It is possible to change the font of the elements in the conversation view. In order to do this, there are two separate settings:
custom_font_name_conversation_feed for the font of the elements in the conversation feed itself and
custom_font_name_non_conversation_feed for the elements that are not in the conversation feed (e.g., font on the Enter Message EditText control, toolbar text etc.). Refer to the Custom Fonts section for the parameters description.
The above font parameters accept either a standard Android font name (e.g., sans-serif-thin) or a custom installed TTF font. The custom font file should resides on the assets folder in the host app, located as a sibling of the res folder. If a custom font is used, the above font parameters should be the custom font file name including the TTF extension (e.g., customFont.ttf)
