判断一个应用是否在前台代码库有问题？ #16

public static boolean isAppForegroundRunning(final Context context) {
	ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
    if (activityManager == null) return false;
    List<ActivityManager.RunningTaskInfo> tasks = activityManager.getRunningTasks(1);
    if (!tasks.isEmpty()) {
        ComponentName topActivity = tasks.get(0).topActivity;
        if (topActivity.getPackageName().equals(context.getPackageName())) {
            return true;
        }
    }
    return false;
}
