Android版本的SDK不能直接从图像文件中读取，但它可以使用类似于以下的代码从位图中读取。

Barcode barcode = new Barcode();

// Load your image file into a bitmap

int width = bitmap.getWidth();
int height = bitmap.getHeight();

byte[] rawBytes = new byte[width * height * 4];
int index = 0;

for (int y = 0; y < height; y++) {
    for (int x = 0; x < width; x++) {
        int colour = bitmap.getPixel(x, y);
        int red = (colour >> 16) & 0xff;
        int green = (colour >> 8) & 0xff;
        int blue = colour & 0xff;
        int alpha = 0;
        int rawIndex = index * 4
        rawBytes[rawIndex++] = (byte) red ;
        rawBytes[rawIndex++] = (byte) green;
        rawBytes[rawIndex++] = (byte) blue;
        rawBytes[rawIndex++] = (byte) alpha;

        index++;
    }
}

int n = barcode.ScanBarCodeFromRGBABitmap(bitmap.getWidth(), bitmap.getHeight(), rawBytes);

if (n > 0)
    strBarcode = barcode.GetBarString(1);
