To build for very old Android versions, the problem surfaces that recent Android build tools use AAPT2, which uses UTF-8 instead of UTF-16 in the resources.arsc file. This causes it to not work on Android versions before Android 2.1, when UTF-8 support was added.

I believe this is the max version of tools:

• Compile SDK 29 (Target SDK can be higher)
• Android Studio 4.1.3
• Gradle 4.10.3
• Android Gradle Plugin 2.3.3

(I'm not really sure if really nothing can be upgraded, but this is what I use)

I tried to downgrade little-file-explorer, but was not successful in building.
