If you change android:versionCode="224" and android:versionName="2.2.4" in AndroidManifest.xml you have to change this in build.gradle file too.
Click on build.gradle in package explorer tree change your new version name and code:
Click on build.gradle in package explorer tree change your new version name and code:
defaultConfig {
applicationId "cz.okhelp.pocasiwidget"
minSdkVersion 11

}
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
