 <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/mainlayout" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <com.google.android.maps.MapView android:id="@+id/mapview" android:layout_width="fill_parent" android:layout_height="fill_parent" android:clickable="true" android:apiKey="0f724slL07SJV93E_oZAPQDt54ewoD-PD7zTmDw" /> </RelativeLayot>

My computer has two hard drives, my code is stored on one hard drive, and java jdk and eclipse on another hard drive, can this be the cause of this problem?

ApiKey differs from debug collections and releases. Did you provide a fingerprint of your keystore to the site? If so, you also need to do this for the debug repository.

I think this is a problem with your api key ... Google Maps API

My manifest is .xml ..... do you see the differences?

 <com.google.android.maps.MapView android:layout_width="fill_parent" android:layout_height="fill_parent" android:apiKey="XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX" />
