title: Simulating GPS Data to Android AVD Not Working
body: <p>I’m hoping someone can help me with an issue I’m having with sending emulated GPS data to an Android AVD in Eclipse. If I run the application on a real device everything works fine, but when I attempt to uses the built in emulator in eclipse nothing will happen. I have also tried telneting into the AVD and issuing the geo fix command. Below is the code I am using although I don’t think there is anything wrong with it if it works on the real device</p>
  
  <p>The manifest file</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="net.TestGoogleMaps"

      &lt;uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"&gt;&lt;/uses-permission&gt;  
      &lt;uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"&gt;&lt;/uses-permission&gt;  
  &lt;uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" /&gt;
  
  &lt;application
      android:icon="@drawable/ic_launcher"
      android:label="@string/app_name" &gt;
      &lt;activity
          android:name=".TestingGoogleMapsActivity"
          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;/application&gt;
  &lt;/manifest&gt;

  <p>I will also get the following error sometimes when simulating the GPS data from eclipse to the device in the LogCat tab of eclipse.</p>
