I am trying to create an app that sends an MMS message.
Since it appears you can not programmically send an MMS message, it needs to use the devices "default" application to do the actual sending.
So, I am using the code found at this link to invoke an Intent for the default MMS app:
https://www.b4x.com/android/forum/threads/send-an-mms-using-b4a-question.16360/
But, one of my testers said that they set "Google Hangouts" to be their default SMS/MMS app. So, when my app went to do the intent launch, it popped up the [typical] "Complete action using..." prompt and google hangouts was not listed as an option, and if they instead selected the built-in SMS app, when the SMS app opened, it said "Google Hangouts is your default SMS app, so Sending Disabled in this app" or something similar to that.
So, how can I send an MMS that will use the user's selected MMS app?
