I have created an application where I have imported requests, json, urllib3. Now this app should send data to the live database. 
Now what should be the requirements for buildozer.spec file?

In buildozer. spec requirement requests, json, urllib3 and it is showing this error- 

Could not find a version that satisfies the requirement json (from versions: )
No matching distribution found for json
# Command failed: pip install --target=/home/kivy/Desktop/kivy-signup/.buildozer/applibs json
#
# Buildozer failed to execute the last command
# The error might be hidden in the log above this error
