Want to go through the Mini Program hardware framework (WMPF) To run the mini program on the device, you need to connect the hardware device to the device system of WeChat, and register the corresponding mobile application and mini program.Device - Application - Mini ProgramAssociation between. Before starting development, the following needs to be prepared:

1. registeredWeChat terminal cooperation platformaccount(An account can be accessed directly.) Once approved, you can downloadFast Experience Demo, Early Access Mini Program Effects on Running Devices
2. registeredWeChat Open PlatformAccount number (existing account can be directly logged in), andCreating a Mobile App(You can also use existing apps)

After completing all the above steps, your device is really connected to the WeChat device system, and then you can check theDevelopment GuideTo carry out WMPF Client Of the code development.

Please note that developers distinguishMobile applicationandMini ProgramThe difference:

• Mobile applicationandMini ProgramIt is two sets of account systems under the WeChat ecosystem, each mobile application and Mini Program has a appId As a unique identifier.
• Mobile application Appid (commonly referred to as hostAppId） It was inWeChat Open PlatformThe application is obtained to identify a native application developed by the developer.
