Android - Send Image file to the Server DB -
users save 3 data: name, note , image. can see code below, succeeded code send name , note server side. but, have no idea how send selected image file device serverdb.

you can convert selected image base 64 string , pass string server , in server decode that,
check code convert image base64,if have imageview can write code,
imageview.builddrawingcache(); bitmap bm = imageview.getdrawingcache(); bytearrayoutputstream baos = new bytearrayoutputstream(); bm.compress(bitmap.compressformat.jpeg, 100, baos); //bm bitmap object byte[] b = baos.tobytearray(); string encodedimage = base64.encodetostring(b , base64.default); edit
as in code,you have byte array in line,
image = extras.getbytearray("blob"); so can directly write line of code after that,
string encodedimage = base64.encodetostring(image , base64.default);
