Android 在 Android 8.0 Oreo 上崩溃：SecurityException：权限被拒绝：null 以用户 450 的身份请求运行但正在从用户 0 调用

Question

我将 phone 升级为 Android 奥利奥。当我运行我的应用程序在此设备上时。我的应用程序崩溃了。虽然它运行在 Android 7 及更低版本的设备上很好。

这是日志：

Answer 1

从 this answer, and looking at the sources of UserHandle.java 中总结一下，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。 table:

所以你需要在 AndroidManifest.xml 中做什么很大程度上取决于你需要支持什么 API，因为更高的 > 23 API 也需要 android:permissionGroup= definition，对于非正常（"dangerous"）权限...

为了能够保持 INTERACT_ACROSS_USERS，您的应用必须通过固件的签名密钥进行签名，或者必须安装在系统分区上。

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

因此最后将此添加到您的清单文件中：

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

希望对您有所帮助...

我遇到过这个问题。

在我的例子中，在执行 startActivity 之后，应用程序抛出以下异常：

经过几个小时的调查，我发现我的 class BaseActivity，它被所有应用程序活动扩展，已经实现了一个名为 getUserId 的受保护方法，如下例所示：

 class BaseActivity extends AppCompatActivity {

   ...

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

我刚刚将方法名称更改为另一个，应用程序又恢复工作了：

 class BaseActivity extends AppCompatActivity {

   ...

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

我在基础 classes 中找不到任何同名的方法，但正如我们在堆栈跟踪中看到的那样，这个方法可能是由 Reflection 调用的。

其他重要的想法 是只有实现任何 EditText 视图的活动才会抛出异常。在 API 26.

中执行 Autofill Framework 后出现问题

Answer 3

我在 kotlin 中遇到过同样的问题。仅当在 activity 中实现 Edittext 并且在此 Class 或其父级 class 中具有 getUserId() 方法时才会发生此问题。将 getUserId() 更改为 getUserIdd() 解决了我的问题。

在 Kotlin 中我有一个变量

var userId=0

我改成了

var userIdd=0

解决了我的问题。
