Answer 1

Maybe the ADK update has messed-up with your project's build-path. Try removing the JAR and add it again to your libs folder, and do a Clean Project.

following poster's comment about not having a libs folder:

You should try this:

Remove all references to the JAR in your project -> your code should not build without error anymore

Create à libs folder at the root of your project

Copy the JAR into the libs folder

(If still not running OK) Right click your project > Android Tools > Fix Project Propertie

If you want to use a Jar in android application you may create it like this:

1. Open your IDE
2. Click on new
3. Choose new Android project
4. Give the name of your project
5. Check option make this project as library
