"The certificate that signed this apk is not valid until the future. Create a new certificate."
And Apk dnt be uploaded please any one help me or tell me where will be the issue i have exported it as apk file its certificate information as required in eclips
There is probably some issue with the certificate. The certificate guide lets you create a certificate valid for many years, which it suggests to make at leat 25. Double check if you made sure that is correct.
OR
Try moving your system time back one day and sign your app, should be a fair workaround :)
