上一次SDK更新后，Android Studio无法找到任何Google Play服务或Firebase库

Question

我有一个正在运行的项目，但昨天我更新了android sdk和sdk工具。

突然之间

Failed to resolve: com.google.android.gms:play-services-maps:10.2.0
Failed to resolve: com.google.firebase:firebase-messaging:10.2.0
Failed to resolve: com.google.firebase:firebase-core:10.2.0

这发生在我所有的Android项目中！

即使在离子项目中也能正常工作，现在它使我Could not find gradle wrapper within Android SDK. Might need to update your Android SDK. Could not find gradle wrapper within Android SDK. Might need to update your Android SDK.

在对Android Studio 2.3或API 25r3的更新中进行了任何更改吗？

如果我转到模块设置>依赖项，并尝试从choose library dependency窗口中添加这些库，则找不到它们：

我的SDK工具：

由于该项目已经在工作，所以我已经正确配置了所有内容。

有人有同样的问题吗？

Answer 1

解决方案通过从SDK管理器中删除google repository并重新安装来解决。

Answer 2

在您的终端

nano ~/.bash_profile 

添加行：

export ANDROID_HOME=/YOUR_PATH_TO/android-sdk
export PATH=$ANDROID_HOME/platform-tools:$PATH
export PATH=$ANDROID_HOME/tools:$PATH
