instagram-clone-kotlin's Issues

Display data loading/request processing progress

Add DI

Common issues

• Forgetting to pass ViewModelFactory to ViewModelProvider
• Forgetting to add failure listener for a task(and show toast)

Notification tooltip slight hiccup

Proper testable Model layer

Q

Testable view models

1. Move firebase code from view models.
2. Move logic from activity inside view models.

Loading indicator

Single onFailureListener for all activities

Reduce starting Activity boilerplate

An Activity may be started from different places. And it may need some required parameters.

It's better to have a single typesafe method that starts activity and thus will warn me at compile time if I forgot to add some parameter.

ServerValue.Timestamp causes 2 changes from realtime database

Find out why and what can be done to avoid this.

Google Play preparation

Plural form for stats

Reduce duplication and delegation boilerplate

Any change requires changing signatures in all three places: Activity, ViewModel, Presenter(currently domain class)

Add Data Binding

Block landscape mode

Remove feed image blinking on like

Search feature

Static assets

Firebase

How to setup firebase sir?
Can you explain me :) ?

Better icons for notifications

Single viewModel builder

It will help to not forget to pass our ViewModelFactory.

Categorize extension functions into domain-specific files

Disable animation on comments activity

It is unnecessary and breaks notifications tooltip when going from comments to feed.

Sign-Up Error Message

Hello,

I followed the steps to add the app to firebase, and I installed it on my phone. I also enabled email/password authentication in firebase.

When I try to sign up, the app complains that the email used for registration is already registered. However, when I quit the app and start it again, I see that I can sign in i.e. the registration is successful in spite of getting the error message.

Any thoughts?

Thanks.

Is there any Demo App

Is there any demo apk available to see the demo.

ProGuard

String resources

Wrong image crop in feed

Weird crop of image in the feed after going back from comments activity.
It also happens on post like.

Use subset of User object in UserProfileActivity

Currently User object is passed to update user profile.
But not all fields are used in profile. I should create a Profile class with subset of fields.

Paging library

Extract Firebase access into separate layer

I certainly need to keep some persistence logic in a single place without duplication.

It should help avoid duplication and at the same time keep things simple.

So I think it's gonna be a simple domain layer with both logic and Firebase access code in it.

It could be written in two layers like Presenter + Repository, but we don't need a separate repository layer, since Firebase already manages offline mode and caching for us really well.

Repository layer

Updates all references on user profile update

Does it actually appear like displayed in pics??
