Question: Hi I am working on `PhoneGap` through a command line interface. 

I am able to create a project, and run an android emulator from the command prompt in Windows 7.

Since I imported and copied the project into my workspace in eclipse, it is showing some errors in the main class which extends `CordovaActivity`. 

The error is:

```
"CordovaActivity cannot be resolved to a type".

```

What should I do?

Answer: 
For those who don't want to use it from command line just add an external library cordova-android project to resolve this issue.

Follow these steps:

1- Download Cordova android zip from here <https://github.com/apache/cordova-android>.

2- Extract zip anywhere on your PC. Go inside framework folder.

3- Import this extracted zip folder/framework in your eclipse as an existing project which will result in Cordova project(library) in your workspace.

4- Now right click on your app project -> Properties -> Android. In the Library section choose 'Add' and select Cordova project(library).

5- Finally add import org.apache.cordova; to use extend CordovaActivity.
Add `cordova` jar in your project and then in your `Activity` which extends `CordovaActivity`
add this line to import the `cordova` classes

```
import org.apache.cordova.*;

```
