Converting Byte Array to Bitmap android [duplicate]

Question

I'am trying convert Byte Array to Bitmap to show in imageView in android, I am taking byte data from method but When I run the below function,I am taking null value of Bitmap, how can I take bitmap value from byte[] array

 private CameraProxy.CameraDataCallBack callBack = new CameraProxy.CameraDataCallBack() {

        @Override
        public void onDataBack(byte[] data, long length) {
            // TODO Auto-generated method stub
            Log.i(TAG, "length . " + length);

            Log.i("data",""+data);

            Bitmap bitmap = BitmapFactory.decodeByteArray(data,0,data.length);
            im.setImageBitmap(bitmap);




        }
    };

is it the sdk public? are you sure that the byte array is argb? — Blackbelt

you can't convert just any byte array to bitmap. Are you sure that byte[] data is a bitmap byte array? — Vladyslav Matviienko

how can understand that, it returns me like this "data:{88,84,83,80,82,81, + 1382390 more}" — ridvan

These code works for me.

            bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(),                       
            selectedImage);

            img = findViewById(R.id.imageView);

            //img.setImageBitmap(bitmap);

            ByteArrayOutputStream stream = new ByteArrayOutputStream();
            bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
            byteArray = stream.toByteArray();
