┌─ Flutter Fix ─────────────────────────────────────────────────────────────────────────────────┐
│ The plugin record_android requires a higher Android SDK version. │

│ Following this change, your app will not be available to users running Android SDKs below 23. │

In my mind, I had encountered this problem before, and later "FeodorFitsner" helped to solve it. |

I solved your problem by using --template option and changing pubspec.yaml to latest flet version, and changing android\app\build.gradle |

Ok that was actually a bad solution, I used main branch instead of 0.22.1 branch. While it did compile under main, flet_video did not work on android using it. When I checked out 0.22.1 branch and changed minSdkVersion version to 23 I started getting errors: |

Alright after reading over record pub.dev etc pages, they moved the minimum sdk to 23, I think the only way to really solve this is force going back to versions using sdk 21 till flet team can make minsdk 23 for record work, so solution is as follows: edit pubspec.yaml and add following to fix record_audio and video on flet version 0.21.1: This now compiles to apk fine for both video and record_audio without issues.... |

Thank you for informing me, I am very grateful. Additionally, should I update Flutter to the latest version? The version I am currently using is 3.19.3. Should I place the pubspec.yaml file in the directory of the file to be packaged? |

syleishere, I am still unable to successfully create the APK file. I think I might have made a mistake in the "pubspec.yaml" file. Could you tell me the correct file path for "pubspec.yaml"? Or do I need to add some parameters to the "flet build apk --include-packages flet_audio flet_audio_recorder" command? Please provide guidance. |

After following the above steps, the program can be successfully packaged as an apk file and installed on the tablet.
Friends in need can refer to the above steps to handle it.
However, some of the functions that I could execute before are now unavailable and are being debugged.
