openharmony体验

openharmony5 去年已经出来了
如果以前做过android开发的，学起来不难，关键
1：环境
DevEco Studio 5.0.3 Beta2 https://developer.huawei.com/consumer/cn/deveco-studio/
win10_64bit
CPU amd64(不是arm的)

2:安装
执行EXE 安装就行，网上一堆
API 自由选择
registry=https://repo.huaweicloud.com/repository/npm/
@ohos:registry=https://repo.harmonyos.com/npm/

创建模拟器
tools->device manger

随便创建个工程
修改 build-profile.json5 可以是在 entry目录下 增加 abiFilters x86_64 默认为 arm ,x86模拟器装不上
改成 “runtimeOS”: “OpenHarmony” 才是openharmony

{"apiType": 'stageMode',"buildOption": {"externalNativeOptions": {"abiFilters": ["arm64-v8a", "x86_64"],"path": "./src/main/cpp/CMakeLists.txt","arguments": "","cppFlags": "",}},"targets": [{"name": "default","runtimeOS": "HarmonyOS"},{"name": "ohosTest",}]
}

3：DEMO测试
直接来个native c++

出现下面的问题，就是要先把模拟器器开起来


自带 export const add: (a: number, b: number) => number;

import { hilog } from '@kit.PerformanceAnalysisKit';
import testNapi from 'libentry.so';
import StyleConstants from '../common/constants/StyleConstants';
import CommonConstants from '../common/constants/CommonConstants';const DOMAIN = 0x0000;@Entry
@Component
struct Index {@State message: string = 'Hello World';@State number1: number|string = '';@State number2: number|string = '';@State result:  string ="";build() {Row() {Column() {Text(this.message).fontSize($r('app.float.page_text_font_size')).fontWeight(FontWeight.Bold).onClick(() => {this.message = 'Welcome';hilog.info(DOMAIN, 'testTag', 'Test NAPI 2 + 3 = %{public}d', testNapi.add(2, 3));})TextInput({ placeholder: $r('app.string.inputnumber1') }).maxLength(StyleConstants.INPUT_ACCOUNT_LENGTH).type(InputType.Number).inputStyle().onChange((value: string) => {this.number1 = value;})TextInput({ placeholder: $r('app.string.inputnumber2') }).maxLength(StyleConstants.INPUT_ACCOUNT_LENGTH).type(InputType.Number).inputStyle().onChange((value: string) => {this.number2 = value;})Button($r('app.string.count')).id(CommonConstants.LOGIN_BUTTON_ID).width(StyleConstants.FULL_PARENT).height($r('app.float.login_button_height')).fontSize($r('app.float.normal_text_size')).fontWeight(FontWeight.Medium).backgroundColor($r('app.color.login_button_color')).margin({top: $r('app.float.login_button_top'),bottom: $r('app.float.login_button_bottom')}).onClick(() => {let num1 = 0,num2 =0;if(typeof this.number1 === 'string'){num1 = parseInt(this.number1);}else if (typeof this.number1 === 'number'){num1 = this.number1;}if(typeof this.number2 === 'string'){num2 = parseInt(this.number2);}else if (typeof this.number2 === 'number'){num2 = this.number2;}this.result = testNapi.add(num1,num2).toString(10);})Text(this.result).fontColor($r('app.color.blue_text_color')).fontSize($r('app.float.normal_text_size')).fontWeight(FontWeight.Medium)}.width('100%')}.height('100%')}
}@Extend(TextInput) function inputStyle() {.placeholderColor($r('app.color.placeholder_color')).height($r('app.float.login_input_height')).fontSize($r('app.float.normal_text_size')).backgroundColor(Color.White).margin({ top: $r('app.float.input_margin_top') }).padding({ left: StyleConstants.INPUT_PADDING_LEFT })
}@Extend(Text) function blueTextStyle() {.fontColor($r('app.color.blue_text_color')).fontSize($r('app.float.small_text_size')).fontWeight(FontWeight.Medium)
}

当前API 为15 跑14的模拟器，跑不起来

需要调下API 为14

APP name

4: 没有开发版，支持 openharmony5 开发版都不便宜，1500+起，
HarmonyOS 才能用模拟器，测试用不起，这狗屎的生态，
