Can't scan code-128 format as Android Intent

[Mariano Cano]

Hi, i'm using the barcode Scanner as an Intent. Using this code:

 Intent intent = new Intent("com.google.zxing.client.android.SCAN");
 intent.putExtra("SCAN_MODE", "PRODUCT_MODE");
 context.startActivityForResult(intent, 0);

But It takes too long to recognize the code. But the real problem is that always return a random number, with the wrong format: UPC_E

The strange part is when I start the Barcode Scanner application recognize the barcode quickly and correctly, with format: CODE-128.

 String contents = intent.getStringExtra("SCAN_RESULT");
 String format = intent.getStringExtra("SCAN_RESULT_FORMAT");

This scans fine as Code 128 (says 001ade8f466a). What is happening is that you're not successfully scanning it with your phone. Eventually you get a mis-read, and commonly that will be for some phantom UPC-E code.

The reason you are not reading code 128 is right there -- you're scanning for product formats, and Code 128 is not one of those.

I removed the line:

intent.putExtra("SCAN_MODE", "PRODUCT_MODE");

And still won't read it.

I've also tried adding this with no luck:

intent.putExtra("SCAN_FORMATS", "CODE_39,CODE_93,CODE_128,DATA_MATRIX,ITF,CODABAR,EAN_13,EAN_8,UPC_A,QR_CODE");

Is there any option that I need to use?

Why not

intent.putExtra("SCAN_FORMATS", "CODE_128");

This worked pretty cool for me. Thanks Sean Owen.
