/**
 *
 * This is a simple sample/test application for AJVoIP demonstrating it's basic register/call capabilities.
 * You can extend it adding more features and/or use the library in your app in a similar way.
 *
 * IMPORTANT: Make sure to copy/include the AJVoIP.aar file to your project required libraries list !!!
 *
 *      just copy the AJVoIP.aar into your \app\libs\ folder and make sure that in your build.gradle you declare the libs dependencies like this: implementation fileTree(dir: 'libs', include: ['*.jar','*.aar'])
 *      ...or just add it explicitly. In Android Studio it can be done from File -> Project Structure -> Dependencies -> select your app module and add to declared dependencies with the + button
 *      more help here: https://stackoverflow.com/questions/16682847/how-to-manually-include-external-aar-package-using-gradle-for-android
 *
 *      Optionally copy also the ajvoip-sources.jar file for better inline documentation in your IDE. It might need to be selected from "Choose Sources" if not recognized automatically.
