问题
I got this error message when I try to install for testing my app from android market
"Installation error." It's followed by "Unknown reason-102".
Is this my apk or my phone???

I solved this with using a different signing certificate. The Android docs suggest a life of 10,000 days, but that now creates expiry dates after the end of time in *nix timestamps, which is some time in 2038. I generated a new cert that expires in 2037 and resubmitted the apk and it now installs ok. Unfortunately I had to change the identifier of the app and copy all the descriptions/graphics to the "new" app because play won't let you change the cert on an existing app.
I could install my apk directly on my phone but when it came through market/play it would fail, every time. I thought it was getting corrupted during the submission process and google said they could not help me. It looks like a bug the market/play app to me.
