I work on the project android application .. My application uses file.txt for the purposes of a process. I found an error opening trace file:

 No such file or directory (2) when running my application.

The manifest I have complete internet access permissions. I save the file.txt in res/raw/file.txt there is no error in the code line. I use a OS 4.1 (jelly bean) android"sdk" 21

Any help would be appreciated.

then I tried it once again by using a virtual android 4.2.2 ... but the results are also errors

public List<String> read() {
    List<String> ls = new ArrayList<String>();
    try {          
        InputStream inputStream = this.getClass().getClassLoader().getResourceAsStream("res/raw/katadasar.txt");
        InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
        BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
        StringBuffer stringBuffer = new StringBuffer();
        String strLine;
        //Read File Line By Line
        while ((strLine = bufferedReader.readLine()) != null) {
        // Print the content on the console
        // System.out.println(strLine);
        ls.add(strLine.trim().toLowerCase());
        }
        //Close the input stream
        inputStreamReader.close();
        } catch (Exception e) {//Catch exception if any
        System.err.println("Error: " + e.getMessage());
        }
        return ls;
}

要在原始文件夹中打开文件，您可以尝试以下操作：

InputStream is = ctx.getResources().openRawResource(R.raw.katadasar);
InputStreamReader isr = new InputStreamReader(is);

此外，您应该更改您的 catch 中的代码：

catch (Exception e) {//Catch exception if any
    System.err.println("Error: " + e.getMessage());
}

为此，打印正确的错误：

catch (Exception e) {//Catch exception if any
    Log.e("YourTag", "Error:" +  e.getLocalizedMessage() );
}

尝试上面的代码（带有正确的错误logcat输出），如果它不起作用，请更新logcat输出以尝试定位错误
