Java Question SDK API Library works on android 4.0.4 but fails on 4.4.2

SDK API Library works on android 4.0.4 but fails on 4.4.2

Hi,
I use Simple Library Compiler to create an B4A library from an SDK API for a barcode scanner.
(with help last year from B4a Users, thank you)

But now the manufacture has upgraded the scanners, and gone to android 4.4.2
They gave me new libraries, and said, 'just copy into your lib folders' will work on 4.0.4 and 4.4.2
To test the new libraries they gave me, i first compiled in a test project in 'Eclipse', they work in android 4.0.4 and 4.4.2 !!!

Using Simple Library Compiler (SLC)
I copied the new files
cw-deviceapi.jar into /additional//lib
libDeviceAPI.so into /additional/lib/armeabi
seems to have recognised the new libraries, and complied without error.

The new B4A library works fine on android 4.0.4 but not on 4.4.2

Looking though the un-filtered logs, i can see where it fails, but not why!
All i can see is

1D Power up Fail.........
open() err:-1​

(see below log snips)

Any help would be appreciated

Have you tried to uninstall the app and then install it again?

Hi Erel,

Found the issue,

i did not update the DeviceApi.jar in C:\Program Files\Anywhere Software\Basic4android\libraries
cw-deviceapi.jar had to be renamed to deviceapi.jar and copied to C:\Program Files\Anywhere Software\Basic4android\libraries

It worked on the 4.0.4 because it found the older version DeviceApi.jar that was already there from my earlier version install.
(the newer version DeviceApi.jar is for 4.0.4 and 4.4.2)

Im am a bit uncertain as to when and why some libs get copied to
C:\Program Files\Anywhere Software\Basic4android\libraries
when its already in the SLC lib folders.


Thank you for your reply Erel.

Lee.
