saveToPictures is depricated.

use object of GPUImageView and capture as bitmap.

Bitmap bitmap = gpuImageView.capture();

now save bitmap as image in any of location.

for save image , use this :

private void saveImage() {

    String FileName = System.currentTimeMillis() + ".jpg";
    File path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
    File file = new File(path, "GPUImage" + "/" + FileName);
    file.getParentFile().mkdirs();`

    FileOutputStream out = null;
    Bitmap bitmap = mGPUImageView.getGPUImage().getBitmapWithFilterApplied();
    try {
        out = new FileOutputStream(file);
        bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);

    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        try {
            if (out != null) {
                out.close();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

}`
