I have app start with Splash screen then open listactivity rows, clicking on any row will opens an activity containing a textview, two buttons (one of which opens an infinite gallery, the other opens a custom dialog), and menu items (about, preference, exit).
This app runs perfectly on ginger bread but when tested on a galaxy s3 running jelly bean, it opens normally but when you click on one of the listactivity rows it appears to ignore the click. The log cat on eclipse shows :
SPAN_EXCLUSIVE_EXCLUSIVE spans cannot have a zero length
However, there is no force close (the listactivity scrolls normally and the menu items work fine and ).
UPDATE:
I noticed something this application: I created it with eclipse since around one month ago with a name lets say (trip) and today testing (trip.apk) on both ginger bread and jelly bean it works perfectly.
But I wanted to change the name from trip to travel and I did not use Refactor. Instead I created a new project with application name called travel but all other things are the same as the previous app trip including classes, res, and when tested with jelly bean shows:
SPAN_EXCLUSIVE_EXCLUSIVE spans cannot have a zero length
UPDATE 3 :
I SOLVED THE PROBLEM :
i added this line to all TextViews in my app which is :
android:textIsSelectable="true"
and that line lead to rows ignore the click ,
so i removed it and now both old and new app work fine with both API .
UPDATE 4:
the above phrases related to old issue and already solved ,
现在的问题是:
我的应用程序与所有API完美配合,但在测试时:
galaxy S3运行果冻豆也很完美,
但在eclipse中日志猫显示错误:
SPAN_EXCLUSIVE_EXCLUSIVE spans cannot have a zero length
不影响应用程序性能,任何解决该错误的想法.
任何解释都将受到高度赞赏,谢谢.
