Google Maps Display in Android: +/- symbols visible, no map -

for reason, have google maps application attempting run, gives me grey screen , +/- options map.

i've used 2 guides extensively, , continue have same problem. i've googled extensively, , seems issue must api console or dependencies, , i've included screenshots of those: must noted storing these files in folder syncs dropbox - don't know if that's bad thing or not.

when export android application, i'm using keystore made, , alias made. doing because trying run on phone opposed emulator (because i've heard play isn't working emulators). i'm extracting so:

and finally, here's console:

here's manifest:

    <uses-sdk         android:minsdkversion="13"         android:targetsdkversion="17" />      <permission     android:name="com.hotspotprime.permission.maps_receive"     android:protectionlevel="signature" />     <uses-permission android:name="com.hotspotprime.permission.maps_receive"/>     <uses-permission android:name="android.permission.internet" />     <uses-permission android:name="android.permission.access_network_state" />     <uses-permission android:name="android.permission.write_external_storage" />     <uses-permission android:name="com.google.android.providers.gsf.permission.read_gservices" />     <uses-permission android:name="android.permission.access_coarse_location" />     <uses-permission android:name="android.permission.access_fine_location" />     <uses-feature     android:glesversion="0x00020000"     android:required="true"/>     <application         android:allowbackup="true"         android:icon="@drawable/ic_launcher"         android:label="@string/app_name"         android:theme="@style/apptheme" >         <activity             android:name="com.hotspotprime.mainactivity"             android:label="@string/app_name" >             <intent-filter>                 <action android:name="android.intent.action.main" />                  <category android:name="android.intent.category.launcher" />             </intent-filter>         </activity>          <meta-data     android:name="com.google.android.maps.v2.api_key"     android:value="aizasydqvfq7czrpttmrqg3k_ih7jt-vsgfjncy" />     </application>  </manifest> 

code: package com.hotspotprime;

import android.os.bundle; import android.support.v4.app.fragmentactivity;  public class mainactivity extends fragmentactivity {      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);     } }
