我正在使用Android Studio 2.0 Preview 4。我正在使用Android SDK工具25 rc1。 无论我清理/重建项目多少次，此错误仍然存在。 File-> Invalidate Caches并重新启动也不起作用。我无法运行最基本的数据绑定示例。
build.gradle文件
apply plugin: ‘com.android.application’
android {
compileSdkVersion 23
buildToolsVersion “23.0.2”
defaultConfig {
applicationId “com.example.chiragshenoy.myapplication”

super.onCreate(savedInstanceState);
MainActivity binding = DataBindingUtil.setContentView(this, R.layout.activity_main);
User user = new User(“Test”, “User”);
binding.setUser(user);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}

这是我的顶级build.gradle文件
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath ‘com.android.tools.build:gradle:2.0.0-alpha3’
// 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
}
