android - How to convert Bitmap to Base64 String -

i developing android application uploads base64 string of image web server. therefore, have used following code convert bitmap base64 string.

public string getencoded64imagestringfrombitmap(bitmap bitmap) {     bytearrayoutputstream stream = new bytearrayoutputstream();     bitmap.compress(bitmap.compressformat.png, 100, stream);     byte[] byteformat = stream.tobytearray();     string imgstring = base64.encodetostring(byteformat, base64.no_wrap);     return imgstring; } 

for example, need convert image. after conversion, i'm not getting base64 string expected.
