I'm required to create a simple sms app for android which will be able to send and receive sms. In addition I'm required
to apply vigenere cipher such that no sms sending without encryption and no reading before encription.
I know about the encryption stuff. My problem is the sms app. im not good at xml but I know java.
Here is my idea of solution:
there should be a gui on which user can put sms and from which he/she can read incoming sms. the there should be communication between the GUI and the device so as services like sending sms and retrieving sms from inbox can be possible. then there should be
a mechanism for encrypting sms before sending and decrypting on receiving.
Need help on:
If one knows where I can find a free source code of app similar to above and which need minor changes especially on encryption
which is what we are studying, please direct me.
Or if its possible to write the above code in pure Java (without xml which I don't know), give me framework.
