1. Create a new project

When developing a HarmonyOS When applied , First, you need to create a wizard according to the project , Create a new project , The tool will automatically generate the corresponding code and resource template .

1. Create and configure new projects

First , Open the project creation wizard interface in the following two ways .

• If no project is currently open , Can be in DevEco Studio Welcome page selection Create HarmonyOS Project Start creating a new project .
• If the project has been opened , You can choose... From the menu bar File–>New–>New Project To create a new project .

next , Select the equipment type to be developed according to the project creation wizard , Then choose the corresponding Ability Templates , As shown in the figure below ：

single click Next Button , Enter the engineering configuration stage , Basic information of configuration project ：

• Project name： The name of the project , You can customize .（ Head nomenclature ）
• Project type： The type of work , Mark that the project is a Atomic Services （Atomic Service） Or traditional installation application （Application）.
• Bundle name： Package name , By default , application / service ID This name will also be used , application / When the service is released , application / service ID Need to be the only . If “Project Type” I chose Atomic Service, be Bundle Name The suffix of must be .hmservice.
• Save location： Local storage path of project files , Please note that , The project storage path cannot contain Chinese characters .
• Development mode： Select the development mode , Some templates support Low code development , Can choose Super Visual.
• Language： The development language supported by the project template , You can choose according to the language supported by the template JS or eTS or Java, among eTS stay DeEco Studio V3.0 Beta2 And above support .
• Compatible API version： Compatible SDK Minimum version .
• Device type： The equipment types supported by this project template , Support multiple choices , Check all by default . If multiple devices are checked , It means that the atomic service or traditional application that needs to be installed supports deployment on multiple devices .
• Show in service center： Whether it is exposed in the service center . If Project type by Atomic Service, A... Will be created synchronously 2 * 2 Service card template , At the same time, an entry card will be created ; If Project type by Application, Will only create one 2*2 Service card template .
• Use ArkCompiler： Turn on the switch , Indicates that the project is compiled and built , Use ArkCompiler The ark compiler compiles .

single click Finish Button , The tool automatically generates sample code and related resources , Wait for the project to be created .

2. Create a local virtual machine

DevEco Studio Provided Local Emulator be based on X86 framework , Can run and debug Phone、TV and Wearable The equipment HarmonyOS application / service . stay Local Emulator Run applications on / Services are compatible with signing and non signing HAP.

​ Local Emulator Compared with Remote Emulator,Local Emulator yes Create and run on the local computer Of , No login authorization is required , In running and debugging applications / The service , Because there is no exchange of network data , Therefore, it can maintain good fluency and stability ; however It requires a certain amount of computer disk resources .

Create and run Local Emulator Operation steps of

1. Click on Files > Settings > SDK Manager > HarmonyOS Legacy SDK Tab , Check and download Platforms Under the System-image and Tools Under the EmulatorX86 resources .

You can see System-image Include phone,tv,wearable, Corresponding to mobile phones respectively , TV and wearable devices ; I c Only download if the disk is limited phone resources , Demonstrate local phone virtual machine

choice Phone, Then click Install request component library

installation is complete

stay Local Emulator In the TAB. , Click on the New Emulator Button , Create a local simulator . By default , The created local simulator resources will be stored in C:\Users\ user name \AppData\Local\Huawei\HarmonyOSEmulator\deployed Under the table of contents , It will occupy a large system storage space .

In the create simulator interface , You can choose a default device ; You can also click New Hardware Or the clone icon behind the default device , Add a new device , In order to customize the relevant parameters of the device , As size 、 The resolution of the 、 Memory and other parameters . Customize new devices , Currently only supported Phone equipment ,TV and Wearable Temporary does not support . establish New Hardware when , You can modify the name of the device 、 Size 、 The resolution of the 、 Memory and other parameters .

Click on Next, Verify and determine the simulator information that needs to be created , At the same time, you can also modify the simulator information in this interface , And then click Finish Create a local Simulator .

3. Use remote virtual machines （ recommend ）

Remote Emulator Support Wearable、Tablet、TV And so on , But different areas （ Where the developer account is registered ） The supported device types may be different , Please refer to the type of equipment that can be applied for .

3.1 Single terminal

​ Remote Emulator The single device simulator in can run and debug Phone（ Folding screen Mate X2、P40 and P40 Pro）、Tablet（MatePad Pro）、TV and Wearable The equipment HarmonyOS application / service , Compatible with signature and non signature HAP.

​ Remote Emulator The duration of each use is 1 Hours , Resources will be released automatically after expiration , Please complete it in time HarmonyOS application / Service debugging . If Remote Emulator After expiration and release , You can reapply for resources （ Login again ）.

The specific steps are as follows ：

1. stay DevEco Studio menu bar , Click on Tools > Device Manager.
2. stay Remote Emulator In the TAB. , Click on Login, The login interface of Huawei developer alliance account pops up in the browser , Please enter the user name and password of the Huawei developer alliance account with real name authentication to log in （ Check the remote emulator login FAQ ）.
3. After logging in , Please click the allow button on the interface to authorize , After successful authorization DevEco Studio The confirm authorization window will appear , Click on Agree that will do .

After login, you can see DevEco Created for us 6 Virtual machines , stay Single device in , Click the device operation button , Start the remote simulation device （ Only one device can be started at a time ）.

Then you can experience it for free for an hour P40, Hee hee , Lightly brush Tiktok , Although it's a little stuck .

3.2 hyper terminal

​ At present, HyperTerminal simulator supports “Phone+Phone”、“Phone+Tablet” and “Phone+TV” Device networking mode , Developers can use the HyperTerminal simulator to test applications with cross device characteristics / service , Such as application / The circulation of services between different devices .

The specific steps are as follows ：

1. stay DevEco Studio menu bar , Click on Tools > Device Manager.

2. stay Remote Emulator In the TAB. , Click on Login. The login interface of Huawei developer alliance account pops up in the browser , Please enter the user name and password of the Huawei developer alliance account with real name authentication to log in . If you are already logged in , You can jump directly to the 4） Step .

3. After logging in , Please click the allow button on the interface to authorize .
