		String strText = "My text";

                // MODE_APPEND, MODE_WORLD_READABLE, MODE_WORLD_WRITEABLE
		// create new file or rewrite existing
                FileOutputStream fos = openFileOutput(MYFILE, getApplicationContext().MODE_PRIVATE);
                // append to file
                FileOutputStream fos = openFileOutput(MYFILE, getApplicationContext().MODE_APPEND);

		fos.write(strText.getBytes());
		fos.close();					
	} catch (IOException e) {
		e.toString();
    }	

Write to file Java example

try {
// new file    
BufferedWriter out = new BufferedWriter(
    		new FileWriter("outfilename"));
    // append text 
   BufferedWriter out = new BufferedWriter(new FileWriter("outfilename", true));
    out.write("some text");
    out.close();
 } catch (IOException e) {
   e.toString();
}			

Environment.getExternalStorageDirectory()+ File.separator

Boolean canWrite =	Environment.getExternalStorageDirectory().canWrite() ;
if(canWrite){
File f = new File(Environment.getExternalStorageDirectory()
                        + File.separator + "my_image.jpg")
f.createNewFile();
}else{

}

Try insert + before R.drawable.xxxx

// error
InputStream is = context.getResources().openRawResource(R.drawable.app_sample_code);

// ok
InputStream is = context.getResources().openRawResource(+R.drawable.app_sample_code);

Put your sglite database to Android Eclipse project folder named Assets.
On device will copy database file to application folder as this example:

 public void createDatabase(Context myContext) throws IOException {
    String sPackName = myContext.getPackageName();
    InputStream assetsDB = myContext.getAssets().open("myDatabase");
    OutputStream dbOut = new FileOutputStream("/data/data/"+sPackName+"/database");
 
    byte[] buffer = new byte[1024];
    int length;
    while ((length = assetsDB.read(buffer))>0){
      dbOut.write(buffer, 0, length);
    }
 
    dbOut.flush();
    dbOut.close();
    assetsDB.close();
}

Read file from URL to array of byte and convert to UTF-8 String Android examle source code.

URL urlLoc = new URL("//myweb.com/myfile.html");
URLConnection conexion = urlLoc.openConnection();
conexion.setConnectTimeout(4000);
conexion.setReadTimeout(1000);
conexion.connect();

// downlod the file
InputStream input = new BufferedInputStream(urlLoc
		.openStream());

StringBuffer responseBuffer = new StringBuffer();
byte[] byteArray = new byte[1024];
while (input.read(byteArray) != -1)
 {   
        String res = new String(byteArray, "UTF-8");
        responseBuffer.append(res);
        byteArray = null;
        byteArray = new byte[1024];
 }

String response = responseBuffer.toString().trim();
