A strange NullPointerException
<p>I'm working on an android app where I have only 2 activities... The first activity call the second activity.. At the start my app initialize a global ArrayList with some informations taken over the internet... then a thread starts and every 10 seconds fetch the same informations and updates the ArrayList ( thread doesn't allocate it again )... When I start the second activity, this one fetch the ArrayList at the start... this works in my emulator and my phone ( htc wildfire ) but for someone that has my app, this works only for about 20 minutes, after that the ArrayList become null... why this?? oh btw, the ArrayList is a CopyOnWrite ArrayList, if could be important...</p>

<p>Thanks in advance for any reply,</p>

<p>=.4.S.=</p>
