Hi, Andrew
Both LG G4 (LG-H815) and Samsung Galaxy S6 (SM-G920F) are 64bit devices, but
the 64bit lib so has not been released.
There are two workarounds for 64bit devices:
1. adb install –abi=armeabi test.apk // it only works on rooted devices.
2. Assume that you are using cordova, please create a folder named
armeabi-v7a under “platforms/android/libs”,
then create an empty lib so, the name format like as ”lib*.so”, e.g.
libxwalktest.so, put it under armeabi-v7a
then build your project.
Please look at https://crosswalk-project.org/jira/browse/XWALK-4978 for the
reference.
Thanks.
BRs,
Hengzhi Wu

Any suggestions?
I'm guessing this is caused by ProGuard (which unfortunately I can't disable as
otherwise our app is over the 65k function limit.
Thanks,

Hi Andrew,
Before the log “Please extend XWalkActivity for shared mode”, you can see
“Failed to load native library”. In most cases, it means the native library
embedded in your app doesn’t match the CPU architecture of the device. After
this, the app will try to initialize shared mode instead, but you didn’t use
XWalkActivity, then the crash happened.
Could you tell me which Crosswalk AAR are you using and the specific devices
where the crash occurred?
Thanks,
Lin

Subject: [Crosswalk-help] Please help with XWalkView native crash on some
devices
Hi all,
I've recently updated our application to use Realm (realm.io<http://realm.io/>)
instead of SQLite for our data storage needs, along with a variety of other bug
fixes.
However, while the new version of the app works fine on 6+ devices I've tested
on (spanning android versions such as 4.1.2, 4.3, 4.4.4, 5.1.1), it crashes on
startup on one or two specific devices.
These devices have no problem with the previous version of our application, but
I'm having trouble figuring out what of my changes is causing the new version
to crash.
The Crosswalk AAR bundle I'm using hasn't changed from the old app to the new
one, and while trying to narrow down the problem I've found that I can cause
the old version to break if I simply include the Realm library as a Gradle
dependency!
This makes me suspect it's something proguard-related, but it doesn't really
explain why it's only happening on one specific device.
Anyway, here's the crash log from my LG G4 (one of 2 devices I've found it's
broken on so far):

Obviously that error ("Please extend XWalkActivity for shared mode") isn't
particularly informative, as it's totally irrelevant to how crosswalk is being
used in our app (embedded mode).
I'm struggling to figure out what the next step is to debug this - because it's
a crash in the native crosswalk build, I can't debug it using any of my usual
Android debugging techniques.
Any help would be greatly appreciated.
Kind regards,
Andrew
