推荐答案

此问题的解决方案是您必须使设备具有root用户权限并修复文件许可权.您可以尝试按照提示中的建议进行操作(特别是如果没有选择生根"的话)，但在某些情况下，只有根"才能解决该问题.

The solution to this is that you must root your device and fix a file permission. You can try following the advice on the prompt (especially if rooting is not an option) but in some cases only a root will fix the issue.

将设备植根后，请打开adb shell并运行以下命令:

Once you have rooted your device open an adb shell and run the following:

su
mount -o remount,rw /system
chmod 4750 /system/bin/run-as
mount -o remount,ro /system

这修复了setuid权限，以便根据文件的所有者(即根)授予运行方式进程访问权限.

This fixes the setuid permission so that the run-as process is granted access based on the owner of the file (i.e. root).
