Answer 1

Try following method.

private void saveImageToExternalStorage(String fileName, Bitmap finalBitmap) {

    String root = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).toString();
    File myPicDirectory = new File(root + "/my_pics");
    myPicDirectory.mkdirs();

    File file = new File(myDir, fileName);
    if (file.exists())
    file.delete();
    try {
        FileOutputStream out = new FileOutputStream(file);
        finalBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out); // 90 refers to quality of image
        out.flush();
        out.close();
    }
    catch (Exception e) {
        e.printStackTrace();
    }

}

And don't forget to add permission in manifest file too.

Environment.getExternalStoragePublicDirectory will always give you the path to the primary shared/external directory. You can find more about it here .

The primary shared directory can be internal directory shared to user or external sdcard directory depending upon the manufacture of the device.

Although to get list of shared/external directory in a device above API level 19 you can make use of getExternalFilesDirs() method in context class.
