(I am new to Cocos2dx)
(Xcode with macOS, Android studio with Galaxy Note5)
macOS = Version 10.15.6
Xcode = Version 11.6
Android Studio = Version 4.0.1
Phone (Galaxy Note5) = samsung sm-n920k
I am making a stopwatch similar to https://cstimer.net.
The stopwatch is a cocos2d::Label* stopWatchLabel;
I am using the void update(float dt); function to update the stopwatch(Label) using the setString(); function.
It seems to work on Xcode. (Image below) (It is running)
But it doesn’t seem to work on Android Studio. As soon as I start the stopwatch, the program crashes. I think it’s because of the setString(); function. But I am not sure, and I can’t fix it.
How can I fix this code to make the stopwatch on Android?
