Creating A Custom Sms/mms App In Android - Using Eclipse And Github - Why So Many Unresolveds?

Okay, here's where I'm at. I used Eclipse to import the code for the SMS/MMS app that is on Android devices. The code on GitHub is at https://github.com/android/platform_packages

Solution 1:

Mms as well as other system apps use private or hidden APIs that are not available through the SDK.

This has nothing to do with not being an open source platform, as you mentioned, but with the fact that you are trying to build the application in a way that is not supported and nobody says it was.

If you want to modify and build Mms, do it as part of the firmware build, using make, not importing the project to be built by the SDK in Eclipse.

Solution 2:

The stock MMS app built into a device's original firmware, signed with a private key, and is able to use some private API. Third party apps can't use the private API for various reasons, one being security. All the source is open if you wish to view it.

You can definitely build your own firmware, or ROM, as some call it, and run your own modified MMS app on it.

I don't know if you can make and install your own MMS app. You can find out by looking through the Play Store for similar apps or looking at the Android developer documentation to see what permissions and API are provided to third party apps.
