bitcoin-market-android's Issues

Click on BackPress Button in MarketScreen

When I click on the backpress button in MarketScreen, I see SplashScreen again. It should exit from the application.

Move to Jetpack Compose

Implement Jetpack Compose and make the UI composable

Need to Be Upgrade Room version to 2.4.2

RoomDb version should be upgraded. With current version "2.3.0" it can not compile on M1 MacBooks
following exception occurred on m1 Macs Caused by: java.lang.Exception: No native library is found for os.name=Mac and os.arch=aarch64.

current room version : 2.3.0
expected room version: 2.4.2

Add SwipeToRefresh to MarketScreen

Dark theme 🌑

I can make the darktheme🌚

Double Splash Screen

First the default splash screen (https://developer.android.com/guide/topics/ui/splash-screen) plays and then the additional one implemented in the app. Is this intentional? It seems a bit weird. I think it would be an improvement if the default one was disabled.

Move to Jetpack Compose Navigation

Remove MPChart

Replace the mpchart with compose

Improvement for caching

• Remove the shared preferences and keep the expired information in the entity
• Return the data always from the database

Chart prices don't seem on the dark theme.

A small bug came with dark theme support. Currently, chart prices don't seem on the dark theme.

Send Daily Notifications of The Current Price

As a User,
I want to get a notification of the current price at 12:00 every day,
so that I can track the price easily

Add a code analysis tool

I think it would be nice to have a code analysis tool to keep the syntax. Detekt is a nice solution but of course, I'm open to discussing your idea.

Add wearOS support

Show loader Instead of showing an full screen component

I'm not sure Is there any particular reason to show a full screen while pulling to refresh or fetching data from API ?

I guess user experience can be improved by showing a dialog instead of showing whole full screen composable

Create Cache Mechanism

As an improvement point, we can add a memory cache mechanism to the project. Return the data from the memory if it is not expired. The expiry time can be one minute.

Create a widget

https://developer.android.com/guide/topics/appwidgets/overview

adding support for android 12

File structure

Hi, it is my first time working on open source
so i am going to change the file structure and move the core to new module

show list of crypto

I think it will be a good idea to add recyclerview inside a fragment to show multiple currencies, in this case we will cover multiple android topics, we can also cache them with room

enable proguard rules

Infinity loop for LoadingAnimation

Migrate to multi-module

Add a test coverage tool

Create a GitHub Action

Create a Github Action and run unit tests and build the project

Write UI test for compose

https://developer.android.com/jetpack/compose/testing

Write unit test for the ViewModel
