Import 3 SDKs, get error: Found 3 versions of android-support-v4.jar

Question

I create an Android-application. Have imported all my SDKs (GoogleSDK, FacebookSDK, AppCompatSDK)

Right-click on my project -> properties -> Android -> Add my 3 SDKs. Press on Apply and get this error:

Found 3 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.

What should I do? The project isnt red, there is nothing red in Order and Export, & Libraries

( This app will work from API 8 & above )

P.S If you know any link to a good tutorial there it shows how to make loginbutton for FacebookSDK 3.5, login and go back to a new Activity would be nice. Just login & signout, nothing more.

Thank you.

Answer 1

For different versions of android-support-v4.jar file, do following steps:-

1. Go to libs folder of any of the most recent project (which contains latest jar file)
2. Right click on android-support-v4.jar file and copy it.
3. Paste the copied file in other project which are showing error.
4. Clean the project and run it.

For integration of any of the SDKs, if you are adding a jar file, just copy the jar in your libs folder and Right click the project > Select Properties > Libraries tab > Add jars > Navigate to your project's libs folder, select the SDK's jar you want to add and you are done.

Clean the build and run.

Here is how I your setup should be:

Workspace
  |
  |-Library Project 1 (FacebookSDK)
  |---|...
  |---|libs
  |-----|-android-support.jar
  |-Library Project 2 (GoogleSDK)
  |---|...
  |---|libs
  |-----|-android-support.jar
  |-MainApplication Project
  |---|...
  |---|libs
  |-----|-android-support.jar

Make sure that for each project, the android-support.jar is included in Android Private Libraries folder:

• right click on {{project name}}, select Properties from the menu;
• a Properties for {{project name}} window appears;
• select Java Build Path from the left;
• select Libraries tab;
• make sure you have the jar in Android Private Libraries, if not add it;
• select Order and Export tab;
• make sure the checkbox for Android Private Libraries is selected.

The last think you should check is that you have the same version of the jar in all your projects. do the following for all your projects:

• right click on {{project name}}, select Android Tools/Add support library...;

The same thing applies to all jars, not only the support one. You have to add it to the build path and make sure you have the same version of it in all your projects.

Let me know if you got it working.
