I'm trying to do a camera application with image processing. Here I tried to convert the image (byte array) to bitmap, but 

BitmapFactory.decodeByteArray

is returning null everytime

this is my code : 

        Log.e("test -> arry byte = ", String.valueOf(byteArray));
        Log.e("byteArray.length = ", String.valueOf(byteArray.length));
        Bitmap bmp = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);
        Log.e("bitmap ici ->>> ", String.valueOf(bmp));

and the following stack trace :

enter image description here

Anyone has an idea ?

  • Can you post your code showing how you get the byte array? In all likelihood it is not a valid image. – rlay3 Mar 18 '16 at 09:30

Bitmap bitmap = BitmapFactory.decodeFile("/path/images/image.jpg");
ByteArrayOutputStream blob = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.PNG, 0 /*ignored for PNG*/, blob);
byte[] bitmapdata = blob.toByteArray();

//if bitmapdata is the byte array then getting bitmap goes like this

Bitmap bitmap = BitmapFactory.decodeByteArray(bitmapdata , 0, bitmapdata .length);
