Android File.listFiles does not show all the files inside the directory

Question

Hi,

I am using Android Emulator 2.2 version to develop a small application. I am supposed to list all the image files(jpg) files under a directory. I copied the files to "/data" through ADB puash command.

Example : /data/1.jpg

Now I create a File object with the directory path as input and call listFiles api.

File dir = new File(dirPath);
File[] filelist = dir.listFiles();

But the fileList does not contain the image file(1.jpg).

But strangely, If I create a ImageView with hardcoded path "/data/1.jpg", I could see the image getting drawn.

Can some one help me.... where could be the problem

Thanks, Kowndinya

public int PopulateList(final String dirPath)
{
m_CurrentDirectory = new File(dirPath);
_namelist.clear();
_pathlist.clear();

File[] fileList = m_CurrentDirectory.listFiles(imFilter);
if (fileList != null)
{
for ( int i = 0;i<fileList.length;i++)
{
_namelist.addElement(fileList[i].getName());
_pathlist.addElement(fileList[i].getAbsolutePath()); 
}
}
notifyDataSetChanged();
return 0;
}

imFilter is an filenamefilter that accepts only files with jpg extension. But if I put break point in the imFilter code, break point does not event hit.

Output of adb shell ls -l /data:

Answer 1

Can you plz show full code and show the command output "adb shell ls -l /data"

Answer 2

I explore that code, and see, trouble is in permission. As U can see below, U can't read that dir.Find another dir to collect your files.

**Can read dir:** 
/dev =true
/root =false
/data =false
/default.prop =true
/init =false
/init.rc =false
/proc =true
/sbin =false
/sys =true
/system =true
/etc =true
/d =false
/mnt =true
/acct =true
/sdcard =true
/cache =false
/config =false

and that U can see from "ls -l" command. explain what does mean
