我是android dev的新手。在Android Studio 2.2和Android版6.0中创建了一个应用程序。现在刚刚更新到android studio 2.3。它不适用于我的手机。

一个快速的建议是：你正在使用构建工具版本25，你的依赖项和编译器sdk正在使用版本24.你能检查一下是否解决了？
修改
您尝试访问无效索引中的位置列表，在尝试使用它之前，应验证它是否为有效索引。
答案 1 :(得分：0)
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
您应该更改类路径版本。
