In Android development, encapsulating a website typically refers to creating an interface that allows you to interact with the website's content without exposing its underlying implementation details or hosting the entire site within your app. This is often done using webviews and APIs. Here's a basic explanation: 1. **WebView**: WebView is a built-in component that lets you display HTML, CSS, and JavaScript content inside an Android app. You can load websites by setting the WebView's `loadUrl()` method with the desired URL. ```java WebView webView = findViewById(R.id.web_view); webView.loadUrl("https://example.com"); ``` 2. **Content Providers (optional)**: If you need to access specific data from the website, you might consider using a Content Provider to fetch that information. For instance, if the website offers JSON data, you can create a custom content provider for your app to consume. 3. **API Integration**: If the website has an API, use Android's HTTP clients like `HttpClient` or later `OkHttp`, or even better, with Retrofit for a more structured approach. This allows you to make calls to the server programmatically. 4. **Separation of Concerns**: To maintain encapsulation, separate the code responsible for interacting with the website (the "adapter" layer) from your app's core logic. This helps keep your app clean and maintainable. ```java // Using Retrofit for API integration Retrofit retrofit = new Retrofit.Builder() .baseUrl("https://api.example.com/") .addConverterFactory(GsonConverterFactory.create()) .build(); ApiService service = retrofit.create(ApiService.class); Call<ApiResponse> call = service.getData(); call.enqueue(new Callback<ApiResponse>() { @Override public void onResponse(Call<ApiResponse> call, Response<ApiResponse> response) { // Handle API response } @Override public void onFailure(Call<ApiResponse> call, Throwable t) { // Handle errors } }); ``` **
