First, the “build.settings” file is ignored for Android Corona Enterprise builds. That file is used by Corona Simulator, not by Google’s Android SDK build tools. This means that all of your configuration in the “build.settings” such as permissions and plugins are ignored. You’ll have to edit your AndroidManifest.xml by hand according to Google’s documentation. You’ll also have to add plugin libraries to your project yourself according to Google’s documentation too.
You can download Corona Labs made plugin libraries from the below link. You’ll find them under the “Corona Enterprise” tab. Make sure to download the plugin version bundle matching your Enterprise version.

*.jar files are Java libraries. They go under your project’s “libs” directory as documented by Google here…

*.so files are native C/C++ libraries. They go under your project’s “libs/armeabi-v7a” directory since for Corona they’re compiled for ARMv7 processors only.

And if you ever include a 3rd party Android library that is open source in the future (note that these are not zipped up on our download page), then you would reference them via your “project.properties” file instead of copying them to your “libs” directory as documented by Google here…
