Android :: Modify Python USB Device Driver To Only Use Vendor_id And Product_id - Excluding BCD

Mar 27, 2010

I'm trying to modify the Android device driver for calibre (an e-book management program) so that it identifies devices by only vendor id and product id, and excludes BCD.

The driver is a fairly simply python plugin, and is currently set up to use all three numbers, but apparently, when Android devices use custom Android builds (ie CyanogenMod for the Nexus One), it changes the BCD so calibre stops recognizing it.

The current code looks like this, with a simple list of vendor id's, that then have allowed product id's and BCD's with them:


The line I'm specifically trying to change is:


Which is, the line for identifying a Nexus One. My N1, running CyanogenMod 5.0.5, has the BCD 0x226, and rather than just adding it to the list, I'd prefer to eliminate the BCD from the recognition process, so that any device with vendor id 0x18d1 and product id 0x4e11 or 0x4e12 would be recognized. The custom Android rom doesn't change enough for the specifics to matter.

The syntax seems to require the BCD in brackets.

How can I edit this so that it matches anything in that field?

General :: Device Information With Python Script

Nov 19, 2012

How can i get device information from nonrooted device with python script? As I understand python don't have API like in Java.

I need to get system information from device, such as cpu frequencies, gpu vendor and other (like in Antutu and another benchmarks).

I know how to write python script with $getprop information from shell, and from buil.prop file in the system files, but it isn't enough. I also know how to get these information with shell command and busybox installed, but I shouldn't root them.

Android :: How To Compress Data To Obtain Same Value In Python?

Mar 11, 2010

I am porting a Python application to Android and, at some point, this application has to communicate with a Web Service, sending it compressed data. In order to do that it uses the next method:
def stuff(self, data): "Convert into UTF-8 and compress."
return zlib.compress(simplejson.dumps(data))

I am using the next method to try to emulate this behavior in Android:
private String compressString(String stringToCompress) { Log.i(TAG, "Compressing String " + stringToCompress);
byte[] input = stringToCompress.getBytes();
// Create the compressor with highest level of compression Deflater compressor = new Deflater();
// Give the compressor the data to compress compressor.setInput(input); compressor.finish();
// Create an expandable byte array to hold the compressed data.
// You cannot use an array that's the same size as the orginal because
// there is no guarantee that the compressed data will be smaller than
// the uncompressed data.
ByteArrayOutputStream bos = new ByteArrayOutputStream(input.length);
// Compress the data byte[] buf = new byte[1024];
while (!compressor.finished()) { int count = compressor.deflate(buf);
bos.write(buf, 0, count); } try { bos.close();
} catch (IOException e) { } // Get the compressed data byte[] compressedData = bos.toByteArray();
Log.i(TAG, "Finished to compress string " + stringToCompress);
return new String(compressedData);
But the HTTP response from the server is not correct and I guess it is because the result of the compression in Java is not the same as the one in Python. I ran a little test compressing "a" both with zlib.compress and deflate.
Python, zlib.compress() -> x%9CSJT%02%00%01M%00%A6
Android, Deflater.deflate -> H%EF%BF%BDK%04%00%00b%00b
How should I compress the data in Android to obtain the same value of zlib.compress() in Python?

Android :: Starting - Java Or Python - SL4A

Jul 27, 2010

I just ordered an Android smartphone and want to start playing around with creating my own applications. Now the question is which language to use, the native Java or Python using SL4A (former ASE).

I tend to Python, as I know it much better than Java, but I'm wondering what I would be missing using a "second class" language on Android. On the SL4A website it is also stated to be alpha quality software, which is not exactly encouraging.

I'm also not quite sure what the limitations of the scripting environment are and if they would be problematic.

Android :: Making Python Service To Run In Suspend State

Jan 16, 2010

Here's my Python script written using android-scripting:


while True:


It basically vibrates every minute (like a motivator). However, when the phone is locked with screen blanked out, I don't sense any vibration. Perhaps Android is freezing the script (and hence the while loop)? Note that I am indeed running this script as a service (long-tap and click 'Start as service').

Is there a way to make this script work all the time regardless of the phone suspend state?

Update 1: I do hear the vibration occasionally, not every minute .. but rather like every 5-10 minutes randomly.

Update 2: This problems occurs if I run the script normally (not as a service). Seems like "time.sleep" is not sleeping for the specified time.

General :: (SL4A) Importing PHP Or Python Script From Github To Execute From Command Line

Jun 1, 2013

What I am trying to do is get either nest-api in PHP or pynest in python to run out of SL4A in order to control my Nest thermostat ultimately out of Tasker. Both are found on github, but I can't link to them as I apparently need ten posts to do so. So a google search for "nest-api github" and "pynest github" will have to do I suppose.

I have absolutely no issues getting either to run out of Terminal on my MacBook Air, but for whatever reading the SL4A shell seems to escape my understanding. I would rather have the PHP script work, as it has more options for things I can set, which I like. Where to put the nest.class.php on my phone in order for the PHP shell to reference it when running the example.php or any script I write myself. When I put both files in the sdcard/sl4a/scripts folder and try to run either from within either sl4a or sl4a's shell I get a call to undefined function error.

For the python script, I'm not sure how I need to import the module so that I can call it with at the beginning of my command line prompt and follow it up with the user name and password and so on. I've done everything including trying to create an .egg file, which I've since been told is not necessary, and that I simply have to put it in the /sl4a/scripts folder. That doesn't make sense to me though, as I needed to run the command on my computer in order to start using it, and the .egg file should be the equivalent of that on the phone, no?

So what I am looking for is the foolproof way to get either a php or python script running through the shell that isn't actually hooking into the Android environment at all, which is what all the writeups I have found in my searching seems to pertain to. Then eventually make sure that they are available in a way that Tasker can call them. I should also note that all this has been done in an emulator through eclipse until this point, as I didn't want to go screwing around with my brand new Nexus 4's file structure until I had the best practice perfected.

Android :: Difference Between Sha224 And Python Sha224

Nov 15, 2010

Hello Everybody. For an application prototype I'm creating a simple user login. The Password of the user will then be hashed using sha224 and transferred to the back-end. The Problem I am facing right now is the following. The password that was stored in the DB (also hashed using sha224) seems to look a little different then the hash I am sending.

I use the following code to create the hashes.


What now will be produced looks like this and I will post the two hashes directly underneath each other. (The first one is python and the second android)


They are almost the same but the python hash has two 0s more. Do you guys have any idea why?
