The underlying code that powers Android text messaging is about to get an overall revamp and that could have good improvements and drastic changes for how users text each other on Android 4.4 KitKat and the future Android OS versions.
Looking in the non-developer angle , the changes will be practically unnoticeable. As the screenshot below indicates , soon users will be able to choose a default SMS app through the Android operating system itself or the Super Duper SMS. As of now , the SMS app developer must make it an option in the app’s settings in the device.
Google has mentioned in an Android Developers Blog post this Monday that many Android SMS apps improperly used “hidden” or “private” APIs which are a protected class of APIs for accessing core system functions such as Wi-Fi radio usage or even touch-screen input values. In the case of text messaging also known widely as SMS , these APIs control how the app interacts with the mobile radio and have been unavailable to Android developers until now.
Google has said that it plans to add SMS support to Hangouts for Android and the app already can be used for mobile phone and land-line dialing. In addition to the above , it is also going to have some integration with Google Voice. Google Hangouts has been marking and making its good way through the Google messaging world by initially debuting in Google+ for video and group instant messaging and then taking over Google Chat in Gmail and on Android.
