I looked at code here: How to send image via MMS in Android?
And here: Unable to send MMS using SmsManager
And I did some research from other places as well, but so far I'm quite confused about how to send MMS messages to people without using intents.
If I go to the Android documentation here, in Telephony there is the SMSManager class. In API Level 21, they added a function called "sendMultimediaMessage()" that sends an MMS message.
void sendMultimediaMessage (Context context,
Uri contentUri,
String locationUrl,
Bundle configOverrides,
PendingIntent sentIntent)
Parameters
context Context: application context
contentUri Uri: the content Uri from which the message pdu will be read
locationUrl String: the optional location url where message should be sent to
configOverrides Bundle: the carrier-specific messaging configuration values to override for sending the message.
sentIntent PendingIntent: if not NULL this PendingIntent is broadcast when the message is successfully sent, or failed"
I can't seem to find any real usage or examples of this code being used. In my application, I want to send a picture message to someone in the background--no application should open in this process (which is why I can't use an intent).
For sending an MMS, I have a few basic questions:
1) How can I take a simple phone number and convert it into an appropriate "address" that MMS can use?
2) How can I actually use this function if all I have is a file path to my image and a phone number to send it to?
I am very new to this, so if someone can provide a thorough explanation I would be very grateful.
