创建一个jar文件-Dalvik错误

Question

I have an android project that contains only a .java file. This java file extends the class Services.

I am trying to build a jar file using * * Build Fat JAR **.

I did the following:

• right click the project -> select Fat Jar and inside the Configure Fat Jar Plug-In I've selected the OPTION: select Manifest file. With next-> finish I've managed to create the .far file.

PROBLEMS:

The jar icon has a red x mark in front of it. When adding the jar inside another project and when running the application (creating apk) I get the following:

Dx trouble writing output: invalid header field. Conversion to Dalvik format failed with error 3

What am I doing wrong? Need some help.

Thank yiu
