Anything below froyo can't read method in 3rd party library

Question

I'm using the jexcel api in my android application. It works great on devices running Android 2.2, but any other device just gives a blank String when I try to get the contents of a cell.

I've narrowed the thing thats not working to the Cell.getContents() method in the jexcel api. All android version below 2.2 are able to get the workbook, get the sheets, get the number of sheets, and they can get the cells, but when trying to get the contents within that cell, it return a blank string.

Is there something wrong with the library, or is it an android problem

Answer 1

My guess is that FroYo added in support for some new Apache Harmony class or method (JavaSE-compatible) that JExcel depends on. In earlier versions, JExcel happens to catch the exception that's thrown and quietly fail. However, this is just a guess.

Since JExcel is open source, you could examine the source code to that method and see what turns up. Or, you could temporarily add the JExcel source code to your project (since I'm guessing you're using a JAR right now), and you'll probably get a compile-time error regarding the missing class or method.

This is all a guess, though.
