How to Programmatically Check if the Default Browser is Running on an Android Device?

Detecting App Execution on Android Devices

Ensuring the activation status of an app is fundamental for various programming scenarios. Android developers often encounter the need to verify if the default browser is in operation. To address this requirement, this article introduces a comprehensive solution.

Checking Browser Execution in Android

To programmatically check whether the default browser is running on an Android device, you can leverage the following Helper class:

public class Helper {
    public static boolean isAppRunning(final Context context, final String packageName) {
        ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
        List<ActivityManager.RunningAppProcessInfo> procInfos = activityManager.getRunningAppProcesses();
        if (procInfos != null) {
            for (ActivityManager.RunningAppProcessInfo processInfo: procInfos) {
                if (processInfo.processName.equals(packageName)) {
                    return true;
                }
            }
        }
        return false;
    }
}

Utilizing the Helper Class

With the Helper class defined, you can conveniently check if a specific app is running. For instance, to check if the default browser is active:

if (Helper.isAppRunning(YourActivity.this, "com.your.desired.app")) {
    // App is running
} else {
    // App is not running
}

By incorporating this approach, Android developers can reliably detect the running status of the default browser or any other desired application. This knowledge proves beneficial in a multitude of programmatic scenarios, enabling developers to enhance the functionality and user experience of their Android applications.
