Html text (or spannable) in a button don't work after migrating to Android Studio

Question

MyButton.setText(Html.fromHtml("*  <small><sup>^</sup></small>"));

With Eclipse :

enter image description here

With Android Studio :

enter image description here

It is the same if i use an other method :

SpannableStringBuilder cs = new SpannableStringBuilder("*  ^");    
cs.setSpan(new SuperscriptSpan(), 1, 4, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
cs.setSpan(new RelativeSizeSpan((float) 0.50), 1, 4, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
MyButton.setText(cs);

Muy buid.graddle configuration is :

android {
   compileSdkVersion 18
   buildToolsVersion "21.1.2"

Thanks for your help !

I'm using html mode. The problem is not in programmation but it is the migration to Android Studio ! — Eric JOYÉ, Dec 13 '14 at 18:31
Not possible imho, what you see is probably not Html version but SpannableStringBuilder, change 1 to 2 and run again — pskink, Dec 13 '14 at 19:00
Just tested on kitkat and it's ok, using android studio of course — pskink, Dec 13 '14 at 19:02
Maybe you see the old apk results, is your apk properly deployed? — pskink, Dec 13 '14 at 19:05

The problem is not migration. I created a new program with AS:

    LinearLayout ly = new LinearLayout(this);

    Button b = new Button(this);
    b.setText(Html.fromHtml("*  <small><sup>^</sup></small>"));

    ly.addView(b);

    TextView tv = new TextView(this);
    tv.setText(Html.fromHtml("*  <small><sup>^</sup></small>"));

    ly.addView(tv);

    setContentView(ly);

Result with Android Studio :

enter image description here

it is working in the textview, but in the button, superscript for "^" character is not present. The same code in eclipse is working well both for the textview and the button.

I'm using AS 1.0.1 and my buid.graddle configuration is :

android {
  compileSdkVersion 21
  buildToolsVersion "21.1.2"

Thanks for your help !

@pskink The problem is the same with a simple html tag : b.setText(Html.fromHtml("A A")); — Eric JOYÉ, Dec 14 '14 at 11:58
The **SOLUTION** : added **b.setAllCaps(false);** Explanations : http://stackoverflow.com/questions/24880388/cannot-lower-case-button-text-in-android-studio?rq=1 — Eric JOYÉ, Dec 14 '14 at 15:14

Try this...

Button byButton = new Button(this);
byButton.setText(Html.fromHtml(" * <small><sup> ^ </sup></small>"));
