How can I read a text file in Android?

I want to read the text from a text file. In the code below, an exception occurs (that means it goes to the catch block). I put the text file in the application folder. Where should I put this text file (mani.txt) in order to read it correctly?

    try
    {
        InputStream instream = openFileInput("E:\\test\\src\\com\\test\\mani.txt"); 
        if (instream != null)
        {
            InputStreamReader inputreader = new InputStreamReader(instream); 
            BufferedReader buffreader = new BufferedReader(inputreader); 
            String line,line1 = "";
            try
            {
                while ((line = buffreader.readLine()) != null)
                    line1+=line;
            }catch (Exception e) 
            {
                e.printStackTrace();
            }
         }
    }
    catch (Exception e) 
    {
        String error="";
        error=e.getMessage();
    }

Solution 1:

Try this :

I assume your text file is on sd card

    //Find the directory for the SD Card using the API
//*Don't* hardcode "/sdcard"
File sdcard = Environment.getExternalStorageDirectory();

//Get the text file
File file = new File(sdcard,"file.txt");

//Read text from file
StringBuilder text = new StringBuilder();

try {
    BufferedReader br = new BufferedReader(new FileReader(file));
    String line;

    while ((line = br.readLine()) != null) {
        text.append(line);
        text.append('\n');
    }
    br.close();
}
catch (IOException e) {
    //You'll need to add proper error handling here
}

//Find the view by its id
TextView tv = (TextView)findViewById(R.id.text_view);

//Set the text
tv.setText(text.toString());

Solution 2:

If you want to read file from sd card. Then following code might be helpful for you.

 StringBuilder text = new StringBuilder();
    try {
    File sdcard = Environment.getExternalStorageDirectory();
    File file = new File(sdcard,"testFile.txt");

        BufferedReader br = new BufferedReader(new FileReader(file));  
        String line;   
        while ((line = br.readLine()) != null) {
                    text.append(line);
                    Log.i("Test", "text : "+text+" : end");
                    text.append('\n');
                    } }
    catch (IOException e) {
        e.printStackTrace();                    

    }
    finally{
            br.close();
    }       
    TextView tv = (TextView)findViewById(R.id.amount);  

    tv.setText(text.toString()); ////Set the text to text view.
  }

    }

If you wan to read file from asset folder then

AssetManager am = context.getAssets();
InputStream is = am.open("test.txt");

Or If you wan to read this file from res/raw foldery, where the file will be indexed and is accessible by an id in the R file:

InputStream is = getResources().openRawResource(R.raw.test);     

Good example of reading text file from res/raw folder

Solution 3:
