下面是我的 build.gradle(app level)

   dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:+'
    compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha3'

    compile 'com.ahmedjazzar.rosetta:rosetta:1.0.1'
}

我尝试了 stackoverflow 的不同解决方案，但没有一个有效。请你帮我解决这个问题。提前致谢。

最佳答案

I already answered a similar question here.

尝试将 compileSdkVersion 更改为:

compileSdkVersion 28

这些属性是在这个版本中添加的。查看 here , here和 here
