.NET for Android error XA4235
error XA4235: Maven artifact specification 'com.example' is invalid. The correct format is 'group_id:artifact_id'.
The specified Maven artifact specification is invalid.
For example the following item uses a comma separator instead of a colon:
<ItemGroup>
<AndroidMavenLibrary Include="com.example,mylib" Version="1.0.0" />
</ItemGroup>
To resolve this error, ensure that the artifact specification is of the form 'group_id:artifact_id':
<ItemGroup>
<AndroidMavenLibrary Include="com.example:mylib" Version="1.0.0" />
</ItemGroup>
