Chat app for gitter

chatter's Issues

No messages being displayed in the rooms

Current the messages are not being displayed in a room.
Also the networking is handled poorly, multiple API calls are made.

Adding Rxjava for Api calls

Use of Rx java and retrofit for API calls and checking networking connectivity in realtime using Rx java

Blank Activity / Fragment on every tab

Clicking on any tab shows a blank activity / fragment

add issue template for github

There should be an issue template added to the repo for enabling a proper documentation of bugs and updations to the code-base

Enhance Dashboard Activity

Populating the Dashboard Activity would be the next step to go forward.

• Store user data received from Gitter API, by making a call with access token to the API in shared Preferences.
• Implement Realm db
• If on the first use the user is offine it will redirect to NoNetwork Activity
• Get rooms data and store them in Realm db.
• Implement Recycler View in Dashboard Activity listing out the rooms and users with number of unread messages and sorted by last taken room time stamp from the Realm db.
• On clicking a room or user should open a dedicated Activity. [Currently blank].

Difficulty: Hard

RoomFragment

RoomFragment is getting empty object

Add display message support for rooms

Since, we got a rooms fragment which displays all our rooms, we now would need to view messages from them.

• Add onClick attribute to the dynamically generated views which opens a new fragment.
• Pass the room id to the other fragment.
• If network is available try to get new messages and populate the realm table for messages.
• If network is not available and no messages are there in the realm db, redirect to network connection page.
• If no messages are in the room even after there is an internet connection, show it to the user.
• Get the messages from the realm db sorting it with id of the row.
• Display the messages in a recycler view.

Difficulty: Hard

Fix API changes

Issues-

1. There are many crashes after building the project. Make appropriate changes to revive the app.
2. Set targetSdk to 27 for latest os and use latest build tools available.

I'm working on this

Show the Room Message with proper layout and display according to the Date

Actual Behaviour

At present, the Room message show without any order means recent message display on top of recycler view and room message has not a proper layout and there is no any mechanism to detect the link in the message.

Expected Behaviour
Room Message must be displayed according to the date and in user message the web link automatically recognize

Steps to reproduce it
Adding the business logic and make a good layout.

LogCat for the issue

No Logcat this is only improvement

Screenshots of the issue

You can see that message are not in proper order which means recent message should be displayed at last.

Expected Bounty

Null Pointer Exception in RoomFragment class

Actual Behaviour: The RoomFragment class produce Null pointer exception upon frequent clicking on several lobbies together.

Cause: The fragments get detached from their concerned activity upon frequent traversal, so the call to getActivity() method results in Null pointer exception.

Would you like to work on this issue: Yes.

Design an icon for the app

An app icon would be awesome.

CC: @championswimmer @the-dagger

Update build dependencies to latest gradle/studio versions

Do not work on this before #80

Use Architecture Components

Since the current size of the project is small and the app idea has good potential. Only authentication works perfectly right now. It would be great to start using the Architecture components now to increase maintainability, readability and developing experience. Also, follow Repository pattern.
This transformation should be done over multiple pull request step-by-step.

• Add Room and LiveData library and make the required model class, dao class, and database. Do not hook it into UI yet.
• Separate all networking call in one class to support Repository pattern
• Create a single class DataRepository to work in sync with local database and network
• Create ViewModel classes of activities and fragments.
• Now call methods from ViewModels in activities and fragments to populate the UI (Use databinding to get rid of more boilerplate code).
  Iterate as per new feature added

@championswimmer @the-dagger Need your suggestions.

ButterKnife binding

ButterKnife.bind(this); in the AuthenticationActivity.java should be written after setcontentview

Bad implementation of Splash screen

Actual Behaviour
Currently, the splash screen loads full-fledged layout which takes a noticeable amount of time to load

Expected Behaviour
Splash screen should not have layout but themes. Themes loads almost instantly.

Steps to reproduce it

1. Open the app.

Add support for sending messages and drafts

The following steps would need to be taken:

• Implement input TextBox along side the RecyclerView which currently takes the complete height of the parent.
• Implement sending the message when internet is available with the help of Gitter API
• Add a new column called DraftMessage in the RoomsTable which will give us drafted message support.
• Modify the MessagesTable and add another column called syncState which denotes the whether the message has been synced or not. (This is extremely usefull when internet is not available)
• Implement SyncAdapter to sync not synced items in MessagesTable to be synced with Gitter.
• Implement broadcast recievers, stub content provider and services to support the SyncAdapter
• Make sure the message is sent as sync adapter fails in certain circumstances.

Difficulty: Hard

Showing the organization image of each item in Recylerview

I think it is necessary to show the organization image in recyclerview at each item in rooms fragment. It will enhance the user experience to show the organization image in cardview. Right now the only text is showing.

Swipe to refresh the RoomsFragment Layout

Actual Behaviour

Now there is no any option to refresh the RoomsFragment to know the unread message in RoomsFragment. We only have one option which is click the Room button in bottom navigation

Expected Behaviour

I think it is the good choice to refresh the RoomsFragment when we vertical swipe in the screen.

Steps to reproduce it

Adding theSwipeRefreshLayout in the RoomsFragment layout.

Error 404 on gitterAPI call

At first after adding logs to all requests, I found that the server is not giving any response (404 not found) due to which the JSONObject Class is unable to create a json object

• The shared preferences are successfully saving the user's access token
• the okhttp request

Request request = new Request.Builder()
                        .url("https://gitter.im/v1/user/me")
                        .addHeader("Accept", "application/json")
                        .addHeader("Authorization:", "Bearer " + accessToken)
                        .build();

is giving no response(404)

• thus the JSONObject is not created.

Add notifications support

• Implement TaskStackBuilder builder object
• Sync messages when you are connected online by extending the capabilities of the already
  implemented SyncAdapter in #10 via #13
• Add extending capacities so that messages can be viewed channel wise inside the notification shade via the NotificationCompat.Builder
• Create a PendingIntent for the Activity. Call setContentIntent() to add the PendingIntent to the notification and route the user the dashboard.
• Add support for updating notifications.
• Add support for removing notifications

Add gitter api based authentication to the app

• Take out the current chat activity as it is a boiler plate only.
• Create a new Gitter app in order to make use of the gitter api
• Implement authentication as mentioned in a complex process by the Gitter API at: https://developer.gitter.im/docs/authentication
• For the last phase a networking client can be used as the stock way sucks like OkHttp
• Store the generated access code in shared preference and display it in dashboard activity.
• When no access_code is there make the user to authenticate again and if internet is also absent in addition prompt the user to authenticate.
• Add Butterknife

The steps are complex and would need the use of a Web browser thus recommending to use a WebView and a dedicated activity for authentication.

Complexity: Hard.

Currently all the code-files are in a single directory. Organizing it into directories for Fragments, Adapters etc. would be easy for viewing purposes.

App crash upon traversing through all the buttons in the bottom nav bar

When the user first selects the Rooms tab, it works fine. (I am working on the issue #26 ) . But after frequent and continuous traversal of all the tabs, the app crashes.
