Removing spaces from string

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+", "");

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();

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");
