All issues with permission come from using the default sdcard image. So simply create a new sdcard image.

To do this, open AVD Manager in Android Studio, click on "Show Advanced Settings" on the bottom of the screen and then create a new sdcard image. Both options are marked on the image below.

After this you will be able to use console to create images, push files, and other tasks.

if you are using Eclipce then follow these steps

goto Window->AVD manager->select the AVD for which you want to create the sdcard then click edit on sd card panel give the size->edit AVD

Menu-->Dev Tools-->Media Scanner

you have to set the permission in manifest before you do so.

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-      
permission>

Include this to create a directory.

String extStorageDirectory = "/mnt/sdcard/Foldername/";
File myNewFolder = new File(extStorageDirectory); 
if ( !myNewFolder.exists() ) 
   myNewFolder.mkdir();

This method can be used to copy a file from source to destination. public void copy(File src, File dst) throws IOException { InputStream in = new FileInputStream(src); OutputStream out = new FileOutputStream(dst);

    // Transfer bytes from in to out
    byte[] buf = new byte[1024];
    int len;
    while ((len = in.read(buf)) > 0) {
        out.write(buf, 0, len);
    }
    in.close();
    out.close();
}
