Yet another barcode scanner for Android. As if there weren't enough.

This one is free, without any ads and open source.

Works in portrait and landscape orientation, can read inverted codes, comes in Material Design and can also generate barcodes.

Binary Eye uses the ZXing-C++ ("Zebra Crossing") barcode scanning library.

ZXing can read the following barcode formats:

• AZTEC
• CODABAR
• CODE 39
• CODE 93
• CODE 128
• DATA MATRIX
• EAN 8
• EAN 13
• ITF
• MAXICODE (partial)
• PDF417
• QR CODE
• Micro QR Code
• RSS 14
• RSS EXPANDED
• UPC A
• UPC E
• UPC EAN EXTENSION

ZXing can generate the following barcode formats:

• AZTEC
• CODABAR
• CODE 39
• CODE 128
• DATA MATRIX
• EAN 8
• EAN 13
• ITF
• PDF 417
• QR CODE
• UPC A

You can invoke Binary Eye with a web URI intent from anything that can open URIs. There are two options:

1. binaryeye://scan
2. http(s)://markusfisch.de/BinaryEye

If you want to get the scanned contents, you can add a ret query argument with a (URL encoded) URI template. For example:

http://markusfisch.de/BinaryEye?ret=http%3A%2F%2Fexample.com%2F%3Fresult%3D{RESULT}

Supported symbols are:

• RESULT - scanned content
• RESULT_BYTES - raw result as a hex string
• FORMAT - barcode format

You can also use Binary Eye from other apps by using the com.google.zxing.client.android.SCAN Intent with startActivityForResult() like this:

startActivityForResult(
	Intent("com.google.zxing.client.android.SCAN"),
	SOME_NUMBER
)

And process the result in onActivityResult() of your Activity:

override fun onActivityResult(
	requestCode: Int,
	resultCode: Int,
	data: Intent?
) {
	when (requestCode) {
		SOME_NUMBER -> if (resultCode == RESULT_OK) {
			val result = data.getStringExtra("SCAN_RESULT")
			…
		}
	}
}

If you're using AndroidX, this would be the new, recommended way:

class YourActivity : Activity() {
	private val resultLauncher = registerForActivityResult(StartActivityForResult()) { result ->
		if (result.resultCode == Activity.RESULT_OK) {
			val scan = result.data?.getStringExtra("SCAN_RESULT")
			…
		}
	}

	fun openScanner() {
		resultLauncher.launch(Intent("com.google.zxing.client.android.SCAN"))
	}
}
