Android – subprocess.calledprocesserror returns non-zero exit status 1

I received this error while running Kivy. I have installed ant

subprocess.CalledProcessError: Command '['ant', 'debug']' returned non-zero exit status 1

Who can tell me why this mistake happened? Because Python or ants or anything else?

resolvent:

I received this error, but the real error is slightly higher than this:

Buildfile: /Users/rallen/Documents/Devel/python/kivy/python-for-android/dist/default/build.xml

Google searched and I found it

It's said that you just create dist / default / project.properties and put them in

target=android-14

In that file, I actually used android-19, but it let me go beyond this problem
