A hidden Kotlin gem: Deprecations with ReplaceWith

如果@Deprecated加上replaceWith:

@Deprecated(
    message = "Use simpler logout() instead",
    replaceWith = ReplaceWith("logout()")
)
fun doLogout() {
    logout()
}

点击Alt + Enter就可以自动替换成建议的方法.

还可以有参数和加import:

@Deprecated(
    message = "Use simpler login with Credentials",
    replaceWith = ReplaceWith(
        expression = "login(Credentials(usr, pwd))",
        imports = ["auth.Credentials"]
    )
)
fun doLogin(pwd: String, usr: String) {
}

@Deprecated默认的等级是warning, 其实还有error和hidden.

Android Studio 4.0

几个比较重要的改变:

• motion layout的编辑器
• Smart editor feature when writing rules for R8
• 项目配置:

android {
    // The default value for each feature is shown below.
    // You can change the value to override the default behavior.
    buildFeatures {
        // Determines whether to support View Binding.
        // Note that the viewBinding.enabled property is now deprecated.
        viewBinding = false
        // Determines whether to support Data Binding.
        // Note that the dataBinding.enabled property is now deprecated.
        dataBinding = false
        ...
    }
}
