[Android] Aplikacija se zruši

[Android] Aplikacija se zruši

messi ::

Pozdravljeni,
Napaka se pojavi, ko sem spremeniti velikost črte in nato poskusil nekaj narisati, nato se mi je aplikacija sesula. Sicer mi je javil napaka ne tih dveh delih ampak meni ti dve napaki bolj malo povesta:

_panel.onDraw (c);
in
Oblika currentGraphicObject graphicobjects.get = (i);


Napake:

zgleda da v for loopu gres enkrat prevec, poglej kolk je vrednost
number_of_graphicObjects


ker array je dolg 1, ti pa hoces dostopat do drugega elementa (idx 1)

g333kk ::

Zanimivo sva z messijom poskušala povečat števec pa še tam kjer napako javi in pa tukaj
Shape currentGraphicObject = graphicobjects.get(i);
povsod se crasha zadeva ..
        		for(int i = 1; i<number_of_graphicObjects; i++){
	        		
	        	

Sem prestavil pa je enako.. čudno to..

postavi breakpoint pa povej kolk je vrednost number_of_graphicObjects in kaksna je vsebina graphicObjects

g333kk ::

Takole number_of_graphicobject je le nek števec, ki za vsakega dodanega oblike,črte karkoli doda 1 številko, ..
