Before you start your application development, complete the following preparations.
Register as a developer on HUAWEI Developers and complete identity verification to enjoy the open capabilities and services provided by HUAWEI Developers.
Create a HarmonyOS app in AppGallery Connect (AGC) by referring to Creating a Project and Creating a HarmonyOS App.
Install the latest version of DevEco Studio. For details about the installation, see Downloading and Installing DevEco Studio.
Create an application project on DevEco Studio. For details about how to create a project, see Creating a Project.
You do not need to configure the signing information when using the Emulator or Previewer for debugging. If you use a real device for debugging, you must sign the HAP.
Currently, two signing modes are available:
Automatic signing: If you only need to use one debugging device, you are advised to use the automatic signing function provided by DevEco Studio.
Manual signing: If you use multiple debugging devices or debug your app when the network is disconnected, you need to apply for a debug certificate, register debugging devices, and apply for a debug profile in AppGallery Connect, and then manually configure signing information.
If your application needs to use one or more of the following open capabilities, you need to add a public key fingerprint in advance to debug and run the application:
Account Kit
Game Service Kit
Health Service Kit
IAP Kit
Payment Kit
Wallet Kit
Wear Engine Kit
Before releasing the application, switch the application's debug fingerprint to its release signature.
Add the public key fingerprint. For details, see Configuring a Public Key Fingerprint.
