Android - EditText to int after pressing button click issue

Is it a proper casting? After pressing button the app is closing. If I toggle comment on second line (height = Integer) then it works fine.

public void onClick(View v) 
{
    EditText tHeight = (EditText)findViewById(R.id.tbHeight);
    height =  Integer.parseInt(tHeight.getText().toString());
}

Full log if you mean this log:

Remember that Integer.parseInt can throw NumberFormatException. That is probably what is happening.

Do you have a number on the EditText? It's likely that if there's a space it won't parse as well. Try this tHeight.getText().toString().trim().replace(" ", ""); to remove any spaces.

Also on the XML layout, make sure to mark the input type as numeric.

And last but not least, make sure to put a try{ }catch(NumberFormatException e){ } to make sure it won't crash
