# Binary Eye

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

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++][zxing_cpp] ("Zebra Crossing") barcode
scanning library.

## Deep Links and Intents

### Deep Links

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

1. [binaryeye://scan](binaryeye://scan)
2. [http(s)://markusfisch.de/BinaryEye](http://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}](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
* `META` - the meta data, if available

### SCAN Intent

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

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

And process the result in [onActivityResult()][on_activity_result] of your
`Activity`:

```kotlin
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][intent_result]:

```kotlin
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"))
	}
}
```
