    CustomMap customMap = new CustomMap();
    customMap.setArguments(bundle);
    return customMap;

Answer 1

copy SHA1 from logcat when you siged your apk click on finish and add this on your google play developer console project SHA-1 certificate fingerprint this will show your map with signeg apk

Answer 2

problem's lying here

<permission
android:name="com.baresso.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />

replace it with giving your own package name..

<permission
android:name="com.example.maptest.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />

and here

replace this

<uses-permission android:name="com.baresso.permission.MAPS_RECEIVE" />
with <uses-permission android:name="com.example.maptest.permission.MAPS_RECEIVE" />  

Answer 3

https://developers.google.com/maps/documentation/android/start

1. I think the problem is with the Obtaining an API Key Or With The SHA-1 Finger Print.
2. have You Give the application Package with the SHA-1 fingerprint in the Google Consol
3. install Google Play Service into Your Emulator or Android Device.
4. Please prefer Android Device for Map Testing .

Answer 4

Google Maps Will not work with the latest change in their policies which limits the usage of google map libraries directly.

To solve this either you have to include entire google maps as a third party plug in or you can display the google map in an webview and pass locations through a javascript html function.

for ex:--

<script>
function initialize()
{
document.getElementById('dummyDIV').innerHTML = '<div id="googleMap"     
style="width:'+screen.width+'px;height:'+screen.height+'px;"></div>';
var sURL1 = window.document.URL;
var sURL2 =sURL1.split("%20");
var sURL= sURL2[0];
for (j=1;j<sURL2.length;j++){
    sURL = sURL+' '+sURL2[j];
} 

var mapProp = {
  center:new google.maps.LatLng(19.155721,72.856025),
  zoom:10,
  disableDefaultUI:true, 
  zoomControl:true,
  mapTypeControl:true,
  mapTypeId:google.maps.MapTypeId.ROADMAP

  };

var map=new google.maps.Map(document.getElementById("googleMap"),mapProp);


   if (sURL.indexOf("?") > 0)
{
var bifurcatedURL = sURL.split("?");    

var everyMarker = bifurcatedURL[1].split("&");  
for (i=0;i<everyMarker.length;i++)
    {
        var markerDetails =everyMarker[i].split("+");
        var lat = (markerDetails[0]);
        var lon = (markerDetails[1]);
        var address =markerDetails[2];
        var type = markerDetails[3];
        var markerPosition = new google.maps.LatLng(lat,lon);
        map.setCenter(markerPosition);
        if(type=='a'||type=='A')
    var marker=new 
google.maps.Marker({position:markerPosition,icon:'atm_marker.png'});
        else if(type=='b'||type=='B')
 var marker=new google.maps.Marker
 ({position:markerPosition,icon:'branch_marker.png'});
        else if(type=='c'||type=='C')
var marker=new google.maps.Marker({position:markerPosition,icon:'pin_blue.png'});

            marker.setMap(map);
    var infowindow = new             google.maps.InfoWindow({content:address});
            listenMarker(marker,address,infowindow,map)
    }
}   
}

function listenMarker (marker,address,infowindow,map)
{
// so marker is associated with the closure created for the listenMarker function call
google.maps.event.addListener(marker, 'click', function() {
                    infowindow.open(map, marker);
                });
}

 google.maps.event.addDomListener(window, 'load', initialize);
</script>
