BlackBerry: Creat Bitmap object from SD card image - blackberry

Question

Can we create an Bitmap object from the SD card image file path ?
I have written a sample method to create it. Is it right approach?
public Bitmap createBitmap(String filepath){
try {
// filepath e.g. "file:///SDCard/test.jpg"
FileConnection fc = (FileConnection)Connector.open(filepath);
byte[] responseData = new byte[10000];
InputStream inputStream =fc.openDataInputStream();
int length = 0;
StringBuffer rawResponse = new StringBuffer();
while (-1 != (length = inputStream.read(responseData))) {
rawResponse.append(new String(responseData, 0, length));
}
byte[] dataArray = rawResponse.toString().getBytes();
Bitmap bitmap = Bitmap.createBitmapFromBytes(dataArray, 0, dataArray.length, 1);
// EncodedImage.createEncodedImage(dataArray, 0, dataArray.length);
return bitmap;
} catch (IOException e) {
return null;
// TODO Auto-generated catch block
// e.printStackTrace();
}
}

public final class MyScreen extends MainScreen {
Bitmap bit, bit1;
BitmapField bitf[] = new BitmapField[12];
FileConnection fc;
FlowFieldManager grid;
String[] imgpath = { "bharat.png", "fighter1.jpg", "fighter2.jpg",
"fighter3.jpg", "fighter4.jpg", "fighter5.jpg", "fighter7.jpg",
"fighter8.jpg", "fighter9.jpg", "fighter10.jpg", "fighter11.jpg",
"fighter6.jpg" };
String compath = "file:///SDCard/";`enter code here`
public MyScreen() {
grid = new FlowFieldManager();
try {
setTitle("Bharat Title");
for (int i = 0; i < imgpath.length; i++) {
fc = (FileConnection) Connector.open(compath + imgpath[i]);
DataInputStream in = fc.openDataInputStream();
int size = (int) fc.fileSize();
byte[] bb = new byte[size];
bb = IOUtilities.streamToBytes(in);
bit = bit.createBitmapFromBytes(bb, 0, bb.length, 1);
bit1 = new Bitmap(120, 120);
bit.scaleInto(bit1, Bitmap.FILTER_BOX);
bitf[i] = new BitmapField(bit1, FOCUSABLE);
grid.add(bitf[i]);
fc.close();
}
}
catch (Exception ex)
{
ex.getMessage();
}
finally {
try {
fc.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
add(grid);
}
