Troubleshooting for the Android app

If something seems to be going wrong on the app, the first step to try is to close the app completely and then re-open it. To close the app this, tap on your device's app manager, and swipe to close the Trello app.

If the problem continues after closing and re-opening the app, there are a few things you can try to fix the problem: clearing the cache, logging out of the app and back in, or reinstalling the app.

WARNING: These actions will clear any offline changes you've made to your boards that haven't been synced yet, so make sure to check for unsent changes before proceeding further.

Check for unsent changes first!

If you've made changes to your boards while offline, the troubleshooting steps described further down will prevent these changes from being synced. Fortunately, there are a few different ways to check to see if you have any unsent changes. You can also check for sync indicators (circular arrows) on boards in the home screen and on cards, like in the screenshot below:

2. Finally, you can go to the Sync Queue in settings menu and check to see if it has items in it that aren’t errors (if they're errors, they'll have red text beneath).

What to do if you have unsent changes

If you see any of these indications that you have unsent changes, clearing the cache, logging out and back in, or reinstalling the app will cause you to lose these changes. To prevent this, the best course of action is to get back on a network so that the changes will sync.

If that doesn't work at first, try closing the app completely by tapping on the home screen and swiping up on Trello, and then reopening Trello. If the changes still don't sync after that, check to make sure that the network is working by opening a webpage in your browser.

If you're not able to get on a network, or if the changes don't send for some reason, you can export a list of the changes so that you can redo them later if they're lost. To do this, open the app and go to the Account tab. From there, open the Sync Queue. Tap on the share button to send yourself a text description of the changes.

Troubleshooting after checking for unsent changes

After you've confirmed that you don't have any unsent changes, or after you've exported the Sync Queue as a backup, you can safely continue with the troubleshooting steps below.

Clearing the cache

Sometimes, cached data in the Android app will cause your Android device to be out of sync with the web interface.

To clear that, open your phone's Settings app, then go to 'Apps' and scroll down until you see the Trello app listed. Tap on Trello, and then tap on 'Storage'. Finally, tap on "Clear Cache".

Logging out of the app and back in

If clearing the cache doesn’t help, you may want to try logging out of the app and back in. To log out, first open the Trello app and tap on the Account tab from your main home screen (this will be in the bottom right on the iPhone or the top left on the iPad). From here, you can select “Log Out”.

If you've made offline changes that haven't been synced yet, you'll see the following warning when you try to log out.

In this case, try to get back to a network so that your changes will be synced before logging out, so that you don't lose these changes.

Once you’ve logged out, select “Log In” to sign in to Trello again. 

Reinstalling the app

If the problem persists, you can also reinstall the app. Delete the app from the device, and reinstall it from the Android Play Store. You’ll need to log in again. If you purchased Trello Gold on your phone previously, you’ll still have access to this once you log in.
