Android AS问题：Error:Failed to complete Gradle execution. Cause: Write access is allowed from event d

1、Error:Failed to complete Gradle execution.

     Cause:

     Write access is allowed from event dispatch thread only

重新选择Android SDK 位置，

步骤如下：

File -> Project Structure -> SDK Location 

【勾选Use embedded JDK，点击OK，就可以了】

2、error: style attribute '@android:attr/windowEnterAnimation' not found.

解决方法：

在Project/gradle.properties中添加 android.enableAapt2=false

3、Error:Execution failed for task ':app:javaPreCompileDebug'.
 > Annotation processors must be explicitly declared now.  The following dependencies on the compile classpath are  found to contain annotation processor.  Please add them to the annotationProcessor configuration.
    - butterknife-6.0.0.jar (com.jakewharton:butterknife:6.0.0)
  Alternatively, set android.defaultConfig.javaCompileOptions.annotationProcessorOptions.includeCompileClasspath = true to continue with previous behavior.  Note that this option is deprecated and will be removed in the future.

  See https://developer.android.com/r/tools/annotation-processor-error-message.html for more details.


解决方法：
在app的build   defaultConfig中 配置 javaCompileOptions

android {

    ...
    defaultConfig {
        ...
        //添加如下配置就OK了
        javaCompileOptions { annotationProcessorOptions { includeCompileClasspath = true } }
    }
    ...
}
