App crashes(SIGABRT) on Android 4.4 (kitkat)

Overview

• Upgrade apps that were previously created with Unity 5.6.5p1 to the environment of Unity 2018.4.1f1.(For Android 64bit support).

• When I confirmed the operation with Android 4.4 (kitkat), SIGABRT occurred at the timing of transitioning the scene, and the application crashed.

  ---

Working environment

• Unity Version

  • Unity2018.4.1

• Unity Settnings

  • Platform：Android

  • Scripting Backend：IL2CPP

  • Target Architectures：ARMv7、ARM64、x86

• Smartphone used

  • Model number ：SHV31

  • Android Version：Android 4.4.4

    ---

Occurrence timing

Occurs when transitioning between specific scenes

(100% occurs when transitioning between scenes)

Changes due to changes in Unity build settings

• Remove ARM64 from Target Architectures (= non-64bit)

  • → Error occurrence (no improvement)

• Change Build System from Gradle to Internal

  • → Error occurrence (no improvement)

• Change Scripting Backend from IL2CPP to Mono

  • → Error occurrence (no improvement)

  • After executing Export Project, build on Android Studio

    • → Improvement (no error)

  • Build execution with Development Build

    • → Improvement (no error occurred, why?)

  • I don't know why the problem doesn't occur, especially when working with apps created with Development Build.

    ---

Others (something already known)

• No problem with Android 5 (or newer OS) devices

• Updated to the following version and confirmed the operation. However, the phenomenon was not improved.

  • → Unity 2018.4.7

  • → Unity 2019.2.1　

• I have created an iOS app using the same source code, but there is no problem with iOS
