有没有办法在Android上运行Python?

问题:有没有办法在Android上运行Python?

我们正在开发S60版本,该平台具有不错的Python API。

但是,关于Android上的Python尚无官方资料,但是由于Jython存在,有没有办法让蛇和机器人一起工作?

We are working on an S60 version and this platform has a nice Python API..

However, there is nothing official about Python on Android, but since Jython exists, is there a way to let the snake and the robot work together??

还有一个新的Android脚本环境(ASE / SL4A)项目。它看起来很棒,并且与本机Android组件集成在一起。

注意:不再处于“主动开发”之下,但是可能有一些分支。

There is also the new Android Scripting Environment (ASE/SL4A) project. It looks awesome, and it has some integration with native Android components.

Note: no longer under “active development”, but some forks may be.

是! :Android脚本环境

一个例子通过马特·卡茨通过SL4A – “这是写在Python代码半年线条码扫描器:

import android
droid = android.Android()
code = droid.scanBarcode()
isbn = int(code['result']['SCAN_RESULT'])
url = "http://books.google.com?q=%d" % isbn
droid.startActivity('android.intent.action.VIEW', url)

Yes! : Android Scripting Environment

An example via Matt Cutts via SL4A — “here’s a barcode scanner written in six lines of Python code:

import android
droid = android.Android()
code = droid.scanBarcode()
isbn = int(code['result']['SCAN_RESULT'])
url = "http://books.google.com?q=%d" % isbn
droid.startActivity('android.intent.action.VIEW', url)

适用于Android的Pygame子集

Pygame是适用于Python(在桌面上)的2D游戏引擎,在新程序员中很流行。AndroidPygame子集将自己描述为…

…将Pygame功能的子集移植到Android平台。该项目的目标是允许创建特定于Android的游戏,并简化游戏从类似PC的平台到Android的移植。

示例包括打包为APK的完整游戏,这很有趣。

Pygame Subset for Android

Pygame is a 2D game engine for Python (on desktop) that is popular with new programmers. The Pygame Subset for Android describes itself as…

…a port of a subset of Pygame functionality to the Android platform. The goal of the project is to allow the creation of Android-specific games, and to ease the porting of games from PC-like platforms to Android.

The examples include a complete game packaged as an APK, which is pretty interesting.

交叉编译和Ignifuga

我的博客上有说明和补丁用于Android的Python 2.7.2交叉编译的。

我还开源了我的2D游戏引擎Ignifuga。它基于Python / SDL,并且可以为Android交叉编译。即使您不将它用于游戏,您也可能会从代码或构建器实用程序(以Tim 命名的Schafer ……知道谁)中得到有用的想法。

Cross-Compilation & Ignifuga

My blog has instructions and a patch for cross compiling Python 2.7.2 for Android.

I’ve also open sourced Ignifuga, my 2D Game Engine. It’s Python/SDL based, and it cross compiles for Android. Even if you don’t use it for games, you might get useful ideas from the code or builder utility (named Schafer, after Tim… you know who).

Android脚本层

SL4A做您想要的。您可以轻松地将其从其站点直接安装到设备上,而无需root用户。

它支持多种语言。Python是最成熟的。默认情况下,它使用Python 2.6,但是您可以使用3.2端口。我已经将该端口用于Galaxy S2上的所有东西,并且工作正常。

API

SL4A android为每种支持的语言提供了其库的端口。该库通过单个Android对象提供了与基础Android API的接口。

from android import Android

droid = Android()
droid.ttsSpeak('hello world') # example using the text to speech facade

每种语言都有几乎相同的API。您甚至可以在webview中使用JavaScript API。

let droid = new Android();
droid.ttsSpeak("hello from js");

使用者介面

对于用户界面,您有三个选择:

  • 您可以通过API轻松使用通用的本机对话和菜单。这对于确认对话和其他基本用户输入很有用。
  • 您还可以从Python脚本中打开Web视图,然后将HTML5用作用户界面。当您使用Python中的Web视图时,可以在Web视图和生成它的Python进程之间来回传递消息。用户界面不会是本机的,但仍然是一个不错的选择。
  • 一些对Android本机用户界面的支持,但是我不确定它的运行情况如何;我只是从未使用过它。

您可以混合使用选项,因此您可以在主界面上拥有一个Web视图,并且仍然使用本机对话。

QPython的

有一个名为QPython的第三方项目。它建立在SL4A之上,并抛出了其他有用的东西。

QPython为您提供了一个更好的UI来管理安装,并包括一个小的触摸屏代码编辑器,一个Python Shell和一个用于程序包管理的PIP Shell。它们还具有Python 3端口。两种版本均可从Play商店免费获得。QPython还在Android项目(包括Kivy)上捆绑了来自大量Python的库,因此它不仅仅是SL4A。

请注意,QPython仍在开发SL4A的分支(尽管,说实话,没有太多)。SL4A的主要项目本身已经死了。

有用的链接

Scripting Layer for Android

SL4A does what you want. You can easily install it directly onto your device from their site, and do not need root.

It supports a range of languages. Python is the most mature. By default, it uses Python 2.6, but there is a 3.2 port you can use instead. I have used that port for all kinds of things on a Galaxy S2 and it worked fine.

API

SL4A provides a port of their android library for each supported language. The library provides an interface to the underlying Android API through a single Android object.

from android import Android

droid = Android()
droid.ttsSpeak('hello world') # example using the text to speech facade

Each language has pretty much the same API. You can even use the JavaScript API inside webviews.

let droid = new Android();
droid.ttsSpeak("hello from js");

User Interfaces

For user interfaces, you have three options:

  • You can easily use the generic, native dialogues and menus through the API. This is good for confirmation dialogues and other basic user inputs.
  • You can also open a webview from inside a Python script, then use HTML5 for the user interface. When you use webviews from Python, you can pass messages back and forth, between the webview and the Python process that spawned it. The UI will not be native, but it is still a good option to have.
  • There is some support for native Android user interfaces, but I am not sure how well it works; I just haven’t ever used it.

You can mix options, so you can have a webview for the main interface, and still use native dialogues.

QPython

There is a third party project named QPython. It builds on SL4A, and throws in some other useful stuff.

QPython gives you a nicer UI to manage your installation, and includes a little, touchscreen code editor, a Python shell, and a PIP shell for package management. They also have a Python 3 port. Both versions are available from the Play Store, free of charge. QPython also bundles libraries from a bunch of Python on Android projects, including Kivy, so it is not just SL4A.

Note that QPython still develop their fork of SL4A (though, not much to be honest). The main SL4A project itself is pretty much dead.

作为一个Python的爱好者和Android程序员,我很伤心地说,这是不是一个很好的路要走。有两个问题:

一个问题是,Android开发工具不只是一种编程语言。许多Android图形涉及XML文件来配置显示,类似于HTML。内置的Java对象与此XML布局集成在一起,比编写代码从逻辑到位图要容易得多。

另一个问题是G1(以及不久的将来可能还有其他Android设备)的运行速度并不快。200 MHz处理器和RAM非常有限。即使是在Java中,如果要使应用程序完全流畅,也必须进行大量重写以避免创建更多对象。在移动设备上运行一段时间后,Python将变得太慢。

As a Python lover and Android programmer, I’m sad to say this is not a good way to go. There are two problems:

One problem is that there is a lot more than just a programming language to the Android development tools. A lot of the Android graphics involve XML files to configure the display, similar to HTML. The built-in java objects are integrated with this XML layout, and it’s a lot easier than writing your code to go from logic to bitmap.

The other problem is that the G1 (and probably other Android devices for the near future) are not that fast. 200 MHz processors and RAM is very limited. Even in Java, you have to do a decent amount of rewriting-to-avoid-more-object-creation if you want to make your app perfectly smooth. Python is going to be too slow for a while still on mobile devices.

基维

我想补充一下@JohnMudd关于Kivy的文章。自从他描述这种情况以来已经有好几年了,而Kivy有了长足的发展。

我认为,Kivy的最大卖点是其跨平台兼容性。您可以使用任何桌面环境(Windows / * nix等)对所有内容进行编码和测试,然后将您的应用打包到一系列不同的平台上,包括Android,iOS,MacOS和Windows(尽管应用通常缺乏本机外观)。

使用Kivy自己的KV语言,您可以轻松编码和构建GUI界面(就像Java XML一样,但不是TextView等,KV拥有自己的ui.widgets的类似翻译功能),我认为这很容易采用。

当前,最推荐使用Buildozerpython-for-android工具来构建和打包应用程序。我对它们都进行了尝试,可以肯定地说,它们使使用Python构建Android应用程序变得轻而易举。他们的指南也有据可查。

iOS是Kivy的另一个大卖点。您可以使用相同的代码库,通过kivy-ios Homebrew工具进行少量更改,尽管构建需要Xcode,但在其设备上运行之前(AFAIK,Xcode中的iOS Simulator当前不适用于x86体系结构构建) 。为了成功构建,还必须手动在Xcode中解决一些依赖项问题,并加以解决,但这并不太容易解决,并且Kivy Google Group的人员也非常有帮助。

综上所述,具有良好Python知识的用户应该不会有任何问题,很快就能掌握基础知识。

如果将Kivy用于更重要的项目,则可能会发现现有模块不令人满意。虽然有一些可行的解决方案。通过适用于Android的pyjniuspyobjus,用户现在可以访问Java / Objective-C类来控制某些本机API。

Kivy

I wanted to add to what @JohnMudd has written about Kivy. It has been years since the situation he described, and Kivy has evolved substantially.

The biggest selling point of Kivy, in my opinion, is its cross-platform compatibility. You can code and test everything using any desktop environment (Windows/*nix etc.), then package your app for a range of different platforms, including Android, iOS, MacOS and Windows (though apps often lack the native look and feel).

With Kivy’s own KV language, you can code and build the GUI interface easily (it’s just like Java XML, but rather than TextView etc., KV has its own ui.widgets for a similar translation), which is in my opinion quite easy to adopt.

Currently Buildozer and python-for-android are the most recommended tools to build and package your apps. I have tried them both and can firmly say that they make building Android apps with Python a breeze. Their guides are well documented too.

iOS is another big selling point of Kivy. You can use the same code base with few changes required via kivy-ios Homebrew tools, although Xcode is required for the build, before running on their devices (AFAIK the iOS Simulator in Xcode currently doesn’t work for the x86-architecture build). There are also some dependency issues which must be manually compiled and fiddled around with in Xcode to have a successful build, but they wouldn’t be too difficult to resolve and people in Kivy Google Group are really helpful too.

With all that being said, users with good Python knowledge should have no problem picking up the basics quickly.

If you are using Kivy for more serious projects, you may find existing modules unsatisfactory. There are some workable solutions though. With the (work in progress) pyjnius for Android, and pyobjus, users can now access Java/Objective-C classes to control some of the native APIs.

使用SL4A(在其他答案中已经提到过),您可以运行成熟的web2py实例(其他python web框架也可能是候选对象)。SL4A不允许您执行本机UI组件(按钮,滚动条等),但它确实支持WebViews。WebView基本上只不过是指向固定地址的带状结构的Web浏览器。我相信本机Gmail应用程序使用WebView而非常规的窗口小部件路线。

这条路线将具有一些有趣的功能:

  • 对于大多数python网络框架,您实际上可以在不使用android设备或android模拟器的情况下进行开发和测试。
  • 无论您最终为手机编写的任何Python代码,也都可以进行很小的修改(如果有的话)放在公共Web服务器上。
  • 您可以利用那里所有疯狂的网络内容:查询,HTML5,CSS3等。

Using SL4A (which has already been mentioned by itself in other answers) you can run a full-blown web2py instance (other python web frameworks are likely candidates as well). SL4A doesn’t allow you to do native UI components (buttons, scroll bars, and the like), but it does support WebViews. A WebView is basically nothing more than a striped down web browser pointed at a fixed address. I believe the native Gmail app uses a WebView instead of going the regular widget route.

This route would have some interesting features:

  • In the case of most python web frameworks, you could actually develop and test without using an android device or android emulator.
  • Whatever Python code you end up writing for the phone could also be put on a public webserver with very little (if any) modification.
  • You could take advantage of all of the crazy web stuff out there: query, HTML5, CSS3, etc.
