Admob banner size for different devices

Question

Just two days back, I came to know that SMART_BANNER is not the best for good CTR and we should dynamically switch between ad sizes for admob. Here is the Java code, I have written. When I ran the code on a 4inch emulator, I see that 728x90 ad is requested and the response is invalid ad size. (description of error is that ad won't fit the current screen) pls. help: ``` AdSize adsize = AdSize.SMART_BANNER; Display display = getWindowManager().getDefaultDisplay(); int width = display.getWidth(); int height = display.getHeight(); int orientation = display.getOrientation(); if(width >= 728 && height >= 90 ) { adsize = AdSize.IAB_LEADERBOARD; System.out.println("728 x 90"); } else if (width >= 468 && height >= 60 ) { adsize = AdSize.IAB_BANNER; System.out.println("468 x 60"); } else if (width >= 320 && height >= 50 ) { adsize = AdSize.BANNER; System.out.println("320 x 50"); } LinearLayout adContainer = (LinearLayout) findViewById(R.id.cakes); adView = new AdView(this, adsize, "xxxxxxxxxx")…

Accepted Answer

`getWindowManager().getDefaultDisplay().getWidth()` returns the width in pixels. You need to be making a decision on which banner to show based upon the width in density independent pixels.

I decided a long time ago that the best solution was to use Android resource config to specify the adBannerSize. Eg

```
final AdSize adSize;
final int adBannerSize = getResources().getInteger(R.integer.adBannerSize);
switch (adBannerSize) {
    case 1 :
        adSize = AdSize.BANNER;
        break;
    case 2 :
        adSize = AdSize.IAB_BANNER;
        break;
    case 3 :
        adSize = AdSize.IAB_LEADERBOARD;
        break;
    default:
        Log.w(TAG, "No AdSize specified");
        adSize = AdSize.BANNER;
        break;
}
```

Then you can easily configure the ad banner size to match whatever device configuration you intend to support.
