I tried to look into the android framework code (link<http://www.google.com/codesearch/p?hl=en&sa=N&cd=1&ct=rc#uX1GffpyOZk/core/java/android/view/LayoutInflater.java&q=lang:java android.view.InflateException Error inflating class java.lang.reflect.Constructor&l=458>). The topmost frame refers to a 'throw' statement(line 512) that is inside a catch of a lower level exception. I can't tell what part of the createView() function throws that lower level exception. I also tried to search around for the error string "Error inflating class java.lang.reflect.Constructor", but couldn't found one with a similar stack trace. (There are known crashes with this error message caused inside android.preference.* package, but mine is a simple widget layout and not preferences, as you might have seen in the XML file I attached earlier.)
I now have 9 reports of this crash and all of them are confirmed to be using Sprint HTC Hero devices. This problem hasn't been reported on any other phone. Is it fair to assume that it's a problem in that particular ROM? If that's so, then what options do I have to resolve this issue - should I wait helplessly for HTC/Sprint's next update? Any suggestions are appreciated.
