第一次加载大概需要5到10分钟...
正常情况下，加载完成后软件会自动跳转到图形界面

在图形界面时，点击即鼠标左键
长按为鼠标右键
双指点击弹出键盘
双指划动为鼠标滚轮

在图形界面返回，可以回到终端界面和控制界面
你可以在控制界面安装更多软件或者阅读帮助信息

请不要在安装时退出软件

如果过了很长时间都没有加载完成
可以去设置里看看小小电脑占用空间是不是一直没变
如果是说明卡在什么地方了
建议清除本软件数据重来一次

(有一位网友提到过
自己无论怎么清软件数据都装不上
但在重启手机之后就装上了)

一些注意事项：
此软件以GPL协议免费开源
如果是买的就是被骗了, 请举报
源代码在这里: https://github.com/Cateners/tiny_computer
软件也会第一时间在这里更新
请尽可能在这里下载软件, 确保是正版

常见问题：
如果你的系统版本大于等于android 12
可能会在使用过程中异常退出(返回错误码9)
届时本软件会提供方案指引你修复
并不难
但是软件没有权限
不能帮你修复

如果你的系统版本大于等于android 13
那么很可能一些网页应用如jupyter notebook
bilibili客户端等等不可用
可以去全局设置开启getifaddrs桥接

如果你给了存储权限
那么通过主目录下的文件夹
就可以访问设备存储
要访问整个设备存储可以访问sd文件夹
此外主文件夹的很多文件夹与设备文件夹绑定
比如主文件夹的下载文件夹就是设备的下载文件夹

如果没有给存储权限
文件保存到下载文件夹时可能出现问题
(火狐浏览器可能因此无法下载文件)
你也可以选择换一个文件夹保存

如果你想安装其他软件
可以使用容器自带的tmoe
但并不保证安装了能用哦
(事实上, 目前容器里的
VSCode、输入法
都是用tmoe安装的
就连系统本身也是用tmoe安装的)

也可以在网上搜索
"ubuntu安装xxx教程"
"linux安装xxx教程"等等
本软件也提供一些基本软件安装按钮
包括图形处理, 视频剪辑, 科学计算相关的软件
稍后你就会看到

如果你需要更多字体
在给了存储权限的情况下
直接将字体复制到设备存储的Fonts文件夹即可
一些常用的办公字体
可以在Windows电脑的C:\\Windows\\Fonts文件夹找到
由于可能的版权问题
软件不能帮你做

关于中文输入的问题
强烈建议不要使用安卓中文输入法直接输入中文
而是使用英文键盘通过容器的输入法(Ctrl+空格切换)输入中文
避免丢字错字

如果你遇到了问题
可以去https://github.com/Cateners/tiny_computer/issues/
留言反馈

如果软件里有程序正在正常运行
请不要强行关闭本软件
否则可能会损坏容器
(如dpkg被中断)
特别是在安装某些比较大的软件的时候

感谢使用!

(顺带一提, 全部解压完大概需要4~5GB空间
解压途中占用空间可能更多
请确保有足够的空间
(这样真的Tiny吗><))

                        http://www.apache.org/licenses/

   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION

      "License" shall mean the terms and conditions for use, reproduction,
      and distribution as defined by Sections 1 through 9 of this document.

      "Licensor" shall mean the copyright owner or entity authorized by
      the copyright owner that is granting the License.

      "Legal Entity" shall mean the union of the acting entity and all
      other entities that control, are controlled by, or are under common
      control with that entity. For the purposes of this definition,

      direction or management of such entity, whether by contract or
      otherwise, or (ii) ownership of fifty percent (50%) or more of the
      outstanding shares, or (iii) beneficial ownership of such entity.

      "You" (or "Your") shall mean an individual or Legal Entity
      exercising permissions granted by this License.

      "Source" form shall mean the preferred form for making modifications,
      including but not limited to software source code, documentation
      source, and configuration files.

      "Object" form shall mean any form resulting from mechanical
      transformation or translation of a Source form, including but
      not limited to compiled object code, generated documentation,
      and conversions to other media types.

      "Work" shall mean the work of authorship, whether in Source or
      Object form, made available under the License, as indicated by a
      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).

      "Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain
      separable from, or merely link (or bind by name) to the interfaces of,
      the Work and Derivative Works thereof.

      "Contribution" shall mean any work of authorship, including
      the original version of the Work and any modifications or additions
      to that Work or Derivative Works thereof, that is intentionally
      submitted to Licensor for inclusion in the Work by the copyright owner
      or by an individual or Legal Entity authorized to submit on behalf of
      the copyright owner. For the purposes of this definition, "submitted"
      means any form of electronic, verbal, or written communication sent
      to the Licensor or its representatives, including but not limited to
      communication on electronic mailing lists, source code control systems,
      and issue tracking systems that are managed by, or on behalf of, the
      Licensor for the purpose of discussing and improving the Work, but
      excluding communication that is conspicuously marked or otherwise
      designated in writing by the copyright owner as "Not a Contribution."

      "Contributor" shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and
      subsequently incorporated within the Work.

   2. Grant of Copyright License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.

   3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

   END OF TERMS AND CONDITIONS

   APPENDIX: How to apply the Apache License to your work.

这个软件预计会有一些广告
分为横幅广告和视频广告
横幅广告在终端和控制页面的顶端出现
(但不知道是不是因为代码没写对
反正我从没见横幅广告成功加载过)
视频广告在需要解锁某些功能时自行观看

这些功能需要累计完整观看对应数目广告后永久解锁：
启用终端: 观看2个广告
启用小键盘: 观看3个广告
关闭横幅广告: 观看5个广告
终端最大行数修改: 观看6个广告
推流参数修改: 观看8个广告
启用virgl加速: 观看10个广告
HiDPI环境变量修改: 观看12个广告

我设置了每天最多可以看5个广告。
只要看满1个广告, 就可以在本次使用期间临时解锁全部功能。
只要看满2个广告, 就可以在当日使用期间临时解锁全部功能。

总之为了良好的体验
在图形界面是不会出现广告的
这点还请放心

---注意事项---

我注意到Unity提供了一些不那么合适的广告
一般如果我看到这些广告就在后台直接禁了
不过也可能有漏网之鱼
可以联系我禁掉
