I want to hang up incoming call I detect it and then I want to hang it up.

The problem is that this: com.android.internal.telephony.ITelephony is not re

Answer 1

The ITelephony interface is internal, so you cannot get a standard reference to it. You could use reflection all the way, i.e.

TelephonyManager tm = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);

Method m1 = tm.getClass().getDeclaredMethod("getITelephony");
m1.setAccessible(true);
Object iTelephony = m1.invoke(tm);

Method m2 = iTelephony.getClass().getDeclaredMethod("silenceRinger"); 
Method m3 = iTelephony.getClass().getDeclaredMethod("endCall"); 

m2.invoke(iTelephony);
m3.invoke(iTelephony);

But either way those methods need the MODIFY_PHONE_STATE permission, which can only be granted to system apps. So I'm afraid it won't work anyway.

For kotlin:

 val tm = context.getSystemService(Context.TELEPHONY_SERVICE) as TelephonyManager
 val m1 = tm::class.java.getDeclaredMethod("getITelephony")
 m1.setAccessible(true)
 val telephonyService = m1.invoke(tm)
 val m2 = telephonyService::class.java.getDeclaredMethod("silenceRinger")
 val m3 = telephonyService::class.java.getDeclaredMethod("endCall")

 m2.invoke(telephonyService)
 m3.invoke(telephonyService)
