Answer 1

It’s not mandatory to use @Override on public void onClick(View v), but could be a good reason to verify that you aren’t violating its signature. However, if you choose to use @Override, make sure your project is compliant with Java 1.6. If not, you might get the “… must override a superclass method” error. To enable this, right-click on your project folder inside Eclipse, and select Properties at the bottom. Then go to Java Compiler and select 1.6 from the dropdown menu at the top (Compiler compliance level).

Also make sure you are using Views OnClickListener:

button.setOnClickListener(new View.OnClickListener() {
    @Override   
    public void onClick(View v) {
         db.update();
    }
});
