it fixes the issue Does the textID.getText() actually is a parseable double string? For instance "10.1" do but "10.1 " no.
Always I did this kind of conversion I use trim() to remove this extra white spaces as follow:
code :
String stringValue = textID.getText();
if(stringValue != null) {
    stringValue = stringValue.trim();
double doubleValue = Double.parseDouble(stringValue);

wish helps you You'll want to make answer a double as well, since you're doing calculations. It's only at display/formatting phase where you should convert to a String.
You should put only the calculation part inside the if (i.e. answer = first + second, with answer being a double), and afterwards convert it to a String to avoid duplicate code.

Does that help A couple things..
First I would do some reading on the differences between the single quote and the double quote's behaviors. Just so going forward you have a basis for the differences between the two.
code :
"hello my name is "steve""
"hello my name is "  steve ""
$text_data = "hello my name is 'steve'"; 
$final_text = str_replace("'",'\"',$text_data);

wish help you to fix your issue The image you uploaded shows you are actually running multiple threads, but the culture is only being set for the current thread.
To overcome this you can assign the desired culture to a variable and use it inside Task.Factory.StartNew. You can do something like this:
code :
var culture = new System.Globalization.CultureInfo("en-US");
return Task.Factory.StartNew(() => 
    // use culture here
    Thread.CurrentThread.CurrentCulture = culture;

    // your actual code here
    String i = "0.48,trx/btc,coss,hitbtc2,0.0000062000 / 0.0000066000,0.0000061502 / 0.0000061701,,0.48%";
    double test = double.Parse(i.Split(',')[0]);
// put this at the top of your file
var culture = new System.Globalization.CultureInfo("en-US");

// use this inside Task.Factory.StartNew
double test = double.Parse(i.Split(',')[0], culture);
double test = double.Parse(i.Split(',')[0], CultureInfo.InvariantCulture);
