Question

如何在同一应用不同的活动中使用XWalkView和WebView？在Android中，KITKAT webview不支持上传。 Crosswalk修好了它。但现在我在两个不同的活动中使用了两个不同的webview（XWalkView和WebView）。

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);
    }

并收到此错误
