android – 使用一段时间后,我的应用程序在滚动WebView期间冻结,说“无法锁定表面”

我的 Android应用程序包含几个活动,每个活动负责单个片段(现在).我的碎片通常@L_801_1@/附加有点像这样： @H_992_2@mTopicFragment = (TopicFragment)getSupportFragmentManager().findFragmentByTag("topic"); if(mTopicFragment == null) mTopicFragment = TopicFragment.newInstance(bid,page,pid); if (savedInstanceState == null) { getSupportFragmentManager().begintransaction() .add(R.id.content,mTopicFragment,"topic") .commit(); }

TopicFragment包含@L_197_2@@L_801_1@一些HTML和CSS / JS东西的WebView.经过一段时间浏览应用程序,其中@L_197_2@TopicFragment WebView中的滚动变得缓慢,最终,应用程序完全冻结. ADB日志@L_801_1@以下异常：

在互联网上,我只能找到有关这个例外的信息,人们有自己的视图.这里发生了什么？它可以与我的应用程序的内存消耗有关吗？看起来好像我每次调用上面的代码一样,新的TopicFragment被实例化,@L_801_1@并推送到后面的堆栈.我该如何进一步调试这个行为？

还有@L_197_2@信息：当我在开发者设置中启用重叠时,应用程序似乎使用了大量的cpu.可能是,当我离开他们的时候,我的碎片没有正确分离,并且由于某种原因在后台运行？

这是我如何使用WebView：

@H_992_2@mWebView = (WebView)getView().findViewById(R.id.topic_webview); mWebView.getSetTings().setJavaScriptEnabled(true); mWebView.getSetTings().setDomStorageEnabled(true); mWebView.getSetTings().setCacheMode(WebSetTings.LOAD_NO_CACHE); mWebView.getSetTings().setAllowFileAccess(true); mWebView.addJavascripTinterface(mJsInterface,"api"); mWebView.setWebChromeClient(new WebChromeClient()); mWebView.loadData("","text/html","utf-8"); mWebView.setBACkgroundColor(0x00000000);

这不是内存泄漏提到here.

@Override
public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle saved) {
    View v = super.onCreateView(inflater,container,saved);

    mActivity = (BaseActivity) getSupportActivity();

    // this is the framelayout which will contain our WebView
    mWebContainer = (FrameLayout) v.findViewById(R.id.web_container);

    return v;
}

public void onResume() {
    super.onResume();

    // create new WebView and set all its options.
    mWebView = new WebView(mActivity);
    mWebView....

    // add it to the container
    mWebContainer.addView(mWebView);

    // if Data is available,display it immediately
    if(mTopic != null) {
        mWebView.loadDataWithBaseURL("file:///android_asset/",mTopic.getHtmlCache(),"UTF-8",null);
    }
}

@Override
public void onPause() {
    super.onPause();

    // destroy the webview
    mWebView.destroy();
    mWebView = null;

    // remove the view from the container.
    mWebContainer.removeAllViews();
}
