The Android system requires that all installed applications be digitally signed with a
certificate whose private key is held by the application's developer.
before submit release on google play your application must be build in release mode.
Signing in Release Mode:
When your application is ready for release to other users, you must:
1-Obtain a suitable private key
2-Compile the application in release mode
3-Sign your application with your private key
Generating private Key:
To generate a self-signed key with Keytool.Keytool is java tool for generating private key. use following command to generate private key for signing your android application:
keytool -genkey -v -keystore app_signing.keystore -alias <alias_name> -keyalg <alg> -keysize <size> -validity 10000
where:
-genkey : Generate a key pair (public and private keys).
-v : Enable verbose output.
app_signing: name of your key_file.
-alias : An alias for the key. Only the first 8 characters of the alias are used.
-keyalg <alg>: The encryption algorithm to use when generating the key. Both DSA and RSA are supported.
-keysize <size>: The size of each generated key (bits). If not supplied, Keytool uses a default key size of 1024 bits. In general, we recommend using a key size of 2048 bits or higher.
-validity <valdays> : The validity period for the key, in days.A value of 10000 or greater is recommended.
==================================================
Note: during creation of private key system ask for storeKey password,give any password and remember that password.it will required when you build the application in release mode.

2- upload application.zip folder(compressed file of your application's www folder).
3- unlock your private key by your storekey password.
4- build your application.
--------------------------------------------------------------------------------------------------------------------------------
if you download your build app.apk from https://build.phonegap.com/
you can see that it is a app-release.apk.this build is signed build and you can just upload it on google play.
