Help with setup to monitor USB serial with terminal app on Android 4.3+ device

I'd like to monitor printf() data with an Android Phone or Tablet. I have Nexus 7 1st gen. with Kit Kat and HTC one with 4.3.

Background: I have a KL25Z program using: Serial pc(USBTX, USBRX) outputting text that is successfully read on Win xp PC using Tera Term using Mbed win driver. The PC USB connection is to KL25Z SDA's USB connector.

Using a USB otg conversion cable (micro usb to USB A) connected to my Android device and the other end connected to KL25z SDA's usb, I fail to see anything with various USB terminal apps from play store. e.g., "USB terminal" & "Free USB serial."

I can't tell why. USB OTG problem, power problems, driver problems, etc.

Has anyone done this successfully? Can you please tell me how? Thanks so much! Keith
