Checking null String in android

Question

I am developing an android application.I am getting a String value as null from webservice. I am fetching the value and storing it in a String variable. Then when I print the value using Log, like Log.i("tag", "````!!!cell >>"+cell);, I an getting null printed in the screen. Now what i need is that I need to check the variable for 'null' and I want to display a textfield with no value if it is 'null'. I am using the following statement for checking

if(!cell.equals(null) || !cell.equals("")) {
  _______
} else {
  _______
}

But the control is not going inside the else part if the value us 'null'

Please give me a solution.

Thanks in advance.

Answer 1

when cell is null , and you are trying to invoke a method on it, you will hit by a null pointer exception.

I'd say

if(cell !=null  &&  !cell.isEmpty()) {
  _______yes, disply
} else {
  _______nope, some thing wrong
}

Answer 2

its not equals(null) its

if(cell != null || !cell.isEmpty())

Answer 3

Try TextUtils.html#isEmpty(java.lang.CharSequence)
