当我像这样在 Pebble 上记录错误时:

static void message_dropped(AppMessageResult reason, void *context) {
  APP_LOG(APP_LOG_LEVEL_DEBUG, "Message dropped. Reason: %d", reason);
}

我只是得到错误消息的 int 值。有没有一种简单的方法来记录枚举的文本?喜欢:

static void message_dropped(AppMessageResult reason, void *context) {
  APP_LOG(APP_LOG_LEVEL_DEBUG, "Message dropped. Reason: %fancy", reason);
}
// Would return "APP_MSG_BUFFER_OVERFLOW"

没有 API 函数可以做到这一点。您可以将此函数用于AppMessageResult枚举:

char *translate_error(AppMessageResult result) {
  switch (result) {
    case APP_MSG_OK: return "APP_MSG_OK";
    case APP_MSG_SEND_TIMEOUT: return "APP_MSG_SEND_TIMEOUT";
    case APP_MSG_SEND_REJECTED: return "APP_MSG_SEND_REJECTED";
    case APP_MSG_NOT_CONNECTED: return "APP_MSG_NOT_CONNECTED";
    case APP_MSG_APP_NOT_RUNNING: return "APP_MSG_APP_NOT_RUNNING";
    case APP_MSG_INVALID_ARGS: return "APP_MSG_INVALID_ARGS";
    case APP_MSG_BUSY: return "APP_MSG_BUSY";
    case APP_MSG_BUFFER_OVERFLOW: return "APP_MSG_BUFFER_OVERFLOW";
    case APP_MSG_ALREADY_RELEASED: return "APP_MSG_ALREADY_RELEASED";
    case APP_MSG_CALLBACK_ALREADY_REGISTERED: return "APP_MSG_CALLBACK_ALREADY_REGISTERED";
    case APP_MSG_CALLBACK_NOT_REGISTERED: return "APP_MSG_CALLBACK_NOT_REGISTERED";
    case APP_MSG_OUT_OF_MEMORY: return "APP_MSG_OUT_OF_MEMORY";
    case APP_MSG_CLOSED: return "APP_MSG_CLOSED";
    case APP_MSG_INTERNAL_ERROR: return "APP_MSG_INTERNAL_ERROR";
    default: return "UNKNOWN ERROR";
  }
}

我使用该pebble analyze-size命令来测量内存影响。此功能将花费您额外的 228 字节程序存储器。对于大多数开发人员来说,这可能是值得的;)

这就是您使用上述函数的方式,例如在丢弃的消息处理程序中:

static void appmsg_in_dropped(AppMessageResult reason, void *context) {
   APP_LOG(APP_LOG_LEVEL_DEBUG, "In dropped: %i - %s", reason, translate_error(reason));
}
