Answer 1

It is an error for missing android-support-v7-appcompat.jar file in your libs folder. I suggest you to add it from your sdk folder's following location

sdk\extras\android\support\v7\appcompat\libs\android-support-v7-appcompat.jar

Answer 2

Please Refer this step:

1. From Eclipse (with ADT), select Window > Android SDK Manager.
2. From Android Studio, select Tools > Android > SDK Manager.
3. Start the Android SDK Manager.
4. In the SDK Manager window, scroll to the end of the Packages list, find the Extras
   folder and, if necessary, expand to show its contents.
5. Select the Android Support Library item.

Note: If you're developing with Android Studio, select and install the Android Support
Repository item instead.

1. Click the Install packages... button.

Check it this process...

Answer 3

actually solving this problem is easy: first you need to find android-support-v7-appcompat.jar and android-support-v4.jar in this folder :

sdk\\extras\\android\\support\\v7\\appcompat\\libs\\

(if you can't find them then you should install them from Android SDK Manager: Extras/Android Support Library)

and copy them into libs folder in your project inside work-space.

for example:

\\androidWorkspace\\projectName\\libs

and also make sure in eclipse

project/properties/Java Build Path

that first two files are connected with those copied files.
