If you want to recieve the file you have to write it to the external storage and you must request the WRITE_EXTERNAL_STORAGE permission in your manifest file:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
When saving a file to internal storage, you can acquire the appropriate directory as a File by calling getFilesDir() or getCacheDir():
File file = new File(context.getFilesDir(), filename);
