🚨 Important Tip for Viewers 🚨:
For a smoother experience using the Android Calculator app, consider this tweak. In the 'Main.java' file, within the 'MainActivity' class, locate the line 'double firstNum;' and modify it to 'double firstNum = 0;'. This adjustment helps prevent potential errors when clicking 'equal' before any operation. Your feedback is valuable!

Thank you for your tutorial. The only question which is beside from your tutorial concept. If you could answer i would appreciate. When I press dot on my keyboard the dot (point) appears on number field but calculation crashes and the app exits. What could be the correct way of this ?
