It looks like mTa.setText(mTxt);
is generating the NullPointerException because the line mTa = (TextView) findViewById(R.id.entry); is not returning a reference to the TextView. This component is in the layout XML, and has an ID assigned (I can see it on the R.java file). Can you think of any reason this would return null? thanks On Jan 13, 9:12 pm, steve_macleod <[email protected]> wrote: > Ok, I removed the second argument, and tried again, same error.
