AndroidX app crashed on older Android versions using the library V1.2

[chanont-poon]

I've just updated the library to V1.2 and it still crashes on older Android versions. Tested on Emulator and phone with Android 5.1.1. This issue seems to be caused by a bug in androidx.renderscript library itself, as reported in this issue tracker: https://issuetracker.google.com/issues/119582492

App Config

buildToolsVersion '28.0.3'
defaultConfig {
        minSdkVersion 19
        targetSdkVersion 28
        renderscriptTargetApi 19             // Crashed regardless of adding this config or not
        renderscriptSupportModeEnabled true
    }

Unfortunately, my merge request has not been added, this error is because of not using the base script rendering class in package android.renderscript.*. The current version now is using androidx or support package, and caused the problem.

I've made some changes, can you try v1.2.1. @smarteist I didn't merge your code because I want to keep it compatible with both AndroidX and support library.

@mmin18 I've tried v1.2.1, and it seems to have fixed the issue. Thanks for the swift response.
