Implementing Dynamic Status Bar Color Changes

We’ll use JavaScript to communicate with the Android WebView and change the status bar color dynamically. Follow these steps:

1. **Enable JavaScript in Your WebView:**

Make sure JavaScript is enabled in your WebView by modifying the `MainActivity.java` file:

“`java
WebView webView = findViewById(R.id.webview);
webView.getSettings().setJavaScriptEnabled(true);
webView.addJavascriptInterface(new WebAppInterface(this), Android);
“`

2. **Create a JavaScript Interface:**

Add the following interface to your `MainActivity.java`:

“`java
public class WebAppInterface {
Context mContext;

WebAppInterface(Context c) {
mContext = c;
}

@JavascriptInterface
public void changeStatusBarColor(String color) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
getWindow().setStatusBarColor(Color.parseColor(color));
}
}
}
“`

3. **Call the Interface from JavaScript:**

Include JavaScript code on your website to call this interface. Here’s an example script you can include in your
