QPython already has millions of users worldwide and it is also an open source project.

For different usage scenarios, QPython has two branches, namely QPython Ox and 3x.

QPython Ox is mainly aimed at programming learners, and it provides more friendly features for beginners. 

This is the QPython 3L, it is mainly for experienced Python users, and it provides some advanced technical features.

# Amazing Features
- Offline Python 3 interpreter: no Internet is required to run Python programs
- It supports running multiple types of projects, including: console program, SL4A program, webapp program
- Convenient QR code reader for transferring codes to your phone
- QPYPI and a custom repository for prebuilt wheel packages for enhanced scientific libraries, such as numpy, scipy, matplotlib, scikit-learn etc
- Easy-to-use editor
- INTEGRATED & EXTENDED SCRIPT LAYER FOR ANDROID LIBRARY (SL4A): IT LETS YOU DRIVE THE ANDROID WORK WITH PYTHON
- Good documentation and customer support

# SL4A Features
With SL4A features, you can use Python programming to control Android work:

- Android Apps API, such as: Application, Activity, Intent & startActivity, SendBroadcast, PackageVersion, System, Toast, Notify, Settings, Preferences, GUI
- Android Resources Manager, such as: Contact, Location, Phone, Sms, ToneGenerator, WakeLock, WifiLock, Clipboard, NetworkStatus, MediaPlayer
- Third App Integrations, such as: Barcode, Browser, SpeechRecongition, SendEmail, TextToSpeech
- Hardwared Manager: Carmer, Sensor, Ringer & Media Volume, Screen Brightness, Battery, Bluetooth, SignalStrength, WebCam, Vibrate, NFC, USB

[ IMPORTANT NOTE ]
IT MAY REQUIRE THE BLUETOOTH / LOCATION / READ_SMS / SEND_SMS / CALL_PHONE AND OTHER PERMISSIONS, SO THAT YOU CAN PROGRAM ITH THESE FEATURES. QPYTHON WILL NOT USE THESE PERMISSIONS IN BACKGROUND.

IF YOU GET EXCEPTION IN RUNTIME WHILE USING SL4A API, PLEASE CHECK WHETHER THE RELEVANT PERMISSIONS IN THE SYSTEM SETTINGS ARE ENABLED.

[ FAQ ]
A: Why can't I use the SMS API of SL4A
Q: Because Google Play and some app stores have strict requirements on the permissions of apps, in QPython 3x, we use x to distinguish branches with different permissions or appstores. For example, L means LIMITED and S means SENSITIVE.
Sometimes you cannot use the corresponding SL4A APIs because the version you installed does not have the corresponding permissions, so you can consider replace what you have installed with the right one.

＃关于QPython 3L
QPython是Android的Python引擎。它包含一些惊人的功能，例如Python解释器，运行时环境，编辑器，QPYI和SL4A库。它使您可以轻松在Android上使用Python。而且是免费的。

QPython已经在全球拥有数百万的用户，并且它也是一个开源项目。

对于不同的使用场景，QPython有两个分支，即QPython Ox和3x。

QPython Ox主要针对编程学习者，它为初学者提供了更友好的功能。

这是QPython 3L，主要面向经验丰富的Python用户，它提供了一些高级技术功能。

＃惊人的功能
-离线Python 3解释器：运行Internet程序不需要互联网
-它支持运行多种类型的项目，包括：控制台程序，SL4A程序，webapp程序
-便捷的QR码阅读器，可将代码传输到手机
-QPYPI和用于预装车轮套件的自定义存储库，用于增强型科学库，例如numpy，scipy，matplotlib，scikit-learn等
-易于使用的编辑器
-ANDROID库（SL4A）的集成和扩展脚本层：它使您可以使用PYTHON来驱动ANDROID工作
-良好的文档和客户支持

＃SL4A功能
借助SL4A功能，您可以使用Python编程来控制Android工作：

-Android Apps API，例如：应用程序，活动，意图和startActivity，SendBroadcast，PackageVersion，系统，Toast，通知，设置，首选项，GUI
-Android资源管理器，例如：联系人，位置，电话，短信，ToneGenerator，WakeLock，WifiLock，剪贴板，NetworkStatus，MediaPlayer
-第三应用集成，例如：条形码，浏览器，SpeechRecongition，SendEmail，TextToSpeech
-硬件管理器：卡默，传感器，铃声和媒体音量，屏幕亮度，电池，蓝牙，SignalStrength，WebCam，Vibrate，NFC，USB

[ 重要的提示 ]
它可能需要蓝牙/位置/ READ_SMS / SEND_SMS / CALL_PHONE和其他权限，以便您可以对这些功能进行编程。 QPYTHON将不会在后台使用这些权限。

如果您在使用SL4A API时在运行时异常，请检查是否启用了系统设置中的相应权限。

[ 常问问题 ]
答：为什么我不能使用SL4A的SMS API
问：由于Google Play和某些应用商店对应用的权限有严格的要求，因此在QPython 3x中，我们使用x来区分具有不同权限或应用商店的分支。例如，L表示LIMITED，S表示SENSITIVE。
有时您不能使用相应的SL4A API，因为安装的版本没有相应的权限，因此您可以考虑用正确的版本替换已安装的版本。
