Next generation iOS and Android apps for Mattermost in React Native

Last update: Aug 11, 2022

Mattermost Mobile

  • Minimum Server versions: Current ESR version (5.37.0)
  • Supported iOS versions: 11+
  • Supported Android versions: 7.0+

Mattermost is an open source Slack-alternative used by thousands of companies around the world in 14 languages. Learn more at https://about.mattermost.com.

You can download our apps from the App Store or Google Play Store, or build them yourself.

We plan on releasing monthly updates with new features - check the changelog for what features are currently supported!

Important: If you self-compile the Mattermost Mobile apps you also need to deploy your own Mattermost Push Notification Service.

Frequently Asked Questions

How is data handled on mobile devices after a user account is deactivated?

App data is wiped from the device when a user logs out of the app. If the user is logged in when the account is deactivated, then within one minute the system logs the user out, and as a result all app data is wiped from the device.

Can I connect to multiple Mattermost servers using the mobile apps?

At the moment, we only support connecting to one server at a time. If you need to connect to multiple servers, please upvote the feature request so we can track demand for it.

As a work around, you can install both the released "Mattermost" app and sign up to be a tester for the "Mattermost Beta" app so you can connect to two servers at once.

Will there be second generation apps available for tablets?

We plan to add support for tablets in the future, but the timeline depends on how many people have a need for it. If you're looking for a tablet version, please help us out by upvoting the feature request!

Troubleshooting

I keep getting a message "Cannot connect to the server. Please check your server URL and internet connection."

This sometimes appears when there is an issue with the SSL certificate configuration.

To check that your SSL certificate is set up correctly, test the SSL certificate by visiting a site such as https://www.ssllabs.com/ssltest/index.html. If there’s an error about the missing chain or certificate path, there is likely an intermediate certificate missing that needs to be included.

Please note that the apps cannot connect to servers with self-signed certificates, consider using Let's Encrypt instead.

I see a “Connecting…” bar that does not go away

If your app is working properly, you should see a grey “Connecting…” bar that clears or says “Connected” after the app reconnects.

If you are seeing this message all the time, and your internet connection seems fine:

Ask your server administrator if the server uses NGINX or another webserver as a reverse proxy. If so, they should check that it is configured correctly for supporting the websocket connection for APIv4 endpoints.

  • 1. MM-28474: Custom Sidebar Categories

    Summary

    This PR allows the user to see their "custom" categories in the sidebar; bringing the mobile app further inline with the web/desktop clients.

    It also respects the EnableLegacySidebar setting - when enabled, it displays the existing sidebar. For server versions less than or equal to 5.31.0, the ExperimentalSidebarCategories displays the new sidebar.

    Currently UnreadsOnTop is permanently set to true but can now be used to follow user preferences on the mobile app.

    To-Do
    • [x] Unable to create channels in categories via the latest build
    • [x] "More unreads" banner always visible
    • [x] Category collapsing multiple triggers
    • [x] Sort order not respecting user pref on mobile

  • 3. [MM-23761] [MM-25766] Add "More Messages" button

    Summary

    This PR removes auto-scrolling to the new message line on channel load and adds a "More Messages" button when there are unread posts. The unread post count is calculated on channel switch from the difference channel.total_msg_count - member.msg_count and with the addition of any inserted non-message posts (ie, date line) by makePreparePostIdsForPostList. On press of the button the user is scrolled to the index of the new message line or to the index of the highestMeasuredFrameIndex if the new message line post has not yet been measured. If there are no more unread messages the button is hidden, otherwise the unread count is updated and pressing again will scroll to the updated index of the new message line or the next highestMeasuredFrameIndex.

    Because we don't want a new message line to be added when a user submits their own post either in the current channel or in another channel from separate client, there was a previous condition added in makeFilterPostsAndAddSeparators to not add the new message line if the post's user_id is the current user's ID. This was problematic for this feature as the index of the final new message line would not coincide with the index of the last unread message and so in this case the "More Messages" button would never hide. To get around this I added an ownPost property to Post. When RECEIVED_POST or RECEIVED_NEW_POST actions are handled, if the post is the current user's post then the channel's lastChannelViewTime is updated to be the post's created_at value + 1, ensuring that the new message line is not added since the existing condition post.create_at > lastViewedAt will be false.

  • 4. App is low on fps on new upgrade to android 11

    Summary

    Since upgrading my S20 plus to the new android 11 update, the app appears to perform super slow. I have also attached a view, and the low fps you will see is not from the recording, but from only the mattermost app.

    Environment Information

    • Device Name: Samsung Galaxy S20 Plus
    • OS Version: Android 11
    • Mattermost App Version: 1.38.0
    • Mattermost Server Version: 5.26.0

    Steps to reproduce

    Have an S20 with the latest update, install mattermost app and try to use anything, you will notice the sluggish behaviour

    Expected behavior

    Before the upgrade, the app used to work very fast and was performing well.

    Observed behavior

    Doesn't matter which channel or team, once I open the app every thing is very low performance Video the online preview makes it a bit hard to see the difference, try to download the file to best see the issue

    Possible fixes

    If you can, link to the line of code that might be responsible for the problem.

  • 5. [MM-11947] Adds dark mode to server select & login

    Summary

    Adds dark and light themes to server select, login options, and login screen.

    I couldn't find all the colours listed in the mock, so I just used the Digital Color Meter to get the approximate colours and created a colours file to keep them all together and hopefully simplify the scheme. If you'd like to change the the colours to use opacities instead, could you please describe the new colours relative to app/styles/colors.js?

    Instead of updating the theme, which has different keys from the ones needed for these few pages, I created objects filled with colours for light and dark schemes in app/styles/colors.js. In the future, maybe these can be integrated with themes, but I don't know enough about the themes to do that yet.

    There's a lot to be updated still! I could really use some fresh eyes and expertise to finish this up. Thanks in advance!

  • 7. iOS build issues with signing

    Summary

    I think the iOS build process does not always take into account the variables from .env file for the signing part. I have an error during signing, since the build is trying to use the default profile instead of mine.

    Environment Information

    I'm using macOS Sierra, latest version of Fastlane (2.85.0) and I cloned the project at this commit : https://github.com/mattermost/mattermost-mobile/commit/1f7ec077860a040e23303481d086939b90e60f75

    Observed behavior

    When I want to build the app, the process will fail when signing with these errors :

    [16:05:47]: ▸ Code Signing Error: Provisioning profile "iOS Team Provisioning Profile: *" doesn't include signing certificate "iPhone Developer: Nicolas furno (********)".
    [16:05:47]: ▸ Code Signing Error: Provisioning profile "iOS Team Provisioning Profile: *" doesn't support the App Groups capability.
    [16:05:47]: ▸ Code Signing Error: Provisioning profile "iOS Team Provisioning Profile: *" doesn't support the group.******.mattermost App Group.
    [16:05:47]: ▸ Code Signing Error: Provisioning profile "iOS Team Provisioning Profile: *" doesn't include the com.apple.security.application-groups entitlement.
    [16:05:47]: ▸ Code Signing Error: Code signing is required for product type 'App Extension' in SDK 'iOS 11.2'
    

    When opening the project in Xcode just after these error, here's what I noticed : the default app ID is used, instead of the one I used in my .env file.

    capture d ecran 2018-03-19 a 16 09 16

    If I edit manually the project.pbxproj file to search all default values and replace these with mine, the build is working fine.

    I guess there is a bug somewhere, that prevents the build process to extract the correct values during the build ?

    Let me know if you need more information.
