To mark all url in application authenticate, use of basic authentication could good option.
In Below example I used Username and Password to generate Authentication header .
String authentication = editusername.getText().toString().trim()+”:”+editpassword.getText().toString().trim();
String authHeader =Base64.encodeToString(authentication.getBytes(), Base64.NO_WRAP);
Use this “authHeader” in every call of Url…like this,
httpPut.setHeader(“Authorization”, “Basic “+””+authHeader);
or
httpPost.addHeader(“Authorization”, “Basic “+””+authHeader);
