我将我的android工作室更新到版本3.0,我在以前版本的工作室中使用jackOption
。更新后出现此警告。我收到了这个警告。但我不知道在哪里添加这两行建议?
Warning:The Jack toolchain is deprecated and will not run. To enable support for Java 8 language features built into the plugin, remove 'jackOptions { ... }' from your build.gradle file, and add
android.compileOptions.sourceCompatibility 1.8
android.compileOptions.targetCompatibility 1.8
Future versions of the plugin will not support usage of 'jackOptions' in build.gradle.

答案 0 :(得分:11)
步骤1:打开build.gradle
(模块应用)
步骤2:在android
块下添加以下行
android {
//.. other code
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
第3步:同步项目或点击sync now
(显示在右上角)
注意:如果jackOptions
(模块)中有build.gradle
defaultConfig {
jackOptions {
enabled true
}
}
然后删除jackOptions Block
您也可以通过选择
来完成 File -> Project structure
选择app->Properties
并选择java 8作为兼容性
