  2. Change hostname in Melofy app when sending POST request.


Building and Releasing the APKs

NOTE: If release builds on Android fail and mentions flutter_ffmpeg, make sure that mavenCentral() is defined as a repository in your build.gradle and it is listed before jcenter().

  1. Clear build cache
flutter clean
  1. Get depenedencies listed in pubspec.yaml
flutter pub get
  1. Build APKs by splitting them per Application Binary Interface (ABI)
flutter build apk --split-per-abi

Testing the App

  1. Find out your device's CPU architecture.

NOTE: Refer to this article to find out your device's CPU architecture.

  1. In Melofy's latest release, expand the Assets section.

  2. Download the specific release APK based on your device's CPU architecture and install it.

  • For ARM, use APK ending with armeabi-v7a.apk
  • For ARM64, use APK ending with arm64-v8a.apk
  • For x86_64, use APK ending with x86_64.apk

Or, you can download the fat APK that can be installed on ARM, ARM64, and x86_64.

  • The Fat APK is the APK ending with fat.apk

WARNING I: There is no apk for x86 Android. This is because Flutter does not currently support building for x86 Android. Refer to this issue on Github.

WARNING II: These builds are intended for testing purposes only. Usage outside of testing may cause unexpected crashes and performance lags.
