C:\Users\aa.AndroidStudio3.2\config\options\jdk.table.xml

原文件内容如下:

<jdk version="2">
  <name value="Android API 23 Platform" />
  <type value="Android SDK" />
  <version value="java version &quot;1.8.0_152&quot;" />
  <homePath value="D:\programtools\newas\sdk" />
  <roots>
    <annotationsPath>
      <root type="composite">
        <root url="jar://$APPLICATION_HOME_DIR$/plugins/android/lib/androidAnnotations.jar!/" type="simple" />
      </root>
    </annotationsPath>
    <classPath>
      <root type="composite">
        <root url="jar://D:/programtools/newas/sdk/platforms/android-23/android.jar!/" type="simple" />
        <root url="file://D:/programtools/newas/sdk/platforms/android-23/data/res" type="simple" />
      </root>
    </classPath>
    <javadocPath>
      <root type="composite">
        <root url="file://D:/programtools/newas/sdk/docs/reference" type="simple" />
      </root>
    </javadocPath>
    <sourcePath>
      <root type="composite">
        <root url="file://D:/programtools/newas/sdk/sources/android-23" type="simple" />
      </root>
    </sourcePath>
  </roots>
  <additional jdk="1.8" />
</jdk>

<jdk version="2">
  <name value="Android API 27 Platform (1)" />
  <type value="Android SDK" />
  <version value="java version &quot;1.8.0_152&quot;" />
  <homePath value="D:\programtools\newas\sdk" />
  <roots>
    <annotationsPath>
      <root type="composite">
        <root url="jar://$APPLICATION_HOME_DIR$/plugins/android/lib/androidAnnotations.jar!/" type="simple" />
      </root>
    </annotationsPath>
    <classPath>
      <root type="composite">
        <root url="jar://D:/programtools/newas/sdk/platforms/android-27/android.jar!/" type="simple" />
        <root url="file://D:/programtools/newas/sdk/platforms/android-27/data/res" type="simple" />

        <root url="file://D:/programtools/newas/sdk/docs/reference" type="simple" />
      </root>
    </javadocPath>
    <sourcePath>
      <root type="composite">
        <root url="file://D:/programtools/newas/sdk/sources/android-27" type="simple" />
      </root>
    </sourcePath>
  </roots>
  <additional jdk="1.8 (1)" sdk="android-27" />
