即使关闭Activity，也要保持Android服务运行 [英] Keep Android service running even after Activity is closed
问题描述
我正在构建其中的SOS应用程序之一。每当设备震动超过阈值（通过加速度计检测到）时，我都会显示 Toast （截至目前）
I am building one of those SOS apps. Whenever the device is shaken above a threshold value (detected through accelerometer), I am showing a Toast (as of now)
1）应用启动。用户提供姓名，电子邮件等。然后在最后一个屏幕上单击完成。
1) App is launched. User gives name, email, etc.. and clicks finish on last screen.
2）服务已启动，不断监听震动。
2) Service is started which keeps listening for shake.
3）如果应用程序正在运行，它将正确检测到震动。
3) It detects the shake correctly if the App is running.
4）如果我关闭该应用程序（活动），该服务将随之消失。
4) If I close the app (the activity), the service gets killed along with it.
即使应用已关闭，如何保持服务仍在运行，以便它可以听到来自背景的震动？ （这就是该应用程序的全部目的）
How do I keep the service running even if app is closed, so that it can listen to shakes from background? (That's the whole purpose of this app)

推荐答案
您有两个选择：
- 将服务作为前台服务启动（使用
startForeground（int id，Notification notification）：文档。但是在这种情况下，只要您的服务正在运行，您就必须在通知栏中显示通知。 - 为服务使用单独的进程，将清单添加到您的进程中
android：process =：nameofyourprocess
- Start your service as foreground service (with
startForeground(int id, Notification notification): docs. But in this case you will have to show Notification in notification tray for as long as your service is running - Use separate process for your service adding in manifest to your process
android:process=":nameofyourprocess"
