Android-support-v4.jar dependency error

Question

I just created a new empty Android project with minsdk as 2.2 in the last Eclipse Luna. Eclipse automatically added android-support--v4.jar to the libs folder of the project. This causes an error in the console:

 Found 2 versions of android-support-v4.jar in the dependency list, but not all the versions are identical (check is based on SHA-1 only at this time). All versions of the libraries must be the same at this time. Versions found are: Path: /home/faizal/DEV/ADT workspace/myNewProject/libs/android-support-v4.jar Length: 758727 SHA-1: efec67655f6db90757faa37201efcee2a9ec3507 Path: /home/faizal/DEV/ADT workspace/appcompat_v7/libs/android-support-v4.jar Length: 648327 SHA-1: ded9acc6a9792b8f1afc470f0c9cd36d178914cd Jar mismatch! Fix your dependencies 

This is because I also have an appcompat_v7 support library project that I use for another project and was created by old Eclipse (I think it was Juno .. it was part of the ADT package).

I know that the solution is to remove one of the cans, but which one and why?

Answer 1

You just need to:

• Right click on myNewProject project
• Go to Android Tools> Add Support Library
• Approve permissions and update library
• Repeat this process for the appcompat_v7 project

Android Support Library will sync (:

Answer 2

You import the appcompat_v7 library, which also has android-v4.jar support, but a different size. Just copy android-v4.jar support from your project library to the appcompat_v7 folder. Folder paths are in your post, for information only.

Answer 3

• Right-click the demoProject project
• Go to Android Tools> Add Support Library
• Approve permissions and update library
• Repeat this process for the appcompat_v7 project (or any library

Answer 4

• Look at the path of discrepancies
• Delete file in project folder> libs
• Copy the file from the appcompat libs folder to the folder with the project folders
• Close and reopen Eclipse
• Clear project
