A workaround of 'file not found` on admob and gcm

[ikuo]

When I run mvn install with android studio environment (after completing android update sdk -u), I get the following errors:

$ mvn install
... (snip) ...
[ERROR] Failed to execute goal org.codehaus.mojo:properties-maven-plugin:1.0-alpha-2:read-project-properties (default) on project admob: Properties file not found: /usr/local/android-studio/sdk/extras/google/admob_ads_sdk/source.properties -> [Help 1]

$ mvn install
... (snip) ...
[ERROR] Failed to execute goal org.codehaus.mojo:properties-maven-plugin:1.0-alpha-2:read-project-properties (default) on project gcm-client: Properties file not found: /usr/local/android-studio/sdk/extras/google/gcm/source.properties -> [Help 1]

And the directories admob_ads_sdk/ and gcm/ are missing in the sdk directory:

$ ls -alF /usr/local/android-studio/sdk/extras/google

Although I'm not sure that it is the right solution, mvn install succeeded against the rest of android library after making changes of this pull-request.

That is not an acceptable solution. We need to support GCM and Admob.
