java - Reading an image as byte array with Android: skImageDecoder::Factory returned null -

i have spring mvc web service returns image byte array. output in json format. format png here's code snippet image.

bufferedimage img = imageio.read(new file(caminho.replace("/", "//")));                 imagem = ((databufferbyte) img.getraster().getdatabuffer  ()).getdata(); 

when run server, output:

[{"id":0,"caminhomdpi":null,"caminhohdpi":"c:/users/marcos/pictures/postos/drawable-

mdpi/esso_logo.png","caminhoxhdpi":null,"caminhoxxhdpi":null,"imagem":"aaaaaaaaaaaaaaaaaaaaaaa

aaaaaaaaaaaaaaaaaaaaaaaaaa....]

eventually, other symbols appear on "imagem" field. suppose right, i'm not

sure.

on android app, have routine download image , store blob in database. receive json format , transform class jackson. i've logged "imagem" field , looks same.

my problem can't transform image. here's code snippet:

byte[] img_bandeira = cursor.getblob(cursor.getcolumnindex("img_bandeira"));         bitmap bmpbandeira = bitmapfactory.decodebytearray(img_bandeira, 0, img_bandeira.length);         imageview ivbandeira = (imageview) view.findviewbyid(r.id.ivbandeira);         ivbandeira.setimagebitmap(bmpbandeira); 

all message: skimagedecoder::factory returned null.

i've looked @ other similar posts, tried change lines, nothing happened. don't know what's going on here. in advance.

i solved it. in server, image should sent this:

bytearrayoutputstream baos = new bytearrayoutputstream();                 bufferedimage img = imageio.read(new file(caminho.replace("/", "//")));                 imageio.write(img, "png", baos);                 baos.flush();                 string base64string = base64.encode(baos.tobytearray());                 baos.close(); 

in app, should read this:

public static bitmap getimage(byte[] imagearray) {         bytearrayinputstream bytearrayinputstream = new bytearrayinputstream(imagearray);         bitmap bitmap = bitmapfactory.decodestream(bytearrayinputstream);         return bitmap;     } 

thank you, ;)
