hi

i have uploaded yesterday my latest b4a app and i saw some crash reports that are not very clear to me.

it seem for me like someone tried to run my app on a emulator, could that be?
i know that my app cannot run on a emulator because a lib (or more) does not iclude an x86 library.

is this the case?

thanks, ilan

btw those are the libs that i use:

It looks like an error related to DoEvents or a modal dialog.

hi,

but i have no doevents or modal dialogs in my code.
i use only the non modal dialogs: https://www.b4x.com/android/forum/t...cated-and-async-dialogs-msgbox.79578/#content

but it could be that there is a doevent in a lib, right?

 

[Erel]

It is possible. There is no such calls in any library created by Anywhere Software.

Not completely OT:

how do you interpret that log?

I do not see an "error", "exception" or similar; it looks like a series of normal logs, to my profane eye!

 

[Erel]

This is a low lever error so it is more difficult to extract useful information from it.

The "native message queue, poll once" suggests that it is related to DoEvents or modal dialogs.

It is similar to this error: https://www.b4x.com/android/forum/t...rnal-keyboard-causes-crash.71826/#post-456577 (and others as well).
