[ArchLinux] Kivy .py to .apk - Buildozer failed to execute the last command

[Meta.Morph]

Servus,
wollte mich mit Python/Kivy beschäftigen. Leider funktioniert das ganze nicht ganz so toll. Zwar kann ich die Bibliothek einbinden und Programme ausführen aber die Umwandlung in APK-Dateien schlägt fehl.

Hab mich gestern und heute schon zu lange damit beschäftigt – vielleicht weiß einer von euch Rat.

Ein Problem ist: von „offizieller“ Seite, finde ich nur Anleitungen für Ubuntu. Kivy und Buildozer können zwar über pip installiert werden. Jedoch werden noch Abhängigkeiten aufgezählt, die unter diesem Namen nicht in den Arch-Repos zu finden sind. Ich denke, das ich alle Abhängigkeiten erwischt hab…

Spoiler: Fehlercode

… hab schon einiges gekürzt. Hoffe es war nicht zu viel.

Offensichtlich hat er Probleme mit Java. Natürlich hab ich OpenJDK installiert. Eben so dieses Gradle, welches hier einen Fail wirft.

Hatte gestern offenbar viel Zeit zu verschenken… 😥 und bin in dieser buildozer.spec Datei diverse Einstellungen durchgegangen und hab verschiedene API und SDK Versionen ausprobiert oder hab die Requirements spezifiziert.

Am Ende wollte ich „nur noch“ eine einfache Hallo-Welt-App umwandeln.

Am Ende gibt es noch sicher die Möglichkeit, das ganze in einer Ubuntu-VM zu realisieren, aber eigentlich bin ich davon nicht richtig begeistert…

Da sowohl Kivy als auch Buildozer im AUR zu finden und aktuell sind, muss das ganze doch auch unter Arch funktionieren!?

 

[madmax2010]

zeig doch mal eine entsprechende anleitung

 

[Meta.Morph]

zeig doch mal eine entsprechende anleitung

Diese Pakete habe ich installiert:

yay -S python-buildozer python-kivy android-sdk android-sdk-build-tools ncurses5-compat-libs

sudo pacman -S gradle libtool libffi jdk-openjdk git zip unzip autoconf pkgconf zlib ncurses gradle cmake openssl cython

Dabei bin ich u.a. nach diesen Anleitungen vorgegangen:
https://kivy.org/doc/stable/installation/installation-linux.html
https://kivy.org/doc/stable/guide/packaging-android.html
https://buildozer.readthedocs.io/en/latest/installation.html#android-on-ubuntu-20-04-and-22-04-64bit

Wie gesagt, mein Code läuft als Py-script ohne Probleme durch.
Lediglich die Umwandlung scheitert.

Gleich am Anfang passt ja schon was nicht:

/bin/sh: Zeile 1: dpkg: Kommando nicht gefunden.

Zu Not würde ich das ganze einfach in einem Ubuntu Container bauen lassen. Ist manchmal einfacher, als Stunden lang zu versuchen das auf ein System zu migrieren, was nicht offiziell unterstützt ist.

Gleich am Anfang passt ja schon was nicht:

Das mir das nicht aufgefallen ist... ist eine typischer Fehler...

ABER: er wirft immer noch den selben Fehler.

Zu Not würde ich das ganze einfach in einem Ubuntu Container bauen lassen

Werd mich jetzt auch dran setzten und einen bauen. Dennoch nagt das ganze doch wirklich, das ich das nicht auf unter Arch ans laufen bekomme.

Warum soll Kivy/Android nur unter Debian und co. anständig laufen?
Ist das tatsächlich so ein Nischenthema?
