I was wanting to know if Android had a similar feature to the iPhone in that you can use an HTML A tag to send an SMS by setting the HREF
attribute to the phone
I found the following which may help you:
http://tools.ietf.org/html/rfc5724
You can check sub-section 2.5 or 2.6 of this RFC to give you some additional pointers on formulating a proper SMS URL.
For example:
...
<a href="sms:+19725551212?body=hello%20there">SMS Me</a>
...
Notice the 'escaped' character for the 'space' in the example above.
Hopefully the Android browser will permit you to generate XHTML forms based on this syntax. I believe they will (if I have some time over the next day, I shall give it a try on my Galaxy S).
If multiple recipients needed, this works:
Android:
sms:+15558675309,+15558675301?body=Text%20Here%20end!
iOS, macOS:
sms://open?addresses=+15558675309,+15558675301/&body=Text%20Here%20end!
I have noticed if you use a qrc code with text for mms:<phone_number>?body=<your message here.>
this seem to work and avoid the error: invalid recipient(s)
here is a test qrc http://qrcode.kaywa.com/img.php?s=8&d=mms%3A555-555-5555%3Fbody%3DYour%20Message
You could use a CSS trick to display one or the other: CSS media query to target only iOS devices
@supports (-webkit-touch-callout:none) {
/* CSS specific to iOS devices */
.android { display:none }
}
@supports not (-webkit-touch-callout:none) {
/* CSS for other than iOS devices */
.ios { display:none }
}
<a class="ios" href="sms://+12345">SMS me</a>
<a class="android" href="sms:+12345">SMS me</a>
That should work:
<a href="sms:+437722735932">contact</a>
If you need a URL working for both Android and iOS you can do this trick:
sms:+123456789?&body=hello%20there
