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  input = EditTextinput.getText().toString();
input = input.replace(" ", "");

Sometimes you would want to remove only the spaces at the beginning or end of the String (not the ones in the middle). If that's the case you can use trim:

input = input.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+", "");

Try this:

String urle = HOST + url + value;

Then return the values from:

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

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

o/p: Application

Note: White space ,blank space are trim or removed
