Decode HTML entities in android
The Html class is supposed to do that, however it is said that everything is not supported. It always worked for me but I never had ö so I can't tell for this one.
Try Html.fromHtml(yourStr) to get the decoded string.
Html.fromHtml(String html) is deprecated after API v24 so this is the correct way to do it
if (Build.VERSION.SDK_INT >= 24)
{
textView.setText(Html.fromHtml(htmlString , Html.FROM_HTML_MODE_LEGACY)));
}
else
{
textView.setText(Html.fromHtml(htmlString));
}
