Slow Android Browser Performance

I am writing a game with javascript. This application works well in my browser (fast), but I have some problems running this with an Android web browser.

• Application startup time takes 5 seconds or more (I think this is a slow process, but maybe this is normal?)

• In the game menu, I have a method like:

  this.showCredits = function() {
  document.getElementById('core-credits-layer').style.display = 'block';
  document.getElementById('core-credits').style.display = 'block';
  var parent = this;
  
  $.ajax({
      url: 'content/credits.html',
      dataType: 'html',
      success: function(data, status, response) {
          var  now = new Date();
          var s = now.getSeconds()-parent.test.getSeconds();
          console.log('success ajax: '+s);
          document.getElementById('core-credits').scrollTop = 0;
          document.getElementById('core-credits').innerHTML = response.responseText;
          console.log('finished');
      },
      error: function() {
          console.error('failed fetch credits');  
      }
  });
  }
  

  So, the console log ("finished", the last line in success ()), immediately after clicking the "loans" menu. But it can take 6 seconds (more or less) until I see the div # core-credits. In my browser, I see # core-credits right after clicking. But the second time, by clicking on this menu point, I get a div after 1-2. I’m not sure what it is now, I don’t think it’s caching because I quickly switch to callback ().

Java:

    public void onCreate(Bundle savedInstanceState)
{
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    Context context = this.getApplicationContext();

    SharedPreferences wmbPreference = PreferenceManager.getDefaultSharedPreferences(this);
    boolean isFirstRun = wmbPreference.getBoolean("FIRSTRUN", true);
    if(isFirstRun) {
        this.copyAudioFiles(context);
    }

    WebView mWebView = (WebView) findViewById(R.id.webview);
    mWebView.getSettings().setJavaScriptEnabled(true);
    mWebView.getSettings().setDomStorageEnabled(true);
    mWebView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);

    String data = context.getFilesDir().getPath();
    mWebView.getSettings().setDatabasePath(data+"data/"+this.getPackageName()+"/databases/");
    mWebView.getSettings().setAllowFileAccess(true);
    mWebView.setWebChromeClient(new WebChromeClient());
    String data_root = Environment.getExternalStorageDirectory()+"/"
        +this.getPackageName();
    mWebView.loadUrl("file:///android_asset/www/index.html?system=android&" +
        "data_root="+data_root);  
}
