From June 2018 Android officially started supporting this feature for Android 4.0 (API level 14) and higher.
Check it out at: Autosizing TextViews

With Android 8.0 (API level 26) and higher:

Programmatically:

setAutoSizeTextTypeUniformWithConfiguration(int autoSizeMinTextSize, int autoSizeMaxTextSize, 
        int autoSizeStepGranularity, int unit)

textView.setAutoSizeTextTypeUniformWithConfiguration(
                1, 17, 1, TypedValue.COMPLEX_UNIT_DIP);

Android versions prior to Android 8.0 (API level 26):

Programmatically:

TextViewCompat.setAutoSizeTextTypeUniformWithConfiguration(
TextView textView, int autoSizeMinTextSize, int autoSizeMaxTextSize, int autoSizeStepGranularity, int unit) 

TextViewCompat.setAutoSizeTextTypeUniformWithConfiguration(textView, 1, 17, 1,
TypedValue.COMPLEX_UNIT_DIP);

Attention: TextView must have layout_width="match_parent" or absolute size!
