mobile app development

Test Drive

Recall that (for now) your Android Python scripts run within the emulator, not within IDLE. So use the
tools/adb program to copy your program to the emulator. Call your program coachapp.py. When
the code is copied over, start SL4A on your emulator, and then tap your script’s name.

T ap your app’s
name, and
then tap the
“run wheel."

And there they are…Coach
Kelly’s athletes.

This is looking really good! Your app has communicated with your web server,
requested and received the list of athlete names, and displayed the list on your
emulator.

If you app doesn’t run, don’t panic. Check your code for typos.
Run your app again in the Python terminal by tapping on the little terminal icon to the
left of the “run wheel” within SL4A. If your code raises an error, you’ll see any messages
on the emulator’s screen, which should give you a good idea of what went wrong.
