Answer 1

I used this code to read a text file in SD card,

public class ReadFileSDCardActivity extends Activity {  
    /** Called when the activity is first created. */  
    @Override  
    public void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.main);  

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

        File dir = Environment.getExternalStorageDirectory();  
        //File yourFile = new File(dir, "path/to/the/file/inside/the/sdcard.ext");  

        //Get the text file  
        File file = new File(dir,"text.txt");  
        // i have kept text.txt in the sd-card  

        if(file.exists())   // check if file exist  
        {  
              //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');  
                }  
            }  
            catch (IOException e) {  
                //You'll need to add proper error handling here  
            }  
            //Set the text  
            tv.setText(text);  
        }  
        else  
        {  
            tv.setText("Sorry file doesn't exist!!");  
        }  
     }  
}
