How to solve Must Override a Superclass Method Error

Ever import some Android sample code into eclipse and get the dreaded  "Must Override a Superclass Method Error"?
In this blog post I am going to explain the source of the problem and how to fix it.

You might receive an error like this:
The method onClick(View) of type new View.OnClickListener(){} must override a superclass method Java Problem





The Source of the Problem: The project was written with a Java JDK Compiler compliance level of 1.6 but your eclipse setting is 1.5.

How to fix the problem: 


Right click on your project and select "properties"
Select "Java Compiler" 
Make sure "Enable project specific settings" is checked
Change the "Compiler compliance level:" to 1.6
Save the changes. 
Now select "Project" > "Clean..." 
Your project should now build without any errors.

Please feel free to post comments or questions. I usually post a reply within a day or two.

I created it. I also am sharing it. Here is my blog post about my dark color theme and a link to download the import file.

If you set the Compiler to 1.6.and still you get this error. Try to check your imports. Eclipse always try to do this 'import android.content.DialogInterface.OnClickListener' instead of the doing this -> 'import android.view.View.OnClickListener'. That solves my problem.

Sorry to be negative but this didn't work for me. Still getting told to remove @Override. Any other suggestions ?

Just found the solution on another site. After setting Compliance Level to 1.6 and BEFORE running Clean, it is essential to uncheck Project > Build Automatically.
