You can create a new keystore  but the Android Market wont allow you to upload the apk as an update - worse still  if you try uploading the apk as a new app it will not allow it either as it knows there is a  different  version of the same apk already in the market even if you delete your previous version from the market  Do your absolute best to find that keystore    When you find it  email it to yourself so you have a copy on your gmail that you can go and get in the case you loose it from your hard drive

As everyone has said  you definitely need the key  There s no workaround for that  However  you might be surprised at how good the data recovery software can be  and how long the key may linger on your systems -- it s a tiny  tiny file  after all  and may not yet be overwritten  I was pleasantly surprised on both counts   I develop on an OSX machine  I unintentionally deleted my app key around 6 weeks ago  When I tried to update  I realized my schoolboy error  I tried all the recovery tools I could find for OSX  but none could find the file -- not because it wasn t there  but because these tools are optimized to find the sorts of files the majority of users want back  photos  Word docs  etc    They re definitely not looking for a 1KB file with an unusual file signature   Now this next part is going to sound like a plug  but it isn t -- I don t have any connection to the developers   The only recover tool I found that worked was one called Data Rescue by Prosoft Engineering  which I believe works for other files systems as well -- not just HFS    It worked because it has a feature which allows you to train it to look for any file type -- even an Android key  You give it several examples   I generated a few keys  filling in the data fields in as like manner as possible to the original   You then tell it to  deep search   If you re lucky  you ll get your key back in the  custom files  section   For me  it was a life saver   It s  100 to purchase  so it s not cheap  but it s worth it if you ve got a mass of users and no further means of feeding them updates    I believe they allow you 1 free file recovery in demo mode  but  unfortunately  in my case  I had several keys and could not tell which one was the one I needed without recovering them all  file names are not preserved on HFS     Try it first in demo mode  you may get lucky and be able to recover the key without paying anything   May this message help someone  It s a sickening feeling  I know  but there may be relief

If you lost a keystore file  don t create update the new one with another set of value  First do the thorough search  Because it will overwrite the old one  so it will not match to your previous apk    If you use eclipse most probably it will store in default path  For MAC  eclipse  it will be in your elispse installation path something like    Applications eclipse Eclipse app Contents MacOS   then your keystore file without any extension  You need root privilege to access this path  file

I want to refine this a little bit because down-votes indicate to me that people don t understand that these suggestions are like  quot last hope quot  approach for someone who got into the state described in the question  Check your console input history and or ant scripts you have been using if you have them  Keep in mind that the console history will not be saved if you were promoted for password but if you entered it within for example signing command you can find it  You mentioned you have a zip with a password in which your certificate file is stored  you could try just brute force opening that with many tools available  People will say  quot Yea but what if you used strong password  you should bla bla bla    quot  Unfortunately in that case tough-luck  But people are people and they sometimes use simple passwords  For you any tool that can provide dictionary attacks in which you can enter your own words and set them to some passwords you suspect might help you  Also if password is short enough with today CPUs even regular brute force guessing might work since your zip file does not have any limitation on number of guesses so you will not get blocked as if you tried to brute force some account on a website
