Ag App Central Submission Guidelines
Developing Android Apps to Run on the TMX-2050, GFX-750 and GFX-350 Displays
In order to provide the best possible experience for users of the Trimble® TMX-2050™, GFX-750 and GFX-350 displays, and your new mobile application, Trimble has created a list of development and testing procedures that must be followed before you may publish your new app in Trimble Ag App Central.
This page will help you understand the publishing process for Android-based mobile applications and prepare for a successful product launch with Trimble. It will also summarize the tasks you'll need to complete before publishing your app on Trimble Ag App Central, such as creating a signed, release-ready application package (APK) and creating the product page and graphic assets to promote your app.
As you move through the development and publishing processes, a variety of support resources are available to assist you. Relevant links are provided with each step.
To submit all items, please visit Ag App Central Content and Upload APK, to submit the following:
Note: At this time, Trimble Ag App Central handles only the listing and download of mobile applications and does not allow for direct licensing and e-commerce purchase of apps from third-parties. However, you may choose to monetize your app’s functionality and charge for its use in whatever currency appropriate for each transaction. All licensing, subscription and/or monetary transactions must be handled directly between you (the developer) and the end-user.
