if You have Array inside String.xml You can use this: BTD.setDropdownData("@array/*****"); if you don't have, you want set data from Your Database, You must create a method with Object return.....

@Asad-ls you just add network option file to res/xml like this your domain without http:// and add this line to manifest/application tag android:networkSecurityConfig="@xml/network_security_config"
