First of all, i gave the application all superuser permission(i'm using my rooted Galaxy S), then i want to create a file in /system using this code:

```
try 
{
 File file = new File("/system/", "test.prop");
 file.createNewFile();
 }

```

Unfortunately, the file is not created. What could be the source of the problem?

Thanks for helping.
