ikantech opened a new issue #3135: [Android] 0.28.0 fireEventSync同步事件回调Java层无法收到
URL: https://github.com/apache/incubator-weex/issues/3135
 
 
   经测试发现，nativeback等同步事件回调Java层无法收到，底层返回callbackid与Java层callbackid无法对应，所以无法触发回调。
   
   core_side_in_script.cpp :
   ```cpp
   void CoreSideInMultiProcess::OnReceivedResult(long callback_id,
                                                 std::unique_ptr<WeexJSResult> &result) {
     BackToWeexCoreQueue::IPCTask *ipc_task = new BackToWeexCoreQueue::IPCTask(
         IPCProxyMsg::ONRECEIVEDRESULT);
   
     auto temp = std::to_string(callback_id);
     ipc_task->addParams(temp.c_str(), temp.length());
     if (result != nullptr) {
       ipc_task->addParams(result->data.get(), result->length);
     }
     WeexEnv::getEnv()->m_back_to_weex_core_thread.get()->addTask(ipc_task);
   }
   ```
   这里传输的是字符串，而在返回WeexCore后，则直接转成了long
   
   script_bridge_in_multi_process.cpp: 
   ```cpp
   std::unique_ptr<IPCResult> OnReceivedResult(IPCArguments *arguments) {
     long callback_id = arguments->get<long>(0);
     std::unique_ptr<WeexJSResult> result;
   ```
   
   应该要由string转long
   
   ```cpp
   std::unique_ptr<IPCResult> OnReceivedResult(IPCArguments *arguments) {
     auto arg1 = std::unique_ptr<char[]>(getArumentAsCStr(arguments, 0));
     long callback_id = atol(arg1.get());
   ```
   
   由于我未深入了解weex底层，代码不一定正确，烦请官方修复，谢谢
