android - 嵌入式 Crosswalk 增加了 Android 上分配的内存

Question

我有几个 web 应用程序，我希望能够通过 native android 应用程序中的 webview 运行。我目前正在嵌入人行横道浏览器并在其中加载应用程序。它适用于某些 Web 应用程序，但随着 Web 应用程序大小的增加，我收到导致我的 Android 应用程序崩溃的错误。

我尝试过的事情:

• android:largeHeap="true"- 帮助我能够运行更大的网络应用程序。
• android:hardwareAccelerated="true"- 帮助我获得更好的性能。
• assets/xwalk-commandline 中的 xwalk-command-line='--ignore-gpu-blacklist' - 也有帮助

仍然有一些 Web 应用程序(通过 unity 创建)在我创建它们用于桌面测试时需要分配大约 1Gb。我将在最新的手机上使用这个 android 应用程序，并且可以接受如此高的内存使用率。

如果我尝试在桌面浏览器上打开此应用程序，它会起作用，这让我相信这是一个内存分配问题。我正在使用启用了 webGL 的人行横道 17，较小的应用程序运行 webgl 也很好。

我有几个问题:

1. 有没有办法强制 crosswalk 嵌入式浏览器为自己分配 1GB 内存。 (我知道这会压坏我的设备，可能不是很好，但请原谅我)
2. 我能否将我的应用程序的内存使用量扩展到 largeHeap 之外。如果是这样怎么办？我是否需要这样做才能启用如此大型的 Web 应用程序？
3. 是否有任何我遗漏的问题可能掩盖了这里的真正问题。
4. 我知道这种类型的应用程序只能在最新型的手机上运行。具有如此高内存使用率的应用程序会产生什么影响？
5. 我是否应该探索任何其他途径来使我能够在 Android 应用程序中运行大型 Web 应用程序？

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>

创建时的 Activity :

@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);

权限

*Crosswalk 需要很多这些，我正在使用其余部分。但也许那里有冲突。

我遇到过这样的问题。我认为这个问题来自于 adsense 之类的广告，或者一些 JavaScript 出了问题

尝试

 xwalk Release 'org.xwalk:xwalk_core_library:21.51.546.7'

希望对你有帮助
