检测broadcastreceiver

Question

我正在使用broadcastreceiver来检测拨出呼叫并在它开始拨号后启动服务。服务已启动。现在我想在通话结束或拨号结束后停止服务。

@Override
public void onReceive(Context context, Intent intent) {

        if (Intent.ACTION_NEW_OUTGOING_CALL.equals(intent.getAction())) {

        intent = new Intent(context, serv.class);
        context.startService(intent);
   }

    if(intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(
            TelephonyManager.EXTRA_STATE_IDLE)) {
        intent = new Intent(context, serv.class);
        context.stopService(intent);

    }
 }

    try {
                //to Fix Lolipop broadcast issue.
                long subId = intent.getLongExtra("subscription", Long.MIN_VALUE);
                if (subId < Integer.MAX_VALUE) {
                    if (intent.getAction().equals("android.intent.action.NEW_OUTGOING_CALL")) {
