Checking App Execution Status on Android

As an Android developer, you may often encounter the need to check if a specific app, such as the default browser, is running. This functionality is essential for implementing conditional behaviors or interactions within your application.

To accomplish this programmatically, a straightforward approach involves utilizing the ActivityManager class. The following code snippet provides an example of how to detect if the default browser is currently running:

import android.app.ActivityManager;
import android.content.Context;

public class BrowserCheck {

    public static boolean isBrowserRunning(Context context) {
        ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
        List processes = activityManager.getRunningAppProcesses();

        for (ActivityManager.RunningAppProcessInfo process : processes) {
            if (process.processName.equals("com.android.browser")) {
                return true;
            }
        }

        return false;
    }
}

In this code, we first obtain an instance of the ActivityManager service and retrieve a list of running app processes. We then iterate through this list to check if any process matches the package name of the default browser (com.android.browser). If a matching process is found, we confirm that the browser is currently running.

You can integrate this code into your application's logic to conditionally perform actions or display messages based on the browser's running status.
