+# News App
+
+This is a News App developed using Kotlin and XML. The app fetches news articles from a news API, displays them in a user-friendly interface, and includes a search functionality to find specific news articles.
+
+---
+
+## Features
+
+- **Fetch Latest News**: Retrieves news articles from a reliable API.
+- **Search News**: Search for articles by keywords.
+- **User-Friendly Interface**: Designed using XML for a clean and intuitive UI.
+- **Kotlin-Based**: Fully written in Kotlin for robust and modern development.
+
+---
+
+## Prerequisites
+
+Before running the app, ensure you have the following:
+
+- Android Studio installed on your system.
+- A valid API key from the news API provider.
+- Minimum SDK version: 21 (Android 5.0, Lollipop).
+- Internet access for fetching news articles.
+
+---
+
+## API Details
+
+The app uses a third-party news API to fetch the latest news articles.
+
+1. **API Endpoint**: Replace `{API_KEY}` with your actual API key.
+
+   ```plaintext
+   https://newsapi.org/v2/everything?q={query}&apiKey={API_KEY}
+   ```
+
+2. **Required Parameters**:
+
+   - `q`: Search keyword (string).
+   - `apiKey`: Your API key (string).
+
+3. **Response**:
+   The API returns a JSON response with fields such as `title`, `description`, `urlToImage`, and `publishedAt`.
+

+
+## ER Diagram
+
+Below is the Entity-Relationship (ER) diagram representing the News App:
+
+### Diagram Representation
+
+- **Entities**:
+  - **Users**: Represents the app users.
+  - **News Articles**: Represents the fetched news articles.
+  - **API**: Represents the news API used to fetch articles.
+
+- **Relationships**:
+  - **Users** can search for and read **News Articles**.
+  - **News Articles** are fetched from the **API**.
+
+```
+[Users] --- Searches ---> [News Articles]
+[Users] --- Reads ---> [News Articles]
+[API] --- Fetches ---> [News Articles]
+```
+
+### How It Works
+1. **User Interaction**: Users interact with the app through a search bar and list of news articles.
+2. **API Request**: When a search query is entered, the app sends a request to the News API.
+3. **Data Fetching**: The API fetches relevant articles based on the query.
+4. **Display Articles**: The fetched news articles are displayed in a recycler view for users to read.
+5. **Continuous Interaction**: Users can perform multiple searches and view details of articles.

+## Installation
+
+1. Clone the repository:
+
+   ```bash
+   git clone https://github.com/your-username/news-app.git
+   ```
+
+2. Open the project in Android Studio.
+
+3. Add your API key in `Constants.kt`:
+
+   ```kotlin
+   object Constants {
+       const val BASE_URL = "https://newsapi.org/v2/"
+       const val API_KEY = "your_api_key_here"
+   }
+   ```
+
+4. Build and run the app on an emulator or physical device.

+
+#### Fetching News
+
+```kotlin
+private fun fetchNews(query: String) {
+    val newsApi = NewsService.create().getNews(query, Constants.API_KEY)
+
+    newsApi.enqueue(object : Callback<NewsResponse> {
+        override fun onResponse(call: Call<NewsResponse>, response: Response<NewsResponse>) {
+            if (response.isSuccessful) {
+                val newsList = response.body()?.articles ?: emptyList()
+                newsRecyclerView.adapter = NewsAdapter(newsList)
+            }
+        }
+
+        override fun onFailure(call: Call<NewsResponse>, t: Throwable) {
+            // Handle failure
+        }
+    })
+}
+```
+
+#### Retrofit Service
+
+```kotlin
