Question

String bb = c.getString(c.getColumnIndex(JR_Constants.IMAGE_97)); Log.v(TAG,bb); Bitmap theImage = BitmapFactory.decodeByteArray(bb, 0, bb.length); myImage.setImageBitmap(theImage); what i'm doing mistake here.

Answer 1

You need to convert the String to a ByteArray. Basically just do bb.getBytes() instead of passing bb

String bb = c.getString(c.getColumnIndex(JR_Constants.IMAGE_97));
Log.v(TAG,bb);
Bitmap theImage = BitmapFactory.decodeByteArray(bb.getBytes(), 0, bb.length());
myImage.setImageBitmap(theImage);

I just want to note that bb.length should be bb.length()
