我曾尝试每一个建议，我可以在网上找到使用前台服务，以保持我的应用程序运行超出了睡眠和深度睡眠模式，但没有已经成功至今的。
我工作的一个出租车预订应用程序。 我设计的开始发射的驾驶位置服务器每当驾驶员打开自己的在线和停止时发出脱机。
以下是每当驾驶员打开自己的在线时启动，当他按下按钮，在线从而改变Common.CustomSocketOn 0停止前景服务代码。
它的屏幕唤醒期间正常工作，也当屏幕关闭的应用程序就会被杀死之前的作品。
然而，即使有WAKE_LOCK收购，但仍无法通过Android的7被杀前停留超过几分钟的睡眠模式。
因为当应用程序被打死默默地，它不会打开驱动器离线也不帮他签的机会，这未能保持在睡眠模式下运行打破了应用程序的许多其他功能。 其结果是，司机被预订请求时，他的应用程序没有运行，因此，也顾不上它，而保持从去到下一个可用的驱动器的预订。 事实上，这会导致许多其他异常。
请，有人可以告诉我，我需要做的，让Android的杀死了前台服务任何其他东西。
