Issue: Cropped superscript index between tags sup /sup is not correctly visible in TextView or View as Button.

String s = "10<sup>12 </sup>";
textView.setText(Html.fromHtml(s)); // 12 will cropped 
// solution:
s = "10<sup>12 </sup>\t	"; // add behind ending of sup tag the tabulator \t, 
// but not char \t but only press to TAB key!!! in source code
textView.setText(Html.fromHtml(s)); // 12 is visible correctly

Set in AndroidManifest.xml android:theme="@android:style/Theme.NoTitleBar" AndroidManifest.xml example source code.
AndroidManifest.xml

<manifest xmlns:android="//schemas.android.com/apk/res/android"
    package="com.myexample.without_titlebar">
    <application android:label="My app">
      <activity android:name="NoTitleBar"
        android:theme="@android:style/Theme.NoTitleBar"
        android:screenOrientation="portrait"
        android:configChanges="keyboardHidden|orientation">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
