fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
}
LogCat error
Google Maps Android API﹕ Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors).
Answer1:
<ol><li>Check your API key carefully</li>
<li>Check your SHA key carefully</li>
<li>You should be connected to internet using WIFI before first time using Google map and wait 2-3 min till download map data etc. next time no need to connected with internet but if u want to search another location it must also be connected with internet using WIFI .</li>
</ol>
Answer2:By seeing the <strong>LogCat error Google Maps Android API﹕ Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors).</strong>
it seams its problem with Authentication. and Code should have <strong>googleMap = fm.getMap();</strong>
// Getting reference to the SupportMapFragment of activity_main.xml
SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
// Getting GoogleMap object from the fragment
googleMap = fm.getMap();
Try to use this... And Double check SHA1 key
<strong>EDIT</strong> :
Check Phone Location settings also..
Answer3:Try these:
<ul><li><strong>Google Play Services:</strong>
You have to download the latest Google Play Services
<a href="http://www.androidfilehost.com/?fid=23501681358540606" rel="nofollow">com.android.vending-4.8.20.apk</a>.In that site if google play
services wasn't working means you can find a lot of sites in
internet named com.android.vending 4.8.20.apk.
you can run the Google play Services by using the Command Prompt
adb install com.android.vending 4.8.20.apk.
<strong>Note:</strong> You have to download the latest Google play services because year by year latest version will be updated in internet.
