Alternative for String.join in Android?

I want to concatenate an ArrayList with commas as separators. I found this answer, stating it's possible to use String.join in Java.

When I try to use this however, Android Studio gives the following error:

Cannot resolve method 'join(java.lang.String, java.lang.String, java.lang.String, java.lang.String)'

Is there a good, concise alternative for Android Studio (instead of using a for loop)?

String[] List ={"<html>","<body>","<title>"};
String abc;       
abc =TextUtils.join("\n", List);
textmsg.getText().insert(textmsg.getSelectionStart(), abc);

result:

<html>
<body>
<title>

You can use this

TextUtils.join(", ", your_list);

You can use TextUtils.join instead:

String result = TextUtils.join(", ", list);

(String.join was added in Java 8, which is why you can't use it in Android.)
