The project cannot be built until build path errors are resolved

Project 'RedpinAndroid' is missing required Java project: 'RedpinCore'

these are classes this is properties>buildpath this is error page

Answer 1

This project depends another project named RedpinCore, so in order to build this, you need to reference the place where RedpinCore project resides, so that your project can find needed class definitions. Instead of this, you can remove this dependency, and add this jar to your classpath. The same classes can also be found in this.

Right click on your project Build Path/Configure Build Path...

Under Projects tab, right click on this project dependency and remove it.

Then copy the jar to your project and add it to your classpath.
