为三星手机上的应用设置设备所有者权限

Question

I am trying to set my app as device owner via adb with this command:

dpm set-device-owner pl.my.packet/pl.my.packet.receivers.AdminReceiver

and then I see that error:

java.lang.SecurityException: Neither user 2000 nor current process has com.samsung.android.knox.permission.KNOX_PROXY_ADMIN_INTERNAL.,com.sec.enterprise.permission.MDM_PROXY_ADMIN_INTERNAL
    at android.os.Parcel.readException(Parcel.java:1693)

    at com.android.internal.os.RuntimeInit.main(RuntimeInit.java:301)

Phone: Samsung S7 Edge, not rooted, without any Google account linked.

I searched for other usefull threads for me but found nothing, I tried with these permissions:

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="com.sec.enterprise.permission.MDM_PROXY_ADMIN_INTERNAL"/>
<uses-permission android:name="com.samsung.android.knox.permission.KNOX_PROXY_ADMIN_INTERNAL"/>
<uses-permission android:name="com.samsung.accessory.permission.ACCESSORY_FRAMEWORK" />

Answer 1

I had a similar error and found that I had typo-ed the package and receiver name in dpm set-device-owner command. I don't think you need the package name in your receiver's name. Maybe dpm set-device-owner pl.my.packet/.AdminReceiver ?

Answer 2

not rooted

You cannot do that as you are clearly told:

Neither user 2000 nor current process has com.samsung.android.knox.permission.KNOX_PROXY_ADMIN_INTERNAL.,com.sec.enterprise.permission.MDM_PROXY_ADMIN_INTERNAL

And you cannot just add random permissions and expect it to work. I assume both are at least signature type or system . And you cannot have either on non rooted or not having system certificate.
