As @mladen-gavrić comment his own question, downgrade to java JDK version 1.6. solves the issue.

SE with $ java -vwith version is currently running which will output something like the following:

java version "1.8.0_65"
Java(TM) SE Runtime Environment (build 1.8.0_65-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.65-b01, mixed mode)

See this excellent answer how to downgrade with the JDK 1.6. already installed previously: https://stackoverflow.com/a/24657630/2797243

Older Android devices are unable to recognize SHA256 hash funcitons. Adding:

-sigalg SHA1withRSA -digestalg SHA1

as parameters to jarsigner should solve the issue even when using JDK 1.8.
