Android13高通平台拨打/接听只有免提模式，无听筒模式

背景：由于没有听筒，所以直接在电话状态下只有免提模式；

修改记录：

java 复制代码

qssi/packages/services/Telecomm/src/com/android/server/telecom/CallAudioRouteStateMachine.java

private void createStates(int earpieceControl) {
        switch (earpieceControl) {
            case EARPIECE_FORCE_DISABLED:
                mDoesDeviceSupportEarpieceRoute = false;
                break;
            case EARPIECE_FORCE_ENABLED:
                mDoesDeviceSupportEarpieceRoute = false;//modified
                break;
            default:
                mDoesDeviceSupportEarpieceRoute = false;//checkForEarpieceSupport();//modified
        }

        addState(mActiveEarpieceRoute);
        addState(mActiveHeadsetRoute);
        addState(mActiveBluetoothRoute);
        addState(mActiveSpeakerRoute);
        addState(mRingingBluetoothRoute);
        addState(mQuiescentEarpieceRoute);
        addState(mQuiescentHeadsetRoute);
        addState(mQuiescentBluetoothRoute);
        addState(mQuiescentSpeakerRoute);


        mStateNameToRouteCode = new HashMap<>(8);
        mStateNameToRouteCode.put(mQuiescentEarpieceRoute.getName(), ROUTE_EARPIECE);
        mStateNameToRouteCode.put(mQuiescentBluetoothRoute.getName(), ROUTE_BLUETOOTH);
        mStateNameToRouteCode.put(mQuiescentHeadsetRoute.getName(), ROUTE_WIRED_HEADSET);
        mStateNameToRouteCode.put(mQuiescentSpeakerRoute.getName(), ROUTE_SPEAKER);
        mStateNameToRouteCode.put(mRingingBluetoothRoute.getName(), ROUTE_BLUETOOTH);
        mStateNameToRouteCode.put(mActiveEarpieceRoute.getName(), ROUTE_EARPIECE);
        mStateNameToRouteCode.put(mActiveBluetoothRoute.getName(), ROUTE_BLUETOOTH);
        mStateNameToRouteCode.put(mActiveHeadsetRoute.getName(), ROUTE_WIRED_HEADSET);
        mStateNameToRouteCode.put(mActiveSpeakerRoute.getName(), ROUTE_SPEAKER);

        mRouteCodeToQuiescentState = new HashMap<>(4);
        mRouteCodeToQuiescentState.put(ROUTE_EARPIECE, mQuiescentEarpieceRoute);
        mRouteCodeToQuiescentState.put(ROUTE_BLUETOOTH, mQuiescentBluetoothRoute);
        mRouteCodeToQuiescentState.put(ROUTE_SPEAKER, mQuiescentSpeakerRoute);
        mRouteCodeToQuiescentState.put(ROUTE_WIRED_HEADSET, mQuiescentHeadsetRoute);
    }

之后验证来电/通话只有免提模式，点击免提按钮也是不能切换的；
