最近在 Android R(Android 11)系统上执行以前写的Espresso UI(AndroidX)单元测试用例的时候，发现在 联想拯救者电竞手机Pro(128GB) 系统版本 12.5.225上，如果测试用例申请了通讯录写入权限，如下：
|
1 |
<uses-permission android:name="android.permission.WRITE_CONTACTS" /> |
那么测试用例执行的时候，会报告如下错误：
|
1 |
Test running failed:Process crashed. |
详细的logcat日志如下：

目前测试发现，即使通过GrantPermissionRule授予权限，也是没用的，代码根本来不及执行，应用就一下被系统杀死了。
目前只能是不测试这部分功能。

@Rule public final GrantPermissionRule rule = GrantPermissionRule.grant(android.Manifest.permission.WRITE_CONTACTS); |
在OPPO/VIVO/小米等手机上，需要手工开启 后台弹出界面权限 才能执行单元测试。有个思路是通过UI Automator来自动开启这个权限，暂时还需要测试一下。
