Android Studio - 错误：程序类型已经存在 [英] Android Studio - Error:Program type already present

问题描述

当我尝试编译代码时，Android Studio 3.0.1上出现以下错误：

When I try to compile the code, the following error appears on Android Studio 3.0.1

Error:Program type already present: com.squareup.picasso.Action$RequestWeakReference

我的gradle代码：

My gradle code:

  ...
    compile 'com.android.support:appcompat-v7:26.1.0'
    compile 'com.android.support:design:26.1.0'
    compile 'com.android.support:support-v4:26.1.0'
    compile 'com.android.support:support-vector-drawable:26.1.0'
    compile 'com.android.support.constraint:constraint-layout:1.1.0-beta4'
    compile 'com.google.firebase:firebase-messaging:11.8.0'
    compile 'com.google.firebase:firebase-ads:11.8.0'
    compile 'com.google.gms:google-services:3.1.0'
    compile 'com.google.android.gms:play-services:11.8.0'
    compile 'com.squareup.picasso:picasso:2.5.2'
    testCompile 'junit:junit:4.12'

}

apply plugin: 'com.google.gms.google-services'

我如何修复我的gradle脚本来修复错误？

How do I fix my gradle script to fix the error?

推荐答案

检查应用程序设置中的编译版本。我将其更改为与我用我的项目构建的API级别兼容的版本。
这解决了我的问题。

Check the compile version in your App settings. I changed it to the version compatible with the API level I've built my project with. This fixed the problem for me.
