Crosswalk - Inflating class & Cie

问题

I'm currently working with Crosswalk ( previously on Cordova ). But I encounter a problem : when i'm creating just a simple XWalkView, nothing works..

I mean, I followed all guides, try multiples ways and nothing . I'm working with CrossWalk 12.41.296.9 ARM.

That way:

public class MainActivity extends Activity {
    private static final String url = "file:///android_asset/www/index.html";

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.cordova_layout);
        XWalkView webView = (XWalkView) findViewById(R.id.cordova_webview);
        webView.load(url,null);

    }
}

With this "cordova_layout" :

<org.xwalk.core.XWalkView
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/cordova_webview"
        android:layout_width="match_parent"
        android:layout_height="match_parent">    
</org.xwalk.core.XWalkView>

Or even that way

public class MainActivity extends Activity {
    private static final String url = "file:///android_asset/www/index.html";

    @Override
    public void onCreate(Bundle savedInstanceState)   {
        super.onCreate(savedInstanceState);
        XWalkView cordovaWebView = new XWalkView(this.getApplicationContext(),this);
        cordovaWebView.load(url,null);
        setContentView(cordovaWebView);
    }
}

is giving my that inflating error

Replace this

    XWalkView cordovaWebView = new XWalkView(this.getApplicationContext(),this);
    cordovaWebView.load(url,null);
    setContentView(cordovaWebView);

with

    setContentView(R.layout.cordova_layout);
    XWalkView cordovaWebView = (XWalkView)findViewById(R.id.cordova_webview);
    cordovaWebView.load(url,null);

EDIT: Here is an example that worked for me:

public class MainActivity extends AppCompatActivity {
    private XWalkView xWalkWebView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        getWindow().requestFeature(Window.FEATURE_PROGRESS);
        getWindow().requestFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN
        );
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        xWalkWebView = (XWalkView) findViewById(R.id.xwalkWebView);           
        xWalkWebView.load(url, null);

        // turn on debugging
        // XWalkPreferences.setValue(XWalkPreferences.REMOTE_DEBUGGING, true);
    }

    @Override
    protected void onPause() {
        super.onPause();
        if(xWalkWebView != null) {
            xWalkWebView.pauseTimers();
            xWalkWebView.onHide();
        }
    }

    @Override
    protected void onResume() {
        super.onResume();
        if(xWalkWebView != null) {
            xWalkWebView.resumeTimers();
            xWalkWebView.onShow();
        }
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        if(xWalkWebView != null) {
            xWalkWebView.onDestroy();
        }
    }
}

Layout:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent"
              android:background="#000000">

    <org.xwalk.core.XWalkView
        android:id="@+id/xwalkWebView"
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:background="#000000"
        />

</LinearLayout>

Manifest:

Module-level gradle:

android {

        minSdkVersion 14

    compile 'com.android.support:appcompat-v7:21.0.3'
    compile 'org.xwalk:xwalk_core_library_beta:11.40.277.6'
}

and project level gradle:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
        maven {
            url 'https://download.01.org/crosswalk/releases/crosswalk/android/maven2'
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.1'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        maven {
            url 'https://download.01.org/crosswalk/releases/crosswalk/android/maven2'
        }
    }
}

Please update the outdated Android Gradle plugin, Support library, the Crosswalk version and the compile/buildtool/targetSDK.
