1. Create application
#!/bin/python3.4 #basicapp.py import kivy kivy.require('1.9.1') # replace with your current kivy version from kivy.app import App from kivy.uix.button import Button class MyApp(App): def build(self): return Button(text='Hello World') if __name__ == '__main__': MyApp().run()
2. Test basicapp.py runs
# Run the kivy app from terminal python basicapp.py
Save the file as main.py and execute buildozer. The first time is going to take a long time because a number of applications are going to be installed. It should be faster the next time buildozer is used.
3. Deploy main.py to phone
mv basicapp.py main.py #replace basic app as main.py buildozer init # modify buildozer file called "buildozer.spec" # make sure phone is connected # build and deploy buildozer android debug deploy
At this stage I had a lot of problems. Spoiler... I HAD TO TURN ON USB DEBUGGING MODE ON MY PHONE.
Here are some things I tried:
The problem: I could not get my application across to my phone (HTC One SV, Android 4.2.2). The first thing I noted was that my phone wasn't found when buildozer was trying to deploy.
I tried using HTC sync manager on a platform running windows OS. However, python-to-android is not supported by windows so I bailed on this idea and went back to my linux OS.
Next I checked the connection to my computer:
mtp (Media Transfer Protocol)
sudo apt-get install mtp-tools mtp-detect # device not found
adb (android development bridge):
sudo apt-get install android-tools-adb adb kill-server adb start-server adb devices # device not found # -waiting for device-
Then, I tried an emulator to avoid using a phone, but I had space issues so I scrapped this idea.
# Install emulator sudo apt-get install libgl1-mesa-dev sudo wget http://dl.google.com/android/ \ android-sdk_r23.0.2-linux.tgz sudo tar -zxvf android-sdk_r23.0.2-linux.tgz cd android-sdk-linux sudo tools/android
Finally I checked my phone. After turning on USB debugging mode, buildozer deploy worked as expected.
