Getting an error in :
if (status.equals(Constant.REQUEST_SUCCESS))
Error : Cannot resolve symbol

Do I need to create a "Constant" class?

replace "Constant.REQUEST_SUCCESS" that with the success message returned by your server

Bro, you're an actual lifesaver, I've looked everywhere for this, Such a clean and well-commented solution, you're amazing

Hey, thank you so much.
Just a minor correction:

at MainActivity.java, line 98
replace "mAvatarInput" with "mAboutInput"

"dataOutputStream.write(parameterValue.getBytes("utf-8"));"
"dataOutputStream.writeBytes(lineEnd);"

Thanks for the answer you saved my life...
