Question

I am trying to create and use jar file in an Android project under Eclipse. I have tried various methods without any success. Here are the steps:

• Create jar file from the source files jar -cf lib.jar *.java
• Copy jar file to libs folder
• Right click, Build Path->Add to Build path
• Now, compiler gives unresolved symbols if I try to use a class from the jar file?

Can someone please let me know correct method to create and use an external jar file for the Android project under eclipse.

2)Right click on project name.

3)Select properties.

4)Select Java build path.

5) Select Libraries.

6) Click Add Jars.
