Check that the Java version meets the specification in the Buildozer install instructions.

In future please use the user groups for usage questions.

Check that the Java version meets the specification in the Buildozer install instructions.

In future please use the user groups for usage questions.

I have checked my java and changed it to 1.8.0, it worked but i am also having problems with my gradlew.

It seems like my gradlew requires open jdk11 to clean assemble debug....... If i try to switch to java 11, Buildozer will give the error at the top of this page................... I don't know what to do, pls help??

The error now is ~

I have checked my java and changed it to 1.8.0,

See the Buildozer install instructions for the correct Java version.

I expect getting the Java version right will address the Gradle issue.

When you get it right to be on the safe side, do this too https://github.com/Android-for-Python/Android-for-Python-Users#changing-buildozerspec

And FYI if instructions for finding Gradle's actual first message https://github.com/Android-for-Python/Android-for-Python-Users#gradlew-failed

Ridola20 · 2023-10-02T07:00:56Z

Android on Ubuntu 20.04 and 22.04 (64bit)

(expected to work as well in later version, but only regularly tested in the latest LTS)

sudo apt update
sudo apt install -y git zip unzip openjdk-17-jdk python3-pip autoconf libtool pkg-config zlib1g-dev libncurses5-dev libncursesw5-dev libtinfo5 cmake libffi-dev libssl-dev
pip3 install --user --upgrade Cython==0.29.33 virtualenv # the --user should be removed if you do this in a venv

add the following line at the end of your ~/.bashrc file

export PATH=$PATH:~/.local/bin/

If openjdk-17 is not compatible with other installed programs, for Buildozer the minimum compatible openjdk version is 11.

Ridola20 · 2023-10-02T07:01:45Z

On the site, it says either 17 or 11, but i tried both and still does not work for me

At least, between..??

Check configuration tokens

Buildozer is running as root!
This is not recommended, and may lead to problems later.

i get this with version 17 and 11.....But it seeems to work perfectly with 8 except that gradlew get the error : -> #1712 (comment)

RobertFlatt · 2023-10-02T17:10:03Z

Follow the install instructions, always.

Some possibilities to explore (and 2-4 will definitely cause other issues later):

Something is corrupted from the previous attempt, delete ~/.buildozer
Buildozer is running as root, this is known to cause issues on Linuxes with user accounts, you ignored the warning.
The app in on the Windows partition, the install instructions explicitly say don't do this.
The app is in a venv on the Windows partition, is this a Linux Python or Windows Python venv ?

Ridola20 · 2023-10-03T12:34:55Z

Thank You Very Much

I have changed to 17 and went further to meet another error

Warning: An error occurred while preparing SDK package Android SDK Build-Tools 34: Remote host terminated the handshake.

RobertFlatt · 2023-10-03T17:07:52Z

Looks like a network error.
I have not seen this before.

misl6 · 2023-10-04T16:40:32Z

Yeah, that definitely looks like a network error. Can you try to clean your .buildozer folder and try again?

Ridola20 · 2023-10-05T09:52:50Z

Thank you very much
I buildozer appclean
and started the whole buildozer android debug process from start

Getting other bugs/errors but they are things i can handle for now, i'll update you on other error that shows up later
