We just received the dev kit and trying to add a custom payment option for our giftcard\loyalty app. We tried the folowing:
1- Implementing IPoyntTransactionService and following the sample app example.
2- Implementing IPoyntCustomTransactionService and following instructions on the javadoc page (https://poynt.github.io/developer/javadoc/co/poynt/os/services/v1/IPoyntCustomTransactionService.html).
We installed the app using adb but Nnothing of the above seem to work and our custom payment option never shows up. We used every possible value for and <entry_method> in capability file, set the right permissions, target version is 19.
P.S. this same code used to work with the emulator!
