Hi,
Is there a way to get email from people launching the app when they launch it After Google play store downloaded ?
You can use Statistics to do that without mail. They are already included in Google Play Console. You can open a send-mail-prompt but that would propably cause people to uninstall your app.
No , Impossible Only way you can is to give a input for email and then save it to any database and then send Mail or directly send Mail using SMTP without saving it in any database
You want automatically get email / google account used by the person who download your app?
Not possible
But you can set your app to ask for user’s email when he opens the app for the first time.
Maybe an other solution should be the app asking a code, i coule give, to open other screens.
