[Android Trouble with using Crosswalk for webview on android

cocos2d-x C++
1

Hi.

I’m developing game by cocos2d-x (c++).
I used webview for my app to show contents.
Because its contain some heavy process (javascript), I need more performance.

So, I decided to use alternative webview, crosswalk. https://crosswalk-project.org/
Using crosswalk for simple test project is ok.
But, use with cocos2d-x, some device raise error.
My android device F-02E works good.
But, Nexus7 is not.
Nexus7 raise an error soon, when app become running:
java.lang.UnsatisfiedLinkError: Couldn’t load cocos2dcpp from loader
(from logcat)

Another way, I tested adding cpu by editing ./cocos2d/plugin/protocols/proj.android/jni/Application.mk and ./proj.android/jni/Application.mk like that:
APP_ABI :=armeabi armeabi-v7a x86
Then, Nexus7 raise a different error:
java.lang.UnsatisfiedLinkError: dlopen failed: cannot locate symbol “srand” referenced by “libcocos2dcpp.so”
(from logcat)

I have no idea anymore…
Does anyone succeed to work crosswalk? or, have any Ideas?

I solved the error about “srand” by down version NDK (r10d => r9d).
cf. https://anhdodeveloper.wordpress.com/2015/04/06/cannot-locate-symbol-srand/
So, I can use crosswalk with both F-02E and Nexus7.

But, because I use cocos2d-x v3.5, NDK r9d is not good.
A warning “Your application may crash or freeze on Android L(5.0) when using BMFont and HttpClient.” is raised when build.

So, I want to use NDK r10d and avoid the error.
Does anyone have any ideas…?
