Exmaple -
Case of no data for a particular SOL : https://api.nasa.gov/mars-photos/api/v1/rovers/Spirit/photos?sol=2202&api_key=pnfYfjK3FhG77VCRO2ZwtjI4w9hq0fXRozkZ0VbY

Currently, the user has to go back to the image grid section from the expanded image activity to select a new image. For a better UX, the user should be able to swipe left/right and move on to the next/previous image respectively.

A simple toggle on the home screen that can enable user to select temperature unit preference. The preference becomes the default unit for that user.

Line graph to show the frequency of images being taken.

Create an 'About' page that'll show usual 'About' information.

Research into the most appropriate analytics tool for the app and implement on the decided tool.

Ability for the user to zoom into expanded images.

1. Shared element transition occasionally gets stuck when navigating from Main Activity to Explore Activity. This is observed specially when user taps on a rover button navigates to Explore activity, returns and then taps on another rover button.
2. The transition is not smooth on navigating from explore fragment to expanded view and on navigating back.

1. A general information page for every rover.
2. Maybe make a backend to update the information via an API.

1. Expand image on tap.
2. Give zoom in capabilities.
3. Save/ Download option.
4. Show available details of the image (eg. Camera)

Each card (Weather report, rover buttons) slides up individually on 'onCreate' of the home activity.

2. Release labels - https://github.com/krtkush/MarsExplorer/releases

1. Loading animation on first load.
2. Illustration on no data.
3. Illustration on network fail.

Check Leak Canary reports.

Keep track of all TODOs in Android Studio.

Changes to be made to the grid layout -

1. Image details partially overlapping their respective images - Done.
2. Spacing around the columns - Done.
3. Loading animation on pagination - Done.
4. Make collapsible toolbar smoother on expansion and contraction - Seems to be smooth.
5. Grid items scroll up animation - Done.
6. Pull down to refresh - Done.

User should be able to directly navigate to a specific SOL (maybe even date) via an input option.

The API has been changed and pagination has been removed.
