Question

I’m currently developing a small test project with Android and I get the infamous @Override error:

The method onBackPress() of type KvizActivity must override or implement a
supertype method.

Here is the code that causes it:

public class KvizActivity extends Activity {
    /** onCreate(), onDestroy(), etc... */

    @Override
    public void onBackPress() {

    }
}

Now I know what you are thinking: there are tons of such questions and answers to them already. I know, I read all of them, still, I can’t get rid of it. I know the core cause of it is that Eclipse is using JDK 1.5 instead of 1.6 or higher.

But I have done all this: Went to Project -> Properties -> Java Compiler and I set it to 1.6. Error still there.

Then I went to Window -> Preferences -> Java Compiler and set it to 1.6 there, so it would be global, still it persists. Then I set the Project Specific Settings even though I already did this, I retried it. Nothing. I Cleaned the project and used Rebuild but still it is there.

I cant think of anything else to do.

Here is my Java version:

Java version "1.7.0_01"
Java(TM) SE Runtime Environment (build 1.7.0_01-b08)
Java HotSpot(TM) Client VM (build 21.1-b02, mixed mode, sharing)

I have Eclipse 3.7.1 which I believe is the latest.

I hope anybody can shed some light on this.

Answer 1

The method you want to override is onBackPressed(). For @Override to work, the method signature must match the method declared in the parent class. In this case, you misspelled the method name.
