How to use XWalkView and WebView in same app?

Question

How Can I use XWalkView and WebView in same app different activity? In Android KITKAT webview doesn't support upload. Crosswalk fixed it. But now I use two different webview (XWalkView and WebView) in two different activity.

if(sdkVersion == Build.VERSION_CODES.KITKAT){
        Intent myIntent = new Intent(StartActivity.this, MainActivity.class); // this use XWalkView
        StartActivity.this.startActivity(myIntent);
    } else {
        Intent myIntent = new Intent(StartActivity.this, Main2Activity.class); // this use Webview
        StartActivity.this.startActivity(myIntent);
    }

And get this error

    java.lang.RuntimeException: Unable to start activity
    ComponentInfo{com.example.foo/com.example.foo.Main2Activity}:

You wouldn't use Webview anymore and why would you mix the two? Pick one and stick with it. Crosswalk in your case . — basic, Jul 14 '16 at 17:15
Because Crosswalk performance less than Webview in middle and low level power device. — Farid Valiyev, Jul 14 '16 at 17:20
the logcat says the error occurs during Main2Activity's onCreate, can you post Main2Activity.java? — Bill, Jul 14 '16 at 17:35
