Error with signature on the app Android

If you got some of these errors when try create the signature of your app (or try run calabash-android run) on Android:


> fingerprint_from_apk': No RSA file found in META-INF. Cannot proceed. 




> jarsigner: unable to open jar file (When try re-signed)


Try these steps:


– Verify if the file zipalign is inside of the folder sdk/tools.


– If the zipalign don’t exist inside the tools folder, download on this link :


– Give the execute permissions:

chmod 777 zipalign


– Open the Eclipse, Click in Preferences:
