createDiarectoryandSaveImage()  :- 

private void createDirectoryAndSaveFile(Bitmap imageToSave) {
    ts = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date()).toString();
    File direct = new File(Environment.getExternalStorageDirectory() + "/10AM");

    if (!direct.exists()) {
        File wallpaperDirectory = new File("/sdcard/10AM/");
        wallpaperDirectory.mkdirs();
    }

     file = new File("/sdcard/10AM/", ts+".png");
    if (file.exists()) {
        file.delete();
    }
    try {
        FileOutputStream out = new FileOutputStream(file);
        imageToSave.compress(Bitmap.CompressFormat.JPEG, 100, out);
        out.flush();
        out.close();
    } catch (Exception e) {
        e.printStackTrace();

    Intent sharingIntent = new Intent(Intent.ACTION_SEND);
    sharingIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
    sharingIntent.setType("image/*");
    sharingIntent.putExtra(Intent.EXTRA_STREAM, imagePath);
    sharingIntent.putExtra(Intent.EXTRA_TEXT, "http://codepath.com");
    startActivity(Intent.createChooser(sharingIntent, "Share Image Using"));
}
