我要开始在Android中,检查哪一个应用程序在后台不断运行的服务。如果前台应用程序在我的应用程序的数据库中,那么它会打开一个密码屏幕来输入密码。开始不断运行服务
我已经取得了什么是我的服务,只要在应用程序运行,但是当我停止应用程序(从以前的应用程序中删除),那么我的服务停止运行。无需输入密码即可打开锁定的应用程序。我在互联网上尝试了很多解决方案,但似乎没有任何工作。请帮我,

我可以提供AppChecker类的代码,如果你想要的。请让我知道我应该怎么做才能达到预期的效果。我会非常感激你。
您是否尝试过在服务的OnCreate移动你的代码,因为当服务重新创建,它总是调用ONC reate –
你在测试什么设备? –
嗨,谢谢大卫对你的回应。我正在使用运行android 5.1的HUAWEI TAG-L21进行测试。当应用程序从最近的应用程序中移除时,该服务停止。 –
