Android Question

check android application is in foreground or not?

I went through a lot of answers for this question.But it's all about single activity..How to check whether the whole app is running in foreground or not ?

Answer Source

I don't understand what you want, but You can detect currently foreground/background application with ActivityManager.getRunningAppProcesses() call.

Something like,

class ForegroundCheckTask extends AsyncTask<Context, Void, Boolean> {

  protected Boolean doInBackground(Context... params) {
    final Context context = params[0].getApplicationContext();
    return isAppOnForeground(context);

  private boolean isAppOnForeground(Context context) {
    ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
    List<RunningAppProcessInfo> appProcesses = activityManager.getRunningAppProcesses();
    if (appProcesses == null) {
      return false;
    final String packageName = context.getPackageName();
    for (RunningAppProcessInfo appProcess : appProcesses) {
      if (appProcess.importance == RunningAppProcessInfo.IMPORTANCE_FOREGROUND && appProcess.processName.equals(packageName)) {
        return true;
    return false;

// Use like this:
boolean foregroud = new ForegroundCheckTask().execute(context).get();

Also let me know if I misunderstand..
