java.lang.SecurityException异常：权限拒绝：getIntentSender（）在测试使用UiAutomation时 [英] java.lang.SecurityException: Permission Denial: getIntentSender() when using UiAutomation in a test

问题描述

每当我尝试使用 UiAutomation 通过任何测试 getInstrumentation（）getUiAutomation（），该进程崩溃与此异常：

Whenever I try to use UiAutomation in any test through getInstrumentation().getUiAutomation(), the process crashes with this exception:

java.lang.SecurityException: Permission Denial: getIntentSender() from pid=30334, uid=2000, (need uid=1000) is not allowed to send as package android
        at android.os.Parcel.readException(Parcel.java:1540)
        at android.os.Parcel.readException(Parcel.java:1493)
        at android.app.IUiAutomationConnection$Stub$Proxy.disconnect(IUiAutomationConnection.java:225)
        at android.app.UiAutomation.disconnect(UiAutomation.java:240)
        at android.app.Instrumentation.finish(Instrumentation.java:197)
        at android.test.InstrumentationTestRunner.onStart(InstrumentationTestRunner.java:575)
        at android.app.Instrumentation$InstrumentationThread.run(Instrumentation.java:1837)

任何想法，为什么？我使用的摇篮通过Android的工作室，尝试过各种版本，直接调用它通过亚行，即使没有任何外部依赖（显然至少有18 SDK）...永远崩溃。

Any idea why? I'm using Gradle through Android Studio, tried various versions, calling it directly through adb, even without any external dependency (and obviously with at least SDK 18)... Always crashing.

这是唯一的官方的例子，我发现： https://www.youtube.com /手表？v = _SlBHUW0ybM

推荐答案

这是不是为什么UIAutomator没有捕获错误，而是一个可能的解决方法，我找到了答案。当无障碍服务上我不能，因为我收到您所描述的错误得到一个UIAutomator转储。当我关掉话语提示和/或辅助功能设置交换机接入我不再得到许可拒绝错误，UIAutomator转储成功地工作。不知道这是否会帮助你，但我可以在棒棒堂（的Nexus 5）无障碍服务每次重现您的问题ON。

This isn't an answer for why UIAutomator isn't catching the error, but rather a possible workaround that I found. When accessibility services are on I am unable to get an UIAutomator dump because I receive the error you described. When I turn off TalkBack and/or Switch Access in the Accessibility settings I no longer get the Permission Denial error and UIAutomator dump works successfully. Not sure if this will help you, but I can reproduce your issue every time with accessibility services ON in Lollipop(Nexus 5).
