An update to the issue is:

We have tried it on Physical device Google Nexus 4.1.2 and Google API-10's Emulator.
Comment 2 PJ 2013-07-01 13:38:14 UTC
Peter can you check on the regression status here and talk to Eno about it? I'm not sure if there's a new Google Play Library involved with the regression status report of 'Not a regression'.
Comment 4 Prashant manu 2013-07-04 09:45:58 UTC
Today I have checked this issue with following builds:

All Mac
X.S 4.0.9(build 12)
Mono 3.0.12
Xamarin.Android 4.7.11-2-1

And we have added docs folder and project.properties as a link in GooglePlayServices project and then we have run the project on GoogleAPI-17 emulator and we are still getting exception. Please view the screencast of Project which having docs on Project.properties: http://screencast.com/t/vykKU63R8BDU

Hence reopening this issue
Comment 5 Peter Collins 2013-07-08 17:35:19 UTC
This exception seems to be occurring when the google_play_services_lib project has not been updated and built with ant. Please attempt to build the Google Play Services binaries the following instructions before building the GooglePlayServicesTest sample.

>Build the Google Play Services SDK binaries, using eclipse or ant. The library is located at: >$(ANDROID_SDK)/extras/google/google_play_services/libproject/google-play-services_lib.

>Run the following in the directory mentioned above to build with ant:
>   $(ANDROID_SDK)/tools/android update project -p .
>   ant debug

After building the google play services binaries, properly linking the required files and updating the API Key I am unable to reproduce the issue mentioned above.
Comment 6 Peter Collins 2013-07-08 17:36:19 UTC
Build instructions ran over by mistake, reposting better format:

>Build the Google Play Services SDK binaries, using eclipse or ant. The library is located at:


>Run the following in the directory mentioned above to build with ant:
>   $(ANDROID_SDK)/tools/android update project -p .
>   ant debug
Comment 8 Nischal 2013-07-11 04:39:04 UTC
Today I have checked this issue with following builds

X.S 4.0.9(build 9)
Mono 3.1.1-2
Xamarin.Android 4.8.0-1

We have followed the comment which are mentioned in comment#6 and then we observed that build.xml file is missing form GooglePlayServices/libs/google-play-services, first we have created build.xml file using command   "Desktop/android-sdk-macosx/tools/android update project -p Desktop/android-sdk-macosx/extras/google/google_play_services/libproject/google-play-services_lib/"

And then we have build and debug the Google_Play_Services/libs/google_play_services using ant this is the gist for the same: https://gist.github.com/atin360/d07a4915d72a90102e73 after that we open the GooglePlayServices in XS and added file and folder in GooglePlayServices Project as a link and then we run the project on device. Now application working fine and we are successfully able to open map after clicking on Basic Map and successfully able to open Drag Melbourne after clicking on Markers.

Device info:
Galaxy S4 version 4.2.2
HTC one version 4.0.4

Now closing this issue.
