Android Application Development Tutorial - 74 - MotionEvents and Motion Actions

[onthatweagree]

I found finally in the OnCreate I had not removed the "Bitmap" declaration on the variables moved into the class... ignoring teh warnings about "local variables not used" finally gave it away... the FORCE QUIT mystery solved by this novice "Java" developer! :P By the way - this series and Travis - deserves a reward - awesome work and build up for a great learning experience!!!!

Ugh, I hate that while(true) you have to do the join. Literally useless. Here is what it's going to do.

first iteration: Oh hey, I'm true, I'll execute my body. Join, catch if needed break; aka, cease running the loop.

second iteration: doesn't happen, loop already broke >.<

Nice!

ok I kept getting force closes on this tutorial. I followed the tutorial to a t but it still wasn't working.

My fix was: (please tell if this is right or not?!)

I moved where I was setting up the bitmaps

from my "onCreate" method in the "GFXSurface" Class

to the "run" method in the "MyBringBackSurface" Class

Can anyone tell me why this works?

Thanks for tutorials Travis!

@gearoidmocathain

It still didn't work for me :|

Where exactly in the "run" method did you set up the bitmaps?

mhh After this tutorial, the View is black and no touch-action is performed? What can be the problem?

@klofisch

couple of problems I had was.... when i copy n pasted my .png file it made me force close...so instead of copying n pasting thru folder .. I imported it in my drawable from eclipse.....it solved my first problem....then other was while copying canvas if(x!=0 ...) statement.... I forgot to change following x n y to sX,sY,fX n fY...so double check your code again n again .....

@sweet2smart I checked it several times. Finally i copied from the website to see if its something general. But it wasnt. Now i am at Tut #113 :) SQLite was what i am waiting for the most (time :D ) .
