Google Map Showing Blank

I have Developed an application that have Google Map functionality so i use new google play services library but when i launch Google map activity its showing map but blank so what

Solution 1:

1. Check your API key carefully
2. Check your SHA key carefully
3. 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 .

Solution 2:

By seeing the 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).

it seams its problem with Authentication. and Code should have googleMap = fm.getMap();

// 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

EDIT :

Check Phone Location settings also..

Try these:

• Google Play Services:

  You have to download the latest Google Play Services com.android.vending-4.8.20.apk.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.

  Note: You have to download the latest Google play services because year by year latest version will be updated in internet.
