this will help Here's how it works.
Step 1: Add following lines to rotate data before buildLuminanceSource(..) in decode(byte[] data, int width, int height)
code :
byte[] rotatedData = new byte[data.length];
for (int y = 0; y < height; y++) {
    for (int x = 0; x < width; x++)
        rotatedData[x * height + height - y - 1] = data[x + y * width];
}
int tmp = width;
width = height;
height = tmp;

PlanarYUVLuminanceSource source = activity.getCameraManager().buildLuminanceSource(rotatedData, width, height);
rect.left = rect.left * cameraResolution.y / screenResolution.x;
rect.right = rect.right * cameraResolution.y / screenResolution.x;
rect.top = rect.top * cameraResolution.x / screenResolution.y;
rect.bottom = rect.bottom * cameraResolution.x / screenResolution.y;
//remove the following
if (width < height) {
  Log.i(TAG, "Display reports portrait orientation; assuming this is incorrect");
  int temp = width;
  width = height;
  height = temp;
}
camera.setDisplayOrientation(90);

hope this fix your issue You could follow the instruction in the link to set up ZXing in your application. If not, you could download ZXing library into your computer and add it in libs folder. After that, you could use ZXing in your app in Portrait mode or set it in a layout by using CompoundBarcodeView.
Please refer my project. I am using ZXing for it. Hope this help!
