My app keeps saying "unfortunately it has stopped". I don't know why it is crashing

Question

In my activity, the user can input numbers into a EditViews, then click a button to calculate, the result is displayed below. However, if a user edits an EditView, clicks calculate, then goes back to edit an EditView again, the app crashes when the user clicks calculate to recalculate a new total.

I think the crash log is fairly self-explanatory: you have a `NumberFormatException`. It doesn't like special characters like `$` or `.` when it is expecting an `int`. — CzarMatt, Jun 24 '16 at 17:47
As @CzarMatt said your issue is rather self explanatory. You are trying to parse a number but you are inputting special characters and not just numbers. If you put 19.00 only I am rather confident your code will run fine. — basic, Jun 24 '16 at 17:53
You should read the stack trace before asking! $19.00 is not an int. — Tristan Richard, Jun 24 '16 at 18:30
@Lal line 165 is Integer valuesubtotal = Integer.parseInt(subtotal.getText().toString()); — Casey, Jun 26 '16 at 23:12
EditText sand1; finds it in xml---- sand1= (EditText)findViewById(R.id.sand1); get entered texts from the edittexts,and convert to integers. Integer value1 = Integer.parseInt(sand1.getText().toString()); then this-- Double calculatedValue1 = (9.5*value1); then set the value to the textview, to display on screen. result1.setText("$"+ String.format( "%.2f", calculatedValue1 )); this is the entire app, i cant find my problem. i am so bad at this so i know there is a problem staring me in the face but i cant find it @Lal — Casey, Jun 26 '16 at 23:16

You are getting this exception because you trying to parse string into integer, but string has dollar sign. Tri to u0get rid of that sign str.substr (1, , str.size ())
