As announced in February, this year we are gradually stopping the support and maintenance of the old Android Apps.
By the end of June we will be stopping Event Capture and Tracker Capture. After that, they will be available in Google Play and Github, but we will not follow up the related Jira project and we will not be fixing bugs.
The new & improved DHIS2 Capture Android app supports tracker and event programs, extends the functionality of the old apps and is compatible with 2.30 - 2.34 (and has no breaking changes with 2.29).
We encourage you to check it out and test it on your server.
To prevent any problems when making the switch to the new app, please consult this paragraph in the documentation: Migrating from the old apps.
