Android import apk file problem

I have created a keystore and created a apk file for version 1.0 of the app with the same keystore. But after that du开发者_如何学运维e to some prob, my pc is crashed and no more usable. But I have the keystore file using which I have developed the apk for version 1.0. Now I want to release version 2.0 of the same app. I used the same code-base and build the apk using the same keystore file. I tried to upload it to the Android Market, but it rejected the apk file. What is reason behind it? What is solution for the problem?

Not only the keystore is important, but the same key should be used to sign the apk.

Maybe you have tried to upload the 'debug'-apk instead of the release-apk. The only other explanation is that you have signed it with a different keystore file - or with a different key from the same keystore. Check your file paths.

Make sure that you have used the same password(key) and keystore that was created for the earlier version 1.0.

Check your manifest file too that have you modified the version name and version code.

See this part of your manifest file:

  android:versionCode="2"    // New version code
  android:versionName="1.1"   // New version name

Hope this will solve your issue.
