Error when using buildozer android debug

Description

I am trying to run the android debug however it keeps having an error at a specific point and I can find a solution on the internet that works. I have a very simple app that I would like to put on a cheap android table as a part of a fathers day gift and I never expected that the hardest part of making it would be downloading the thing. This is the first time I am using Kivy and Buildozer, so any help in avoiding or solving this error would be greatly appreciated!

Terminal

Command:

pi@raspberrypi:~/Desktop/Scoreboard_Controller $ buildozer android debug deploy run

I encountered this error and fixed it in the following way. Step1: Download android-ndk-r17c-linux-x86.zip manually from https://developer.android.com/ndk/downloads/older_releases

Step2: Extract files and move the files to /home/<user_name>/.buildozer/android/platform/ That's it.. Now re-run the code.

Note: This worked on ubuntu 18.xx and I am not sure about Raspian

this won't work on a raspberry pi.

It's maybe possible to run buildozer to build apks on a raspberry pi but:

• it's not going to be easy, and the normal documentation certainly won't work, you'll have to do a lot of things manually, and you'll get seldom help
• if you get it to work, building your distribution will take an aweful lot of time, it can easily take 20mn on a normal desktop, i imagine it's going to take hours on these low powered machines.

I have the same problem and did the things above. But i can't find a path "/home/aca/.buildozer/android/platform/". where should i move the files to?

Nibla, try to find .buildozer directory...

步骤 1：从**https://developer.android.com/ndk/downloads/older_releases手动下载 android-ndk-r17c-linux-x86.zip

**步骤2：**提取文件并将文件移动到/home/aca/.buildozer/android/platform/ 多数民众赞成它..现在重新运行代码。

我使用ubuntu18 尝试了上述方法 但错误还是一样，怎么办

Closing this issue as Google only provides support for x86_64 on Linux), making the RaspberryPi` unusable as a build tool.

Hopefully, in the future, aarch64 will take a lead also on Linux laptops, making life easier for RaspberryPi users.
