Android HelloGoogleMaps tutorial exception

Question

I'm working with the HelloGoogleMaps tutorial on the Android Developers' Resource page (http://developer.android.com/resources/tutorials/views/hello-mapview.html) and when I run part 1 of the application ("Creating a Map Activity") on my emulator, I get the message "The application HelloGoogleMaps (process com.example) has stopped unexpectedly. Please try again." I'm pretty sure that I followed all of the instructions correctly, however I'm not sure that I set up my emulator environment correctly. Can anyone please help me figure out what's going on? Thanks.

Here's the output from logcat:

Answer 1

Hi I am not sure if you are having the same problem as I had but make sure your maps and internet permission in your manifest are within the Activity brackets not the manifest i.e:

  </activity>
    <uses-library android:name="com.google.android.maps" />
   <uses-permission android:name="android.permission.INTERNET" />

<activity android:name=".champ" android:label="@string/app_name"

android:theme="@android:style/Theme.NoTitleBar">

You will also need to set up a new AVD that uses the same Google APIs deployment target

Have you done that?
