Android 项目运行和打包报错
Read timed out

如果使用了代理，关闭代理，改成国内镜像
项目根目录的 build.gradle 对应地方加上这三行镜像地址就行了

buildscript {
repositories {
maven { url 'https://maven.aliyun.com/repository/google' }
maven { url 'https://maven.aliyun.com/repository/jcenter' }
maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }

}
}

allprojects {
repositories {
maven { url 'https://maven.aliyun.com/repository/google' }
maven { url 'https://maven.aliyun.com/repository/jcenter' }
maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }
}
}
