Question

I was referring to this http://developer.android.com/guide/topics/data/data-storage.html#filesInternal for write file in internal memory. Where do I check the file? For an example the guide code:

String FILENAME = "hello_file";
String string = "hello world!";

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

Where do I go and check the file hello_file, since the guide didn’t give the path?

If you have created the file in the EXTERNAL_STORAGE, then you can check the same in the sdcard by browsing through the sdcard. Or check in the /mnt/sdcard/... in the File explorer tab.

If you have created the file in the INTERNAL_STORAGE then you can check in the /data/data... path. But you wont be able to browse /data/data path if your phone is not rooted.
