTabReselected(ActionBar.Tab tab,
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:
fragment = new AroundFragment();
break;
case 1:
fragment = new MapsFragment();
break;
case 2:
fragment = new FavoriteFragment();
break;
case 3:
fragment = new AchievementFragment();
break;
default:
break;
}
return fragment;
}
@Override
public int getCount() {
return 4;
}
@Override
public CharSequence getPageTitle(int position) {
// TODO 在這邊決定每一個 View 的 title
switch (position) {
case 0:
return getString(R.string.title_around);
case 1:
return getString(R.string.title_map);
case 2:
return getString(R.string.title_favorite);
case 3:
return getString(R.string.title_achievement);
}
return null;
}
}
}
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;
}
}

Solution:
I found the solution!!!
If you use private keystore to apply API_KEY. You cannot upload and install application with eclipse.
You need to upload .apk file to your device by yourself and install it!
Thanks Tarsem and srikanth gr help!!
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
also use this inside <manifest>
<uses-feature
android:glEsVersion="0x00020000"
android:required="true" >
</uses-feature>
and also verify: <meta-data .... > should be inside <application> tag
PS.
1. Also try by adding following Permission
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
2. After changing API key in AndroidManifest.xml Must Clear Application Data
To Clear Application Data :
Either Go to Settings>Application Manager>Select Your Application > Click on Clear Data
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
I spent so much time, there are too many similar questions.
I tried to add own permission, WIFI_STATE permission, but the real problem was in application data.
After you change API key in manifest, you MUST "Clear data" of your application (or completely re-install).
This helps me and I hope this post will help somebody.
My problem was solved by adding permission to the manifest:
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
I have the same issue, and my problem was that I didn't activate the service in the console:
- Go to console: https://code.google.com/apis/console/
- Go to services section
- Enable Google Maps Android API v2
- Follow all the steps in the documentacion
If you are have a problem with auth, check in Logcat your package name.
If you use Android Studio check out your build.gradle. When file contains applicationIdSuffix '.dev'. You should add .dev to your package name.
e.i. package name is:
com.company.main
In API console write
...9S.ME.DA.FE;com.company.main.dev
