The relevant code:
File file = new File (Environment.getExternalStorageDirectory ()
. ToString ()
+ File.separator
+ "Mldndata"
+ File.separator
+ "SAT_2011111TO115_3B_CHL.BMP");
try {
InputStream is = new FileInputStream (file);
bmp1 = BitmapFactory.decodeStream (is);

} Catch (Exception e) {
/ / TODO: handle exception
}
chlmapImageView.setImageBitmap (bmp1);
