Question

I am attempting to create a MapView application following the tutorial from the Android website here. I have got everything set up and the map displays but with empty tiles!

The API key I’m using is generated from the debug.keystore located in “C:\Users\Pete\.android” and all of the correct permissions are set up in the manifest. The maps library is also in the manifest but it still doesn’t work. I have tried creating a new debug keystore and placed it in the same folder (obviously also generating a new API key) and still no luck.

Your manifest file needs some reshuffling:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.stringerapps.testing.gps"
        android:versionCode="1"
        android:versionName="1.0">
   <uses-sdk android:minSdkVersion="8" />

     <!-- permissions -->
     <uses-permission
         android:name="android.permission.INTERNET">
     </uses-permission>
     <uses-permission
         android:name="android.permission.ACCESS_FINE_LOCATION">
     </uses-permission>
   <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".Home"
              android:label="@string/app_name">
             <intent-filter>
                 <action android:name="android.intent.action.MAIN" />
                 <category android:name="android.intent.category.LAUNCHER" />
             </intent-filter>
        </activity>

     <!-- import the library com.google.android.maps!!! -->
     <uses-library android:name="com.google.android.maps" />


    </application>
</manifest>

Try that and I’ll look through your other files to see if I can find anything else.
