Python for Android supports lxml. But how can I import it? On the google site, there is a modul in a recipe.sh file. But i can not run it through the shell there. I get some errors:
app_122#android:/mnt/sdcard $ sh recipe.sh
: nor found]
recipe.sh[6]: get_directory: not found
: not found]
recipe.sh[9]: syntax error: '{^M' expected
1 app_122#android:/mnt/sdcard
Can't I just get some .py file and simply import it into my programms?
I used this code:
https://github.com/kivy/python-for-android/blob/master/recipes/lxml/recipe.sh
Can someone help?
I think you might be confusing py4a which is a sister project of SL4A (Scripting Layer For Android) with https://github.com/kivy/python-for-android which is a sister project of Kivy
Both are different projects with different targets. You should be clear about which project you want to use. Read the docs to get more familiar.

I have made an apk by converting .py kivy with the help of buidozer in google colab. The earlier versions were working but now latest version is not working.
May be there is a problem in my .spec file so I am attaching it ...
At first I think my assest(images) are causing this problem but after removing them too it's not working.
I have done some research and got this buildozer -v android debug deploy run logcat but I don't know how to execute and use this command....
.spec file link : https://github.com/AyushRaj0305/APP/blob/main/.spec
All I want is that my apk should work in android
Thanks for Help
I have same issue in past and I solve by adding requirements in .spec
This requirements work for me:
requirements = hostpython3==3.7.8,python3==3.7.8,kivy==1.11.1, certifi,chardet, lxml, docutils, future, idna, Kivy-Garden, Pygments, requests, six, soupsieve, urllib3, deep-translator, arabic-reshaper, python-bidi, openssl, pyopenssl, numpy, pytz, python-dateutil, pandas, setuptools, zope.interface, datetime
you have to write all modules and parent module in requirements which your app is using.
To know module which you app is using has two method:
run command pip freeze in current app folder in powershell
install all the module as below photo which help to install your application module
I have debugged your code and found missing PIL
I want write simple application in Python for Android using kivy. Sadly when I start example code I see only splash screen and few second later application finish work. There is a huge problem with debugging because adb on Linux Mint does not detect my device.
Can someone look at my code and tell my why?
To build application I use buildozer. You can also see create_env script to check all dependencies are there.
Best regards.

EDIT:
I started debugging my application. Conclusion:
buildozer + python3 + kivy is a bad idea
if I use kivy.uix.button.Button when text attribute is str than I got exception "AttributeError: 'str' object has no attribute 'decode'"
if I use kivy.uix.button.Button when text attribute is bytes than I got exception "ValueError: Button.text accept only str"
It looks like loop with no solution. Some idea when I should report it?
Exception is in .buildozer/android/platform/build/build/python-installs/pad/android/init.py" file so it does not look like kivy and/or buildozer exception.
I've used python-for android tool and faced with the same errors. But in my case, app didn't run at all - crashed from splash screen. Finally, I've found a solution. You can try the same way.
So my pipeline was python3 + python-for-android (p4a tool, python-for-android, from master branch) + kivy (1.10.1)
There is a file "_android.pyx" for android building recipe (full list of avaliable p4a recipes you can see by command p4a recipes). This file is, possibly, used by Buildozer, and exactly used by P4A during APK building procedure. You need to fix it.
You may find it's location in Ubuntu (for example) via:
sudo updatedb
locate _android.pyx
It's path should be something like:
~/.local/lib/python3.6/site-packages/pythonforandroid/recipes/android/src/android/_android.pyx
There should be a string:
python_act = autoclass(JAVA_NAMESPACE.decode('utf-8') + u'.PythonActivity')
so you should change it - something like this:
python_act = autoclass(str(JAVA_NAMESPACE) + u'.PythonActivity'),
or just use some hardcode:
python_act = autoclass("org/kivy/android/PythonActivity")
Or there might be the other decode() usage in sources.
The reason: differences between Python2 and Python3 - the decode() method is usable on the equivalent binary data type in either Python 2 or 3, but it can’t be used by the textual data type consistently between Python 2 and 3 because str in Python 3 doesn’t have the method decode function has different realisation in Python3.

Hope, it will help you somehow.
is there someone who has experience with pyqtdeploy and adding external modules? I am currently using pyqtdeploy (version 1.2) together with PyQt 5.5.1 to write an application that can be deployed to an Android device. Without any external modules, the freezing with pyqtdeploy works pretty well. However, I am not really sure how I can add external modules (not pure Python ones) to my application.
In particular, I want to add the external module pycrypto. Therefore, I downloaded the pycrypto sourcecode, compiled it with the Android toolchain (from the Android NDK) and now I have a bunch of *.py and *.so files. How can I add them to my application?
My initial attempt was to add the *.py and the *.so files (so basically the whole pycrypto module) to the "Other Packages" tab in pyqtdeploy.
But now, when I import something pycrypto related in my application (from Crypto.Cipher import AES) i get the following error message:
File: ":/Crypto/Cipher/_AES.py", line 20 in __bootstrap__
TypeError: 'NoneType' object is not callable
The _AES.py file where the error is thrown, looks like this:
def __bootstrap__():
global __bootstrap__, __loader__, __file__
import sys, pkgutil, imp
__file__ = pkgutil.get_data(__name__,'_AES.cpython-34m.so')
__loader__ = None; del __bootstrap__, __loader__
imp.load_dynamic(__name__,__file__)
__bootstrap__()
At first I thought, that the *.so filename was just wrong and therefore, I got the NoneType Error, so I changed the filename in _AES.py to something other like 'test.so'. Surprisingly, now, I get a different error message than before:
File ":/pkgutil.py" line 629, in get_data
ImportError: qrcimporter: error opening file :/Crypto/Cipher/test.so
Ok, so the filename should be fine, right? But why do i get the 'NoneType` error message? What am I doing wrong? Is this the right way to accomplish this?
Any help is highly appreciated. I am pretty sure, that i'm only one small step away from getting this thing to work, but I can't figure out what i'm doing wrong.
Thanks!
Python for Android (Py4A 2.6) is wonderful!!! But QPython (2.7) is a lot more powerful and continuously developed. Now I try to integrate Qpython's Python into Android (5.1 CM12) Terminal / ADB described in this Tutorial:http://wiki.qpython.org/en/diveinto/
My Script to import the environment variables qpython needs looks like:
TERM=screen
PATH=/data/data/com.hipipal.qpyplus/files/bin:/system/bin:/system/xbin
LD_LIBRARY_PATH=.:/data/data/com.hipipal.qpyplus/files/lib/:/data/data/com.hipipal.qpyplus/files/:/data/data/com.hipipal.qpyplus/lib/
PYTHONHOME=/data/data/com.hipipal.qpyplus/files
ANDROID_PRIVATE=/data/data/com.hipipal.qpyplus/files

Shell session:
u0_a101#C1905:/ $ source /sdcard/qpyenvnew.sh
u0_a101#C1905:/ $ $python
u0_a101#C1905:/ $ hmm do nothing?!
I get no output.
I have found here on Stackoverflow the same Question but the posted solution ist a link how is down.
Other Tutorial on throws only errors
http://dinostest.com/node/28
Try this command in your terminal:
$sh data/data/com.hipipal.qpyplus/files/bin/qpython.sh
Terminal will prompt a Python console.
If your script for the environment variables was obtained by running the code from the tutorial link, it should be correct.
If what you have pasted is exactly what you entered, the problem would be that you tried to run pyhton by typing $python when it should have just been python
Pre-fixing with $ is used to reference the value of a variable, so entering $python referenced the value of the variable python but does nothing with it, hence no feedback.
EDIT2: Although it's not a direct answer to this question I suggest having a look at the App 'Termux'. You can install Python2/3 via apt, virtualenv/-wrapper etc... Much more powerfull!
EDIT: Since /data/data... is only accessible as root, the following must be done as root!
Take care that the python executables path is in your $PATH. That wasn't the case even after having run the script from the tutorial (your script). If it's not present simply type:export PATH=/data/data/com.hipipal.qpyplus/files/bin:$PATH
or follow theses steps. In short: create a file in /sdcard (here ".bashrc") with the above line. After that type: source .bashrcsource init.sh (init.sh is located in /data/data/com.hipipal.qpyplus/files/bin as well) Then fire up Python with python-android5 which is the PIE compatible executable for Phone with Lollipop and above. But be aware: For whatever reason I couldn't exit() or quit() the Python prompt but I was able to run Script from the Terminal! Have fun!
EDIT: I spotted this: PythonForAndroid. It is a fork of PythonForAndroid that is still alive, and this versions are able to run on Android L (Python3 on 5.1.1 in my case). Also check the SL4A linked there, it works great on Lollipop.
Thanks to the answers above I made a super easy solution. If you have root: Create a file "python" and type the following line in it:
sh data/data/com.hipipal.qpyplus/files/bin/qpython-android5.sh
Place this file in your /system/bin directory and you can access python from everywhere using the command 'python'.
I just can't find the help.py file in order to create the API reference for the monkeyrunner. The command described at the Android references
monkeyrunner <format> help.py <outfile> does not work when i call monkeyrunner html help.py /path/to/place/the/doc.html.
It's quite obvious that the help.py file is not found and the monkeyrunner also tells me "Can't open specified script file". But a locate on my system doesn't bring me a help.py file that has anything to do with monkeyrunner or Android.
So my question is: Where did they hide the help.py file for creating the API reference?
I cannot find it either. But one can assume that it is simply calling MonkeyRunner.help() with the passed in arguments. If you just want to get something quick use this script I created also named help.py:
#!/usr/bin/env python
# Imports the monkeyrunner modules used by this program
from com.android.monkeyrunner import MonkeyRunner, MonkeyDevice
text = MonkeyRunner.help("html");
f = open('help.html', 'w')
f.write(text);
f.close();
Run it just like any other monkeyrunner script:
$ monkeyrunner help.py
After I have all codes in my machine (i.e, repo sync), it is at mydroid/sdk/monkeyrunner/scripts along with other three:
help.py monkey_playback.py monkey_recorder.py mr_pydoc.py
This is brilliant answer https://stackoverflow.com/a/4470513/551383 but if you really want this file is in android source i.e. http://androidxref.com/4.2_r1/xref/sdk/monkeyrunner/scripts/help.py
http://androidxref.com/source/xref/sdk/monkeyrunner/scripts/help.py
I believe the documentation on the website starts from that script, but I'm pretty sure somebody edits it a bit afterwards as well.
There's an error in monkeyrunner's help documentation (monkeyrunner Built-in Help), you should use parameters in another order:
monkeyrunner help.py <format> <outfile>
And don't forget about specifying a full path to the script, if you're running it outside of the monkeyrunner.bat directory (android monkeyrunner scripts).
If you don't have Repo Sync, described by users above, you can find the sources (including help.py), for example, here: monkeyrunner scripts.
I opened an issue at Google Code (Issue 26259: monkeyrunner Built-in Help Description Error) and I hope that they'll fix it soon.
