Question

An app published on market has an error:

java.lang.NumberFormatException

below the stack.

Is the cause this code?

fade = Integer.parseInt(ListPreference);

I see “OTHER” devices has affected by this crash. Any idea?

==> it seems you are trying to parse an empty string. You should include the parsing operation in a try/catch block and deal with malformed inputs.
