I used the following code to create a file:
FileOutputStream fos = app.openFileOutput(fileName, Context.MODE_WORLD_WRITEABLE);
fos.write(content.getBytes());
fos.close();
the file is create on the emulator but it is not created on my device (Samsung Galaxy Tab sdk 2.3).
There are no exception and no logs.
If I use getFilesDir I get a path that doe not exists. /data/data/it.xyz.xyz/files.
It should definitely work. How are you checking if the file actually exists? What I mean is: without root access when you use e.g. a File Manager you won’t be able to access the /data/.. folders, but you can access that file from your own application.
