1) Read .csv file from phone, 2) Seach for a keyword 'Apple4321' 3) If keyword found, then look for the nearest word if it is 'send' 4) If the word 'send' is found do some action like 'play music'

I prefer to use .csv file. I think that the automation app 'Tasker' can save the file frequently whenever there is any update in it.

Remember, you have to use SAF to read/write non media files your app does not own, see also Some basics on Android storage system

Also you might want to think about how you plan to solve the problem of 2 processes (Tasker and your app) writing at the same time
