着信が検出されたときに新しいアクティビティを開始する方法。CALL_STATE_RINGING
以下のコードでは、状態で新しいアクティビティを開始したいと思います
public String getCurrentCallState(final TelephonyManager mytelMgr) {
int callState = mytelMgr.getCallState();
String callStateString = "NOTKNOWN";
switch (callState) {
case TelephonyManager.CALL_STATE_IDLE:
callStateString = "IDLE";
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
callStateString = "OFFHOOK";
break;
case TelephonyManager.CALL_STATE_RINGING:
callStateString = "RINGING";
break;
}
}
* CALL_STATE_RINGING *状態でいくつか変更を加えましたが、機能していません。電話が来るたびに、私のアプリは終了します。実際、着信が鳴っている間にそのアクティビティを呼び出したいと思います。
