Just to clear up my question a little more, what I need to do, is implement Tapit SDK to an android APK made by GameSalad.
I know mostly the entire process already, and my only problem is getting the ad to show.
To give you a quick run through of my method, I decompile the apk to smali with apktool, I also have a tapit apk that I decompile so I can just have the smali code for that, and then I put it inside the activity I need it in. I make sure I import tapit, add the lib folder under com, edit the android manifest xml, and then recompile, and resign.
The app doesn't crash anymore, but it doesn't show my ad either.
I know it is possible to edit an apk in this manner, and I also know about dex2jar and editing it in jasmine, but I can't get it to work that way either.
If anyone would have any insight on this, I would greatly appreciate it.
Thank you.
just add the jar file from the ad provider SDK to the decompiled apk and you are done:)
