I'm trying to use ActionBarDrawerToggle in my project.So I imported project support v7 appcompact to eclipse.When I tried to add support v7 appcompact to my project as a lib,it didn't work.Shown as the picture,once I reopen properties->android it showed a cross. 

Android->libarary->add

errors shown

I tried to add support-v4 and support-v7 appcompact jars in support-v7 to my project->libs.Then I got no error.But when running application on my phone,it crashed.

Logging:java.lang.NoClassDefFoundError: Failed resolution of: Landroid/support/v7/appcompat/R$styleable;[crash log][3]

Tks guys.I solved the problem by myself.

I removed appcompact project,reimported it and ticked off "copy projects into workspace" while importing.The red cross in properties->android->lib disappeared.And my application run normally on my device now.

By the way,you don't have to import appcompact.jar or support-v4.jar to your project.And you have to remove existing support-v4.jar in your project because this would lead to "multiple dex files define".

Is there anyone who can tell me why I cannot use project from a different folder?Tks:)
