How to read a text file in Android studio when I have the path of that file

This Below one works for me… :)

1. //Read File 
2. readButton.setOnClickListener(new View.OnClickListener(){ 
3.  
4. @Override public void onClick(View arg0) { 
5. String filename=editTextFileName.getText().toString(); 
6.  
7. StringBuffer stringBuffer = new StringBuffer(); 
8. try { 
9. //Attaching BufferedReader to the FileInputStream by the help of  
10. InputStreamReader BufferedReader inputReader = new BufferedReader(new  
11. InputStreamReader(getContext().openFileInput(filename))); 
12. String inputString; 
13.  
14. //Reading data line by line and storing it into the stringbuffer  
15.  
16. while ((inputString = inputReader.readLine()) != null) { 
17. stringBuffer.append(inputString + "\n"); 
18. } 
19.  
20. } catch (IOException e) { 
21. e.printStackTrace(); 
22. } 
23. if(stringBuffer.toString().length() == 0){ 
24. Toast.makeText(getContext(),"File not Available...!", 
25. Toast.LENGTH_LONG).show(); 
26. return; 
27. } 
28.  
29. else { 
30. //Displaying data on the toast Toast.makeText(getContext(), stringBuffer.toString(), 
31. Toast.LENGTH_LONG).show(); 
32. return; 
33. } 
34. } 
35. });
