On the screenshot you shared I do not see an Android folder. Please make sure that the person who has a licensed account to download a developer version of UI for Android has sent you the product files. The licensed installation can be either Telerik_UI_for_Android_2014_3_1403_DEV.zip or Telerik_UI_for_Android_2014_3_1403_Dev.msi. You can use both files to obtain the licensed developer .aar files. Just replace the trial .aar files in your project with the developer .aar files.
Give it a try and let me know how it goes.
