Same here but in my case it's a live application.
If I rotate the device (Nexus One 2.34 or Atrix 2.22) the allocated
memory goes up from less than 4 MB to more than 6 MB with every
rotation till it crashes.
If I remove the following line: adView.loadAd(adRequest); from my
code, the memory allocation always stays below 4 MB.
