The Android app requires the Google Play Services because it uses GCM for push notifications. This library is not open-source so it prevents Mattermost from being included in FOSS repositories like F-Droid.
It would be nice to have an option that builds the app without GCM.

We need a MSI file for automated (silent) installation. That way you can deploy the application with the group policy of windows.

Allow to share current location and display locations with a preview map

Currently, whenever a mobile notification is received, it displays the message in the notification, but accessing the notification from a wearable (Android Wear, Tizen, Pebble, etc.) only gives the option to show on phone, with no choice to reply to the message from the notification. It would be nice to have notification replies so that people with wearables can respond to messages quickly without needing to pull out their phone.

Actually having a mattermost instance connected to gitlab that use omniauth providers (in my case saml, github and google) is not compatible with the android client.

As it's working on IOS, I suggest that you evolve the android client to make it compatible.

From what I observe, the saml token is being truncated

Ability to configure the Enter key behavior: submit the message you are writing instead of create a new line when you press the enter key (it's useful for example if you are using an external keyboard)

Google Play Services and GCM is blocked in China. This means that users that are not on VPN cannot get push notifications. The only known workarounds that I know of are using a 3rd party Push Notification service such as Baidu (http://push.baidu.com/doc/android/api) or Pushy (https://pushy.me/) or to run your own push notification service. I wish I didn't have to make this suggestion, but MatterMost is severely crippled by this and I dont see the geopolitics changing anytime soon.

Hello,
as Ubuntu Touch (UT) is not dead. See https://ubports.com
They are doing an awesome job getting UT going.

I wanted to know if there is someone who wants to write a client for this OS :)

Cheers.

A lot of our team members ask for this feature, as using Android's system emoji keyboard leads to ??? on other platforms. Would be really helpful to have an Android emoji picker in the same style which is already implemented for reactions. The current system (typing : and emoji name) is not really working, especially for new team members.

Every time I start Mattermost, it asks me for url and account info, with no option to save it. Please use Android's Account backend to save login information.

In other chat apps, if someone writes a phone number, it turns into a clickable link automatically, so you can easily call someone. In our field, we are constantly giving phone numbers in our chats for field staff who need a call from a supervisor, and this would speed up our processes immensely. Thank you.

It would be nice if pressing and holding a picture for a few seconds in the chat window would let you share it to other apps. Right now in the React app pressing on a picture in a chat will make it light up a bit, but there's no prompt to do anything with the picture. Also it seems that there's no way to share pictures from within the app in general.

The only other OSS chat app I've found that allows this so far is rocket.chat (but only on their old Cordova app).

I'ld really like to see android auto support.

The android app is playing sound, when receiving notifications, even if my phone is on vibration. Probably due to the webview used.

I have a very long password and I would like to keep it. To make it easier to login on the phone it would be great if a QR is code shown on the computer which I can scan. (Where I am already logged into Mattermost.) Similar to Whatsapp where you login like this on the computer.

A font size option is quite an important feature to increase accessibility for all users including vision impairment users on various levels.
I think it is quite self-explanatory so there is no need for long descriptions

I have an Blackberry Passport with Blackberry 10 OS

I like very much Mattermost but android app isn't compatible with Android Runtime 4.3 which is the one on Blackberry 10

I can test and translate
