Resolving Date Format Conversion Issues in Java for Your Android App

Handling date and time is a common requirement in Android app development. However, many developers face challenges when converting date formats, especially when fetching data from APIs. If you're seeing blank data for date fields in your app, you're not alone. This guide dives into the problem of date format conversion in Java and provides a step-by-step solution to ensure your app displays the correct date and time.

The Problem

When you receive a date and time string from an API response, such as:

you need to convert this string into a format suitable for display in your Android app. Many developers encounter issues where, despite writing what seems like the correct code, the date displayed is blank. This usually stems from improper date parsing or format settings.

Example Code Snippet

Here is a simplified version of the code that's often used for parsing dates and displaying them in a TextView:

Why Your Original Code Might Not Work

The issue with the original code lies in how the date string from the API is being parsed and formatted. If you're using SimpleDateFormat, it expects a Date object but might not properly handle the incoming date string format or timezone.

The Solution: Updated Code for Date Parsing

Step-by-Step Solution

Import Necessary Classes: Make sure to import the LocalDateTime, Instant, and DateTimeFormatter classes.
