Quero inserir uma imagem PNG na minha planilha do Excel usando o Apache poi.

Para fazer isso, eu uso este código:

//add picture data to this workbook.
InputStream is = new FileInputStream("/sdcard/MYAPPFOLDER/logo_app.png");
byte[] bytes = IOUtils.toByteArray(is);
int pictureIdx = workbook.addPicture(bytes, Workbook.PICTURE_TYPE_JPEG);
is.close();

CreationHelper helper = workbook.getCreationHelper();

// Create the drawing patriarch.  This is the top level container for all shapes. 
Drawing drawing = sheet.createDrawingPatriarch();

//add a picture shape
ClientAnchor anchor = helper.createClientAnchor();
//set top-left corner of the picture,
//subsequent call of Picture#resize() will operate relative to it
anchor.setCol1(0);
anchor.setRow1(0);
Picture pict = drawing.createPicture(anchor, pictureIdx);

//auto-size picture relative to its top-left corner
pict.resize();

Mas, na primeira vez, tenho um erro que resolvi adicionando esta bibliotecacommons-codec-1.8.jar e agora eu tenho esse erro:

02-21 10:10:51.466: E/AndroidRuntime(31691): FATAL EXCEPTION: main

O que aponta para esta linha:

pict.resize();

Como posso corrigir isso?
