Question

ERROR MESSAGE:

jarsigner: Certificate chain not found for: project_foo.

project_foo must         


        

Answer 1

i had the same issue my commands were

to generate key

 keytool -genkey -v -keystore testapp-key.keystore -alias testapp-key -keyalg RSA -keysize 2048 -validity 10000

and then i did this to sign the app

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore testapp-key.keystore testapp.apk testapp

i got this error

jarsigner: Certificate chain not found for: testapp.

project_foo must reference a valid KeyStore key entry containing a private key and corresponding public key certificate chain.

then i replaced the alias 'testapp' in the jarsignir command with the key alias that is 'testapp-key' it is in first command i.e. key generation command

the command will look like this

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore testapp-key.keystore testapp.apk testapp

in your case it will be like this

 jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore C:\Path\\.keystore Foo.apk your-key-alias
