Question

我试图在我开发的表盘上添加一些配置，但是达到了完全停顿状态。配置将您带到必须选择城市的页面。我已经添加了一个app.js页面，该页面可以捕获此值＆amp;将其重定向到表盘：

Pebble.addEventListener("webviewclosed",
  function(e) {
    //Get JSON dictionary
    var configuration = JSON.parse(decodeURIComponent(e.response));
    console.log("[DBUG] Configuration window returned: " + JSON.stringify(configuration) + " " + configuration.basic);

    //Send to Pebble, persist there
    Pebble.sendAppMessage(
      {'KEY_CITY': configuration.basic},
      function(e) {
        console.log("[DBUG] Settings data sent successfully ");
      },
      function(e) {
        console.log("[FAIL] Settings feedback failed!");
      }
    );
  }

）;

这很好用，日志包含正确的选定城市。我还注意到调用了in_recv_handler回调函数：

[PHONE] pebble-app.js:?: Skylines__0.0/pebble-js-app.js:12 [DBUG]     Configuration window returned: {"basic":"Brussels"} Brussels
[DEBUG] main.c:106: [DBUG] in_recv_handler - EMPTY TUPLE
[PHONE] pebble-app.js:?: Skylines__0.0/pebble-js-app.js:18 [DBUG] Settings data sent successfully

在我的C代码中，事情发生了可怕的错误： appmessage似乎在init（）部分正确初始化：

app_message_register_inbox_received(in_recv_handler);
  app_message_register_inbox_dropped(inbox_dropped);
  app_message_open(app_message_inbox_size_maximum(), app_message_outbox_size_maximum());

in_recv_handler是问题所在：

static void in_recv_handler(DictionaryIterator *iterator, void *context) {

  //Get data
  Tuple *tup = dict_read_first(iterator);
  if (tup != NULL) {  
    APP_LOG(APP_LOG_LEVEL_DEBUG, "[DBUG] in_recv_handler - NONEMPTY TUPLE");
    process_tuple(tup);
  }
  else { APP_LOG(APP_LOG_LEVEL_DEBUG, "[DBUG] in_recv_handler - EMPTY TUPLE"); }
}

元组/字典总是空的。所以app.js和字典加载之间似乎出现了问题，但我没有任何线索......

问：Pebble + AppMessage提供空字典
