Initialize boolean value "no such instance field"

Question

I get an error in debugging and I can't set this boolean value. I attached a screenshot of the error.

I call DeviceUpdateManager in my mainActivity like this:

public class MainActivity extends AppCompatActivity implements DeviceUpdateManager.OnDataCOM {
    DeviceUpdateManager deviceUpdateManager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.deviceUpdateManager = new    DeviceUpdateManager(this.serverCOM,this.getApplicationContext(),this);
    }
etc...
}

I cannot find the error... Is it related to the passing Context in another class?

EDIT:SOLVED I reboot the PC and restarted Android Studio and everything worked great.

Is it a new attribut in this class? Are you running the correct version of the application? Delete the current application and try again. — AxelH, May 03 '16 at 11:07
I think you are not initialized boolean value of "can" in InitializeVariables() method.Please check once — Kakumanu siva krishna, May 03 '16 at 11:10
@Kakumanusivakrishna What do you mean of initialized? I put in InitializeVariables() "this.can=true;" — Daniele, May 03 '16 at 11:12

It happens when you changed variable name in code and running application with older name in code.
