Hello huberte, so you reported that the menu and other things crash in
some devices, right?

I just tested here in Galaxy S 2 with Android 2.3 and the menu works
fine.

I know that there is a crash in Galaxy Nexus with Android 4 which I am
tracking.

So, could you clarify the following points:

1> Which Android version does you Galaxy S2 have?
2> With which devices and which instructions exactly does it crash?
3> Does it also crash with the example application from
examples/androidtest or only with your app? Maybe you are not
syncronizing correctly the changes the the .java file.

1. Mine is a SGS2 2.3.6, the one where the menu crashed is a 4.0 SGS2,
it crashed too on HTC wildfire. Do you know why it wont install on a
2.1.1 Android ?
2. Same as above and crashes too with the example application. the
menu button for example crashes too, I'll ask for other things.

what did you see in the logcat ?

Ok, so this is known. They changed something in Android 4.0 and there
are issues with it.

I have an idea. I think that I need to stop the pre-calculation of JNI
IDs and calculate them everytime in each routine. It could solve the
problem (or not). It solved a similar problem some time ago.

Is this Wildfire using Android 2.1? LCL-CustomDrawn-Android requires
Android 2.2 There is no way to make it work in Android 2.1 since it
lacks a lot of APIs that I use.

Notice that Wildfire is upgradable to 2.2

If the problem is only Android 4.0 then I can reproduce here too and I
can see my own logcats. I still need to invest more time in this to
investigate the cause.

Ok, I fixed all errors which I could find for Samsung Galaxy S2 with
Android 4.0 in rev 37245 and then further improved for Galaxy Nexus S
4.0 in rev 37246

Please test again =)

JNI is quite tricky. I had some small errors and missunderstandings
which worked fine in older versions but broke now. Now the VM seams
more strict.
