GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright � 1991, 1999 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also counts
as the successor of the GNU Library Public License, version 2, hence
the version number 2.1.]
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some
specially designated software packages--typically libraries--of the
Free Software Foundation and other authors who decide to use it. You
can use it too, but we suggest you first think carefully about whether
this license or the ordinary General Public License is the better
strategy to use in any particular case, based on the explanations below.
When we speak of free software, we are referring to freedom of use,
not price. Our General Public Licenses are designed to make sure that
you have the freedom to distribute copies of free software (and charge
for this service if you wish); that you receive source code or can get
it if you want it; that you can change the software and use pieces of
it in new free programs; and that you are informed that you can do
these things.
To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights. These restrictions translate to certain responsibilities for
you if you distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get the source
code. If you link other code with the library, you must provide
complete object files to the recipients, so that they can relink them
with the library after making changes to the library and recompiling
it. And you must show them these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal
permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that
there is no warranty for the free library. Also, if the library is
modified by someone else and passed on, the recipients should know
that what they have is not the original version, so that the original
author's reputation will not be affected by problems that might be
introduced by others.
Finally, software patents pose a constant threat to the existence of
any free program. We wish to make sure that a company cannot
effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder. Therefore, we insist that
any patent license obtained for a version of the library must be
consistent with the full freedom of use specified in this license.

Android 10是Google在2019年发布的最新Android操作系统版本,其主要目标是提供更优秀的用户体验,强化隐私安全,以及引入一系列新功能和技术改进。Android 10的更新内容广泛,涵盖性能优化、用户界面调整、权限管理、手势导航等多个方面。以下是关于这个系统image的一些关键知识点:
1. **权限管理**:Android 10进一步增强了应用权限的管理,用户可以对位置信息的访问进行更加精细化的控制,可以选择仅在应用运行时才允许访问位置信息,提高隐私保护。
2. **黑暗模式**:Android 10引入了全局黑暗模式,不仅有助于节省电池,在低光照环境下也更护眼。开发者可以通过API实现与系统的黑暗模式无缝集成。
3. **手势导航**:新的手势导航系统取代了传统的三键导航,用户只需滑动屏幕边缘即可实现返回、主页和多任务切换等操作,提供了更为直观的交互体验。
4. **隐私保护**:Android 10加强了对用户数据的保护,比如剪贴板数据的使用限制,以及应用在后台获取位置信息的限制,确保用户数据安全。
5. **聚焦模式**(Digital Wellbeing):这一功能旨在帮助用户更好地管理数字生活,可以设置应用的时间限制,到了设定时间后,应用会自动进入灰度模式,提示用户休息。
6. **折叠屏设备支持**:随着折叠屏手机的出现,Android 10为这类设备提供了原生支持,包括灵活的屏幕布局和多窗口模式。
7. **Live Caption**:实时字幕功能,可以在任何音频播放时自动生成字幕,无需网络连接,对听力障碍用户非常友好。
8. **Wi-Fi性能管理器**:系统能够智能地管理Wi-Fi连接,提高网络稳定性,并在不同Wi-Fi网络间无缝切换。
9. **安全更新**:Android 10通过更快的安全更新推送机制,使设备能更快获得最新的安全补丁,提升系统安全性。
10. **共享菜单优化**:分享内容时,Android 10的共享菜单更加简洁高效,根据用户的分享习惯,会优先显示常用的分享选项。
11. **家长控制**:Android 10的Family Link功能得到增强,父母可以更好地监控孩子的设备使用情况,设置使用时间限制和应用安装权限。
12. **5G支持**:系统为即将到来的5G网络做了准备,优化了网络性能和功耗管理,确保在5G环境下流畅运行。
13. **Project Mainline**:Google推出的新项目,部分安全和性能更新将通过Play商店直接推送,无需等待厂商更新系统。
14. **开发者特性**:包括对可折叠设备的API支持、新的Android Studio工具、Jetpack库更新等,帮助开发者创建更高质量的应用。
以上是Android 10系统image的一些核心特性。在解压的"default"文件中,可能包含的是官方的系统镜像文件,用于刷机或开发工作。通常,这些系统image文件包括内核、系统分区、恢复分区等组件,用户或开发者可以使用它们来安装或测试Android 10系统。刷机前,确保备份重要数据,遵循正确的刷机教程,以免造成数据丢失或设备损坏。
