Ice Cream Sandwich

[Adam Pigg]

Hi

When i deploy onto an ICS device, either my sons tablet, ZT280-C71, a
HTC Sensation or SGS2, the app crashes.

The only device i have access to is the tablet, and i get this message
running from the debugger:

E/dalvikvm( 1349): JNI ERROR (app bug): accessed stale local reference
0x1d200001 (index 0 in a table of size 0)
E/dalvikvm( 1349): VM aborting

Any ideas? Ministro downloads all the libs, but maybe ICS is not supported?

Cheers

Adam

it is, my app works fine, must be sth else.

What api do you compile with?

I was using api-10, but im installing api-14 now to see if that helps.

Cheers

11 and 12 (IIRC even 8)

hmmm, no joy with api-14..same problem as api-10.

here is the full output, incase anyone can suggest something (most of
the stuff at the end is my own debug output)

yeah, your right.....i was getting to that, im kinda multi-tasking,
browsing opengameart.org for some better graphics for another project,
and running through a conceptual stage in my head for something
new....in any case, this is how the lazy-web works :)

Thanks, i'll read through that page

Marco (and anyone else)

Tell me if im being lazy again, but...

It seems i need to register some variables with the garbage collector?
if so, this requires accss to the JNIenv...ive no idea what this is,
but ive read that i can get access to it by modifying
qtmain_android.cpp?

Is this the best solution?

Thanks (qt im familiar with, android and java, not so!)

Adam

[Marco Bernasocchi]

Hi I've no idea :) but iirc bogdan said that qtmain-android was going to disappear in alpha 4?

Ciao

It is gone, I just pushed Taylor's patch moments ago.

Cheers,

[Marco Bernasocchi]

Hi BogDan
Thanks a lot!
What would i have to do to try out all the latest code with my app? Are the unstable repos in ministro delivering the latest code? Ciao

Ps was it correct that qtmain-android will go away? How will it be replaced?

[Adam Pigg]

hi Bogdan, any idea how to fix my bug, or will i just have to start commenting out code until i find it? What is the new way to get access to the jnienv?

Hi,

No, not yet, I still have a few things missing.
Anyway it should be 100% compatible with alpha3 unless you didn't
change any private files (e.g. qtmain-android) or used any private
java classes directly.

Cheers,
BogDan.

I may be making progress tracking something down....i basically
commented out everything in my C++ side to start enabling things one
at a time, but found it odd that i was getting debug messages from
code that wasnt even compiled, even after a clean/build cycle!

Then, i deleted the build dirs, no change.

Then i deleted the android/bin and android/libs dirs, rebuilt, and now
its executing the code it should be..so i may have more chance of
debugging it, if not, i may take you up on your kind offer of a
debugging service ;)

[Adam Pigg]

Well

That is annoying!

Ive spent hours disabling/enabling code and adding debug messages.
And now my app pretty much works....with all the original code
enabled!

At one point, im sure adding a debug message made it run!

Ive now got 2 seemingly clear cases where i get the JNI error:
1) When i call Qt.quit() in QML
2) When i call acceleromenter.stop() in QML

so i commented out 2), and ignore 1) as its not noticable, when you
quit, it crashes :)

Hopefully i will find out more!
