I successfully created an .apk file using the "Build"

I successfully signed and installed it on a Galaxy Smartphone.

The following issues exist and there is nothing within my means that could correct them:

1.  Although I can upload a text "Article" with the app, I can NOT upload an image. The app indicates "Please wait while your data is uploaded!"  but it never uploads.  Once again, I can upload text messages, I just can't upload the "Intro Image."

2.  I cannot "Submit" the "Contact Us" message, the Submit link does not work.

3. No "Notifications" work at all.

I rebuilt the app several times but I always get the exact same issue listed above.  There is nothing I can possibly do at my end. All information has been entered correctly and the app functions except for the above issues at this time.
