GrantPermissionCallable:Permission:android.permission.SET_TIME无法授予

时间:2017-12-28 19:18:29

标签: android junit android-manifest android-support-library android-permissions

我尝试使用新GrantPermissionRule作为最新支持库的一部分。

在我的清单中,我声明了以下内容:

<uses-permission android:name="android.permission.SET_TIME"/>
在我的代码中,我打电话:

@Rule
public GrantPermissionRule mPermissionRule = GrantPermissionRule.grant(Manifest.permission.SET_TIME);

但是当我运行测试时,我看到了错误:

我的build.gradle更新了以下几行:

androidTestCompile 'com.android.support.test:runner:1.0.1'
androidTestCompile 'com.android.support.test:rules:1.0.1'
androidTestCompile 'com.android.support.test.espresso:espresso-core:3.0.0'

有任何建议或解决方案吗?

SET_TIMEa signature|privileged-level permission。无论是使用requestPermissions()还是GrantPermissionRule

,您都无法在运行时请求它

并且,除非您正在构建自己的固件或计划由root用户在特权分区上安装您的应用程序,否则您也可以从清单中删除<uses-permission>元素。

我想出了一种方法来“操纵”系统时间如果您使用模拟器

如果您在启动模拟器之前设置/更改主机系统时间,模拟器将占用主机时间。

这样我就可以在我的 Windows 上将时间设置为我想要的时间,然后启动模拟器并执行测试。
