Context.setLanguageVersion介绍

[英]Set the language version.

Setting the language version will affect functions and scripts compiled subsequently. See the overview documentation for version-specific behavior.
[中]设置语言版本。
设置语言版本将影响随后编译的函数和脚本。有关特定于版本的行为，请参阅概述文档。

/**

  // we need to make sure that exit the context.

   // and android runs on DEX bytecode. Instead we need to go in interpreted mode.
