Python Code to Android APK with Flet
Creating an Android APK from Python code can be achieved with the help of tools like Flet. Flet is a command line tool that helps convert Python code into Android APK files by wrapping the code in a WebView and providing an interface to interact with it.
To get started, first install Flet on your system by running the following command:
pip install flet
After installing Flet, you can use it to convert your Python code into an Android APK by running the following command:
flet my_python_code.py
This will create an APK file that can be installed on an Android device or emulator for testing.
Test APK in Virtual Emulator
To test the APK file in a virtual emulator, you can use Android Studio’s built-in emulator. Follow these steps to test your APK file in the emulator:
- Open Android Studio and create a new project if you haven’t already.
- Import the APK file into the project’s directory.
- Run the emulator by clicking on the AVD Manager icon on the toolbar.
- Create a new virtual device if needed and start the emulator.
- Drag and drop the APK file into the emulator to install it.
- Open the installed app in the emulator to test its functionality.
By following these steps, you can easily test your Python code converted into an Android APK using Flet in a virtual emulator.
Now that you can build an Android APK, what do you think of additionally publishing your application to the web platform?
Of course, I got you covered 🙂: https://youtu.be/CLzKZlv1IAA
How to change logo in flet python apk ?
does this need a Android sdk？
when I run flet build apk, this error appears "OSError: [WinError 193] %1 is not a valid Win32 app"
Nice, and what if I have an .kv file to feed my main.py project?
BUILD FAILED in 5m 26s

84MB lol. We're better off doing Java/Kotlin/flutter/dart the hard way. Python just take shortcuts to do very little lol
'flutter' command is not available in PATH. Install flutter SDK
when i run flet build apk show this error
{Because myapp depends on flutter_test from sdk which doesn't exist (the Flutter SDK is not available), version
solving failed.
Flutter users should use `flutter pub` instead of `dart pub`.

Try `flutter pub outdated` for more information.
The plugin `flutter_native_splash` doesn't have a main class defined in

splashFlutterNativeSplashPlugin.java or
C:UsersalikhAppDataLocalPubCachehostedpub.devflutter_native_splash-2.3.7androidsrcmainkotlinnetjonhansonflutter_nativ
e_splashFlutterNativeSplashPlugin.kt. This is likely to due to an incorrect `androidPackage: net.jonhanson.flutter_native_splash` or
`mainClass` entry in the plugin's pubspec.yaml.
If you are the author of this plugin, fix the `androidPackage` entry or move the main class to any of locations used above.
Otherwise, please contact the author of this plugin and consider using a different plugin in the meanwhile.

PS C:UsersalikhOneDriveDesktopVectras> flutter pub outdated
Error: No pubspec.yaml file found.
This command should be run from the root of your Flutter project.
When we use any external package like mysql.connector then after apk build it shows error kindly suggest solution
hi I'm having a problem in flet build apk
After installing on my android app, it sometimes stops working, what do you think is the cause?
fantastic video! It will be great to see like a noteapp with fastapi to see how flet endpoints work..
Why a simple app size becomes 84 MB ??
Thanks so much. I would love a tutorial on integrating existing flutter packages into a flet build. Flutter and Dart are a whole new thing (which is why i was attracted to using Flet in the first place, to avoid learning those lol).
great!

Great work bro 👊🏾
