Подскажите, как-то вообще реально отследить ответ со стороны вызываемого номера?
гуглил и нагуглил:
Код: Выделить всё
ACTION_CALL
Added in API level 1
String ACTION_CALL
Activity Action: Perform a call to someone specified by the data.
Input: If nothing, an empty dialer is started; else getData() is URI of a phone number to be dialed or a tel: URI of an explicit phone number.
Output: nothing.
Note: there will be restrictions on which applications can initiate a call; most applications should use the ACTION_DIAL.
Note: this Intent cannot be used to call emergency numbers. Applications can dial emergency numbers using ACTION_DIAL, however.
Note: if you app targets M and above and declares as using the CALL_PHONE permission which is not granted, then attempting to use this action will result in a SecurityException.
Constant Value: "android.intent.action.CALL"
Спасибо.
