GrantPermissionRule 授予权限失败

Question

我正在编写测试 class 并且我正在尝试使用规则 GrantPermissionRule:

授予权限

@Rule
public GrantPermissionRule permissionsRule = GrantPermissionRule.grant(
        Manifest.permission.READ_EXTERNAL_STORAGE,
        Manifest.permission.WRITE_EXTERNAL_STORAGE);

但是我在测试执行开始时得到以下错误：

这是 logcat 输出（仅限错误）：

但这似乎只发生在我的 Android 6.0.1 的 Redmi 4 中。但是在 Samsung Galaxy Tab S 6.0.1 中它可以工作，在一些模拟器中也是如此...

我错过了什么？

Answer 1

找到解决方案。我必须在开发者选项菜单中授予权限：

Answer 2

The above-answered option wasn't available in my OPPO device.

但是有一个名为 "Disable Permissions Monitoring" 的选项具有相同的功能。

要解决此问题，请在开发人员选项

下打开 "Disbale Permission Functionality" 的选项

Answer 3

它的价值：对我来说，我只是忘记在应用程序的清单中指定权限。
