Reading a textfile using InputStream

try this

import android.app.Activity;import android.os.Bundle;import android.widget.Toast;import java.io.*;public class FileDemo1 extends Activity {    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        try {            playWithRawFiles();        } catch (IOException e) {            Toast.makeText(getApplicationContext(), "Problems: " + e.getMessage(), 1).show();        }    }    public void playWithRawFiles() throws IOException {              String str = "";        StringBuffer buf = new StringBuffer();                    InputStream is = this.getResources().openRawResource(R.drawable.my_base_data);        try {            BufferedReader reader = new BufferedReader(new InputStreamReader(is));            if (is != null) {                                            while ((str = reader.readLine()) != null) {                        buf.append(str + "\n" );                }                            }        } finally {            try { is.close(); } catch (Throwable ignore) {}        }        Toast.makeText(getBaseContext(), buf.toString(), Toast.LENGTH_LONG).show();    }}

Use BufferedReader to read the input stream. As BufferedReader will read text from a character-input stream, buffering characters so as to provide for the efficient reading of characters, arrays, and lines. InputStream represents an input stream of bytes. reader.readLine() will read the file line by line.

BufferedReader reader = new BufferedReader(new InputStreamReader(in));StringBuilder out = new StringBuilder();String line;while ((line = reader.readLine()) != null) {    out.append(line);   // add everything to StringBuilder     // here you can have your logic of comparison.    if(line.toString().equals(".")) {        // do something    } }

                File fe=new File(abc.txt);                FileInputStream fis=new FileInputStream(fe);                byte data[]=new byte[fis.available()];                fis.read(data);                fis.close();                String str=new String(data);                System.out.println(str);
