Android 8.0上的Android崩溃Oreo：SecurityException：Permission Denial：null要求以用户450身份运行，但是从用户0调用

Question

我将手机升级到Android Oreo。当我在这台设备上运行我的应用程序时。我的应用程序崩溃了。虽然它在Android 7和更低的设备上运行良好。

这是日志：

我遇到过这个问题。

就我而言，在执行results之后，应用程序抛出了以下异常：

startActivity

经过数小时的调查，我发现我的班级Fatal Exception: java.lang.SecurityException: Permission Denial: null asks to run as user 66853 but is calling from user 0; this requires android.permission.INTERACT_ACROSS_USERS_FULL

getUserId

我刚刚将方法名称更改为另一个，并且应用程序重新开始工作：

 class BaseActivity extends AppCompatActivity {

   ...

   protected int getUserId() {
     return getCurrentUserRepository().getId();
   }
 }

我在基类中找不到任何具有相同名称的方法，但我们可以在stacktrace中看到，此方法可能由反射调用。

其他重要的想法是只有实现任何 class BaseActivity extends AppCompatActivity { ... protected int getApplicationUserId() { return getCurrentUserRepository().getId(); } } 视图的活动才会抛出异常。在 API 26 中实施Autofill Framework后出现此问题。

Answer 2

总结this回答，并查看UserHandle.java的来源，我们看到了框架用户ID的含义。

# | @UserIdInt            | Value  | Status     | Description |
# | --------------------- | ------ | ---------- | ------------| 
# | USER_OWNER            | 0      | deprecated | "owner" user of the device
# | USER_SYSTEM           | 0      | ok         | "system" user of the device
# | USER_ALL              | -1     | ok         | ALL users on the device
  | USER_CURRENT          | -2     | ok         | the currently active user
# | USER_CURRENT_OR_SELF  | -3     | ok         | id from which we would like to send to the current user
# | USER_NULL             | -10000 | ok         | An undefined user id

然后，要了解android:protectionLevel="signature"的含义，您必须阅读有关permission-element的页面。表中总结了这一点：

因此，您在AndroidManifest.xml中需要做的事情很大程度上取决于您需要支持哪些API，因为更高的＆gt;对于非正常（“危险”）权限，23 API也需要android:permissionGroup= definition ...

为了能够举行 INTERACT_ACROSS_USERS ，您的应用必须由固件的签名密钥签名，或者必须安装在系统分区上。

为了能够举行 INTERACT_ACROSS_USERS_FULL ，您的应用必须通过固件的签名密钥进行签名。

因此最后在您的清单文件中添加：

<permission android:name="android.permission.INTERACT_ACROSS_USERS_FULL" android:protectionLevel="signature"/>

希望它有所帮助...

Answer 3

我在科特林遇到了同样的问题。仅当在活动中实现Edittext且该类或其父类中具有getUserId（）方法时，才会发生此问题。将 getUserId（）更改为 getUserIdd（）可以解决我的问题。

在Kotlin中，我有一个变量

var userId=0

我将其更改为

var userIdd=0

解决了我的问题。
