Now that I understand your intent creation a little better, and I see that
the intent you are creating is unique from the class in which the code
exists, I am not quite sure how it could be an infinite loop in the
(immediate) way I was thinking.
Reading this code
Intent i = new Intent(this, Select.class);
I have to start thinking there's something wrong with this. I tried to look
up the "Select" class on the android developers site, and couldn't find it.
Is that a class from another of your files? I guess I would wonder if the
code being invoked there, is somehow causing this class to be invoked, thus
causing some kind of loop. I would grep for any reference to your Sheet
class, from anywhere else in your code, and that would likely be suspect.
In general, the below is kind of a side topic, to maybe help you with
generic debugging.
All the Best, Steve.
*Ok... the only thing I can think to really help you is to start taking
advantage of logging. In your import list, I see you don't include the
logger code, so maybe you can give this a shot.
1) in the import list
import android.util.Log;
2) and throughout your code
Log.d( TAG, DebugText );
where TAG is a string that is unique to you, and "DebugText" is something
useful to identify the part of the program you're interested in.
