从 Android Studio 2.3.3 更新到 3.0 导入我的项目并收到此错误：

Program type already present: com.google.firebase.iid.zzd

apply plugin: 'com.android.application'




    //Optionally configure your OneSignal IDs below
    manifestPlaceholders = [manifestApplicationId: "${applicationId}",
                            onesignal_app_id: "",
                            onesignal_google_project_number: ""]

很快就找到了问题的解决方案。我必须将我的 $gps_version 更新到最新版本，项目工作正常，错误消失了

compile "com.google.android.gms:play-services-gcm:$gps_version"
compile "com.google.android.gms:play-services-ads:$gps_version"
compile "com.google.android.gms:play-services-maps:$gps_version"
