how to get value from a text file and link with firebase
0
I have a text file containing userPhone and the relevant foodId for recommendation purposes in a menu app.
I have successfully read the relevant foodId based on each userPhone login. How am I able to get the foodId from the text file and retrieve from firebase to display in recycler view? foodId are stored in firebase.
(different user login will display the relevant foodId based on each phone number). I am just a beginner. Thanks in advance

String userPhone = Common.currentUser.getPhone();
String recommend = findRecommendation(userPhone);
if (recommend != null) {
recList.setText(recommend);
} else {
recList.setText("Not enough transaction");
}
}
private String findRecommendation(String userPhone) {
//open raw resource and connect to input stream variable

//scanner

String line = scan.nextLine(); //phoneNo + foodId
String pieces = line.split("=");
if (pieces[0].equalsIgnoreCase(userPhone.trim())) {
return pieces[1];
}
}
return null;

Please be more precise to what you're saying, it's a bit unclear, If you could take an example to tell, it would be better for people to understand.

why are you keeping phone numbers in a file like that it will unnecessary increase the app size. better you keep eveything in firevase database and get the recommended data for the user

@PradyumanDixit im storing relevant foodId based on each userPhone which is for recommendation purposes. When the user login based on their phoneNumbers, the app will only recommend the food found in the textfile based on the userPhone. All foodId are stored in firebase. However, i do not know how to display the only foodId in the text file where can be retrieved from firebase.

@HarKal i do not know how to store only specific foodId based on each userPhone. Because i already have all foodId in my firebase. So i save in a textfile and read each foodId based on each user login for recommendation purposes in a restaurant menu.
