I am trying to put ads on my app and i downloaded an ad SDK . In the tutorial it says some things I don’t understand like :
-Adding SDK to your project
- Copy the InMobi-5.x.x JAR file and place it in the /libs folder in your project (you may have to create the directory if it doesn’t already exist). Make sure the IDE’s UI reflects this change. If you are using Android Studio, right click on your project and add to library.
- Add the below ProGuard configuration to the ProGuard configuration file (if it exists).
and
Making Changes to your Manifest File
Add the following lines to your AndroidManifest.xml file.
Add the following before </manifest> closing tag.
My questions are what is a libs folder.
What is a proguard configuration file .
lastly what is a manifest file .
By the way in using InMobi if aby of you have used it and can give me tips .
Thank you.
