Android Question source code development


Licensed User
I|m a beginner in Android application and need to add some features to the source code to show some extra measurements
I am going to add some parameters on the application.
My application measuring air pressure, temp. and .... now, I would like to add some other parameters too.
Is that enough to add lines under>
for example:
Private LabelPanelAcceleration As Label
Private LabelPanelAirHumidity As Label
Private LabelPanelAirPressure As Label
Private LabelPanelAirTemp As Label
Private LabelPanelBatteryLevel As Label
these are included in the source code
and some other codes in any other module and part of code, is it work only to add my lines under the defined parameters in source code?

Best regards.
