Simple class that reads res/raw text file using Scanner.class It has got one static method that require the Context and the resource id of the file to be read. It is a simple demonstration of reusability. The other way is to use a succession of InputStream - InputStreamReader - BufferedReader to read that res/raw text file.

InnerReader.java

import android.content.res.*;
import java.util.*;
import android.content.*;

public class InnerReader 
{
 
 public static String readText(Context context, int resId){
	StringBuilder sb = new StringBuilder();
	Scanner reader = new Scanner(context.getResources().openRawResource(resId));
	try{
	 while(reader.hasNextLine()){
		sb.append(reader.nextLine());
		sb.append(System.lineSeparator());
	 }
	}catch(Exception e){}
	finally{
	 reader.close();
	}
	return sb.toString().trim();
 }
}
