Ag Apps & App Central
Submission guidelines
Use the information below to better understand the publishing process for Android™-based mobile applications and to prepare for a successful Ag App launch through Trimble’s App Central.
Step 1
Review developer policies & agreements

In order to download Trimble’s Android Software Development Kit (SDK) or submit an app for publishing on Trimble’s App Central, developers must first read and agree to Trimble’s developer software policies and agreements.

Relevant documentation is provided for review by clicking on the links below, including both webpage and downloadable PDF versions. Agreement will be provided when the developer submits relevant materials or requests the SDK.

Step 2
Review launch checklist

Developers wishing to submit an Ag App to Trimble’s App Central should start by downloading Google’s Android Developers Launch Checklist, which serves as a basis for best practices.

Note: The following are not required for Trimble’s Android-based displays:

  • Determining a content rating for your application
  • Using in-app billing
  • Completing a store listing for App Central
  • Using Google Play badges and links

Additional details can be found by requesting and downloading Trimble’s Android SDK.

Step 3
Develop your app

App development should be done in accordance with Android and Trimble guidelines, as highlighted in the previous step and the Trimble Android SDK.

Note: If your application requires a user to log in, developers should create credentials for a test account that can be used by Trimble to test your app. This information will be submitted as part of Steps 4 and 5, including:

  • Providing an unlock code or instructions for obtaining an unlock
  • Providing details and directions in the app’s general description section if the app requires a purchase to obtain the unlock
Step 4
Submit app files or ideas

Below is an overview of the information you will need to provide with your submission:

Basic Details

Provide your name, email address, company name and phone number.

App Request and Purpose

Describe what your application can do and what you are trying to achieve.

Hardware Platform

Select the Trimble display(s) that your app will be available on. Choices include:

  • TMX-2050 display
  • XCN-2050 display
  • GFX-750 display
  • XCN-1050 display
  • GFX-350 display
  • XCN-750 display

User Benefits

Describe how the customer (i.e., the farmer) and the Trimble reseller can benefit from adding this functionality to their Trimble display.

Supporting Information and Materials

Provide input on when you would like your app to be available in the App Central marketplace, whether or not your app can run without Google Mobile Services, details about unlocking features for testing (as mentioned in Step 3) and relevant files.

Step 5
Submit App Central listing information

Much like in the Google Play store, App Central requires a brief description of your app describing key features and benefits for the farmer. Below is an overview of the items and information you will need to provide.


A maximum of 150 characters overviewing your app and grabbing users’ attention.


A maximum of 500 characters explaining any additional licensing purchases needed for full functionality of your app, website or contact information where licenses can be purchased and license prices (if applicable).

What’s New

A brief description of new features or functionality (only submitted when providing an update to apps already installed in App Central).


Apps in App Central may be open to all regions or have limited availability based on geography. Regions include:

  • All Regions
  • Europe
  • North America
  • Northern Latin America
  • Southern Latin America
  • China
  • Japan
  • CIS (former USSR)
  • North Africa
  • Central/South Africa
  • Central Asia
  • South Asia
  • South East Asia

Screenshots help potential users understand the key features and functions of your app. Consider the following factors when submitting screenshots for display in App Central:

  • Your app will be allowed a minimum of three (3) screenshots and a maximum of six (6) screenshots
  • Screenshots must be provided as .jpeg or 24-bit .png files (no alpha)
  • Screenshot dimensions cannot exceed 1024 pixels x 576 pixels with a 16:9 ratio

Note: Screenshots for your app may be used in promotional or marketing materials for Trimble displays.

Application Icon

Your app icon is essential for helping your app get recognized and used in the field – so make sure it is eye-catching! The image you submit to Trimble for use as your app’s launch icon must be the same image you submit in the final APK file. Below are the image requirements:

  • Must be submitted as high-resolution images (32-bit .png files are preferred)
  • Dimensions must be 512 pixels x 512 pixels and cannot exceed 200 KB in size
  • Third-party applications may not use the Trimble logo

Note: App icons may be used in promotional or marketing materials for Trimble displays.

Featured App Imagery

From time to time, Trimble will highlight certain applications with “Featured App” status in App Central. This status gives your app additional exposure to end customers worldwide or by specific region.

To be considered for “Featured App” status in App Central, you must submit an additional 1024 pixels x 500 pixels image to display alongside your app description. Here are some best practices to consider:

  • Make your graphic interesting
  • Use colors that stand out
  • Do not promote your brand
  • Localize images as needed for different languages
  • Do not use a text-heavy advertising style graphic
  • Do not use transparency
