Java Android permission.interactive_跨_用户拒绝

我有一个奇怪的android权限拒绝，如下所示：

java.lang.SecurityException: Permission Denial: isUserRunning() from pid=1078, uid=10284 requires android.permission.INTERACT_ACROSS_USERS

我没有找到任何关于

android.permission.interaction\u跨用户的信息

仅

android.permission.interaction\u跨用户的信息

以下是完整的日志：

java.lang.SecurityException: Permission Denial: isUserRunning() from pid=25403, uid=10310 requires android.permission.INTERACT_ACROSS_USERS

    at android.os.HandlerThread.run(HandlerThread.java:61)

我已将此添加到我的清单中：

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

<!-- @SystemApi @hide Allows an application to call APIs that allow it to do interactions
     across the users on the device, using singleton services and
     user-targeted broadcasts.  This permission is not available to
     third party applications. -->
<permission android:name="android.permission.INTERACT_ACROSS_USERS"
    android:protectionLevel="signature|system|privileged" />

<!-- @hide Fuller form of {@link android.Manifest.permission#INTERACT_ACROSS_USERS}
     that removes restrictions on where broadcasts can be sent and allows other
     types of interactions. -->
<permission android:name="android.permission.INTERACT_ACROSS_USERS_FULL"
    android:protectionLevel="signature" />

您应该在Android运行时实现权限请求，特别是对于棉花糖或更高版本。 如果您没有实现运行时权限，那么您的应用程序将崩溃或无法在有棉花糖的设备上正常工作

我希望您现在非常了解Marshmallow中的运行时权限概念。让我们了解以下代码：

int currentAPIVersion = Build.VERSION.SDK_INT;
if(currentAPIVersion>=android.os.Build.VERSION_CODES.M)
 {
    if (ContextCompat.checkSelfPermission(context, Manifest.permission.INTERACT_ACROSS_USERS) != PackageManager.PERMISSION_GRANTED) {
        if (ActivityCompat.shouldShowRequestPermissionRationale((Activity) context, Manifest.permission.INTERACT_ACROSS_USERS)) {
            AlertDialog.Builder alertBuilder = new AlertDialog.Builder(context);
            alertBuilder.setCancelable(true);
            alertBuilder.setTitle("Permission necessary");
            alertBuilder.setMessage("Interact across users permission is necessary to this app");
            alertBuilder.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    ActivityCompat.requestPermissions((Activity)context, new String[]{Manifest.permission.INTERACT_ACROSS_USERS}, MY_PERMISSIONS_REQUEST_INTERACT_ACROSS_USERS);
                }
            });
            AlertDialog alert = alertBuilder.create();
            alert.show();
        } else {
            ActivityCompat.requestPermissions((Activity)context, new String[]{Manifest.permission.INTERACT_ACROSS_USERS}, MY_PERMISSIONS_REQUEST_INTERACT_ACROSS_USERS);
        }
    }
}


 @Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    switch (requestCode) {
 case MY_PERMISSIONS_REQUEST_INTERACT_ACROSS_USERS:
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
               // do something here...
               Toast.makeText(getApplicationContext(), "Permission granted", Toast.LENGTH_SHORT).show();
        } else {
         //code for deny
         Toast.makeText(getApplicationContext(), "Permission denied", Toast.LENGTH_SHORT).show();

}
         break;
    }
}

TL；博士此堆栈跟踪不属于您的应用程序，或者您需要您没有的权限。要了解这些权限，请阅读其余部分。

虽然米歇尔可能已经找到了答案，但我决定回答这个问题，因为它可能对其他人有用。提到的权限是签名|系统级权限。要了解有关不同类型权限的更多信息，请阅读以下内容：

基本上，使用多用户API需要这些权限，例如：

Context.startActivityAsUser(Intent, UserHandle)
Context.bindServiceAsUser(Intent, …, UserHandle)
Context.sendBroadcastAsUser(Intent, … , UserHandle)
Context.startServiceAsUser(Intent, …, UserHandle)

要了解更多信息，请阅读以下内容：

由于该错误，Michele得出结论，他必须将这些权限添加到清单中（我们将看到应用程序如何授予这些权限），但他定义了这些权限（要了解有关定义权限的更多信息，请阅读此：）：

就这些吗？还没有

自android 8.0以来，在priv app下授予应用程序的权限存在一些复杂问题，您可以在此处阅读：

的可能重复，除非您正在使用

com.android.launcher3

，Java堆栈跟踪似乎不是来自您的应用程序。因此@Commonware我能做什么？您可以从解释堆栈跟踪与您的应用程序的关系开始。当您在Android Studio中打开清单时，您应该会看到一个“合并清单”按钮。你会看到很多不同的颜色。查找跨用户声明INTERACT_的权限，并找出它来自什么清单。这意味着如果你使用一个库，它从哪里来？清单没有跨用户的交互，它会导致错误！无法跨用户进行交互
