If you have Xiaomi Smart Band 7, you can find unofficial apps and watch faces for your device. But, what is required to create your own one? This post describes what do you need to know to create app or watch face from scratch.
Any ZeppOS app / watch face
.bin-file is a ZIP archive, which contains graphics and code. You can rename it and unpack, but images inside
assets directory have their own TGA-based format, and to open them you should convert them back to PNG with some tool that can do it.
But, our device isn’t supported in ZeppOS development toolchain, their simulator and builder aren’t usable for us. So we have some homebrew alternatives:
- ZeppPlayer – a emulator that can run apps or watch faces on PC;
- ZMake – builder, which can convert graphics into ZeppOS format. As alternative you can use tools from Chinese community.
In some apps or watch faces you can find
.bin files instead of
.js code. That scripts are compiled into bytecode, so you can’t read it. For now, there’s no way to reverse them.
Where to find more information?
