JDK 1.7未显示在Program Files文件夹中

[英]JDK 1.7 not shown in Program Files folder

原文 2014-11-21 08:42:46 7 3 java/ android/ android-studio

I have started developing an Android application in Android Studio. 我已经开始在Android Studio中开发Android应用程序。 After starting Android Studio it gives me an error: "compileSdkVersion android-21 requires compiling with JDK 7". 启动Android Studio后，它给我一个错误：“ compileSdkVersion android-21要求使用JDK 7进行编译”。 So I ran java -version at the Commmand Prompt and it shows I have 1.7. 所以我在Commpand Prompt上运行了java -version ，它显示我有1.7。 But in Program Files there is a folder for JDK 1.6 but not for 1.7. 但是在“程序文件”中，有一个用于JDK 1.6的文件夹，而不是用于1.7的文件夹。 JRE of 1.7 is there, but not JDK 1.7. 有1.7的JRE，但没有JDK 1.7。

Any suggestions will be appreciated. 任何建议将不胜感激。 Thanks in advance. 提前致谢。

Try "javac -version" instead of "java -version" to confirm JDK installed version 尝试使用“ javac -version”而不是“ java -version”来确认JDK的安装版本

It seems that you have a 1.7 Java Runtime but only 1.6 SDK installed. 看来您安装了1.7 Java Runtime，但仅安装了1.6 SDK。

Just get the correct SDK installer from java.com. 只需从java.com获得正确的SDK安装程序。
