Convert Python to Android with WINDOWS & LINUX + Fix Common Bugs

[@timmaassen9234]

I always get the error message: "Unknown command/target android" after the command "buildozer -v android debug". I followed your tutorial step by step so far. I only used a different python-file and some picture which were all in the folder- Do you have an idea what the problem could be? Good explanations btw. ;)

[@PythonSimplified]

Hi Tim! 😃 Are you using Windows 7 by any chance? Sorry, I haven't encountered this error earlier but I've noticed somebody on stack overflow did and they were using Windows 7: stackoverflow.com/questions/60077141/building-an-android-app-with-kivybuildozer/70162831#70162831 It seems that something is wrong with the Buildozer installation but I couldn't find a proper solution to it online... everyone just replies with "you can't work with Buildozer on Windows" and refers to Google Colab (which never even seemed to work for me). I don't think it's the problem here, but does your version of Kivy and KivyMD matches mine? you can find out the exact version with "conda list" or "pip list" and make sure you update it in the requirements in your buildozer.spec file. (it's a long shot, it's probably unrelated but it's worth a try) If everything matches but the error repeats, do you mind loading your code to Github so I can take a closer look? Thanks! 😊

[@timmaassen9234]

@@PythonSimplified Thanks a lot! I found a way now. I still don't now what the problem is but here is the short story: I used to convert my python apps via Colab to APKs for my android phone. For some reason it stopped working and that is why I looked up your video. Your way doesn't work for my setup for some reason (maybe I did something wrong idk). But you gave me that idea to check the version of my kivy application. Now that I have updated my kivy, the old way works again! So thanks again for the quick reply and for your video! A lot! Because I spend 3 days on that problem by now and it didn't cross my mind to check if my kivy version was old (yeah I guess I am dumb lol). Thanks!

[@PythonSimplified]

@@timmaassen9234 wow!! I can't believe it worked!! I didn't think it was the problem but I'm super happy it helped!!! 😃😃😃 Also happy to hear that the Colab way works for you! Do you mind sharing which tutorial you followed to get it done? It might help other folks who stumble upon this video and have issues with the WSL way 😊

[@PythonSimplified]

And you're most certainly not dumb!!! It wasn't an obvious issue!!! It's just a matter of troubleshooting! 😉

[@keithramey4723]

@@PythonSimplified So I managed to get this to work. It took over an hour to run. Didn't think my computer was quite that slow. I looked back at my buildozer.spec and these lines are still commented out. Was this the reason it was so slow? Should it have worked with those lines commented out? I haven't done a deep dive into understanding buildozer yet. Thanks for the video!

[@PythonSimplified]

@@keithramey4723 it's substantially slower than compiling a desktop application! I believe it's because Python is not the go-to language for Android apps. It's definitley usable! But professional developers usually use Kotlin or Java for that... 😊 I think that in the future Python will be much more popular for mobile apps (and in general 😉), but until then - it's a long conversion process! Also you'll need to uncomment those lines because they don't count as commands if you leave them as a comment... but if your icons are already showing on your mobile device - you don't even need to! 😀

first of all, it worked perfectly fine though it took like an hour so thank you so much for the tutorial. my question is, so the second time we want to update the changes, do we run like this for like an hour? love from Ethiopia

[@PythonSimplified]

Hi Samri 😊 If you're just updating your app, without deleting the "bin" directory - it shouldn't take you so much time as you already have most of the packages built. So if buildozer detects the package in the directory - it should skip installing it and move on to the next command. On my end, it was substantially faster to update an existing .apk file rather than to build from scratch. I usually change the title and name of this file into "myName_version2" or something of that sort so you can keep your previous version of the .apk as well to help with testing 😀 Good luck! and please let me know how long the update took on your end... I believe that on my end it takes 20 minutes to build and about 10 minutes to update. Annnnnd of course sending some love back from Canada! 😁
