How can I check if an app running on Android?

Add the below Helper class:

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

Now you can check from the below code if your desired App is running or not:

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

isInBackground is the status of app

ActivityManager.RunningAppProcessInfo myProcess = new ActivityManager.RunningAppProcessInfo();ActivityManager.getMyMemoryState(myProcess);Boolean isInBackground = myProcess.importance != ActivityManager.RunningAppProcessInfo.IMPORTANCE_FOREGROUND;

You can check it by the following method

public static boolean isRunning(Context ctx) {    ActivityManager activityManager = (ActivityManager) ctx.getSystemService(Context.ACTIVITY_SERVICE);    List<ActivityManager.RunningTaskInfo> tasks = activityManager.getRunningTasks(Integer.MAX_VALUE);    for (ActivityManager.RunningTaskInfo task : tasks) {        if (ctx.getPackageName().equalsIgnoreCase(task.baseActivity.getPackageName()))            return true;    }    return false;}
