概述
OpenHarmony的主干代码是开源社区的重要学习资源,对于想进行应用开发和熟悉OpenHarmony能力的同学主干代码是非常重要的资源,在主干代码的applications目录里聚集了很多原生的应用实现,那么如何编译这些代码就是我们这篇文章的主要议题。
使用DevEco导入编译
导入代码
自动下载npm包
导入应用后,IDE工具就会自动sync相关依赖npm包,完成之后会出现以下界面。
然后即可以开始build
一些报错处理
sdk依赖缺失:
ETS:ERROR File: D:/gitee/applications_app_samples-master/settings1118/settings/settings/product/phone/src/main/ets/model/wifiImpl/WifiModel.ts:386:20
Property 'removeDevice' does not exist on type 'typeof wifi'.
ETS:ERROR File: D:/gitee/applications_app_samples-master/settings1118/settings/settings/product/phone/src/main/ets/model/wifiImpl/WifiModel.ts:391:37
Property 'getDeviceConfigs' does not exist on type 'typeof wifi'.
ETS:ERROR File: D:/gitee/applications_app_samples-master/settings1118/settings/settings/product/phone/src/main/ets/model/wifiImpl/WifiModel.ts:395:24
Property 'connectToDevice' does not exist on type 'typeof wifi'.
ETS:ERROR File: D:/gitee/applications_app_samples-master/settings1118/settings/settings/product/phone/src/main/ets/model/wifiImpl/WifiModel.ts:439:41
Property 'getDeviceConfigs' does not exist on type 'typeof wifi'.
以上错误即为sdk缺失导致,也就是import wifi from ‘@ohos.wifi’;这个d.ts文件里没有和主干最新的接口和功能同步,这时候偷懒的法子就是在对应的文件头增加// @ts-nocheck,如下。如果是正规方式,则应该找主干代码里的对应文件,拷贝到IDE的sdk目录下。
// @ts-nocheck
import LogUtil from '../../../../../../../common/utils/src/main/ets/default/baseUtil/LogUtil';
import ConfigData from '../../../../../../../common/utils/src/main/ets/default/baseUtil/ConfigData';
import wifi from '@ohos.wifi';
import BaseModel from '../../../../../../../common/utils/src/main/ets/default/model/BaseModel';
按以上套路能编译出来,提示信息如下:
> hvigor Finished :phone:CompileResources... after 602 ms
> hvigor WARN: ETS:WARN File: D:\gitee\applications_app_samples-master\settings1118\settings\settings\product\phone\src\main\ets\pages\volumeControl.ets
It's not a recommended way to export struct with @Entry decorator, which may cause ACE Engine error in component preview mode.

hap包没有签名:
按以上套路编出来的,会发现没有签名的hap包。如图:
这时候应该走File -> Project Structure -> Signing Configs -> automatically generate signature,如果有选中需要取消选中然后再选中,然后apply,最后OK。
但是这时候其实还没有显示出来,其实上面的报错也有显示,即:
```bash
> hvigor WARN: Will skip sign 'hap'. Invalid signingConfig is configured for 'default' product.
```
这是因为命名不匹配,需要修改build-profile.json5文件的signingConfig:
```bash
"signingConfig": "release" 改成 "signingConfig": "default"
```
这样应该就能编译出signed.hap这应用程序包了
install的权限问题:
如果在安装的时候发现install的权限报错,则是很有可能是权限配置问题。OpenHarmony的应用分一般应用和系统应用,系统自带的applications大多是系统自带应用,所以配置IDE工具sdk里的UnsgnedReleasedProfileTemplate.json,具体位置在:sdk\toolchains\3.2.7.5(对应下载和使用的sdk版本)\lib。在这个文件里,我们需要修改以下位置:
{
"version-name": "2.0.0",
"version-code": 2,
"app-distribution-type": "os_integration",
"uuid": "5027b99e-5f9e-465d-9508-a9e0134ffe18",
"validity": {
"not-before": 1594865258,
"not-after": 1689473258
},
"type": "release",
"bundle-info": {
"developer-id": "OpenHarmony",
"distribution-certificate": "-----BEGIN CERTIFICATE-----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\nL5RlJ/m5o13Q\n-----END CERTIFICATE-----\n",
"bundle-name": "com.ohos.settings",
//需要修改的系统应用权限
"apl": "system_core",
"app-feature": "hos_normal_app"
},
"acls": {
//需要增加的权限,根据hap的权限申请设置
"allowed-acls": [
"ohos.permission.CAPTURE_SCREEN",
"ohos.permission.MANAGE_USER_IDM"
]
},
"permissions": {
"restricted-permissions": []
},
"issuer": "pki_internal"
}
这样一般就可以安装了。
Install的包名问题:
我们OpenHarmony主干拷贝出来的application的包名一定会和板子上运行的原程序同名的,这样安装时也会提示报错,这种时候,我们需要修改"bundleName": “com.ohos.settings”, 以及sign文件里的对应的名字。大概是两个文件:
product\phone\build\default\intermediates\merge_profile\default\module.json。
"bundleName": "com.ohos.settings", //改成新名字如newsetting
build-profile.json5。
"signingConfigs": [
{
"name": "default",
"material": {
"certpath": "C:\\Users\\Administrator\\.ohos\\config\\openharmony\\auto_ohos_default_com.ohos.settings.cer", //使用上面新名字替换com.ohos.settings
"storePassword": "0000001BC6E86D64AD786A77BBF86702F23E6DD32E016E263D961DBCD4710340CD6EAC6B2A4A43A53DDFA0",
"keyAlias": "debugKey",
"keyPassword": "0000001B9CB15173695726ED3460368DEEC246A602353461BBD9321C77513130E462B2BEB9F39DB201E92A",
"profile": "C:\\Users\\Administrator\\.ohos\\config\\openharmony\\auto_ohos_default_com.ohos.settings.p7b",
"signAlg": "SHA256withECDSA",
"storeFile": "C:\\Users\\Administrator\\.ohos\\config\\openharmony\\auto_ohos_default_com.ohos.settings.p12"
}
}
]
小结
通过上述方式,我们就能编译并安装运行OpenHarmony自带的应用并学习基础能力的开发了。
