一键消失手机相册图片等文件,开发了一个安卓手机脚本执行器

## 开发背景
开发了一个安卓 shell 脚本执行器 app
开发工具: Android Studio
编程语言: Java
实现功能可以在里面填入任意语法正确可以运行的脚本，然后可以根据这个脚本生成自定义的桌面快捷方式。点击手机桌面方式就可以执行，比如现在点击以下这个保存的脚本生成的桌面快捷方式，手机相册文件全部消失，打开相册没有图片，并且整理到指定目录。

## 脚本示例
以前用的是 mt 管理器执行的，现在搞了一个独立的万能脚本执行器。

```bash
#!/system/bin/sh

# 获取当前日期作为目录前缀，格式：YYYYMMDD
today=$(date +%Y%m%d)

# 定义目标根目录：隐藏主目录 + 固定中文子目录
root_hidden_dir="/storage/emulated/0/.sjwj/xxxx 手机文件"
target_base="$root_hidden_dir/${today}xxxx 手机文件"

# 创建目标根目录
mkdir -p "$target_base"

# 1. 处理 Download 根目录下的普通文件
download_src="/storage/emulated/0/Download"
download_dst="$target_base/Download 根文件"
if find "$download_src" -maxdepth 1 -type f | grep -q .; then
mkdir -p "$download_dst"
find "$download_src" -maxdepth 1 -type f -exec mv -n {} "$download_dst/" \;
fi

# 1.1 处理 DCIM 根目录下的普通文件
dcim_src="/storage/emulated/0/DCIM"
dcim_dst="$target_base/DCIM 根文件"
if find "$dcim_src" -maxdepth 1 -type f | grep -q .; then
mkdir -p "$dcim_dst"
find "$dcim_src" -maxdepth 1 -type f -exec mv -n {} "$dcim_dst/" \;
fi

# 1.2 处理 Movies 根目录下的普通文件
movies_src="/storage/emulated/0/Movies"
movies_dst="$target_base/Movies 根文件"
if find "$movies_src" -maxdepth 1 -type f | grep -q .; then
mkdir -p "$movies_dst"
find "$movies_src" -maxdepth 1 -type f -exec mv -n {} "$movies_dst/" \;
fi

# 1.3 处理 Pictures 根目录下的普通文件
pictures_src="/storage/emulated/0/Pictures"
pictures_dst="$target_base/Pictures 根文件"
if find "$pictures_src" -maxdepth 1 -type f | grep -q .; then
mkdir -p "$pictures_dst"
find "$pictures_src" -maxdepth 1 -type f -exec mv -n {} "$pictures_dst/" \;
fi

# 2. 统一处理各类子目录，按上级目录归类排序（不含根目录）
