"Unfortunately, ODK Collect has stopped"

Support
1

Hi,

I have a rather lengthy and complicated xml form (attached). I loaded it onto ODK Collect and it worked fine, but every time I try to open the blank form now, I get a message that says "Unfortunately, ODK COllect has stopped". Is this because the file is too large? Any advice would be appreciated.

Thanks!
Alison

Hi Alison,
I haven't run into that before. It always seems to be the programming on my side that causes the issue. I have had forms with over 3,000 fields go into odk collect and be ok. If you haven't already,try splitting it up a chunk at a time and see what is and isn't working.

The error of significance is:

E/AndroidRuntime( 3737): at java.lang.Thread.run(Thread.java:856)
E/AndroidRuntime( 3737): Caused by: java.lang.StackOverflowError
E/AndroidRuntime( 3737): at
dalvik.system.BlockGuard.getThreadPolicy(BlockGuard.java:140)
E/AndroidRuntime( 3737): at libcore.io.BlockGuardOs.read(BlockGuardOs.java:148)
E/AndroidRuntime( 3737): at libcore.io.IoBridge.read(IoBridge.java:422)
E/AndroidRuntime( 3737): at
java.io.FileInputStream.read(FileInputStream.java:179)

In particular, the "StackOverflowError" mentioned above -- Android has a
rather tight limit on the size of the "execution stack". This restricts
the complexity of expressions (relevant="...", calculate="...', etc.) that
you can use (the execution stack is used to remember where you are during
the evaluation of an expression). From other forms with similar problems,
it appears that this limits expressions to about 50 comparison tests.
Beyond that, you are increasingly likely to run into this
StackOverflowError.

In this case, it is highly likely that the relevant="..." condition for
'/iifipv_9152012/met/compvisit/iifcont/doipv/ipv/ipend"
is too complex to handle as-is.

An easy solution for this is to define one or more form fields that compute
a portion of the relevant condition. Then use those intermediate values in
the final relevant condition.

Juma,

I used a log capture tool on the phone (how to at
https://code.google.com/p/opendatakit/wiki/CollectTroubleshooting) and
saw this error.

E/FormController(32062): Only questions are allowed in 'field-list'.
Bad node is: /ibbss_fsw_french/gr1/gr901

I haven't looked closely, but it looks like your form has a group
gr901 that you open at line 22, but never close. Try fixing that and
see if that works better.

I've created a bug report for ODK Validate for this
http://code.google.com/p/opendatakit/issues/detail?id=973

ODK Validate should warn that this is a badly constructed form, but it does
not.
