Android 2.3 Has Lower Vm Budget Than 2.1 And 2.2?

It seems like Android 2.3 has much smaller VM budget than 2.1 amd 2.2. I am suprised that the newer OS is more restrictive, I would expect that due to the development of technology

Solution 1:

Android 2.3's VM budget is actually higher (32 MB.) The difference is that Android 2.3 now loads all bitmaps in 32 bits (ARGB8888) by default instead of 16 bits.
