导入项目时进度条卡住不动

查看gradle版本：

C:\Users\用户名\.gradle\wrapper\dists\gradle-1.XX-all

存放位置：

C:\Users\用户名\.gradle\wrapper\dists\gradle-1.XX-all\3jdgemv0iv8uqohg3kcp2o88r1\gradle-1.XX-all.zip

手工下载gradle
https://downloads.gradle.org/distributions/gradle-2.2.1-all.zip
https://downloads.gradle.org/distributions/gradle-2.4-all.zip

放到对应位置
C:\Users\king.gradle\wrapper\dists\gradle-x.x.x-all\c64ydeuardnfqctvr1gm30w53
重启android studio ，自动解压。

或者单击：
android studio工具栏 => Sync Project Gradle Files

另外网上有一种处理方式，我没有测试：

java.lang.UnsupportedClassVersionError: com/android/dx/command/Main : Unsupported major.minor version 52.0

修改build.gradle Module:app
把

android {    compileSdkVersion 23    buildToolsVersion "24.0.0"

改为

android {    compileSdkVersion 23    buildToolsVersion "23.0.0"

或者在这里修改：

Android Studio菜单异常，不能正常新建Project

删除 C:\Users\用户名.AndroidStudio1.5
其中.AndroidStudio1.5可能不是这个名字。

修改：build.gradle

 defaultConfig {        multiDexEnabled true   加这一句        versionCode cdvVersionCode ?: Integer.parseInt("" + privateHelpers.extractIntFromManifest("versionCode") + "0")        applicationId privateHelpers.extractStringFromManifest("package")        if (cdvMinSdkVersion != null) {            minSdkVersion cdvMinSdkVersion        }    }

buildToolsVersion ‘23.0.3’

minSdkVersion 错误

把Settings-Build、Execution、Deployment-Gradle 下的Offline work的钩去掉，重启Android Studio
