Looks good! But I would suggest to either change DESIRED_ANDROID_APPLICATION_VERSION name or add into a comment above information that this is Android Gradle Plugin (AGP) version. Also, instead of vague description for this variable This shouldn't be too old.. I would add a link to the official table of compatibility between Gradle version and Android Gradle Plugin versions: https://developer.android.com/build/releases/gradle-plugin
about:
echo "Android project updated. Run 'git diff' to see the changes or 'git reset --hard' to discard them."
I would prefer 'git checkoout -- .' to clean up the temporary changes, instead of 'git reset --hard' which could cause problems by accident
Hi Andrea!
Thank you for your helpful courses! I have an app almost finished, but I have massive problems with Gradle and have been trying to solve the problems for 4 weeks again and again via ChatGPT or Gemini. But it all goes in circles and I can't find a solution. No matter which solution I try, there are always problems with the apk. Even your script didn't help me.
In the Ios emulator I can run the app. That works. But it's all only finished when I can make the apk. Can you help me or is there anyone who could help me? Best regards Tobias
Thank you for sharing this script!
