1. 无法从网络获取 gradle-3.6.0.pom 文件

问题描述

具体表现为 Sync Project with gradle file 之后报错：

具体报错信息为：

FAILURE: Build failed with an exception.* What went wrong:A problem occurred configuring root project 'My Application'.> Could not resolve all artifacts for configuration ':classpath'.   > Could not resolve com.android.tools.build:gradle:3.6.0.

解决办法

可以看出主要是无法从https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/3.6.0/gradle-3.6.0.pom获得资源文件。
我们可以改变AndroidStudio的默认配置，不用https。
具体打开 C:\Users\用户名\.gradle\gradle.properties文件

systemProp.http.proxyHost=fodev.orgsystemProp.https.proxyPort=8118systemProp.https.proxyHost=fodev.orgsystemProp.http.proxyPort=8118

注释掉其中 https 的两项。即改为：

systemProp.http.proxyHost=fodev.org# systemProp.https.proxyPort=8118# systemProp.https.proxyHost=fodev.orgsystemProp.http.proxyPort=8118

保存之后重新点击AndroidStudio的File -> Sync Project with gradle file即可。

2. Android Studio设计编辑器不显示

问题描述

Android studio design editor is unavailable until after a successful project sync

点击AndroidStudio的File -> Sync Project with gradle file 之后发现报错：

解决办法

修改项目的Module.app的build.gradle文件，注释掉测试的依赖包

dependencies {    implementation fileTree(dir: "libs", include: ["*.jar"])    implementation 'androidx.appcompat:appcompat:1.1.0'    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'//    testImplementation 'junit:junit:4.12'//    androidTestImplementation 'androidx.test.ext:junit:1.1.1'//    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'}
