Answer 1

you should wrap the Double.parseDouble.. statements in a try/catch clause, to catch any NumberFormatExceptions, and set other values where they fail

try{
    etKids = Double.parseDouble(noKids.getText().toString());
} catch (final NumberFormatException e) {
    etKids = 1.0;
}
try{
    etGumballs = Double.parseDouble(noGumballs.getText().toString());
} catch (final NumberFormatException e) {
    etGumballs = 1.0;
}
