【中文标题】带有 Google Play 服务位置的 Android 服务导致应用程序随机打开【英文标题】：Android Service With Google Play Services Location Causing App to Open Randomly 【发布时间】：2017-04-17 23:25:51 【问题描述】：我有一项服务应该捕获用户的位置和当前电池电量并将其发送到我的 Firebase 后端。出于某种原因，似乎每当我在我的应用程序中启用此服务时，我的应用程序都会在没有任何用户交互的情况下随机打开（即使用户在另一个应用程序中，我的应用程序也会弹出打开）。有谁知道为什么会这样？
这是我的服务代码：

【问题讨论】：
您是否使用自定义的 Application 类，如果是，您能否为 Application 类添加源代码？能否请您添加一个完整的清单文件？ 我现在添加了这些附加信息 您正在从您的应用程序启动一个活动：这会导致您的应用程序弹出。将与要启动的活动（MainActivity 或 Intro）相关的逻辑放在 Activity 中，并将其配置为 LAUNCHER 活动（基本上复制您在 MainActivity 清单文件中已经完成的操作） 【参考方案1】：嗯，不能保证系统一直运行您的服务。当应用程序被终止并且必须交付新位置时，播放服务库将实例化应用程序并启动您的服务。您必须从应用程序类中删除 startActivity。
【讨论】：
这是正确的。切勿将 Application 中的 startActivity() 作为常规启动例程的一部分。相反，使用没有屏幕的活动作为启动器。查看gist.github.com/chanakin/c44bf1c6a9a80d2640440b5aaa92c8ee 示例代码。以上是关于带有 Google Play 服务位置的 Android 服务导致应用程序随机打开的主要内容，如果未能解决你的问题，请参考以下文章
