I have an interest in either sending a text message with a modified UDH, or sending a text of binary data.
SmsManagerIt does not support any access to UDH, but sendDataMessageonly works on some GSM phones, and CDMA is not fully supported.
I did my share of research and came to the conclusion that I would need to find the way to the standard Android library, as bad as it sounds.
My first instinct tells me to do this using native Java and import it into my application. Does anyone know that this will cause Android security issues regarding SMS? In addition, I’m interested in how applications like TextPlus work without using the Android API, as they can send “texts” without using the phone’s standard text messages.
