Question

我在Intellij Idea中创建了一个Android项目（我使用的是Android Studio而不是Android Studio，因为我还需要在项目中管理一些React代码）。我创建了一个基本的Activity，它是构建项目的默认设置：

package com.example.mypackage.reacttoastex;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
}

但是，我在Intellij中收到此错误消息：

Gradle project sync failed. Basic functionality (e.g. editing, debugging) will not work properly

如果我运行Build Project，我会得到这个：

Error:A problem occurred configuring project ':app'.
> Could not resolve all dependencies for configuration ':app:_debugApkCopy'.
   > Could not find any version that matches com.android.support:appcompat-v7:27.+.
     Versions that do not match:
         26.0.0-alpha1
         25.3.1
         25.3.0
         25.2.0
         25.1.1
         + 31 more
     Required by:
         project :app

在日志中，我得到了这个：

这可能是什么原因？也许没有看到Android SDK？

Answer 1

今天这是一个类似的问题通过添加google maven repo解决了这个问题：

repositories {
    mavenLocal()
    mavenCentral()
    maven {
        url 'https://maven.google.com/' 
        name 'Google'
    }
}

虽然不是我的想法（我是Android开发的新手，而且只是熟悉Java），我在这里找到答案： https://stackoverflow.com/a/47165271/8036618

不确定原因是什么，但我在代理后面，所以也许IDEA无法从其默认仓库下载，但可以从google maven repo下载？
