命令行使用avdmanager的时候报Unsupported major.minor version 52.0是怎么回事啊

Question

java version "1.7.0_121"
OpenJDK Runtime Environment (IcedTea 2.6.8) (7u121-2.6.8-1ubuntu0.14.04.3)
OpenJDK 64-Bit Server VM (build 24.121-b00, mixed mode)

javac 1.7.0_121

我装的android studio版本是2.3.2，用他创建、运行、编译项目都没有问题的

现在我想用命令行的模拟器，android命令已经过期了

The "android" command is deprecated.
For manual SDK, AVD, and project management, please use Android Studio.
For command-line tools, use tools/bin/sdkmanager and tools/bin/avdmanager

我运行avdmanager报如下错误

Exception in thread "main" java.lang.UnsupportedClassVersionError: com/android/sdklib/tool/AvdManagerCli : Unsupported major.minor version 52.0

不知道该如何解决

Answer 1

估计是你更新了sdk的原因，新版的sdk舍弃了android command,可以尝试用旧版本的sdk tool覆盖

Answer 2

我和你遇到的问题一样。
