If you don't need specifically use eclipse I encourage you to use Android Studio. I changed from eclipse to Android Studio and I think it's one of the best choices I did in my work.

P.S: That error looks like you don't have the appcompat library installed in your project. Are you using gradle? if so try to add it using the following line.

compile 'com.android.support:appcompat-v7:21.0.+'

If you don't use gradle you must add it manually.

EDIT: Here you can see how to import different libraries into your android project. http://android-er.blogspot.com.es/2013/12/create-library-project-with-appcompat.html

I think the problem is the library is compiled in 1.7 and eclipse is trying to to load it on 1.6. I updated my Java but its still not working I also get a warning when i create an Android project. "Unsupported major.minor version 51.0" – Suman Palikhe Mar 10 '15 at 11:10
Are you using Gradle? – acostela Mar 10 '15 at 11:12
Look into this post is a non-gradle solution. http://stackoverflow.com/questions/18025942/how-do-i-add-a-library-android-support-v7-appcompat-in-intellij-idea – acostela Mar 10 '15 at 11:32

This error means you're trying to load a Java "class" file that was compiled with a newer version of Java than you have installed.

For example, your .class file could have been compiled for JDK 7, and you're trying to run it with JDK 6. To solve this, you may take one of these solutions:

In Eclipse's menu

Window -> Preferences -> Java -> Compiler

Check "Configure Project Specific Settings".
Upgrade your Java runtime or Recompile the class if you have the source, using your local Java compiler (if you have one).

javac FileName.java

Try this :

Project->Properties->Java build path. On the "Order and Export" tab, make sure you have checked all the libraries the project is referring to in your case appcompat_v7

Be sure you have android:minSdkVersion="14", else change it to 14 and do Project -> Clean

Also you can take a look -> this or this
