Embedded Crosswalk increase allocated memory on Android

Question

I have a several web application that I want to be able to run through a webview in a native android application. I am currently embedding a crosswalk browser and loading the applications in that. It works great for some of the web applications but as the size of the web application increases I get errors that crash my android application.

Things I have tried:

• android:largeHeap="true" - helped I was able to run larger web applications.
• android:hardwareAccelerated="true" - helped I got better performance.
• xwalk-command-line='--ignore-gpu-blacklist' in assets/xwalk-commandline - also helps

There are still some web applications (created through unity) that required me to allocate about 1Gb when I was creating them for desktop testing. I am will be using this android app on the newest phones and would be ok with such a high memory usage.

It works if I try to open this application on a desktop browser so that is what leads me to believe that it is a memory allocation issue. I am using crosswalk 17 which has webGL enabled and the smaller applications run webgl just fine.

I have a few questions:

1. Is there a way to force the crosswalk embedded browser to allocate 1GB of memory for itself. (I know this is going to crush my device and is probably not great but please indulge me)
2. Can I expand my application's memory usage beyond largeHeap. If so how? And do I need to do so to enable such large web applications?
3. Are there any issues that I am missing that are possibly masking the real issues here.
4. I know this type of application would only ever run on the newest kinds of phones. what are the repercussions for an application that has such a high memory usage?
5. Are there any other avenues I should explore to enable me to run large web applications within an android app?

Here are the answers to the FAQs of stack overflow users :)

Xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.mycompany.myproject.webapplicationActivity">


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

Activity onCreate:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.webapplicationActivity);

    xWalkWebView=(XWalkView)findViewById(R.id.xwalkWebView);

    // turn on debugging
    XWalkPreferences.setValue(XWalkPreferences.REMOTE_DEBUGGING, true);
    xWalkWebView.setKeepScreenOn(true);
    xWalkWebView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN);
    String urlToBeLoaded = "http://www.google.com";

    Bundle bundle = getIntent().getExtras();
    if (savedInstanceState == null) {
        Bundle extras = getIntent().getExtras();
        if(extras == null) {
            Log.i(TAG,"error in reading extras");
        } else {
            urlToBeLoaded = extras.getString("url");
        }
    }
    xWalkWebView.load(urlToBeLoaded, null);

Permissions

*Crosswalk requires a lot of these and I am using the remainder. But maybe there is a conflict there.

Answer 1

I had a problem like that. I thought this problem came with ads like adsense or some went wrong with JavaScript

Try

 xwalk Release 'org.xwalk:xwalk_core_library:21.51.546.7'

I hope that helps you
