Google maps v2 not displayed

Question

I have been trying to run the sample project of the new Google maps V2 API

And a blank screen is shown.

The question is why is it not showing the map on a 2.2 device, on the stacktrace I see the following message:

  12-06 09:40:36.707: E/Google Maps Android API(14657): Google Maps application is missing.

Edit: well it seems like we can't run it yet on the emulator, yet.

Answer 1

The logcat saw the following message:

12-06 09:40:36.707: E/Google Maps Android API(14657): Google Maps application is missing.

So Installing Google Maps has solved the problem.

Also it Seems like the google maps installation is blocked in some countries, and running the application on 2.2 simply won't work without the google maps installed.

From the comment a user has posted a code to check if google maps is installed in the following question:

Google Maps Android API V2 check if GoogleMaps are installed on device

Answer 2

I am yet to test this, but I am going to assume you need the google play services on your device, check for following on your device:

If this is missing I have a feeling that the new GMS will not work, as your emulator has no google maps OR google play services this will stop it working as it can't find the package.

From the looks of it, GMS fails silently on a real device instead of crashing like the emulator.

Manually install Google Play Services on your device and try again.

Answer 3

I've had similar problem. After installing (and later uninstalling) Google Maps, everything settled down.

Answer 4

Make sure to include a call to:

GooglePlayServicesUtil.getOpenSourceSoftwareLicenseInfo

somewhere in your application (i.e. about section). I had the same problem until I used this.

(I understand this post is a month old and the user may have moved on in development, however others may benefit from this bit of info as I did)
