如何将鸿蒙5应用升级到鸿蒙6
设置targetSdkVersion
点第二项。
build-profile.json5改为了如下：
{
"app": {
"signingConfigs": \[\],
"products": [
{
"name": "default",
"signingConfig": "default",
"compatibleSdkVersion": "5.0.0(12)",
"runtimeOS": "HarmonyOS",
"buildOption": {
"strictMode": {
"caseSensitiveCheck": true
}
},
"targetSdkVersion": "6.0.0(20)"
}
],
"buildModeSet": [
{
"name": "debug",
},
{
"name": "release"
}
]
},
"modules": [
{
"name": "entry",
"srcPath": "./entry",
"targets": [
{
"name": "default",
"applyToProducts": [
"default"
]
}
]
}
]
}
升级modelVersion
点击Migrate Assistant，会自动做如下更改：
To start migration, select the version to which you want to migrate this project (in both hvigor and ohpm) and click Migrate.
This migration will lead to the following changes:
-
Upgrade hvigor modelVersion from 5.0.0 to 6.0.0
-
Upgrade ohpm modelVersion from 5.0.0 to 6.0.0
点击Migrate
oh-package.json5会自动改为了如下：
{
"modelVersion": "6.0.0",
"description": "Please describe the basic information.",
"dependencies": {
},
"devDependencies": {
"@ohos/hypium": "1.0.19",
"@ohos/hamock": "1.0.0"
}
}
代码整改
查看编译情况，关注控制台日志。如果有报错，根据提示进行整改。
常见的问题是，鸿蒙6的ArkTS语言语法规则更加严格，
因此，需要做一些判空处理或者是类型指定等。
