i\'m trying to check if my signed release apk is really signed. But following some tutorials, or the single i\'ve found .
$ jarsigner -verify -verbose -certs my_
C:\Program Files\Java\jdk1.8.0_211\bin
*if this not work then
set PATH=C:\Program Files\Java\jdk1.8.0_211\bin
now the path is set now you can use the jarsigner
