Error while signing an kivy app for the android store

Question

I tried to sign my application, which is called LieDedector-1.2.0-release-unsigned.apk and programmed in kivy, for the android store with jarsigner . Both the apk and my keystore, called My1Key.keystore , are in the keystores directory. So I tried to sign my app with to following command:

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore ./keystores/My1Key.keystore ./keystores/LieDedector-1.2.0-release-unsigned.apk cb-play

And I got the error message:

jarsigner: Certificate chain not found for: cb-play. cb-play must reference a valid KeyStore key entry containing a private key and corresponding public key certificate chain.

Why can't I sign my app?

Answer 1

It seems like that would be is related to the naming of your keystore. Our command is almost identical and works. It's the last item, cb-play, where (I think) it goes wrong....

Certificate chain not found, how to fix and publish to Google Play Store?

Answer 2

Thank you very much, I did it! I did it like this:

1. I generated an release apk with

   buildozer android release

2.Than I created a keystore

3. Than I found out my alias name with: keytool -keystore My1Key.keystore -list -v

The output should look like this:

Keystore-Typ: JKS
Keystore-Provider: SUN

Keystore enthält 1 Eintrag

Aliasname: m1k
Erstellungsdatum: 31.07.2015
Eintragstyp: PrivateKeyEntry
Zertifikatskettenlänge: 1
Zertifikat[1]:

In my case, the aliasname was m1k

4. Than I generated signt my apk file with:

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore ./keystores/My1Key.keystore ./keystores/LieDedector-1.2.0-release-unsigned.apk m1k

(I had both my apk and my keystore in the keystores direktory, my apk was called LieDedector-1.2.0-release-unsigned.apk my keystore My1Key.keystore and the aliasname was m1k )

I hope this helps someone :)
