Google Maps API V2 - always get authentication error

Question

I found lots of questions regarding this - and I am almost ashamed to ask it myself.

But no matter how hard I try, I simple do not get the Maps API running

Answer 1

Assuming

• you are trying this on a device that has access to Google Play Services
• you have linked your project with the Google Play Services library
• you have setup the necessary permissions like this:

snippet from manifest:

• you have setup the map key like this :

• you have put the meta-data tag inside the application tag

• you made sure that you are building the APK with the correct keystore (corresponding to the one defined in the API console).

• you removed and redeployed your application completely after checking / updating these steps you should be good to go.

From my experience I was able to follow the instructions on Google Maps Android API v2 Getting started, but I do recall having to completely undeploy and redeploy the app again after playing around with the API keys / permissions.

On what device are you running ?
