The main Activity in my Android app has a Gallery widget that loads XML layouts (containing TextViews and Images) through an efficient ImageAdapter. For the most part this works fine and I haven’t had any problems on any of my devices or the emulator, but I have seen the following error in my logs. It looks like this is affecting less than 1% of users, but I’d like to know what’s causing it, how to resolve it, or at least “catch” it and resolve gracefully. Any ideas?
java.lang.NullPointerException at

I get this problem several days ago, please check your own gallery’s adpater check its getView() methods,see if you return null in some if-cases,just replace return null with new View(context) (or other view but null) will simply solve this problem.Good luck
