Launch chat with user in MS Teams Android app from my android app

Question

I have an Android app, where a tap on a button should launch Microsoft Teams Android app and open a chat with a pre-defined user.

Is it possible to do and if yes - how?

Answer 1

If you know user's E-Mail with which he/she is registered in MS Teams (ex: username@email.com ), you can directly open chat with him/her using one of two options:

1. show user a chooser sheet with a choice to open chat in MS Teams Android app or one of web browsers:

    val sendIntent = Intent(Intent.ACTION_VIEW, Uri.parse("https://teams.microsoft.com/l/chat/0/0?users=username@email.com")) if (sendIntent.resolveActivity(packageManager) != null) { startActivity(sendIntent) }

2. force open chat with user in MS Teams Android app. Same as above, but substitute in Uri https with msteams :

Uri.parse("msteams://teams.microsoft.com/l/chat/0/0?users=username@email.com")
