请求PACKAGE_USAGE_STATS的权限 [英] Request permission on PACKAGE_USAGE_STATS

问题描述

我想检查用户是否已授予我的应用程序使用 PACKAGE_USAGE_STATS 的权限。我目前正在做的是：

I want to check wheter the user have granted permission for my application to use PACKAGE_USAGE_STATS. What I am currently doing is this:

// Control that the required permissions is instantiated!
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ContextCompat.checkSelfPermission(this, Manifest.permission.PACKAGE_USAGE_STATS) != PackageManager.PERMISSION_GRANTED) {
    ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.PACKAGE_USAGE_STATS}, MULTIPLE_PERMISSION_GRANTED);
}

我已按照Android Developer部分的说明实现了requestPermissions，它正在运行适用于 ACCESS_FINE_LOCATION 。

I have implemented the requestPermissions as described in the Android Developer section and it is working just fine for ACCESS_FINE_LOCATION.

但是当我的应用程序请求权限时，它只显示 ACCESS_FINE_LOCATION 权限，而不是 PACKAGE_USAGE_STATS 任何人都可以解释原因吗？如果是这样，给我一个解决方案，我该怎么做？

But when my application request permissions it only shows the ACCESS_FINE_LOCATION permission and not the PACKAGE_USAGE_STATS can anyone explain why? And if so, give a solution to how I could do it?

我希望这两个权限都显示在如下对话框中：

I want both permissions to show up in a dialog box like this:

推荐答案

很遗憾，您无法申请 PACKAGE_USAGE_STATS 在运行时，就像你使用危险权限一样。用户需要通过Settings应用程序手动授予权限，如 UsageStatsManager 文档：

Unfortunately you can't request the PACKAGE_USAGE_STATS at runtime like you do with a dangerous permission. The user need to manually grant the permission through the Settings application as explained in the UsageStatsManager documentation:

此API需要权限
android.permission.PACKAGE_USAGE_STATS，这是系统级
权限，不会授予第三方应用。但是，
声明权限意味着有意使用API​​，设备的用户
可以通过设置应用程序授予权限。

This API requires the permission android.permission.PACKAGE_USAGE_STATS, which is a system-level permission and will not be granted to third-party apps. However, declaring the permission implies intention to use the API and the user of the device can grant permission through the Settings application.

您可以使用以下代码直接打开具有使用权限活动的应用程序：

You can directly open the Apps with usage access activity with this code:

startActivity(new Intent(Settings.ACTION_USAGE_ACCESS_SETTINGS));

这里您可以找到一个基本应用程序示例，其中显示了如何使用应用程序使用情况统计API。

Here you can find an example of a basic app that shows how to use App usage statistics API.
