streitho / jythonroid Goto Github PK

What steps will reproduce the problem?
1. Download and install Android Emulator 5554 on Ubuntu Hardy 64
2. Download Jythonroid-0.3 and attempt install like so:

JiggityJog:~/android-sdk-linux_x86-1.0_r1/tools$ ./adb install
/home/doug/Jythonroid/bin/Jythonroid.apk 
1068 KB/s (1489190 bytes in 1.360s)
        pkg: /data/local/tmp/Jythonroid.apk
Failure [INSTALL_PARSE_FAILED_MANIFEST_MALFORMED]

3. Fill out this form. :-) 

What is the expected output? What do you see instead?

Failure [INSTALL_PARSE_FAILED_MANIFEST_MALFORMED]

What version of the product are you using? On what operating system?
0.3, Ubuntu Hardy 64 (tried on Intrepid as well )

Please provide any additional information below.

Let me know how I can help.

I realise the project is dead so this doesn't help, but:

Android scripting is not a proper replacement for jythonroid.

Jythonroid would have allowed us to make python apps and put them on the 
marketplace, with android scripting people need the ASE installed, this is a 
barrier to writing python apps and putting them on the marketplace. 

Just wondering.. If not I'll look elsewhere for jython for android (which
seems like a jolly good idea if you ask me).

What steps will reproduce the problem?
1.copy the fold Lib and caches into android:/data/data/org.python.util/ 
2. modify the PySystemState.java in 301, force the parament 'root' to be
"/data/data/org.python.util"
3. copy the .class files into the Jythonroid.apk, then install it.
4.run dalvikvm -classpath /data/app/Jythonroid.apk org.python.util.jython

What is the expected output? What do you see instead?
expected to run successfully, but instead throws Exception like bellow:

error importing site
Traceback (innermost last):
  File "/data/data/org.python.util/Lib/site.py", line 68, in ?
AttributeError: module 'sys' has no attribute 'modules'

Please use labels and text to provide additional information.

It seem like that the Jythonroid will use the .class files and, and then
initialize the sys module there.

so i decide to make two branches of my code, one is Jythonroid-server, the
Other is Jythonroid-client.
the Jythonroid-server will be compiled into a jar file ,and then install in
/data/data/org.python.util, and the fold contains py files (Lib) will move
here too.
the Jythonroid-client will be a Android project, and will have the code
org/python/util/Jythonroid.java

1.>>>from android.app import * will not work 
2.>>>from android.app import Activity works fine

by compareing the jython running in sunjvm and dalvik, i find that in
dalvik it is the JavaImportHelper that handling the import of the package.
and it's said in the comment that:

    /**
     * Try to add the java package.
     * <p>
     * This is handy in cases where the package scan cannot run, or when
the initial classpath does not contain all .jar
     * files (such as in J2EE containers).
     * <p>
     * There is some self-healing in the sense that a correct, explicit
import of a java class will succeed even if
     * sys.modules already contains a Py.None entry for the corresponding
java package.
     * 
     * @param packageName The dotted name of the java package
     * @param fromlist A tuple with the from names to import. Can be null
or empty.
     * 
     * @return <code>true</code> if a java package was doubtlessly
identified and added, <code>false</code>
     * otherwise.
     */

and the exception is throwed by the 
                String parentPackageName = packageName;
                if (isLoadedPackage(packageName, packages)) {
                    packageAdded = addPackage(packageName, packageAdded);
                }

>>>import sys
>>>sys.__dict__
Traceback (innermost last):
  File "<console>", line 1, in ?
AttributeError: module 'sys' has no attribute '__dict__'

seems like the sys module is not initialize correctly, so the other part of
the program will not be able to access sys.path.__classpat__.

the sys module is defined in PySystemState.java

(Using the 16-Nov-2008 build.) This makes it difficult to use
interactively...  is there any trick to get around this?  Or are we stuck
until the edit box works?

(What I *actually* want is to be able to write standalone applications with
this - even if that means embedding jython in them - maybe having the
default app use a little python code to display something, which we could
then extend and rebuild?)

Thanks...

Hi,

It seems my code cannot read an apk File I have created on the Android 
emulator.

- First off, I created an sdcard with command 'mksdcard ...'
- then I run this code: 

------------- Begin Cut Here --------------->

File tmpdir = new File(tmpdirpath+name);

if (!tmpdir.exists()) 
 {
  boolean b = tmpdir.mkdirs();
 } 
else
 {
  if (!tmpdir.isDirectory()) 
   {
    throw new RuntimeException("here : the tmp dir conflicts");
   }
 }
File apk = new File(tmpdirpath + name + "/" + name + ".apk");
if (!apk.exists())
 {
  apk.createNewFile();
 }
// with name = name of my apk file.

------------- End Cut Here --------------->

- The apk file is successfully created on a temporary directory on /sdcard,
but I have no permissions to read it: 

- - - - r w - r w -

- I tryed to change them:
#adb shell
# chmod 777 myFile.apk

No error but permissions remain the same  

- - - - r w - r w -

and I get the following exception:

Can somebody help please?

Hi, 
  Thanks your great job for porring jython.
  From the code, you used DexFile to generate apk and load class.
  I think it is not necessary to do this. 
  If develop jython as a service, when run the service all the class will
be loaded by system automaticly?

  Does my understanding is right?

  If you are in China, could you contact me?

  My msn  [email protected]
  Thanks. 

Huadong

we will need to make the jython access the python lib files that compressed
in the Jythonroid.apk file.
