ODK Collect is an Android app for filling out forms. It is designed to be used in resource-constrained environments with challenges such as unreliable connectivity or power infrastructure. ODK Collect is part of Open Data Kit (ODK), a free and open-source set of tools which help organizations author, field, and manage mobile data collection solutions. Learn more about the Open Data Kit project and its history here and read about example ODK deployments here.
ODK Collect renders forms that are compliant with the ODK XForms standard, a subset of the XForms 1.1 standard with some extensions. The form parsing is done by the JavaRosa library which Collect includes as a jar.

New versions of ODK Collect are released on the last Sunday of each month. We freeze commits to the master branch on the preceding Wednesday (except for bug fixes).
-
Make or get (example forms, test forms) an XLSForm.
-
Convert the XLSForm (xlsx) to XForm (xml). Use the ODK website or XLSForm Offline or pyxform.
-
Once you have the XForm, use adb to push the form to your device (after enabling USB debugging) or emulator.
adb push my_form.xml /sdcard/odk/forms/ -
Launch ODK Collect and tap
Fill Blank Form. The new form will be there.
-
Download and install Git and add it to your PATH
-
Download and install Android Studio
-
Fork the collect project (why and how to fork)
-
Clone your fork of the project locally. At the command line:
git clone https://github.com/YOUR-GITHUB-USERNAME/collect
If you prefer not to use the command line, you can use Android Studio to create a new project from version control using https://github.com/YOUR-GITHUB-USERNAME/collect.
- Open the project in the folder of your clone from Android Studio. To run the project, click on the green arrow at the top of the screen. The emulator is very slow so we generally recommend using a physical device when possible.
To run functionality that makes API calls from your debug-signed builds, you may need to get an API key or otherwise authorize your app.
Google Drive API - Follow the instructions in the "Generate the signing certificate fingerprint and register your application" section from here. Enable the Google Drive API here.
Google Maps API - Follow the instructions here. Please be sure not to commit your personal API key to a branch that you will submit a pull request for.
