Hi,
I have publish app to googleplay success.
Now how i can upload new version? I don’t know re-signing app 
or new signing
Do exactly what you did before (use the same keystore file), but just bump the version number up in config.xml, i.e if it was 1.0.0 you should make it 1.0.1 or 1.1.0 or 2.0 etc. It just needs to be higher than the previous version.
Rebuild the app, upload the APK to Google Play and you should be all good.
Thank for reply
I build using: sudo ionic build android.
GooglePlay error app not signing
Maybe you should do some reading in the docs overe here: http://ionicframework.com/docs/guide/publishing.html
"Updating your App
As you develop your app, you’ll want to update it periodically.
In order for the Google Play Store to accept updated APKs, you’ll need to edit the config.xml file to increment the version value, then rebuild the app for release."
==> hmm
jarsigner error: java.lang.RuntimeException: keystore load: Keystore was tampered with, or password was incorrect
this means you used a wrong password for the keystore or you aren’t pointing to the right keystore file. That’s what is causing this error message. Yes, you should always increment the version number in your config file before submitting to play/itunes stores, but it doesn’t break your build…
