I have uploaded a new preview to
http://code.google.com/p/bitcoin-wallet/downloads/listIt has new, more efficient networking code and uses memory more efficiently. This saves battery power and allows for larger (in bytes) wallets.
It allows sending coins to P2SH addresses. Also, if sending it now has more specific error messages, e.g. when running out of funds.
Any testing done on the bitcoinj 0.11-based previews is appreciated. Bitcoinj 0.11 is due out the next weeks, and an app release will follow.
