Lots of people are posting helpful comments on the GetTheReader wiki,
but the list of comments is getting huge! It might be better to track
these as Issues, for bugs, or conduct as threads of discussion here.
Therefore I am "archiving" all the current comments here in this
thread, and posting a note asking people to conduct discussions here
and use the Issue tracker.

Just downloaded the deployed ZXingReader.jar and transfered it to a
K750i and Nokia 6300. The K750i terminates on startup with "Error in
application" without further information. The Nokia 6300 terminates on
startup with "Class Not Found java/lang/ClassNotFoundException? com/
google/zxing/client/j2me/ZXingMidlet".
Hope this helps to improve the program.
Kind regards from Dresden, Alex

Yeah the K750i doesn't support JSR-234. I will add it to the list of
phones that don't work at the moment. I am making a non-JSR-234
version too for people to try.
The 6300 is odd though since it claims it cannot even find the main
class. It could actually be reporting the wrong error due to another
similar incompatibility, I'm not sure.
I'll announce a version to try soon that may work on these devices.

It may install on the Nokia N95, however the N95 does not support
macro mode in JavaME, so it cannot focus properly on barcodes nor

Nokia N95 -- I'll have to test this. It definitely supports JSR-234
and has auto-focus, which seem like plenty to get it to work. But two
people have said they've had trouble.
To anyone that's testing on the N95: try taking a photo from farther
away to see if it works.
K510i -- yeah this does not support this JSR. I will shortly produce a
version that does not require, though I am not sure it will work as

About the Pearl "no init() method" error -- this could be a bug in how
I configured Proguard. It may be messing with the constructor; I can
adjust that. NoClassDefFoundError?: I bet this is because the pearl
doesn't support any of those media JSRs, right? it doesn't have a
camera so I bet it will not run.
I have a script that should properly build a client for the Curve,
but, it doesn't run. Lots of that going around it seems. :) If/when it
works I'll put that out. But as far as I know that's the only BB that

OK thank you. It does look like this phone should work for both

do not like that I've not tracked down yet. I'm puzzled it gives
different errors but maybe that is incidental.

Comment by digitalorion, Dec 14, 2007
I tried both versions the Basic and the normal version and both quit
at the logo screen. I guess there could be a problem with how the
program accesses the camera, maybe? I have tried other QR-Code readers
even the ones that say that support the LG CU500 (first edition) and
they don't work neither. However the application that came with my
phone for video phone/calling works great and it is also a java app.

Try setting "Multimedia" on the Permissions screen to "Ask Once". Not
sure if this is what you meant you tried or not. This will prevent it
from asking every time you take a picture, though you will have to
give permission once every time you start the app.
Do you grant it permission? if you don't, it will quit. Are you using
the basic or regular version? The W910i should support the regular
version, and I see it works on similar SEs, so I hope it does work for
you.

Thx for your reply.
Before I follow your instruction, it will popup and keep asking me
everytime. I click 'yes', then I can hear a sound (take photo effect),
and an error message popup said "Could not locate and decode a barcode
in the image."
Now, I follow your instruction, set the Permission to "No asking", now
it won't ask me anymore. However it still not working. A "Error"
popup, but there is no message in the middle of the screen. (#both
basic and normal version tested)
I would like to help if you want to do more test on w910i. Feel free

I tried with a K800i and get the "Invalid Application" for both the

on http://developers.sun.com/mobility/device/pub/device/list.do;jsessionid=6E0F8D2C06D5BB7F077946138642FBC9?filterIds=1007

FYI, I downloaded the jar on my PC and then transfered it onto the
device.

Z520a should work, at least according to its specs, so I am not sure
why it would not load. I will see if I can get my hands on this

devices I test on regularly. Try loading it over-the-air maybe?

Oops I meant the Z520a should work, but only with the "Basic" version.
Is that the one you are using? Since it doesn't appear to support

Just tried the standard version on a Nokia E70; no problems with the
installation but app didn't open at all. I uninstalled and downloaded
the basic version which seems to work but so far I was not able to
focus in enough on a barcode (UPC and 2D) to get it to recognize.
Getting some "Could not find three finder patterns" error and after
that the cam quadruples the picture. Nevertheless good work so far and
good luck!

Comment by srowen, Jan 12, 2008
Yeah the full version won't work since the E70 doesn't have JSR-234
(though Nokia makes their own very good reader for these phones.) Try
taking a photo from farther away and you may have some success, but,
you may do better with Nokia's application.

Comment by romin.k.irani, Jan 22, 2008
I have a Nokia 3500c. It does not support JSR-234 for sure. So I have
built the basic version for 0.2.1 and atleast the application starts
up fine. Now here are some very interesting observations: 1) Several
Nokia models including this one - 3500c - do not allow the
getSnapshot() method on capture://video. They throw back an exception
saying that getSnapshot is only supported on capture://image. So - the
application stalls there. 2) Now - what I did was the following: I
changed the code and built the basic version - this time with capture://image
instead of capture://video. Voila! No more issues with the getSnapshot
method now - however what happens is that the raw bytes returned are
null and I end up with a NPE. 3) It seems that if you pass null as a
parameter to getSnapshot(...) then the image is PNG format by default
(I am not an expert here - just some of my readings over the net). The
image/png is not supported by the 3500c among its
video.snapshot.encodings. 4) So the next thing I did was to find out
what are the video.snapshot.encodings supported on my device via the
System.getProperty. And it supports encoding=jpeg encoding=jpg
encoding=gif. Now even if I give this as a parameter to the
getSnapshot(..) - it still keeps returning null. So I am really stuck
over here and dont know how to proceed. 5) I tried to download a
compatible Kaywa Reader - there is no Kaywa Reader released so far for
the Nokia 3500c. So I did some reading on the net and found that Nokia
6280 too needs the capture://image instead of the capture://video. So
I 'intentionally' put the Kaywa Reader for 6280 on the 3500c and boom
- it works fine!! So what makes me wonder is how they are able to get
the image via getSnapshot(..) - am I missing something here.
Sorry for the long post - I wanted to give as much details as
possible.

Another update: I found a player.stop() call in the
SnapshotThread?.java class just before the
zXingMIDlet.getVideoControl().getSnapshot(...) method. Is this the
reason for getting a null for the byte[] snapshot variable.
I removed this statement and put it after the getSnapshot(...) method
and I dont get a null now.
Does this help?

Regarding the RAZR V3 question -- I doubt this library will support it
since we need CLDC 1.1 and the V3 only supports CLDC 1.0. Back-porting
it would be a little nasty (e.g. no floating point support!). The V3x,
I hear, might work, but I have not tested it.

For WinMo? -- hmm, it's unlikely we'll do that soon. While you can get

priority is to get to version 1.0, and then port to whatever mechanism
is needed for RIM BlackBerries?, and then the iPhone, and then maybe
WinMo?.

How about to add support, e.g. for test purpose, display taked picture

Delete comment
Comment by srowen, Today (51 minutes ago)
For the K850, I added a try-catch block to absorb and exception from
the call that sets the camera to FocusControl?.AUTO_FOCUS. This just
stops the auto-focus early so isn't vital. I checked in this change to
SVN. I am surprised that the K850 doesn't support this.
Yes I set the application permission to ask only once about taking the
photo. It is a bother. At least then you only have to confirm once on
the initial capture. Yes, this dialog typically causes me to not take
the picture correctly. Just try again -- does it work? This works well
on a K800 for me.
The application does pause and show you the image it captured for
decoding already.
If there are more issues could you open an item under the "Issues" tab

but, it doesn't run. Lots of that going around it seems. :) If/when it
works I'll put that out. But as far as I know that's the only BB that
will possibly run this.

The basic version run on my nokia E65 but when it comes to decode a
recognized qrcode, it says: "java.lang.ClassNoFoundException?: com/
google/zxing/qrcode/detector/DefaultGridSampler?"
(and no, this is not what is encoded in my code ;-) )

Try one more time? sounds like the regular version runs and almost
works. I just corrected a problem that was causing this class to be
removed. Try again?

The BREW-based Amoi WP-S1 (see Wikipedia) supports JSR-234 and runs
Kaywa Reader (a QR code reader with the same "supported devices" list)
more or less fine; the standard reader installs but when run quits
with "VM fatal error" and the Basic version comes up "907 Invalid
JAR". The device does not require JAR files to be signed

OK thank you. It does look like this phone should work for both
versions. It seems there is something about the build that some phones
do not like that I've not tracked down yet. I'm puzzled it gives
different errors but maybe that is incidental.

quits. no error given.

Can you try the "Basic" version? It looks like this phone does not
support JSR-234, but has a chance of running the Basic version. See

I tried both versions the Basic and the normal version and both quit
at the logo screen. I guess there could be a problem with how the
program accesses the camera, maybe? I have tried other QR-Code readers
even the ones that say that support the LG CU500 (first edition) and
they don't work neither. However the application that came with my
phone for video phone/calling works great and it is also a java app.

I bought w910i. It is not working, both version. The phone keep asking
for permission everytime when I click "5" (#the circle 'play/stop'

the cam. I have checked the permission page before I run zxing, there
is not pre-set which allow java to access the cam...

Try setting "Multimedia" on the Permissions screen to "Ask Once". Not
sure if this is what you meant you tried or not. This will prevent it
from asking every time you take a picture, though you will have to
give permission once every time you start the app.
Do you grant it permission? if you don't, it will quit. Are you using
the basic or regular version? The W910i should support the regular
version, and I see it works on similar SEs, so I hope it does work for
you.

Thx for your reply.
Before I follow your instruction, it will popup and keep asking me
everytime. I click 'yes', then I can hear a sound (take photo effect),
and an error message popup said "Could not locate and decode a barcode
in the image."
Now, I follow your instruction, set the Permission to "No asking", now
it won't ask me anymore. However it still not working. A "Error"
popup, but there is no message in the middle of the screen. (#both
basic and normal version tested)
I would like to help if you want to do more test on w910i. Feel free
to contact me by email. mac4work at gmail dot com. thanks

I tried with a K800i and get the "Invalid Application" for both the
basic and the advanced versions. I checked the device JSR support list
on http://developers.sun.com/mobility/device/pub/device/list.do;jsessionid=6E0F8D2C06D5BB7F077946138642FBC9?filterIds=1007
and it does show that a K800i supports JSR 234.
FYI, I downloaded the jar on my PC and then transfered it onto the
device.

Z520a should work, at least according to its specs, so I am not sure
why it would not load. I will see if I can get my hands on this
device. The K800i though should definitely work. This is one of the
devices I test on regularly. Try loading it over-the-air maybe?

Oops I meant the Z520a should work, but only with the "Basic" version.
Is that the one you are using? Since it doesn't appear to support
JSR-234 the regular version won't work.

Just tried the standard version on a Nokia E70; no problems with the
installation but app didn't open at all. I uninstalled and downloaded
the basic version which seems to work but so far I was not able to
focus in enough on a barcode (UPC and 2D) to get it to recognize.
Getting some "Could not find three finder patterns" error and after
that the cam quadruples the picture. Nevertheless good work so far and
good luck!

Comment by srowen, Jan 12, 2008
Yeah the full version won't work since the E70 doesn't have JSR-234
(though Nokia makes their own very good reader for these phones.) Try
taking a photo from farther away and you may have some success, but,
you may do better with Nokia's application.

Note it works on a Sony Ericsson k610i when you repair the manifest

I have a Nokia 3500c. It does not support JSR-234 for sure. So I have
built the basic version for 0.2.1 and atleast the application starts
up fine. Now here are some very interesting observations: 1) Several
Nokia models including this one - 3500c - do not allow the
getSnapshot() method on capture://video. They throw back an exception
saying that getSnapshot is only supported on capture://image. So - the
application stalls there. 2) Now - what I did was the following: I
changed the code and built the basic version - this time with capture://image
instead of capture://video. Voila! No more issues with the getSnapshot
method now - however what happens is that the raw bytes returned are
null and I end up with a NPE. 3) It seems that if you pass null as a
parameter to getSnapshot(...) then the image is PNG format by default
(I am not an expert here - just some of my readings over the net). The
image/png is not supported by the 3500c among its
video.snapshot.encodings. 4) So the next thing I did was to find out
what are the video.snapshot.encodings supported on my device via the
System.getProperty. And it supports encoding=jpeg encoding=jpg
encoding=gif. Now even if I give this as a parameter to the
getSnapshot(..) - it still keeps returning null. So I am really stuck
over here and dont know how to proceed. 5) I tried to download a
compatible Kaywa Reader - there is no Kaywa Reader released so far for
the Nokia 3500c. So I did some reading on the net and found that Nokia
6280 too needs the capture://image instead of the capture://video. So
I 'intentionally' put the Kaywa Reader for 6280 on the 3500c and boom
- it works fine!! So what makes me wonder is how they are able to get
the image via getSnapshot(..) - am I missing something here.
Sorry for the long post - I wanted to give as much details as
possible.

Another update: I found a player.stop() call in the
SnapshotThread?.java class just before the
zXingMIDlet.getVideoControl().getSnapshot(...) method. Is this the
reason for getting a null for the byte[] snapshot variable.
I removed this statement and put it after the getSnapshot(...) method
and I dont get a null now.
Does this help?

Regarding the RAZR V3 question -- I doubt this library will support it
since we need CLDC 1.1 and the V3 only supports CLDC 1.0. Back-porting
it would be a little nasty (e.g. no floating point support!). The V3x,
I hear, might work, but I have not tested it.

For WinMo? -- hmm, it's unlikely we'll do that soon. While you can get
a JVM for WinMo?, I don't think it will support the APIs needed to run
this code, so, it would involve porting the code out of Java. First
priority is to get to version 1.0, and then port to whatever mechanism
is needed for RIM BlackBerries?, and then the iPhone, and then maybe
WinMo?.
But there seem to be readers out there already:

Samsung U600: this will only run the Basic version. Does that work?

How about to add support, e.g. for test purpose, display taked picture
before decode?
Delete comment
Comment by srowen, Today (51 minutes ago)
For the K850, I added a try-catch block to absorb and exception from
the call that sets the camera to FocusControl?.AUTO_FOCUS. This just
stops the auto-focus early so isn't vital. I checked in this change to
SVN. I am surprised that the K850 doesn't support this.
Yes I set the application permission to ask only once about taking the
photo. It is a bother. At least then you only have to confirm once on
the initial capture. Yes, this dialog typically causes me to not take
the picture correctly. Just try again -- does it work? This works well
on a K800 for me.
The application does pause and show you the image it captured for
decoding already.
If there are more issues could you open an item under the "Issues" tab
above?
