Inconvenienced when using Contact Content Provider on Android
These days, I've been developing an application that reads and writes entries from/into Android Contacts.
Everything goes fine until I need to insert email entry into Android Contact by Contact Content Provider API.
This is how to insert a people or phone entry into contact (people, phones table):
getContentProvider().insert(People.CONTENT_URI, values);
getContentProvider().insert(Phones.CONTENT_URI, values);
That's fine according to
http://code.google.com/android/devel/data/contentproviders.html
However when I insert an email entry into contact (in contact_methods table) using:
ContentURI uri = getContentProvider().insert(ContactMethods.CONTENT_URI, values);
It just returns null, nothing inserted, and nothing shows up on logcat.
Why? the link above says it should be fine!
To find the answer, I post a thread in Google Group:
http://groups.google.com/group/android-developers/browse_thread/thread/9ed4ff7fc1338b7c
However no response.
then I have been diving into build-in Contacts Application for 2 days to find how Google used their own api.
Luckily, I got the key.
see details on my another post:
http://zeaster.blogspot.com/2007/11/how-to-decompile-dex-file-on-android_28.html
You should insert an email like this:
ContentURI uri = People.CONTENT_URI.addId(user_id).addPath("contact_methods");
ContentValues values = ...
uri = getContentResolver().insert(uri, values);
why? I guess Google should provide one same way to insert content.
That's the main inconvenience.
I guess what's even worse is Google does not provide enough docs or log warnings for this tip.
Here are the others:
2.
when insert an email for a not-created-yet user id, It's still inserted successfully.
when the user id created in the future, the user would have the email address.
I guess Google should prevent this happen.
Actually many checks Google need to do.That's really a beta SDK.
3.
The content provider API is not Object-Oriented enough.
I feel it tedious to use.
4.
Maybe this is greedy.
I hope there is API to manipulate database that's similar to ActiveRecord for Rails.
Maybe I will implement one like that if time permits.
How to decompile .dex file on Android
Lucky to see the Google Android build-in Contacts is also developed by Android SDK.
This article will take it for example and discuss these How-To's:
1 How to find the Contacts App file on Google Android
2 How to find the Contacts App's classes.dex on Google Android
3 How to dump the Contacts App's classes
4 How to decompile the dumped file
{
Actually, I think the Contacts Content Provider that Google provides has some inconvenience to use.
And I will post another blog to list what's inconvenience and request some improvement from Google.

The Contacts.apk is the Contacts App and ContactsProvider.apk is the app that provides the Contact Content Provider for reading and writing "content://contacts/" resources.
we can see many system apps developed by Android Java SDK are put here.
However what is inside *.apk file. Actually it is a .zip file. It is easy to unzip and get the answer.
take Contacts.apk for example, it contains:
META-INF\
res\
AndroidManifest.xml
classes.dex
resources.arsc
The classes.dex file contains all compiled Java code.
2 How to find the Contacts App's classes.dex on Google Android
No need to unzip Contacts App's classes.dex file from Contacts.apk file.
The Dalvik VM has a cached file for us. Go head to find it.
$ adb shell
# cd /data/dalvik-cache
cd /data/dalvik-cache
# ls
ls
-rw-rw-rw- root root 73852 2007-11-27 05:16 system@app@Contacts.apk@classes.dex
-rw-rw-rw- app_0 app_0 64172 2007-11-27 05:17 system@app@ContactsProvider.apk@classes.dex
-rw-rw-rw- root root 15204 2007-11-27 05:17 system@framework@am.jar@classes.dex
-rw-rw-rw- app_3 app_3 3012 2007-11-27 07:33 system@app@Fallback.apk@classes.dex
-rw-rw-rw- root root 7252804 2007-11-27 05:16 system@framework@core.jar@classes.dex
....and many other cached files.
3 How to dump the Contacts App's classes
Unfortunately the classes.dex is not a .jar file. It's Dalvik executable format that is optimized for efficient.
so we can not pull the .class files as .jar format. However Google Android provides a tool named dexdump included in the emulator to dump .dex file. Here is how to use it.
# dexdump
dexdump: no file specified
dexdump: [-f] [-h] dexfile...
-d : disassemble code sections
-f : display summary information from file header
-h : display file header details
-C : decode (demangle) low-level symbol names
-S : compute sizes only
Now we dump the system@app@Contacts.apk@classes.dex and system@app@ContactsProvider.apk@classes.dex.
# dexdump -d -f -h -C system@app@Contacts.apk@classes.dex >> Contacts.apk.dump
# dexdump -d -f -h -C system@app@ContactsProvider.apk@classes.dex >> ContactsProvider.apk.dump
and then pull it out.
# exit
$ adb pull /data/dalvik-cache/Contacts.apk.dump ~/android
$ adb pull /data/dalvik-cache/ContactsProvider.apk.dump ~/android
Now we get the dumped files on ~/android folder.
4 How to decompile the dumped file
.dex file is optimized, so we can not decompile it as normal .class file.
Fortunately the dumped file is a bit readable for me.
As it is too big to analyze all the code, so I just take "how to create a contact" for example.
It's easy to get this info from the dumped file.
It has these classes:
...
Class name : 'com/google/android/contacts/AttachImage'
Class name : 'com/google/android/contacts/ContactEntryAdapter'
Class name : 'com/google/android/contacts/EditContactActivity'
Class name : 'com/google/android/contacts/EditContactActivity$EditEntry'
...
The EditContactActivity class has a private void create() method.
#3 : (in com/google/android/contacts/EditContactActivity)
name : 'create'
type : '()V'
access : 0x0002 (PRIVATE)
So all the code that create a contact is here from the dumped file, my comments inlined:
// private void create()
009b24: |[009b24] com/google/android/contacts/EditContactActivity.create:()V

how to add jdk bin path in path environment?
- windows
- says your java.exe is in directory c:\jdk1.5.0\bin
- set the following line in run.bat
set path=c:jdk1.5.0bin;%path%
- Mac or unix
- says your java is in directory /path/to/your/java
- set the following line in run.sh
export PATH=/path/to/your/java:$PATH
how do I know which version of jdk I am using?
open a terminal, type "java -version". you should get something like this:
java version "1.5.0_12"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_12-b04)
Java HotSpot(TM) Client VM (build 1.5.0_12-b04, mixed mode)
how to run run.bat/run.sh in command line?
- windows
- Mac or unix
open a command window, type:cd e:pathtoyourrun.bat
run.bat
open a terminal, type:cd /path/to/your/run.sh
sh run.sh
when run run.sh, it is opened by my editor, what should I do?
please run run.sh in command line.
after clicking on run.bat/run.sh, there was nothing happend, what should I do?
run run.bat/run.sh in command line so that find what's going wrong in the terminal?
It prompts "java: command not found", what's going wrong?
java is not in your path, please add jdk bin path in your path environment.
why do I get Exception in thread "main" java.lang.NoClassDefFoundError: org/easter/blogsync/BlogSync?
if you are on Mac or unix, please make sure you have read permission on blogsync/build/blogsync.jar file if not, open a terminal and type:
chmod 744 /path/to/your/blogsync/build/blogsync.jar
why do I get Failed to create input stream: Server returned HTTP response code: 403 for URL: http://mydomain.com/wordpress/xmlrpc.php?
- if you installed a plugin called Enforce www. Preference, it would affect the path to your xmlrpc.php file, so deactivated it first.
- if you enabled mod_security on apache, it would block access to xmlrpc.php, so add this to your .htaccess file:
<Files xmlrpc.php>

python script to email me the dynamic ip from tp-link router
At home, my boxes are connected to internet by Beijing ADSL.
when connected, Beijing ADSL gives me a dynamic ip and it changes about every 24 hours.
Before I get the dynamic ip by a service provided by oray.net.
However recently the service is broken.
So I have to write a python script to check the dynamic ip from my tp-link router every 3 minutes and if it changed, emails the new dynamic ip to my gmail.
I also write a bash script to run the above python script at boot on my gentoo linux.
The python script:
#!/usr/bin/python
import urllib
import urllib2
import libgmail
import cookielib
import sys
import re
import base64
import socket
import time
from urlparse import urlparse
nowip=''
logfile=open('/var/log/ipsender.log','w')
def log(s):
now=time.strftime('%Y-%m-%d %X')
logfile.write('%s %sn'%(now,s))
logfile.flush()
def gmailsender(to_addr,subject,msg):
username='xxx@gmail.com'
password='xxx'
ga=libgmail.GmailAccount(username,password)
ga.login()
gmsg=libgmail.GmailComposedMessage(to_addr,subject,msg)
ga.sendMessage(gmsg)
def check():
global nowip
timeout=10
socket.setdefaulttimeout(timeout)
username = 'admin'
password = 'xxx'
try:
theurl='http://192.168.1.1/userRpm/StatusRpm.htm'
req = urllib2.Request(theurl)
base64string = base64.encodestring('%s:%s' % (username, password))[:-1]
authheader = "Basic %s" % base64string
req.add_header("Authorization", authheader)
handle = urllib2.urlopen(req)
str=handle.read()
ss='var wanPara = new Array'
start=str.index(ss)+ss.__len__()
end=str.index(';',start)
s2=str[start:end]
log(s2)
t=eval(s2)
log(t[2])
handle.close()
if nowip!=t[2]:
nowip=t[2]
gmailsender('mygmail@gmail.com','ddnsip===%s'%nowip,s2)
log('send %s successfully.'%nowip)
else:
log('ddnsip remains %s.'%nowip)
except:
log('Unexpected error:', sys.exc_info()[0])
def main():

time.sleep(3*60)

}wake-on-lan by python script
How to wake up your computer on the LAN?
the answer is just to send a Magic Packet to your computer on port 7 or 9.
However when your computer is down, it has no ip, so send it to the broadcast ip
the following python script implements the above idea.
import struct, socket
def wake_on_lan(ether_addr, inet_addr):
addr_byte=ether_addr.split(':')
hw_addr=struct.pack('BBBBBB',
int(addr_byte[0],16),
int(addr_byte[1],16),
int(addr_byte[2],16),
int(addr_byte[3],16),
int(addr_byte[4],16),
int(addr_byte[5],16))
msg='\xff'*6+hw_addr*16
s=socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)
s.sendto(msg, (inet_addr,7))
s.close()
wake_on_lan('00:E0:4C:E1:D9:CC', '192.168.1.255')
The code above is based on socket.SOCK_DGRAM to send UDP packet.
How to create a UDP packet based on raw socket in python?
the project dpkt does an excellent job.
the following example shows that:
import socket
from dpkt import ethernet,udp,ip
import dpkt
import struct
import string
iface = "eth1"
mac = "00:0E:35:AB:9B:40"
inet = "192.168.1.6"
debug = 0
def eth_aton(buffer):
addr =''
temp = string.split(buffer,':')
buffer = string.join(temp,'')
for i in range(0, len(buffer), 2):
addr = ''.join([addr,struct.pack('B', int(buffer[i: i + 2], 16))],)
return addr
def buildUdp():
ether_addr='00:E0:4C:E1:D9:CD'
addr_byte=ether_addr.split(':')
hw_addr=struct.pack('BBBBBB',
int(addr_byte[0],16),
int(addr_byte[1],16),
int(addr_byte[2],16),
int(addr_byte[3],16),
int(addr_byte[4],16),
int(addr_byte[5],16))
msg='xff'*6+hw_addr*16
udp_p = udp.UDP()
udp_p.sport = 0x8130
udp_p.dport = 7
udp_p.data = msg
udp_p.ulen += len(udp_p.data)
ip_p = ip.IP()
ip_p.src = socket.inet_aton('192.168.1.6');
ip_p.dst = socket.inet_aton('192.168.1.255');
ip_p.off = 0x4000
ip_p.data = udp_p
ip_p.p = ip.IP_PROTO_UDP
ip_p.len += len(udp_p)
packet = ethernet.Ethernet()
packet.src = eth_aton(mac)
packet.dst = eth_aton('ff:ff:ff:ff:ff:ff')
packet.data = ip_p
packet.type = ethernet.ETH_TYPE_IP
if debug: print dpkt.hexdump(str(packet))
return packet
s = socket.socket(socket.PF_PACKET, socket.SOCK_RAW)
s.bind((iface,ethernet.ETH_TYPE_IP))
packet = buildUdp()
s.send(str(packet))blogsync 0.3 released, comments can be imported.
Firstly, the foregoing blogsync 2.0 should be blogsync 0.2. :-)
blogsync is a tool that import your wordpress to blogger from rss xml file or online
Now it's blogsync 0.3 release. and it can import comments from exported wordpress rss xml file to blogger site.
it can be downloaded from:
http://code.google.com/p/blogsync-java/downloads/list
however it can not preserve the published time of the original comments.
so the published time of your imported comment is just the time when you import.
more details can be found at
http://groups.google.com/group/bloggerDev/browse_thread/thread/15c9a45416305f99
blogsync 2.0 released, import your wordpress to blogger from rss xml file or online
It's open source now and comes with new feature.
1 project hosted:
at http://code.google.com/p/blogsync-java
blogsync 0.2 can be downloaded at
http://blogsync-java.googlecode.com/files/blogsync-0.2.zip
2 new feature:
In previous blogsync, it imports wordpress posts to blogger from your wordpress website online.
Now in blogsync 0.2, it can import wordpress posts to blogger from a rss xml file that exported by wordpress.
when blogsync 0.1, the common errors are such as:
a)[Fatal Error] :1444:21: Invalid byte 1 of 1-byte UTF-8 sequence.
org.apache.xmlrpc.client.XmlRpcClientException: Failed to parse
servers response: Invalid byte 1 of 1-byte UTF-8 sequence.
b)Fatal Error] :1:1: Content is not allowed in prolog.
this is because
a) the server response is not in utf-8 encoding. or
b) the server response is not a valid xml.
when your posts are too big, for example, http://i978.iyublog.com, when export all of this blog's posts, the exported rss xml file is 2064KB.
so when transferring these data through http online, the above errors are easy to reproduce.
Few days ago, I tried to export all posts to a rss xml file, then imports these posts locally from the exported xml file, the above error is hard to reproduce again.
the worst case is that your export file is still invalid xml file or wrong encoding, however it's easy to find these errors and you can try to export it again or edit it manually until you get a valid utf-8 xml file. Now you can import these posts to blogger from the valid utf-8 rss xml file by blogsync 2.0.
ps:
how to export your wordpress posts to a rss xml file?
in wordpress admin page, go to "Manage" page -> "Export" page, there is a link to export all of your posts.
ps2:
within 24 hours, Google allows us to submit at most 50 posts by googe data api.
so after 50 posts, the tool can not import any. only to wait for another 24 hours.
