Kivy to Android apk using Buildozer on Ubuntu not work

Question

I try to build my APK file for Android using Buildozer 1.2.1.dev0 on Ubuntu 19.04, but I get this error: Build failed: Requested API target 27 is not available, install it with the SDK android tool.

I use this command lign: moha@moha-ubuntu:~/PracticePython$ buildozer android debug deploy run

this is my error in terminal:

    [INFO]:    Will compile for the following archs: armeabi-v7a
[INFO]:    Found Android API target in $ANDROIDAPI: 27
[INFO]:    Available Android APIs are ()

Answer 1

I know this is an old thread but I had the same issue. I fixed it by

rm -rf ~/.buildozer

if it exists and also

rm -rf <your project folder>/.buildozer

Then run buildozer again:

buildozer -v android debug

You will be prompted to agree to licences a few times. You need to type 'y' not just hit space or enter.

After doing this all should work as expected. It did for me anyway.

Answer 2

Hello and welcome to StackOverflow.

The error message indicates that you've not get any Android SDKs installed, and that you'll need to install the SDK for Android 27 to be able to build your app.

There should be plenty of guides for how to do this on Google; here's one example (different Ubuntu version but likely similar steps): https://linoxide.com/ubuntu-how-to/install-android-sdk-manager-linux-ubuntu-16-04/

Answer 3

I managed to make progress with this by un-commenting and changing the API version in buildozer.spec

# (int) Target Android API, should be as high as possible.
android.api = 32

Now buildozer -v android debug does ask for my confirmation.

Now I am getting Exception in thread "main" java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema , but this is a new story
