Was returned It is a table based on the result Since it was API21, the u example is a guess ~~ Troublesome to move the simulator ~~
For Y and X
Unknown pattern character 'X'
Unknown pattern character 'Y'
I couldn't get it If anyone knows anything, please let me know
Also, since this is the first output in such a place, I would appreciate it if you could comment if there are any points that cannot be reached. Please make it full bocco

When I checked the reference now, It seems that it was an API level problem that the X and Y values could not be obtained.
That's why you should run the emulator at all
