Question

i need to list only the files present on a sdcard.

With the following code:

File sdcard=new File(Environment.getExternalStorageDirectory().getAbsolutePath());
if(sdcard.isDirectory()){
      String files[]=  sdcard.list();
      for(int i=0;i<files.length;i++){
            File f=new File(files[i]);

            if(!f.isDirectory())
                Log.d("FILES",files[i]);
      } 
}

I see also in the log the subdirectories. What am i doing wrong?

Answer 1

Try this:

if(sdcard.isDirectory()){
    File[] files =  sdcard.listFiles();
    for (File f : files){
        if(!f.isDirectory())
            Log.d("FILES",f.getName());
    } 
}  

The key difference is sdcard.files() vs sdcard.listFiles().
