File on Android

Hi, I'm trying to read a file on Android. This is my code:

var inputXml = Titanium.Filesystem.getFile('/sdcard/input.xml');
if(inputXml.exist)
{
    alert("Yes");
}
else
{
    alert("No");
}

Always show "No" Here is the adb shell output:

#cd /sdcard
#ls
input.xml

I've tried another way. This is the second code

var inputXml = Titanium.Filesystem.getFile(Titanium.Filesystem.externalStorageDirectory,'input.xml');
if(inputXml.exist)
{
    alert("Yes");
}
else
{
    alert("No");
}

Here is the output: The firse alert shows "file:///mnt/sdcard/com.myApp.testApp/input.xml" The second alert shows "No"

Here is the adb shell output:

#cd /mnt/sdcard/com.myApp.testApp/
#ls
input.xml

I can't understand the reason... Someone could help me?

try:

var file = Titanium.Filesystem.getFile(Titanium.Filesystem.externalStorageDirectory, '../input.xml');

externalStorageDirectory is your app's dir, e.g. sdcard/com.your.app/ --u

It doesn't work...always the same

You need to use exists() instead of exist in this line:

if(inputXml.exists())
