Access resource files in Android

I have a resource file in my /res/raw/ folder (/res/raw/textfile.txt) which I am trying to read from my android app for processing.

public static void main(String[] args) {

    File file = new File("res/raw/textfile.txt");
    
    FileInputStream fis = null;
    BufferedInputStream bis = null;
    DataInputStream dis = null;

    try {
      fis = new FileInputStream(file);
      bis = new BufferedInputStream(fis);
      dis = new DataInputStream(bis);

      while (dis.available() != 0) {
              // Do something with file
          Log.d("GAME", dis.readLine()); 
      }

      fis.close();
      bis.close();
      dis.close();

    } catch (FileNotFoundException e) {
      e.printStackTrace();
    } catch (IOException e) {
      e.printStackTrace();
    }
  }

I have tried different path syntax but always get a java.io.FileNotFoundException error. How can I access /res/raw/textfile.txt for processing? Is File file = new File("res/raw/textfile.txt"); the wrong method in Android?

***** Answer: *****

// Call the LoadText method and pass it the resourceId
LoadText(R.raw.textfile);
       
public void LoadText(int resourceId) {
    // The InputStream opens the resourceId and sends it to the buffer
    InputStream is = this.getResources().openRawResource(resourceId);
    BufferedReader br = new BufferedReader(new InputStreamReade开发者_运维知识库r(is));
    String readLine = null;
    
    try {
        // While the BufferedReader readLine is not null 
        while ((readLine = br.readLine()) != null) {
            Log.d("TEXT", readLine);
        }

        // Close the InputStream and BufferedReader
        is.close();
        br.close();

    } catch (IOException e) {
        e.printStackTrace();
    }
}

Note this will return nothing, but will print the contents line by line as a DEBUG string in the log.

If you have a file in res/raw/textfile.txt from your Activity/Widget call:

getResources().openRawResource(...) returns an InputStream

The dots should actually be an integer found in R.raw... corresponding to your filename, possibly R.raw.textfile (it's usually the name of the file without extension)

new BufferedInputStream(getResources().openRawResource(...)); then read the content of the file as a stream
