Kivy/Python code displaying white screen on rpi touchscreen

Asked 2022-Mar-23 at 03:26

I'm having some trouble with some code I wrote that appears to work on the desktop, but when copied to my raspberry pi/touchscreen, I get a purely blank screen. Rpi has kivy installed. Kivy demos work just fine on both systems. Is there a chance there is something with import Window on kivy? Any advice would be greatly appreciated!


EDIT 1: I read online of someone else with a similar issue, needed to add (from kivy.lang.builder import Builder) and (Builder.load_file.py). I added this in the python code, which is letting me see most of the original program. Some of Kivy is showing, though for some reason- the graphic menu.png is missing and so is the textbox/grid layout at the bottom of the page (bottom of the kivy code below). This may be due to my positioning, so I will look into this.
Edit 2: This should be resolved- it was implementing Builder to the python code (correct version seen below). I also discovered- the raspberry pi might have an issue with images named 'menu.png'... Just changed the name of the image and everything was visible. No idea on that one. Thanks for the assistance.

Had the same issue. Solved it by increasing the memory dedicated to the GPU on the Raspberry Pi.


Edit your /boot/config.txt file (sudo required)
Scroll down to the [all] section, and edit the gpu_mem line as follows:
gpu_mem=256
Then reboot your pi.

How to change a KivyMD Menu caller to a Widget in a ScreenManager Screen

Asked 2022-Feb-21 at 18:49

So, I'm working on a simple kivy app and I have three buttons (MDRaisedButton's) which each open the same KivyMD Menu (MDDropdownMenu) on release.



Two of these buttons are in different ScreenManager screens.

The other button is in a GridLayout in the Screen outside
the ScreenManager.


When I open the menu using the buttons inside of the ScreenManager, the menu appears at the button that is outside of the ScreenManager, no matter which button I press.

So how can I change the caller, or the position of the menu when it appears to be that of the buttons in my ScreenManager screens?

Me clicking on the button inside the ScreenManager screen:

The menu appears on the wrong button:

 ...

ANSWER

Answered 2021-Sep-23 at 22:08

I had the same problem and found the problem and a workaround, not the solution though:


The problem lies within the Drawable Object created in the file plyer/platforms/android/notification.py. If you print(dir(Drawable)), you will find no attibute icon (as the error message stated). I don't know why the icon attribute is missing, but you will find there is a presplash attribute instead (which is also a .png file and thus replaceable).
By changing line 100 in the notification.py from app_icon = Drawable.icon to app_icon = Drawable.presplash, I could dodge the error and my app worked perfectly well. You need to change the line in the correct file though, which is located at ProjectName/.buildozer/android/platform/build-armeabi-v7a/build/python-installs/projectname/plyer/platforms/android.

Kivy widget generation very slow

Asked 2022-Jan-25 at 08:32

I'm making a kivy app to find the rhyming words for a word entered by the user. It displays all the rhyming words as OneLineListItems in an MDList which is inside a kivy RecycleView. On clicking on one of these OneLineListItems it displays the definition of the word on the right-hand side of the screen. However, when I click on a OneLineListItem its definition takes very long to appear and sometimes it lags so badly that the app closes. Am I doing something wrong or is it just my computer?

How to build an .aab using Buildozer via Docker?

Asked 2021-Nov-26 at 13:34

I have just seen that support for AAB files have just been introduced in Python for Android (p4a). Considering that, fom August 2021, new apps are required to publish with the Android App Bundle on Google Play, this is a crucial addition for any Python dev working on Android apps.


Since I'm currently using Buildozer via Docker, I'd like to know which are the steps to make it generating an .aab instead of (or along to) the traditional .apk
For the sake of clarity, here is what I use to run Buildozer from inside a container (using Docker for Windows) to make the .apk file:

ANSWER

Answered 2021-Nov-26 at 13:34

The community has finally completed the AAB support for Buildozer. Although it is still a pending pull request, it is already possible to create the AAB, and I have figured out how to do it using Docker.


I have found two very interesting gists that helped me a lot (this one about creating an AAB with Buildozer on Ubuntu, and another one about signing an AAB on the same platform). However, I have run everything on Windows via Docker, so I think it is a good idea to share how I did it.

Clone the feat/aab-support branch of the Buildozer repository in your local machine:

ANSWER

Answered 2021-Oct-09 at 22:10

I do not know why it is getting stuck, but what I see is that you are using python 3.10, which is so fresh, that I had to go check to see if it is already released (it is! 5 days ago!).


kivy does not have a wheel for 3.10, so it is trying to build one from the source, and crashes because of the missing kivy-deps.gstreamer-dev dependency, which is binary only and not available for python 3.10.
I deduce, that it is unlikely that you will be able to install kivy with python 3.10. Try 3.9?
