Newbie Including Google Maps in 1st App

Hi All, I have created my first app and all looks good. I am trying to get a map but I have 1 of 2 problems. Either it just displays a blank white page. I have realised that this is because I am missing my API key. I have generated one with Google and added it to the AndroidManifest.xml in <meta-data android:name="com.google.android.maps.v2.API_KEY">. Now when I launch the app, it crashes when I load the map page. I have seen reference to changing the API from 21 to 14 but this also does not seem to help. Also I am unable to look up Long and Lat on the Location Map screen setup page. Whatever I enter in to the Sub-Title, when I tab out it says "working..." but never finds the Latitude & Longitude values. Sorry if this is something I am missing, David

Sometimes you can see something and go 'ah ha', and know what to say. Other times need more information. This is one of those times. ;) 1) If you're using the Android 'Virtual Device' (aka a Simulator) Maps don't show. Ever. You'll need a real device. 2) When it 'crashes' the logcat spews a million lines of stuff, mostly red. What you'll want to do is scroll up to where the 'black meets the red' and that's where you'll find what it was trying to do when it crashed. Those are the log entries we'll want to see. It could explain a few things. 3) Changing the API from 21 to 14 may not matter. It matters only to the target device. 4) I live on Guam, so the 'address to coordinate' algorithm never works for me anyway. I tend to go to sites such as http://itouchmap.com/latlong.html to get my coordinates. Let us know what the log says, and we'll have a better idea of what to look for. Cheers! -- Smug
