android studio 新建项目报错的解决之路

android studio 新建工程报错

Error:Could not resolve all files for configuration ':app:debugCompileClasspath'.
> Could not resolve com.android.support:appcompat-v7:26.0.0-beta1.
  Required by:
      project :app
   > Could not resolve com.android.support:appcompat-v7:26.0.0-beta1.
      > Could not get resource 'https://dl.google.com/dl/android/maven2/com/android/support/appcompat-v7/26.0.0-beta1/appcompat-v7-26.0.0-beta1.pom'.

1、取消代理

Preferences->Appearance & Behavior->System Settings->Http Proxy
选择 No Proxy

2、取消隐藏代理

关掉隐形代理在mac 上对应的目录:~/.gradle/gradle.properties

3、
Preferences->Build,Execution,Deployment->Gradle,取消“offline work”的勾选,让studio去下载即可。

4、
Preferences->Build,Execution,Deployment->Gradle->Android Studio
取消勾选Disable embedded Maven Repository

5、修改project的bulid.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
 
 repositories {
 google()
 jcenter()
 }
 dependencies {
 classpath 'com.android.tools.build:gradle:3.0.1'
 

 // NOTE: Do not place your application dependencies here; they belong
 // in the individual module build.gradle files
 }
}

allprojects {
 repositories {
 google()
 jcenter()
 }
}
task clean(type: Delete) {
 delete rootProject.buildDir
}

在两个repository加了,阿里云的镜像

 maven {
 url 'http://maven.aliyun.com/nexus/content/groups/public/'
 }

再次sync,问题解决,但是把maven去掉,也能正常sync,有点迷,前几步,我的as本来就配好没有修改,猜测可能是wifi不好。。。

知识点补充:Android Studio 新建工程报错“”Error occurred during initialization of VM ..."解决办法

Android Studio 新建工程报错:

Error occurred during initialization of VM Could not reserve enough space for 1572864KB object heap

You encounter following error:

Error occurred during initialization of VM Could not reserve enough space for 1572864KB object heap

原因:Java虚拟机(JVM)没有足够的内存空间。

解决方案:

1:在个人文件夹( (C:/Users/username/.gradle 或 ~/.gradle))下创建gradle.properties文件,添加

org.gradle.jvmargs=-Xmx512m -XX:MaxPermSize=512m

2:或者直接在Android Studio中gradle.properties文件中添加下面这行,存在则修改

org.gradle.jvmargs=-Xmx512m -XX:MaxPermSize=512m
