How can I send text with emoji from Android app to server and save it correctly in MySql database?

You can use StringEscapeUtils Apache Library https://commons.apache.org/proper/commons-lang/download_lang.cgi
For saving the unicodes in database you have to encode them. So send your unicodes to server by encoding like
StringEscapeUtils.escapeJava(/* string message*/)
For displaying the encoded unicode in android
StringEscapeUtils.unescapeJava(/* string message*/)
