I know, the question may seem duplicate but is not. I am using AppCompatTextView from androidX and the documentation says that the AppCompatTextView inherits the TextView's long list of methods. Among them there is setJustificationMode() and getJustificationMode() methods. But still I can't use those methods below API 26. 
@BindView(R.id.textView3) AppCompatTextView mTextView;
@Override
public void prepareUI() {
    mTextView.setJustificationMode(Layout.JUSTIFICATION_MODE_INTER_WORD);
}
I even tried writing it from the XML, but still no success. 
I tried it with app:justificationMode && android:justificationMode...
Is there something that I am doing it wrong or missing?
Here is the link to the AppCompatTextView documentation:
