OutOfMemory error in Android with the latest AdMobSDK

I have implemented the newest version of the AdMobSDK in one of my aps and I get the following error every time the application requests a new ad:

I am using AdMob version 4.1.0. With the old version of AdMob (version 20101109) the application works fine. Can someone suggest a solution? I am testing the application on a Samsung Galaxy S phone. The strange thing is that it used to work before, and I sometimes view ads in the 开发者_开发知识库application.

I am not using any large bitmaps in the application, only a few 15 tp 35 K png files - I am also using recycle for some Bitmap decode operations.

Can someone suggest a solution?

Thanks
