you need convert image-view base64 string below.

1]convert imageview bitmap.

  imageview.builddrawingcache();   bitmap bmap = imageview.getdrawingcache(); 

2]bitmap base64 string.

public string getencoded64imagestringfrombitmap(bitmap bitmap) {       bytearrayoutputstream stream = new bytearrayoutputstream();       bitmap.compress(compressformat.jpeg, 70, stream);       byte[] byteformat = stream.tobytearray();       // base 64 string       string imgstring = base64.encodetostring(byteformat, base64.no_wrap);   return imgstring; } 

3]base64 bitmap.

byte[] decodedstring = base64.decode(base64string.getbytes(), base64.default); bitmap decodedbyte = bitmapfactory.decodebytearray(decodedstring, 0, decodedstring.length); 

set bitmap imageview.
