Compiled app crashing on startup

[JonZavialov]

Hi Johannes, thanks for building these wheels. I have two questions:

1. I compiled the app and installed it on my phone. When I try to open it, it is instantly crashing. Is there a way for me to see the logs, or read debug information to see why this is happening?
2. How do I specify python dependencies for my project? I am not compiling the app and developing it on the same computer, so it doesn't have the dependencies installed. This is probably what's causing it to crash.

Hi,

• You can log the errors using "adb logcat --regex '<your app package name. Probably 'main.org' by default>"
• The Android studio using the "Profile or debug an APK" tool. Just search Online, it's really easy to set up. (2 minutes max.)

It was actually descrtibed in the guide. You need to modify your PySide6 installation. I hope you have it installed through virtualenv. If yes, then you just need to go inside your virtual environment folder and then into /lib/python3.11/site-packages/PySide6/scripts/. Now modify the android_deploy.py script by using any editor of your choice. Search for the line run buildozer. Above this line write an input statement. Just something like input("Don't know lol") and then execute the build process as usual. When the script starts you'll see your input statement comming up. At this moment there should be a new file in your current directory named buildozer.spec. Edit this file. You'll see a line saying requirements = ... The last option there should be PySide6. You can just add another comma and add your dependencies (all by comma separated). You can also specify version numbers or compile them from git like you would normally do. If you need additional help I can also record a video for you to easily show you everything.

Thanks for your help, I really appreciate it! I used your wheels with the tutorial from here. I'll try your tutorial tomorrow and update this thread.

Here is my process (I am using Ubuntu 22.04):

• Create a virtual environment- I downloaded Python 3.11 from deadsnakes/ppa, but couldn't create a venv the normal way. I realized you also need to run sudo apt install python3.11-venv. Then it works.
• Install python dependencies, make sure it runs on the machine. I had to switch my PySide6 version to 6.7.1 and make sure everything was working with this version.
• Create a separate venv for compiling, clone pyside-setup 6.7.2, install requirements.
• Add input() to line 132 of venv/lib/python3.11/site-packages/PySide6/scripts/android_deploy.py
• Make dist folder in pyside-setup, download wheels for PySide6 and Shiboken
• Run pyside6-android-deploy with arguments (I already had NPK and SDK downloaded)
• Add requirements to buildozer.spec.
• Download APK on android, install app, run.

The app crashes on startup. I think this may have to do with my project structure, it might not be importing all the modules. In my main.py file, I am adding libraries outside of the directory to PATH. My directory looks like this:

Main project folder
└— Project
|   └— .env
|   └— Project (this was the directory I ran pyside6-android-deploy in)
|       └— main.py
└— Library
|   └— assets
|       └— assets.qrc
|       └— assets.py (compiled from .qrc)
|       └— fonts folder containing .ttf files
|       └— images folder containing .svg files

Here is the log from adb logcat:

You did everything right. It's an error from Android. I would recommend you to use Pyside 6.7.2. I will compile the wheels in the evening (in 3-4 hours) and then you can try with them :)

Edit: I won't make it the next hour. Please wait a bit more, but I'll do it this session

[JonZavialov]

Sounds good, thank you!

[EchterAlsFake]

So I've released 6.7.2 now.

Although when I tried to start my App with them I got an error, but it was different than yours and I think this error is more related to my app being just very weird xD.

But to be honest, this whole Android project is very experimental and still not in a good state. When Qt started this last year in April I really had a lot of hope, but it didn't work. Nothing worked, not even their install script. And it doesn't work 1 year later if you don't know that you need to set the --verbose flag. Hopefully they fix that at some point...

Good luck.

[JonZavialov]

Yeah, lots of potential but the whole release seems very rushed and untested. I don't think anyone is actually using it right now. I tried your new wheels but same thing, app crashes on startup with the same error. I'll tinker some more with my project and see if I can get it to work, thanks so much for your help!

[EchterAlsFake]

Hi, since Qt has released Version 6.8 a lot of things got better. Maybe you could try again xD

(just to remind you lol)
