Google Map Doesn't Show Anything

Question

I'm using a MapFragment to display a google map. I think I have everything done right in code but map doesn't show anything enter image description here I guess it's API Key issue.

this is how I got it:

Used this command to generate SHA1 Fingerprint: keytool -list -v -keystore /Users/[USERNAME]/[debug.keystore path] -alias androiddebugkey -storepass android -keypass android

Created new project in Google developer console, enabled Google Maps Api V2, created new Android Key in Credentials

This is my project credentials from google developer console: enter image description here

and this is Manifest file:

    <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:versionCode="1" android:versionName="1.0" package="erpus.distribution" android:installLocation="auto">

  <uses-permission android:name="android.permission.INTERNET" />
  <meta-data android:name="android.app.searchable" android:resource="@xml/searchable" />
</manifest>

Any Suggestions?

Edit: I'm writing on Xamarin. Here's My fragment if anyone needs it:

public class ContractorMapFragment : Fragment {
    View view;
    private static int layoutId;

    public override void OnActivityCreated(Bundle savedInstanceState) {
        base.OnActivityCreated(savedInstanceState);

        MapFragment mapFrag = (MapFragment)FragmentManager.FindFragmentById(Resource.Id.map);
        GoogleMap Map = mapFrag.Map;
        if (Map != null) {
            Map.MapType = GoogleMap.MapTypeNormal;
            Map.UiSettings.CompassEnabled = true;
            Map.MyLocationEnabled = true;
        }
    }

    public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        if (view != null) {
            ViewGroup parent = (ViewGroup)view.Parent;
            if (parent != null) {
                parent.RemoveView(view);
            }
        }

        try {
            if (layoutId == 0)
                layoutId = Resource.Layout.MapFragmentLayout;
            view = inflater.Inflate(layoutId, container, false);
        }
        catch (InflateException e) {

        }
        return view;
    }
}

And View:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<fragment
    android:id="@+id/map"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    class="com.google.android.gms.maps.MapFragment" />

If your map not showing while you run your release mode apk?? — Piyush, Dec 02 '14 at 12:46
@PiyushGupta sorry I didn't really understand what you asked. I'm running it on debug mode. — arsena, Dec 02 '14 at 12:49
Try to add browser key and check if it works if it does then the problem is with the SHA (don't release the apk with the browser key) — meh, Dec 02 '14 at 12:51
@meh still nothing. anyway why would browser key work on android? — arsena, Dec 02 '14 at 12:58
If you generate a signed apk, notice that you must debug/run your app with the same debug.keystore that you have used to generate your SHA finger print — Rami, Dec 02 '14 at 12:59
I had same issue when i created map api key from one machine and i was running my application from different machine. — Richa, Dec 02 '14 at 13:01
@misho Must be sure its only because of different SHA. So have yu created API key some other PC and copy source code to another machine and run the app?? — Piyush, Dec 02 '14 at 13:02
@PiyushGupta yes, i did this before but then created new `api key` from the pc I'm using right now. — arsena, Dec 02 '14 at 13:06
It seems that you have problem in your fragment code. Give us .java code. — Anatol, Dec 02 '14 at 13:14
@Anatol I'm writing on Xamarin with C#. I can post it if you wish — arsena, Dec 02 '14 at 13:19
@misho oh. Sorry. i Can't help you so. But you really should do this for other participants. — Anatol, Dec 02 '14 at 13:20
@Anatol thanks anyways but still, I strongly doubt that there's something wrong with the code. — arsena, Dec 02 '14 at 13:31

Xamarin is using a different debug.keystore!

keytool -exportcert -alias androiddebugkey -keystore ~/.local/share/Xamarin/Mono\ for\ Android/debug.keystore | openssl sha1 -binary | openssl base64

That should solve your problem.

Thanks for your response. CMD says `'openssl' is not recognized as an internal or external command`. Am I pasting the command correctly? http://i.imgur.com/untqNrW.png – arsena Dec 19 '14 at 09:09
For Windows users you have to install openssl for the command line (probably through cygwin. Please check this response: http://stackoverflow.com/a/7201252/1117968 – der_michael Dec 19 '14 at 16:12
I've installed openssl and I'm not getting any errors, but this thing doens't look like a SHA1 fingerprint http://i.imgur.com/Qp26eNh.jpg any suggestions? – arsena Dec 19 '14 at 19:22
That is a base64 encoded version of a binary encoded sha1 – der_michael Dec 22 '14 at 18:33
If you want to see just the shah run keytool -exportcert -alias androiddebugkey -keystore ~/.local/share/Xamarin/Mono\ for\ Android/debug.keystore | openssl sha1 – der_michael Dec 22 '14 at 18:33
Thanks again for your attention. This is what I got so far: http://i.imgur.com/lr6XA8S.png Sorry for asking too much questions but i really need to get this done. Thanks again – arsena Dec 23 '14 at 13:49
Insert a colon after every other character and capitalize all lower case letters maybe? – der_michael Dec 23 '14 at 18:43
That worked, google dev. console generated new api key. I haven't tested it yet but I think there's nothing else to ask. Thanks for your help! – arsena Dec 25 '14 at 07:43
