讨论 Band 9 从互联网 (http) 加载图像的简单应用程序

[yaiko]

嗨
我正在尝试使用本机框架开发一个基本应用程序：https://iot.mi.com/vela/quickapp/

一切都运行良好，应用程序可以加载到我的智能手环中，但是当我尝试使用需要互联网连接的功能时似乎不起作用，我试图从互联网上获取 <image/> 但它没有加载，我也尝试使用 @system.fetch 从 https API 加载数据，但都不起作用。
（尽管它只在模拟器 IDE 中有效）

有人知道如何做到这一点吗？
或者是否有其他方法可以将图像从 Android 设备下载并移动到应用程序资产？我只是试图从互联网上渲染图像。

我对这个框架很陌生，希望有人能帮助我，谢谢！
（我使用了谷歌翻译，对不起我的中文）

Hi
I'm trying to develop a basic app with the native framework: https://iot.mi.com/vela/quickapp/

Everything worked well and the app loads in my smart band, however when I try to use functions that require internet connection seems to not work, I'm trying to fetch an <image/> from internet but it doesn't load, I also tried loading data from a https API with @system.fetch but doesn't work neither.
(Despite it works only in the emulator IDE)

Is there somebody that knows how to make this work?
Or if also there is an alternative to download and move the image from the Android device to the app assets?, I'm simply trying to render an image from internet.

I'm new with this framework, hope somebody can help me out, thanks!
(I used google translator, sorry for my chinnese)

我尝试使用 system.interconnect 演示但似乎不起作用
有人可以确认这是否在 MI Band 9 中不起作用吗？谢谢

I've tried using the system.interconnect demo but seems to not work
Could somebody confirm if this doesn't work neither in MI Band 9? Thanks

The main problem is band9 doesn't support @system.fetch, so you can't use it, and access internet on your band directly (such as load online image).

As for system.interconnect, it is an API that allows a band and an Android app to communicate in a socket-like communication, and Band 9 supports it. This means you need to develop a dedicated Android app for transmitting images. When your band needs to load an online image, it should send a request to your Android app via interconnect. The Android app will then download the required online image, encode it into something like Base64, and transmit it back to your band. Once the band receives it, it needs to decode and save the image before displaying it. This is merely a feasible idea—everything needs to be implemented by yourself, and there are no official examples available.

I understand that, but according to their protocol the interconnection in the app is done via their Wearable SDK (They have an official example in the last link of the docs) which supposedly works together with the Wearable App but it doesn't interconnect for me.

I tried this app that does something similar to what I'm trying to do and it also requires the Wearable app for the interconnection but for some reason it can't interconnect neither 🙁
