是否可以在 Termux 中安装 Java SDK？

Question

我在尝试在我的 Android 设备上安装 Java SDKs 时遇到问题。

我需要安装它才能在Termux 中使用apktool。我在许多论坛甚至 YouTube 上进行了调查，但我无法解决我的问题。我用了这个script，但它也对我不起作用；我得到Bad system call。我已经安装了apktool，但是我缺少Java 插件才能正常工作。谁能帮帮我？

它正在这款平板电脑上运行。其他平板电脑仍然不行。

$ java
Usage: java [options] <mainclass> [args...]
           (to execute a class)
   or  java [options] -jar <jarfile> [args...]
           (to execute a jar file)
   or  java [options] -m <module>[/<mainclass>] [args...]
       java [options] --module <module>[/<mainclass>] [args...]
           (to execute the main class in a module)

 Arguments following the main class, -jar <jarfile>, -m or --module
 <module>/<mainclass> are passed as the arguments to main class.

 where options include:

    -d32          Deprecated, will be removed in a future release
    -d64          Deprecated, will be removed in a future release
    -client       is a synonym for the "server" VM  [deprecated]
    -cp <class search path of directories and zip/jar files>

    --module-path <module path>...
                  A : separated list of directories, each directory
                  is a directory of modules.
    --upgrade-module-path <module path>...
                  A : separated list of directories, each directory
                  is a directory of modules that replace upgradeable
                  modules in the runtime image
    --add-modules <module name>[,<module name>...]
                  root modules to resolve in addition to the initial module.
                  <module name> can also be ALL-DEFAULT, ALL-SYSTEM,

    --dry-run     create VM and load main class but do not execute main method.

    --validate-modules
                  validate all modules and exit
                  The --validate-modules option may be useful for finding

    -D<name>=<value>
                  set a system property
    -verbose:[class|module|gc|jni]

    -version      print product version to the error stream and exit
    --version     print product version to the output stream and exit
    -showversion  print product version to the error stream and continue
    --show-version
                  print product version to the output stream and continue
    --show-module-resolution
                  show module resolution output during startup
    -? -h -help
                  print this help message to the error stream

    -enableassertions[:<packagename>...|:<classname>]
                  enable assertions with specified granularity
    -da[:<packagename>...|:<classname>]
    -disableassertions[:<packagename>...|:<classname>]
                  disable assertions with specified granularity
    -esa | -enablesystemassertions
                  enable system assertions
    -dsa | -disablesystemassertions

                  HiDPI scaled images are automatically supported and used
                  if available. The unscaled image filename, e.g. image.ext,
                  should always be passed as the argument to the -splash option.
                  The most appropriate scaled image provided will be picked up
                  automatically.
                  See the SplashScreen API documentation for more information
    @argument files
                  one or more argument files containing options
