What’s new in this release?
Aspose development team is pleased to announce the new release of Aspose.Cells for Android v7.0.0. Aspose.Cells for Android provided memory optimization settings for newly created worksheets by exposing the setMemorySetting method for the Workbook.Settings class. The previously provided approach was useful for minimizing the overall memory cost while working with existing large Microsoft Excel spreadsheets containing huge datasets. With release 7.0.0, we have enhanced this feature for existing worksheets by exposing a similar method for the Cells class. Now you may use setMemorySetting method provided by the Cells class to cope with the memory issues for situations where large data sets have to be built in memory. The setMemorySetting method accepts a parameter of type MemorySetting with the default value NORMAL. In order to properly utilize this newly introduced feature, memory optimization settings have to be explicitly specified for existing worksheets. Please check the detailed technical article on how to optimize the memory while working with large data sets from our documentation. We have also enhanced the CellsException class to identify potentially damaged or corrupted files when loaded with the Workbook constructor. With the new enhancements integrated, Aspose.Cells for Android API now throws an error of type CellsException whenever it encounters a damaged file. Aspose.Cells for Android 7.0.0 has also provided fixes for several important issues. For example, problems with converting Excel files to PDF format, rendering & manipulating charts, retrieving & removing OLE objects. Moreover, we have improved the overall performance as well as the accuracy of results for the formula calculation engine when working with Excel formulas.
