Develop Reference

I'm attempting to make an app that displays current location but the app won't display the map

I'm new to coding and especially android development.I've made a simple calculator app for a start and it worked,my app doesn't display the map at all.I've been working on this for two days now but still can't figure out the problem.Please do tell me where I'm standing and where the problem is.
Please refer to the screenshot.

I corrected the speeling (bustrafic-->bustraffic) in the screenshoot of Simple API access but it didnt help.
I appreciate any help.

It works now I have just restarted eclipse.

Trying to figure out how Google Maps integrate with Android and Eclipse, I followed the documentation and did what I was supposed to, but I keep getting the error mentioned in the title, saying that the value isn't right, it is expecting 5089000, but is getting 0, presumably from the line
android:name="com.google.gms.version"
android:value="#integer/google_play_services_version" />
Googling this error, I've found out that most people forgot this meta-data tag, but as you can see, I put it where it's supposed to be, and I've also imported the proper library and included it in the project, but I'm still getting the error.
Anything else that might be causing this?
I've got the proper API key generated, I've downloaded Google Play Services via SDK and I don't see that I've missed any steps.

I believe it should be
android:name="com.google.android.gms.version"
not
android:name="com.google.gms.version"

problem solved.. i had to uninstall the app, and do a project clean, then re-install the app.. don't know why exactly but now its working

Your API key in your manifest clearly does not match the API key you posted that is showing in the API console. Paste the API key from the console into the manifest. Should fix you right up.

Changing API Key Has No Effect

In messing around, I noticed that adding a dummy API Key to a working project's AndroidManifest.xml does not affect the project. In fact, I added key "Asfasdfasdfasfa" which isn't even valid and the project continues working.
Could someone draw light on this issue? Is there caching going?

Take a look of this: Can I have a single Google Maps API key for all my apps without registering their package names?.
To create an API key, you provide some information that include the package name of the app. That means you are trying to validate one of your apps with a key created with another package name, this could be the issue.
