我已使用以下权限将应用程序启动为

I have used following permission to make the app a launcher

<intent-filter>
 <action android:name="android.intent.action.MAIN" />               
 <category android:name="android.intent.category.HOME" />
 <category android:name="android.intent.category.DEFAULT" />
 <category android:name="android.intent.category.MONKEY" />
</intent-filter>

推荐答案

无法更改用户首选项. Google不允许开发人员更改用户偏好.

It is not possible to change the user preferences. Google does not allow developer to change user preferences.

一种解决方法可能会有用，您可以通过服务检查您的应用程序是否为默认启动器，然后提示用户将您的应用程序选择为默认启动器.

A workaround may be useful, you can check for if your application is default launcher through a service and then prompt user to choose your application as default.

您可以在此处中找到如何检查您的应用程序是否为默认启动器(尝试过此方法，它对我有用)或此处

然后，如果不是默认启动器，则可以提示用户选择您的应用程序. 此处提供了解决方法.
