widget does not shown when minSdkVersion changed from 16 to 17

[filamoon]

It was working fine when minSdkVersion was 16. After changed to 17 (everything else is the same), the html widget does not show at all.

widget version: 0.5.11 and 0.5.8.

snippets from android/app/build.gradle:

compileSdkVersion 29
    minSdkVersion 17
    targetSdkVersion 27

buildTypes {
    release {
        signingConfig signingConfigs.release
        minifyEnabled true
        shrinkResources false
        useProguard true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
