android - AIDL, bind and unbind IExtendedNetworkService Service -
i use aidl interface iextendednetworkservice ussd code. application work after reboot device. tried bindservice after install app didn't work. problem how way bind service without reboot device . code: interface:
package com.android.internal.telephony; interface iextendednetworkservice { void setmmistring(string number); charsequence getmmirunningtext(); charsequence getusermessage(charsequence text); void clearmmistring(); } service
