I have a very large array (800 lat longs).

Could encoding work?

Probably not as if you use floats, those are already a simple object

Ah

It depends on the data. I guess the points are close to each other, so in theory you should need less bits to store the delta between them instead of absolute value, but then you'll need to do some tricky calculations, probably fixed point aritmetic, etc...

That would still be a simple object (32 bits that fits in the object itself),  Boolean, Number and Float are simple objects.  

doubles, for example are complex objects, where the object contains a pointer to the value, not the value itself.,

You'd lose precision. I have a DF that works on CIQ 1 derives with a max of 16k, where I do store 200 lat/lon paird (floats).  In this case the simple solution could be to have the app as a device app (124k) instead of a widget (60k)

Well the only reason I chose widget vs an app is because I aleays forget to close apps, widgets do that for me. There isn’t a way to have an app close after a set amount of time no?

timer and sys.exit()

Hmmm, interesting…Means Ican make it close after a longer period of time but still not forget it. I assume it preserves your data (e.g active route?)
