Android Studio 3.1.4:不支持 java.time.LocalDate"
Android Studio 3.1.4: java.time.LocalDate" is not supported
Android Studio 3.1.4,Java 8,Gradle 4.4.
在我的 build.gradle:
compileSdkVersion 26
minSdkVersion 18
targetSdkVersion 26
compileOptions {
targetCompatibility JavaVersion.VERSION_1_8
sourceCompatibility JavaVersion.VERSION_1_8
}
implementation 'com.android.support:appcompat-v7:26.1.0'
在我的 POJO 中
import java.time.LocalDate;
import java.util.Date;
public class Product {
private Date redeemed_date;
private LocalDate myLocalDate;
}
我必须使用 minSdkVersion 18
因为这是客户要求。
但是构建时出现错误:
error: Field "myLocalDate" of type "java.time.LocalDate" is not supported.
The JavaDocs for LocalDate
显示它是在 API 级别 26 中添加的。您的 minSdkVersion
低于该级别,因此 LocalDate
将不会在所有设备上受支持你想 运行 on.
您的选择是:
将您的 minSdkVersion
提高到 26,或者
用别的东西,比如ThreeTenABP, that
自 2020 年 4 月起,使用 Android Gradle 插件 4.0.0,您可以启用对 Java 8 种语言的支持API(查看所有支持的 API:https://developer.android.com/studio/write/java8-support-table)
To enable support for these language APIs on any version of the
Android platform, update the Android plugin to 4.0.0 (or higher) and
include the following in your module’s build.gradle file:
android {
defaultConfig {
// Required when setting minSdkVersion to 20 or lower
multiDexEnabled true
}
compileOptions {
// Flag to enable support for the new language APIs
coreLibraryDesugaringEnabled true
// Sets Java compatibility to Java 8
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
dependencies {
coreLibraryDesugaring 'com.android.tools:desugar_jdk_libs:1.0.9'
}
