EntityUtils is static helpers for dealing with entities.
http://www.developer.android.com/reference/org/apache/http/util/EntityUtils.html‎
String result = EntityUtils.toString(response);
if(result >="0"){
//do somthing
}
response.toString()
try that, you should also look at writing your questions more formally.

My error is :
weight = Float.parseFloat(etWeightBMI.getText().toString()); error is (1228): java.lang.NumberFormatException: Invalid float: ""
Before Parsing you should check
if(TextUtils.isEmpty(etWeightBMI.getText().toString()))
{
//do your job
}
etWeightBMI.getText().toString(); returns blank. Thats why you get the NPE.
This line returns null.
etWeightBMI.getText().toString();
Do this with validation like below:
if(etWeightBMI.getText().toString().trim().length()>0){
weight = Float.parseFloat(etWeightBMI.getText().toString());
}

I want to dial a special number like
*123#
which is a network request and get result sent by network.
Is this possible? How can I do it?
Yes you can do this:
Intent calling=new Intent(Intent.ACTION_CALL);
if ( phno.contains( "#" ))
phno = Uri.encode(phno+"#");
calling.setData(Uri.parse("tel:"+( phno ) ) );
startActivity(calli);
Note:
Here phno is String that contains phone number like *123# or 123456789

This is my code:
blanks=new EditText(this);
String values =blanks.getText().toString();
answers.put(relative.getId(),answer);
if(answer[0].equals(values)) {
Toast.makeText(this,"Match!", Toast.LENGTH_LONG).show();
}
Your code makes no sense. You crate a new EditText field, and then immediately get the text. But this will always be null.

I am trying to loop through a vectors elements and trying to find out if a position in the vector is equal to null...
if(_vecForShapes.get(i)!=null)//this line works fine but when it gets to a position where it is null it gives me an error? Any ideas?
{
}
Thanks!
Are you sure that it is get(i) that is null, and not that you have exceeded the number of items in _vecForShapes? It is much more likely that the _vecForShapes.get(i) is throwing an error than the comparison to null.
What type does get(i) return?
