Set IO Buffer size in ImageLoaderConfiguration

[spacemase]

UIL appears to use an IO Buffer size of 8k, data seems to indicate 32k would be better performance: http://stackoverflow.com/questions/10143731/android-optimal-buffer-size

Would prefer to have an option to set in ImageLoaderConfiguration.

You can use your own value of buffer size by extending BaseImageDownloader:

public class MyImageDownloader extends BaseImageDownloader {

    private static final int MY_BUFFER_SIZE = 128 * 1024; // this is your value

    public MyImageDownloader(Context context) {
        super(context);
    }

    public MyImageDownloader(Context context, int connectTimeout, int readTimeout) {
        super(context, connectTimeout, readTimeout);
    }

    protected InputStream getStreamFromNetwork(String imageUri, Object extra) throws IOException {
        HttpURLConnection conn = createConnection(imageUri);

        int redirectCount = 0;
        while (conn.getResponseCode() / 100 == 3 && redirectCount < MAX_REDIRECT_COUNT) {
            conn = createConnection(conn.getHeaderField("Location"));
            redirectCount++;
        }

        return new BufferedInputStream(conn.getInputStream(), MY_BUFFER_SIZE);
    }

    protected InputStream getStreamFromFile(String imageUri, Object extra) throws IOException {
        String filePath = Scheme.FILE.crop(imageUri);
        return new BufferedInputStream(new FileInputStream(filePath), MY_BUFFER_SIZE);
    }
}
