[android] Removing spaces from string

I'm trying to remove all the spaces from a string derived from user input, but for some reason it isn't working for me. Here is my code.

public void onClick(View src) {
    switch (src.getId()) {
        case R.id.buttonGo:
            String input = EditTextinput.getText().toString();
            input = String.replace(" ", "");
            url = ur + input + l;
            Intent myIntent = new Intent(start.this, Main.class);
            myIntent.putExtra("URL", url);
            start.this.startActivity(myIntent);
            break;
        }
}

String res =" Application " res=res.trim();

o/p: Application

Note: White space ,blank space are trim or removed

Try this:

String urle = HOST + url + value;

Then return the values from:

urle.replace(" ", "%20").trim();

When I am reading numbers from contact book, then it doesn't worked I used

number=number.replaceAll("\\s+", "");

It worked and for url you may use

url=url.replaceAll(" ", "%20");

I also had this problem. To sort out the problem of spaces in the middle of the string this line of code always works:

String field = field.replaceAll("\\s+", "");
