title: MapView Issues / Empty Tiles
body: <p>I'm having issues with a MapView.. I've used MapView's before so I really don't know what the problem is, it's probably something simple that I'm overlooking but it's driving me insane. The app installs and runs fun, but the MapView tiles do no load. All I see is an empty grid. I know the API key (debug keystore) is fun because I have another project using it that works perfectly. I've included my manifest, layout, and activity files to help diagnose the problem. I'd appreciate any help - I'm baffled!</p>
  
  <p>manifest:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;

      &lt;uses-library android:name="com.google.android.maps" /&gt;
      &lt;activity
          android:name=".StudyBuddy"
          android:label="@string/app_name" &gt;
          &lt;intent-filter&gt;
              &lt;action android:name="android.intent.action.MAIN" /&gt;
              &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
          &lt;/intent-filter&gt;
      &lt;/activity&gt;
      &lt;activity
          android:name=".MapInterface" &gt;
      &lt;/activity&gt;
      &lt;service
          android:name=".FriendService" &gt;
          &lt;intent-filter&gt;
              &lt;action
                  android:name="com.***.studybuddy.FriendService" /&gt;
          &lt;/intent-filter&gt;
      &lt;/service&gt;
  &lt;/application&gt;
