前边经过重重关卡，终于构建好了OpenHarmony系统。而编译好系统只是万里长征走完了第一步，真正的目的是为了实际的项目，以及在完成项目过程中完成具体的任务和实际解决的问题。
这里就开始介绍实际遇到的问题，以及对于它们的分析与解决。
在实际项目中，发现烧录系统后，对于语音唤醒功能进行测试时，并不能正常唤醒，此功能失效。关于语音唤醒这一部分的介绍参见：
由于笔者也是初次接触OpenHarmony，因此对于此问题采用最直接的方法，从系统日志入手。日志（log）如下（日志文件内容很大，只贴出相关的部分内容）：

（1）“get adapter device from hal failed, ret:0”
以“get adapter device from hal failed”为关键字，在OpenHarmony源码根目录下进行搜索，结果如下：
ph@ph-virtual-machine:~/OpenHarmony_Source$ grep -rn "get adapter device from" ./
./drivers/peripheral/intelligent_voice/hdi_service/trigger/intell_voice_trigger_manager_impl.cpp:109: INTELLIGENT_VOICE_LOGE("get adapter device from hal failed, ret:%{public}d", ret);
./drivers/peripheral/intelligent_voice/hdi_service/engine/intell_voice_engine_manager_impl.cpp:101: INTELLIGENT_VOICE_LOGE("get adapter device from hal failed");
由于日志中带有“ret:0”，因此是第1个搜素结果。看一下./drivers/peripheral/intelligent_voice/hdi_service/trigger/intell_voice_trigger_manager_impl.cpp文件第109行内容，代码如下：
int32_t IntellVoiceTriggerManagerImpl::LoadAdapter(const IntellVoiceTriggerAdapterDsecriptor &descriptor,
sptr<IIntellVoiceTriggerAdapter> &adapter)
{
std::lock_guard<std::mutex> lock(mutex_);
if (inst_ == nullptr) {
INTELLIGENT_VOICE_LOGE("inst is nullptr");
return HDF_FAILURE;
}
auto it = halAdapters_.find(descriptor.adapterName);
if (it != halAdapters_.end()) {
INTELLIGENT_VOICE_LOGW("adapter %{public}s already exist", descriptor.adapterName.c_str());
inst_->UnloadAdapter(descriptor);
it->second = nullptr;
halAdapters_.erase(it);
}
std::unique_ptr<ITrigger> triggerAdapterDevice = nullptr;
int32_t ret = inst_->LoadAdapter(descriptor, triggerAdapterDevice);
if (triggerAdapterDevice == nullptr) {
INTELLIGENT_VOICE_LOGE("get adapter device from hal failed, ret:%{public}d", ret);
return HDF_FAILURE;
}
adapter = sptr<IIntellVoiceTriggerAdapter>(new (std::nothrow) IntellVoiceTriggerAdapterImpl(
std::move(triggerAdapterDevice)));
if (adapter == nullptr) {
INTELLIGENT_VOICE_LOGE("new adapter failed");
return HDF_ERR_MALLOC_FAIL;
}
halAdapters_[descriptor.adapterName] = adapter;
return HDF_SUCCESS;
}
IntellVoiceTriggerManagerImpl::LoadAdapter()中的以下一行打印出了日志信息：
INTELLIGENT_VOICE_LOGE("get adapter device from hal failed, ret:%{public}d", ret);相关上下文如下：
std::unique_ptr<ITrigger> triggerAdapterDevice = nullptr;
int32_t ret = inst_->LoadAdapter(descriptor, triggerAdapterDevice);
if (triggerAdapterDevice == nullptr) {
INTELLIGENT_VOICE_LOGE("get adapter device from hal failed, ret:%{public}d", ret);
return HDF_FAILURE;
}由代码可见，之所以会打印出此信息，是由于调用“inst_->LoadAdapter(descriptor, triggerAdapterDevice);”之后，triggerAdapterDevice仍然是nullptr。
（2）“intell_voice_trigger_manager_st:?IntellVoiceTriggerManagerStubLoadAdapter_ failed, error code is -1”
这次不直接搜索，而是直接找到Open Harmony源码根目录/out/rk3588/gen/drivers/interface/intelligent_voice/trigger/v1_0/intell_voice_trigger_manager_stub.cpp文件?。并在其中以“failed, error code is”为关键字进行搜索，可知其在以下函数中：
int32_t OHOS::HDI::IntelligentVoice::Trigger::V1_0::IntellVoiceTriggerManagerStub::IntellVoiceTriggerManagerStubLoadAdapter_(MessageParcel& intellVoiceTriggerManagerData, MessageParcel& intellVoiceTriggerManagerReply, MessageOption& intellVoiceTriggerManagerOption, sptr<OHOS::HDI::IntelligentVoice::Trigger::V1_0::IIntellVoiceTriggerManager> impl)
{
if (intellVoiceTriggerManagerData.ReadInterfaceToken() != OHOS::HDI::IntelligentVoice::Trigger::V1_0::IIntellVoiceTriggerManager::GetDescriptor()) {
HDF_LOGE("%{public}s: interface token check failed!", __func__);
return HDF_ERR_INVALID_PARAM;
}
IntellVoiceTriggerAdapterDsecriptor descriptor;
if (!IntellVoiceTriggerAdapterDsecriptorBlockUnmarshalling(intellVoiceTriggerManagerData, descriptor)) {
HDF_LOGE("%{public}s: read descriptor failed!", __func__);
return HDF_ERR_INVALID_PARAM;
}
sptr<OHOS::HDI::IntelligentVoice::Trigger::V1_0::IIntellVoiceTriggerAdapter> adapter;
if (impl == nullptr) {
HDF_LOGE("%{public}s: impl is nullptr!", __func__);
return HDF_ERR_INVALID_PARAM;
}
int32_t intellVoiceTriggerManagerRet = impl->LoadAdapter(descriptor, adapter);
if (intellVoiceTriggerManagerRet != HDF_SUCCESS) {
HDF_LOGE("%{public}s failed, error code is %{public}d", __func__, intellVoiceTriggerManagerRet);
return intellVoiceTriggerManagerRet;
}
if (adapter == nullptr) {
HDF_LOGE("%{public}s: parameter adapter is nullptr!", __func__);
return HDF_ERR_INVALID_PARAM;
}
if (!intellVoiceTriggerManagerReply.WriteRemoteObject(OHOS::HDI::ObjectCollector::GetInstance().GetOrNewObject(adapter, OHOS::HDI::IntelligentVoice::Trigger::V1_0::IIntellVoiceTriggerAdapter::GetDescriptor()))) {
HDF_LOGE("%{public}s: write adapter failed!", __func__);
return HDF_ERR_INVALID_PARAM;
}
return intellVoiceTriggerManagerRet;
}
相关代码片段如下：
int32_t intellVoiceTriggerManagerRet = impl->LoadAdapter(descriptor, adapter);
if (intellVoiceTriggerManagerRet != HDF_SUCCESS) {
HDF_LOGE("%{public}s failed, error code is %{public}d", __func__, intellVoiceTriggerManagerRet);
return intellVoiceTriggerManagerRet;

以“intell_voice_trigger_manager_pr”为关键字，在OpenHarmony源码根目录下进行搜索，在众多结果中定位到：

./out/rk3588/gen/drivers/interface/intelligent_voice/trigger/v1_0/intell_voice_trigger_manager_proxy.cpp:26:#define HDF_LOG_TAG intell_voice_trigger_manager_proxy
打开
./out/rk3588/gen/drivers/interface/intelligent_voice/trigger/v1_0/intell_voice_trigger_manager_proxy.cpp文件 ，并在其中以“failed, error code is”为关键字进行搜索，可知其在以下函数中：
int32_t OHOS::HDI::IntelligentVoice::Trigger::V1_0::IntellVoiceTriggerManagerProxy::LoadAdapter_(const IntellVoiceTriggerAdapterDsecriptor& descriptor, sptr<OHOS::HDI::IntelligentVoice::Trigger::V1_0::IIntellVoiceTriggerAdapter>& adapter, const sptr<IRemoteObject> remote)

相关代码片段如下：

}（4）“TriggerConnector: [TriggerConnector:42]: failed to load adapter, adapterName is primary”
以“failed to load adapter, adapterName”为关键字，在OpenHarmony源码根目录下进行搜索，在众多结果中定位到：
./foundation/ai/intelligent_voice_framework/services/intell_voice_trigger/server/connector_mgr/trigger_connector.cpp:42: INTELL_VOICE_LOG_ERROR("failed to load adapter, adapterName is %{public}s", desc_.adapterName.c_str());
./foundation/ai/intelligent_voice_framework/services/intell_voice_trigger/server/connector_mgr/trigger_connector.cpp:108: INTELL_VOICE_LOG_ERROR("failed to load adapter, adapterName is %{public}s", desc_.adapterName.c_str());
打开
./foundation/ai/intelligent_voice_framework/services/intell_voice_trigger/server/connector_mgr/trigger_connector.cpp文件 。根据上边的信息，该文件中共有两处可以产生此日志。到底是哪一处？笔者更倾向于第一处，即构造函数中。代码如下：
TriggerConnector::TriggerConnector(const IntellVoiceTriggerAdapterDsecriptor &desc)
{
desc_.adapterName = desc.adapterName;
auto mgr = IIntellVoiceTriggerManager::Get();
if (mgr != nullptr) {
mgr->LoadAdapter(desc_, adapter_);
if (adapter_ == nullptr) {
INTELL_VOICE_LOG_ERROR("failed to load adapter, adapterName is %{public}s", desc_.adapterName.c_str());
}
} else {
INTELL_VOICE_LOG_INFO("can not get intell voice trigger manager");
}
}
至此，与语音唤醒即intelligent voice相关的日志及其出处（出自于哪个文件中的哪个函数）就弄清楚了。下一回开始对于函数的调用流程进行分析。
