Video [Q] Editting Needed in APP | NO ROOT

Hi Guys Out there.
i need help from you if you can modify [NExtRadio APP] LINK& edit this app so that apart from searching ODD Frequencies it also start searching EVEN Frequencies.

If anyone can make this modification then by the help of "HeadsetButton Controller App" we would be able to Switch Tracks Via Default Headset even in Radio App.

Curretly in india it searches following Stations:

91.10
93.50
98.30

But it want it should also search Even Frequency Stations Like:

95
104
104.80
102.60
106.40


Thanks in advance.
