Android Oreo上的永久服务 [英] Permanent services on android oreo

问题描述

Android 8的电池消耗改进对用户来说不错，但我有点担心我的服务能否按预期工作.

Android 8's battery consumption improvements are nice to the user but I am a bit afraid if my service will work as expected.

首先:谢谢您的任何建议，但我不能只安排我的服务.我想制作一个一直在后台运行的类似OK Google的关键字侦听器.它将基于开源的Pocketsphinx-android库.我知道这会消耗很多电池电量，因此我会通知用户.

First of all: Thank you for any suggestions but I cannot just schedule my service. I want to make a OK Google-like keyword listener running in the background all the time. It will be based on the open source pocketsphinx-android library. I know that this will consume much battery power and I will inform the user about this.

我们可以在android 8+上创建永久后台服务吗?我需要在gradle中定位android 8，因为我期望使用较旧的目标会出现一些错误.我也不想让前台服务永久性地在状态栏中显示通知的用户烦恼.

Can we create a permanent background service on android 8+ ? I need to target android 8 in gradle because I was expecting some bugs with older targets. I also don't want to annoy a user with a foreground service which permanently shows a notification in the status bar.

[ https://developer.android.com/about/versions /oreo/background.html] -真的没有办法为我的用例(但最好是所有用例)提供永久的后台服务吗?

推荐答案

不幸的是，在Android 8.0及更高版本上，无法使用后台服务并且不显示前台通知.

Unfortunately, it's not possible to use a background service and don't show a foreground notification on Android 8.0 and higher.

可能唯一可行的方法是将应用程序坚持使用Google API，例如语音操作API .

The only one way that it might work is if you stick your app to Google APIs such as Voice Actions API.

据我所知，目前尚无很好的解决方法，而像WhatsApp之类的大多数应用仍将Android API 24作为目标.

As far as I know there is no a good work around and most apps like WhatsApp are still targetting Android API 24.
