How to parse USSD request response in Android using logcat?

Question

Java

I took an example of this code - https : //github.com/djkevincr/sep_project/tree/mast ... what should have been found in the logs is:

W/Trace   (  679): Unexpected value from nativeGetEnabledTags: 0
D/CallManager(  679):  handleMessage msgid:114
D/CallManager(  679):  handleMessage (EVENT_MMI_COMPLETE)
D/PhoneGlobals(  679): onMMIComplete()...
D/PhoneUtils(  679): displayMMIComplete: state=COMPLETE
D/PhoneUtils(  679): Extended NW displayMMIComplete removeMsg
D/PhoneUtils(  679): - using text from MMI message: 'Balans: 321.75.'
D/PhoneUtils(  679): MMI code has finished running.
D/PhoneUtils(  679): Extended NW displayMMIInitiate (Balans: 321.75.)
V/Provider/Settings(  679):  from settings cache , name = security_locker , value = null

There is a look at the Habr, the first thing that caught my eye:

// do not write all imports, I will only write that do not forget to include the USSD class
import com.example.android.UssdMessage.USSD;

But this class is not used if you write
the line in the Manifest

<uses-permission android:name="android.permission.CALL_PRIVILEGED"></uses-permission>

Underlined in red, and I don’t see the point of it, since it’s the same thing CALL_PHONEbut with the ability to call emergency numbers.
