I am going through the No Texting While Driving tutorial. Doing everything just as it says. Obviously I've read that the current emulator won't allow texting if downloaded from the store. So I downloaded the 2.60u.
However, in the tutorial, it allows you to download the .apk and .aia. When I download the .apk to my phone, it works. When I download the .aia, upload to MIT App Inventor and CHANGE NOTHING, then compile into an .apk, suddenly it doesn't work. Even the phone won't recognize as an android app. It will install and open but the icons are different, suggesting my phone sees it differently. Also the size of the files are different:
Downloaded .apk: 2.1Mb
Downloaded.aia>Built .apk: 4.2Mb
So clearly there is a difference between these files. What am I doing wrong when I compile in the App? Will this never work?
