Android Fitbit-like App for fetching user information

fitbitapp's Issues

Invalid scope when login

this is because the requested HTTP_URL has invalid values, in this example, it's "setting" instead of the correct "settings".

Another one is that I should the concatenated string using "+", not the ","

This is fixed by the getPermissionAsString() functions.

FileNotFound: when access token using the formated url

Use third-party libs, but face some issues when implementing in our fitbit apps:

• GetAccessToken::doInbackground(), this functioin's param[0] is url, but it appends an null at the end
• Even I use correct url above, I still cannot pass through the function, error is FileNotFound when using urlConnect

And the libs is a little behind the code, some codes are override, and some tasks are hidden but called, use debugging tools is good for tracking, but the solution still needs for researching. Something about the HTTP request...

See the note that I marked as the correct one, but still failed.

Webview issue when destroying

There is some issue when destroy the webview after log in, as we need to close this view, the error is shown as below:

Error: WebView.destroy() called while still attached!

Some guidance about the code

NOTE

This document serves as the guidance of the code, which will help us greatly understand the code well. I read the code, as well as using android studio debugging to track its process. Some process are hidden and it's not easy to track.

Just marking for future reference

Overview

Three basic modules:

• EasySocial: basic module, some POST/GET operation related with facebook(NEED enhancement)
• EasySocialFacebook: facebook implementation(third-party example)
• MyFitBitModule: our implementation, bug fixs, adjusted version for fitbit.
• App: Entry for the main activity/application

Process

when click login
MainFragment -> Fitbit.login -> EasySocialAuthActivity creating -> GetAccessToken
(parseToken etc...)

Token
EasyWebViewClient -> GetAccessToken ->

Fetch information
EasySocialFitbit -> GetUserInfo -> GetAccessToken -> "POST/GET packets"

NullPointerException: When request the activity information using Json Libs

When request some activity information like calorie, it seems that the callback function has null parameter, which cause the code crashing, as follows:

The code snippets are located here:(but should be caused anywhere else)

    public void getUserInfo(Context context, final UserInfoCallback userInfoCallback){

        GetWebRequest getWebRequest = new GetWebRequest(new WebRequest.Callback() {
