I am working on uploading a picture to a server. I am able to successfully upload an image using iOS but when i try on android I get the error code 3. Currently using phoneg
This could also be a reason, and solved it for me:
iOS 9 and OSX 10.11 require TLSv1.2 SSL for all hosts you plan to request data from unless you specify exception domains in your app's Info.plist file.
