Answer 1

Provide appropriate permission and add the ITelephony.java file

private void declinePhone(Context context) throws Exception {

        try {

            String serviceManagerName = "android.os.ServiceManager";
            String serviceManagerNativeName = "android.os.ServiceManagerNative";
            String telephonyName = "com.android.internal.telephony.ITelephony";
            Class telephonyClass;
            Class telephonyStubClass;
            Class serviceManagerClass;
            Class serviceManagerNativeClass;
            Method telephonyEndCall;
            Object telephonyObject;
            Object serviceManagerObject;
            telephonyClass = Class.forName(telephonyName);
            telephonyStubClass = telephonyClass.getClasses()[0];
            serviceManagerClass = Class.forName(serviceManagerName);
            serviceManagerNativeClass = Class.forName(serviceManagerNativeName);
            Method getService = // getDefaults[29];
            serviceManagerClass.getMethod("getService", String.class);
            Method tempInterfaceMethod = serviceManagerNativeClass.getMethod("asInterface", IBinder.class);
            Binder tmpBinder = new Binder();
            tmpBinder.attachInterface(null, "fake");
            serviceManagerObject = tempInterfaceMethod.invoke(null, tmpBinder);
            IBinder retbinder = (IBinder) getService.invoke(serviceManagerObject, "phone");
            Method serviceMethod = telephonyStubClass.getMethod("asInterface", IBinder.class);
            telephonyObject = serviceMethod.invoke(null, retbinder);
            telephonyEndCall = telephonyClass.getMethod("endCall");
            telephonyEndCall.invoke(telephonyObject);

        } catch (Exception e) {
            e.printStackTrace();
            Log.d("unable", "msg cant dissconect call....");

        }
