this has probably to do with Issue 12

I would appreciate if you could try the version attached to Issue 12

I'm still getting a white screen after the update.

[GoogleCodeExporter]

did you try the version attached to issue12 or the update from the market?

ah and could you provide me the output of "adb logcat"? a tool that is part of 
the 
android SDK. (Can be found in the tools folder)

I'm not a developer so I'm not sure I have access to those tools. I'm just a 
huge fan of AR. I tried both 
the version from issue 12 and the update from the market which seemed to have 
the same 
result....blank white screen. I wish I could be of more help... good luck.

I have a Droid with 2.1 using the apk attached to issue 12, and am experiencing 
the same white screen as well. 
The logcat is attached here.

thanks for the log!
maybe it has to do with that:
http://code.google.com/p/android/issues/detail?id=5514#c0

I commented out the parts changing the preview size. Could someone try the 
attached apk?
Could furthermore someone tell what the getSupportedPreviewSizes method of the 
camera parameters returns on the 
droid?
This can be done like this:
[code]
Camera.Parameters params = camera.getParameters();
List<Camera.Size> list = params.getSupportedPreviewSizes();
[/code]
I'm interested in the contents of this list. I would really appreciate that! :D

Hi, I have a Motorola Droid with 2.1 and the white-screen crash bug mentioned 
above.

Calling getSupportedPreviewSizes() on my phone gives a list of 7 preview sizes:

176x144
320x240
352x288
640x480
720x480
720x576
848x480

The .apk file posted above does not fix the problem, unfortunately.  Hope the 
list is
helpful!

Thanks!

i commented out:

Parameters params = camera.getParameters(); 
                                //try to set the preview size to this fixed value
                                params.setPreviewSize(240,160);
                                try {
                                camera.setParameters(params);
                        } catch(RuntimeException ex) {
                                ex.printStackTrace();
                        }

then just set my preview size like so:

params.setPreviewSize(320,240);

and no longer have a white screen on my Droid w/ 2.1.

Granted this isn't the best way to set the size, but it's working :)

Interesting Nikko. So does that mean that Droid does not support a preview size 
of
240x160?  

In one of my earlier tests on N1 I also used a larger preview size, I chose one 
that
had the same aspect ratio as 240x160, and it seemed to work well. 

Original comment by suzy...@gmail.com on 22 May 2010 at 3:38

[GoogleCodeExporter]

Correct. The Droid supports the sizes listed in comment #9, from elm19087. The
supported resolutions are hardware dependent, which would explain why 240x160 
works
for your N1.

Hi nikko.aiello,
thanks for testing.
Am I getting this right, with a preview size of 320 x 240 everything works fine?

elm19087 tested a version where all setParameters were commented out. In that 
case the 
camera should use the default preview size, which should be one that is 
supported. 
however that version did not work.

I'm going to write a version that queries the available preview sizes, and sets 
one that 
fits best. The problem is that there are no functions to query those sizes on 
Android 
1.6. So this is no a trivial task, when you don't won't to raise an VerifyError 
on those 
phones. 

Furthermore there not all framerate previewsize combinations are supported. You 
can not 
query the framerates supported by a preview size or vice versa.

alright, I circumvented the the verfiyerror using reflection. I uploaded the 
sources to 
the SVN repository. (r139)
The app now queries the available previewsizes /formats and chooses one that 
fits best.
Could one of you milestone guys try out, if that works on your phones?
Thanks in advance ;)

I was able to build from r139 and install onto my Motorola Droid running 2.1, 
where it no longer has the white 
screen. I pointed the camera at the printed marker and saw a green cube 
positioned as expected. Yee-haw! AR 
on the Droid! Thanks to you & all contribs! I've attached a logcat from one of 
my runs in the hopes that it will be 
of use going forward.

A white screen appears also in the HTC Magic (Android 1.6)
It's something about camera parameters? Thanks

[GoogleCodeExporter]

alright, thanks for testing pat.dalberg. Thanks is indeed great news!

@leiret which version of AndAR are you using? A dedicated issue might be good. 
Do you 
know how to provide the output of logcat?. 

It seems to work on the HTC magic with android 1.5,.. strange.

Original comment by tdomhan on 27 May 2010 at 7:40

[GoogleCodeExporter]

right, the unfortunate thing about 1.6 is that it doesn't offer the preview 
sizes.
maybe have a list of optimal sizes, and iterate through it until one sticks??

Original comment by nikko.ai...@gmail.com on 28 May 2010 at 6:28

[GoogleCodeExporter]

well it works on HTC Magic with Android 1.5, I don't think the preview sizes 
have 
changed with the version upgrade.
the output of logcat would be nice. Can you provide that?

Original comment by tdomhan on 1 Jun 2010 at 8:58

[GoogleCodeExporter]

Here is the output of logcat.
The andar.jar is of date 24/04, and the AndObjViewer is the latest version.
HTC Magic, android 1.6
