android - Multiple task with one button

The stack trace clearly tells you where the error is @ NavigateImage.java Line#31

Looking at code, it seems like you are passing wrong resource id in following line. May be you meant to use R.id.edit_destination

EditText e = (EditText)findViewById(Edit_current);

So, I suspect, it is crashing from

final String current = e.getText().toString();

Because it can't find the EditText e.

NOTE: In future as best practice, please use descriptive variable names.
