I have tried that and i have stored that file by creating the files folder in the android app itself.Not on the sd card or somewhere else. — user1662334, Sep 19 '12 at 10:38

If I write a file in the internal storage like described in the Android dev-tut (Link) to my applications private storage, Iam able to verify with you code that the file has been written successfully!

So the verification code should be all right. Maybe the way you are writing the file is wrong. Here is my code snippet:

String FILENAME = "Android.mk";
String string = "hello world";

FileOutputStream fos = openFileOutput(FILENAME, getBaseContext().MODE_PRIVATE);
fos.write(string.getBytes());
fos.close();

File file = getBaseContext().getFileStreamPath("Android.mk");
if (file.exists()) {
    Toast.makeText(this, "Android.mk exist", Toast.LENGTH_LONG).show();
}
