我使用Android Studio 1.5.1版本
如果我创建新项目并且MainActivity扩展AppCompatActivity然后它不起作用它会产生如下错误：

我创建了新项目。不改变任何东西只运行它。但它给出错误。 我如何使用AppCompatActivity。
答案 0 :(得分：1)
你的logcat抛出
此应用程序的构建配置不正确。
您应该使用最新的 gradle plagin版本
classpath 'com.android.tools.build:gradle:2.2.2' //2.2.0
这是演示
dependencies {
classpath 'com.android.tools.build:gradle:2.2.2'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
<强> FYI
您可以在 build.gradle 部分添加此内容。
android {
defaultConfig {
vectorDrawables.useSupportLibrary = true
}
}
然后 Clean-Rebuild，Sync＆amp;运行
