It crashes on both my ARM and x86 tablets. ( both on Android 4.4, one has ARM RK3188 SOC, the other has Intel Atom Z3735 SOC. )

Please at least tell me if the error comes from my part or if it is a bug in Crosswalk.
I reinstalled Android Studio and Java, redownloaded your project, even reseted my tablet, but I still get this error.

I myself using older crosswalk for api =<21 due to crashes. Use crosswalk 54 for new api only.

Thanks for your reply.
What a shame, I stopped using the old Crosswalk because it had too serious bugs in both webaudio and html5audio, and my two testing devices have Android 4.4.
I see some people are setting up a funding and you will work on it. Is there any chance a future version will be compatible again with Android older than 5 ? I think Crosswalk is especially useful for supporting older Android versions because their webview can't be used for it is obsolete and can't be updated.

Are you still working on it ? Anything new ?

by next month I will start on chrome 64. Pakistan Data Management Services p: +92 21 3455 9003 w: www.pakdata.com <https://facebook.com/pakdata> <https://twitter.com/hashtag/Pakdata> <https://www.instagram.com/pakdataapps/>
