if-else structure not working in android?

The if else structure is not setting correct url even though location and category parameters

are correctly parsed.

private void initView(String location,String category) {

// show progress dialog

dialog = ProgressDialog.show(this, "", "Loading...");

String url;

if(location.toString()=="Jaipur" && category.toString()=="Gardner")

url = "http://192.168.186.1/apps_jaipur_gardner.php";

else if(location.toString()=="Jaipur" && category.toString()=="Mason")

url = "http://192.168.186.1/apps_jaipur_mason.php";

else if(location.toString()=="Jaipur" && category.toString()=="Carpenter")

url = "http://192.168.186.1/apps_jaipur_carpenter.php";

else if(location.toString()=="Jaipur" && category.toString()=="Plumber")

url = "http://192.168.186.1/apps_jaipur_plumber.php";

else

url = "http://sid429.hostei.com/appsonline.php";

Log.d(TAG,location);

Log.d(TAG,category);

Log.d(TAG,url);

FetchDataTask task = new FetchDataTask(this);

task.execute(url);

}
