How to use and package a JAR file with my Android app?

Question

I have an API in the form of a JAR that I would like to use in my Android app. Not sure if it should be part of the project in Eclipse or kept separate and added to the project properties. This JAR also needs to be packaged with the application, so how is that done for Android apps?

Answer 1

As explained by this SO question:

• Your Project -> right click -> Import -> Archive File -> yourjar.jar
• Your Project -> right click -> Properties -> Java Build Path -> Libraries -> Add Jar -> yourjar.jar

You must add it as "external JAR" files, and set the "Order and Export" in your Eclipse project.
