如何在设备启动时启动android应用程序? [英] How can I start android application on device boot?

问题描述

我需要启动android前台服务，并在设备启动时从该服务启动活动.我已经广泛地搜索了web和stackoverflow并尝试了不同的建议，但是很奇怪我无法使此功能正常工作.

I have need to start android foreground service, and launch activity from that service on device boot. I have extensively searched web and stackoverflow and tried different suggestions but it is very strange that I can not make this functionality work.

我不明白自己在做什么.

I can not understand what I am doing wrong.

下面是我项目中的代码和清单文件的内容.

Below is the code from my project and the content of manifest file.

我做错了什么以及如何解决，可以在大多数android设备上使用的功能?

what I am doing wrong and how to solve it, the functionality to work on most android devices?

这是我的AndroidManifest.xml:

This is my AndroidManifest.xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="kor.location.tracker">

推荐答案

在清单文件中添加了启动权限(请参见下面的代码)后，BroadcastReceiver开始获取启动完成事件，并且该服务已成功启动.为使该解决方案有效(如@ErenTüfekçi所建议)，我必须在我的应用程序的电话设置中启用自动启动权限.如果有人有解决方案，如何以编程方式启用它，请告诉我们.谢谢.

After I added the boot permissions in manifest file (see code below), BroadcastReceiver started to get boot completed event and the service is starting successfully. For the solution to work (as suggested by @Eren Tüfekçi) I had to enable auto start permission in phone settings for my application. If anyone has a solution, how to enable it programmatically, please let us know. Thank you.
