Android Studio - application Crashing on AddThis.jar - message "Sources not found"

I have a project using the AddThis SDK. I added AddThis.jar as a library for my project in Android Studio.

When I click the "Publish to Facebook" button, the application crashes with this log:

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.apploi/com.addthis.ui.activities.ATActivityGroup}: java.lang.RuntimeException: Unable to start activity ComponentInfo{com.apploi/com.addthis.ui.activities.ATShareActivity}: android.content.res.Resources$NotFoundException: Resource ID #0x0

Connection reset by peer

From what I can tell, this line suggests that the ATShareActivity problem has problems. java.lang.RuntimeException: Unable to start activity ComponentInfo{com.apploi/com.addthis.ui.activities.ATShareActivity}: android.content.res.Resources$NotFoundException: Resource ID #0x0

When I go into AddThis.jarand open the file ATShareActivity(or any other file inside the jar file), the message “Sources not found” appears at the top of the screen, with a link to the linkAttach Sources...

I open a link Attach Sources...and it allows me to select a directory, but I do not know what I should do here.

Any ideas on this would be greatly appreciated.
