Android programming method to determine whether the currently specified app is in the foreground

This article describes the method of Android programming to determine whether the currently specified app is in the foreground. Share it for your reference, as follows:

//Search for the current APP information in the process to determine whether it is running in the foregroundprivate boolean isAppOnForeground() {
ActivityManager activityManager =(ActivityManager) getApplicationContext().getSystemService(
  Context.ACTIVITY_SERVICE);
String packageName =getApplicationContext().getPackageName();
List&lt;RunningAppProcessInfo&gt;appProcesses = ();
if (appProcesses == null)
return false;
for (RunningAppProcessInfo appProcess : appProcesses) {
if ((packageName)
    &amp;&amp;  == RunningAppProcessInfo.IMPORTANCE_FOREGROUND) {
  return true;
}
}
return false;
}

I hope this article will be helpful to everyone's Android programming design.
