Access resource files in Android
android, file, java, resources
Solution
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
Problem
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 InputStreamReader(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.
