I updated yesterday to v3.52, did all that I mentioned above, and today updated to v3.55. The "This Is Your Bitcoin Address" on my wallet with v3.55 has changed and it appears that my old "This Is Your Bitcoin Address" is gone, or swept, or both. idk. I hope the code automatically will monitor those old addresses to make sure any funds are swept to the new addresses. Is this what you want me to test?
The old bitcoin address has been moved into Archived addresses so you will be able to receive funds to it, it is just hidden from the main view. If you could unarchive that address temporally and test sending from that address using the android app that would be great.
It worked. I sent 0.001 to my old "This is Your Bitcoin Address", then spent it using the phone.
Also, @piuk, if you are updating the app:
Do not blank the "Enter PIN" form after the pin is entered: it looks odd. I like the "Validating PIN" notice and the "PIN verified" notice; blank the "Enter PIN" form after the form is down and out of sight, if you know what I mean.
