Deploying Your Kivy/Python App to Android with Buildozer

[@erik-sandberg]

What a sick intro. I wrote all of the steps down in the description of today's video, so you can copy/paste commands into the command line if you want! Good luck getting your apps on Android everyone!

Thanks men

yeah the intro was insane thanks

[@anishfernandes1281]

I got the apk file generated but when I installed it in my phone the app crash closes..it shows loading and then closes.. I'm using kivy, kivymd and pyttsx3 packages.. Do you know why this would happen ?

[@tranguyen758]

@@anishfernandes1281 Have you fixed that problem? I'm having the same issue 😂. I use kivymd, plyer in my app

[@johnabual-nile9333]

I never comment on anything but this helped me a ton (especially after trying to figure it out for over a week about 10 hours a day). If you are using a python module that requires you to utilize the internet (like say, paho-mqtt), make sure you change the permissions in your buildozer spec file (i think it's line 91) and allow the permissions for INTERNET. (i.e. delete the #). Before then my app would display the splash page and then crash. Literally, no video or article or stack overflow says to do this, hopefully this helps someone to not spend over 80 hours figuring it out ;)

Excelent video. For Xiamoi users, you need to toggle "install via USB" too, under "USB debugging" for the deploy to work

[@programmingislife1517]

i still have an error

[@timmaassen9234]

I love you. It took me THREE days to get my app run on my phone having several errors I could not find anywhere. The worst thing is that I only discovered your video last night. This helped me so much. Still had to fix few errors which you did not have in the video (still ateup a lot of time) but now I have my app!!!!! Thank you so much!

[@neopiru7904]

very well done. I ended up compiling apk for x64 devices and its only 12mb in size. For anyone having issues with gradle error be sure to use the same jdk-8 as mentioned in the video. Don't use the latest one!

Fantastic work here, just wanted to add that the developer must make sure that cython is installed in the system and not only virtual env as it will throw up some error messages,

[@minihohtis5906]

I am having error "Could not find a version that satisfies the requirement Cython". When I try to install cython to ubuntu via terminal I always get etiher requirement satisfied or cython is already at newest version. Just to be clear if I understand you correctly: by system you mean Ubuntu or Windows?

Thanks for it, I started to write my college graduate work in python with kivy frontend, and met some problems with deploying it on Android. Thanks for that video, your tutorials are amazing. Anyway, currently I have got an error while building .apk: No Module Cython (i typed install command for it, so here is some magic).

[@Supbuter]

UPD problem was fixed after installing Cython package by pip. It woud be nice if you'll update description.

[@erik-sandberg]

@@Supbuter Awesome! What was the exact command you had to run? I didn't run into the same error. What did you do differently from the tutorial?

[@Supbuter]

@@erik-sandberg 'pip3 install Cython' fixed it. Anyway, later I tried to build application with matplotlib, did all things devs require, and got stock by those linker errors: clang++: error: linker command failed with exit code 1. error: cannot find -lpython3.8m Maybe you could help me, or say where can I find solution? This app is my college graduate project, and there will be deadline soon, but I can't built even simple matplotlib app. Thanks in advance!

[@erik-sandberg]

@@Supbuter Matplotlib is kind of a tricky one. I don't think I'll get into using that soon -- for now I would suggest using the kivy.garden.graph module if you're just using linecharts. That's what I've been using in my apps. Good luck!

Hi friend, My question is, I used matplotlib kivy garden to display my graphs and it's working, is there any chance of Working well when run in python and not work when I convert it into APK Actually what I mean is Everytime we have to convert it into APK and see its working or not, or It can definitely work when it is successfully run in python?

what is mean (lld not found, linking without it. consider installing lld if linker)?

It means, that there is no package lld in your computer. Install it with sudo apt-get install lld. P.S. I have got an error while buildozer downloads cython. It occures due to some ssl package from python2 repository. So, if you have that error, you should install package libssl-dev with sudo apt-get install libssl-dev

[@ruardstolper9072]

Hey Erik, mu first reaction ever. Thanks for your tutorial! With your help I made my first APK. But when I wanted to upload it I saw that google only accept AAD format (since august). Is there a way to make an app in AAD format? Could you make the same kind of video about that? Greetings, ruard

[@justaivideos]

Incase you find out please tell me :)

[@ianrajkumar]

Erik, if we use only "buildozer -v android debug", will it generate the apk file without installing it on the phone? Meaning, we can get the apk without connecting our phone and then install it later?

[@erik-sandberg]

I think there's probably more to that error, but I believe it's related to not having libssl installed. Try doing `sudo apt install libssl-dev`, then you might also need to clear everything from your earlier attempts with `rm -rf .buildozer` from the directory that has your buildozer.spec file. Then try compiling the app again!

If you have issues with cython not being installed... but it is follow these steps "Write in the terminal cd /bin/ && sudo gedit cython in the editor that will pop-up write cython3 $@ this will pass all the arguments from cython to cython3. Save the file and write in the terminal sudo chmod 755 cython to make it executable.
