Question

我想在BlackBerry 10 OS的通话时间内录制通话语音。为此，我使用了Telephony Phone和Call State Listener。我开始发现呼叫状态＆＃34;已连接＆＃34;呼叫时停止＆＃34;断开连接＆＃34;。

但是在开始时记录器每次只记录160Byte的数据。并且在停止时刻录音机显示＆＃34;已经毫无准备＆＃34;。

为此我使用recorder.prepare（）但它仍然不适合我。请建议并帮助我。这是代码

void ApplicationHeadless::onCallUpdated(const Call &call)
{
    QMetaObject MetaCallTypeObject = CallType::staticMetaObject;
    QMetaEnum CallTypeEnum = MetaCallTypeObject.enumerator(
            MetaCallTypeObject.indexOfEnumerator("Type"));

    QMetaObject MetaCallStateObject = CallState::staticMetaObject;
    QMetaEnum CallStateEnum = MetaCallStateObject.enumerator(
            MetaCallStateObject.indexOfEnumerator("Type"));

    CallType::Type CurrentCallType = call.callType();
    CallState::Type CurrentCallState = call.callState();

    QString conn = "Connected";
    QString dcon = "Disconnected";
    QDateTime now = QDateTime::currentDateTime();
    bb::multimedia::AudioRecorder recorder;

    if (conn.compare(CallStateEnum.valueToKey(CurrentCallState)) == 0) {
        recorder.setOutputUrl(QUrl("/tmp/" + now.toString() + ".m4a"));
        recorder.setOutputUrl(QUrl("file://" + QDir::currentPath() + "/data/recording121.m4a"));
        recorder.record();
    }

    if (dcon.compare(CallStateEnum.valueToKey(CurrentCallState)) == 0) {
        recorder.reset();
    }
}

提前致谢..
