Question

I am developing custom browser for android. When browser supports javascript, when you surf the site application gets much more Ram than I use browser without javascript support. Please give an advise how to resolve this problem

public void onCreate(Bundle savedInstanceState) {

 mWebView=new WebView(getApplicationContext());
            mWebContainer=(FrameLayout)findViewById(R.id.web_container);
            mWebContainer.addView(mWebView);
            mWebView.getSettings().setUserAgentString("");
            mWebView.getSettings().setJavaScriptEnabled(true);
        mWebView.getSettings().setPluginsEnabled(true);
        mWebView.getSettings().setPluginState(PluginState.ON);
        mWebView.getSettings().setDatabaseEnabled(true);
        mWebView.getSettings().setGeolocationEnabled(true);
        mWebView.getSettings().setSupportZoom(true);
        mWebView.getSettings().setSavePassword(true);
        mWebView.getSettings().setSaveFormData(true);
        }
        ........................................

     private static class HelloWebViewClient extends WebViewClient 
        {

            @Override

            public boolean shouldOverrideUrlLoading(WebView view, String url) 
            {

                 view.loadUrl(url);

                 return true;
            }
        ........................

      protected void onDestroy()
        {

            super.onDestroy();
            mWebContainer.removeAllViews();
            mWebView.destroy();
            mWebView=null;
            System.gc();
        }

created a simple WebView, such as a memory leak.

Answer 1

I’m not sure you have any choice. Memory usage is managed by the webview widget, and so by the system.

So your app will use a lot of memory.
