Google Maps API V2 - always get authentication error

Google Maps API V2 - always get authentication error

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 at all!

Not with the demo project, com.example.mapdemo, not with my own project.

I definitely have my debug.keystore SHA1 fingerprint registered, now for both my app and com.example - I also tried the browser API key where everybody says that would work, too.

BUT NO.

I always get:

06-16 11:21:29.860: E/Google Maps Android API(2382): Authorization failure.  Please see https://developers.google.com/maps/documentation/android/start for how to correctly set up the map.  

I am getting REALLY, REALLY mad at this. How is it possible to NOT completely and thoroughly describe this matter so that people that are otherwise able to program Android apps, can follow and succeed??

HOW?

Could anybody please tell me what else could be wrong?

Add-on: I set up everything exactly according to the specs, got my key from my debug.keystore, tried it with com.example for the maps demo, with my own package for my app. Does not work. Plus: that silly empty window. How on earth is that gonna work... :-(

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 ?

I am also having the same issue and know I kinda know what causes the problem ( not the solution to it though -yet- )

Try to run your app of other phone than your HTC One. Because I have the issue with my HTC One but when I run it on my S3, it runs perfectly.

Try and let me know please

EDIT

I solved it. But not sure what was the exact solution but here what I did as steps: 1- I displayed the developers options in the phone settings use the 7 times clicks in 4.2 OS 2- Allowed Mock Location 3- Selected my app in the "select debug app" 4- uninstalled my app 5- re-installed it 6- run it and waited for 30 seconds then the maps showed

Hope this helps

I had got same issue. After checking 20th time the steps from ddewaele's answer, turning on the Maps V2 android in Google's API console, I have restarted my phone, waited ~15s for data to download and all works like a charm. Uninstalling application was not enough to get it working. Just leaving info for other map using devs on the edge.

Even I was facing the same issue for days. I simply uninstalled the app from settings, reinstalled it and magically it worked.
