changing admob banner size dynamically

Question

Here is the thing, as you might know Admob has a AdSize.* function, where u put Banner to show banner ads, and AD_banner` for tablet banners, what i want to do is take a screen size of a device so that i could throw it in my if statement and then put the right banner for right device, i hope i was clear enough.So anyone can tell me how can i get the screen size of device? Thank u ////////// Here's what i have done so far

     DisplayMetrics dm = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(dm);

       if (dm.density==DisplayMetrics.DENSITY_HIGH) {
        AdView adView = new AdView(this, AdSize.BANNER,s);
        LinearLayout layout = (LinearLayout)findViewById(R.id.admob);
        layout.addView(adView);
        adView.loadAd(new AdRequest());
       }
       if (dm.density==DisplayMetrics.DENSITY_DEFAULT || dm.density==DisplayMetrics.DENSITY_LOW ) {
             AdView adView = new AdView(this, AdSize.BANNER,s);
             LinearLayout layout = (LinearLayout)findViewById(R.id.admob);
             layout.addView(adView);
            adView.loadAd(new AdRequest());

        }
        if(dm.density==DisplayMetrics.DENSITY_MEDIUM)
        {
            AdView adView = new AdView(this, AdSize.IAB_BANNER,s);
            LinearLayout layout = (LinearLayout)findViewById(R.id.admob);
            layout.addView(adView);
            adView.loadAd(new AdRequest());

        }

Answer 1

The most recent AdMob SDK includes AdSize.SMART_BANNER which enables the best size matched ad for the device.

I was using an older version myself and didn't knew about this feature :D

If your layout is define in a xml, you can create one layout per screen size (layout-xlarge/mylayout.xml, layout-large/mylayout.xml, layout-normal/mylayout.xml, etc...)

More info here : http://developer.android.com/guide/practices/screens_support.html

Don't look at density, because, a 10.1" tablet has a medium density, but a 4.3" phone with a 480x850 resolution will have a high density. Use screen size instead (xlarge large normal small).

If you need to do it programatically, you can get the screen size with this :

Configuration config = activity.getResources().getConfiguration();
int screenlayout = config.screenLayout;

and to compare, use Configuration.SCREENLAYOUT_xxx .
