Source code of android messaging

Question

I am planning to create an application which the user can put security to their SMS. Is there a possibility for me to see the source code of the Messaging of Android phone? How?

Answer 1

I found this class on Grep Code. You can look around and see if it works for you. However, for anything related to SMS, you probably do not need to change the source code, just intercept calls at appropriate places !

Answer 2

Android source code is also mirrored on Github. The SMS/MMS package can be found on: https://github.com/android/platform_packages_apps_mms

Answer 3

See https://android.googlesource.com/platform/packages/apps/Mms for the Android Messaging app.
