The Import android.support.v7 cannot be resolved

问题：

I am new to Android. Currently, I have the 

adt-bundle-windows-x86-20131030.zip

 (Windows
32 bit) installed - and have successfully installed the Android SDK and Eclipse. Also, I have updated everything in the Android SDK manager. Now, I am working in Android v-4.4.2

My project runs successfully, but when I import 

android.support.v7.app.ActionBarActivity;

 and 

import
android.support.v7.app.ActionBar;

 the project won't debug. I get the error 

The
Import android.support.v7 cannot be resolved

I searched in Google and installed 

Android
Support Library

 then added 

v7

 in
my project.
File->Import (android-sdk\extras\android\support\v7). Choose "appcompat"
Project-> properties->Android. In the section library "Add" and choose "appCompat"

Screenshot



Successfully added in 

appCompat

 but
still I am still getting the error.

解决方法：

Go to your project in the navigator, right click on properties. Go to the Java Build Path tab on the left. Go to the libraries tab on top. Click add external jars. Go to your ADT Bundle folder, go to sdk/extras/android/support/v7/appcompat/libs. Select the file android-support-v7-appcompat.jar Go to order and export and check the box next to your new jar. Click ok.
