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.

Answer 1

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

Answer 2

Remove below snippet from Project/build.gradle file.
