Barcode Reader - Google Mobile Vision
===================
Android Barcode Reader library using **Google Mobile Vision.** This library is built on top of google mobile vision sample adding improvements and fixing few bugs.
[  ](https://bintray.com/androidhive-info/maven/barcode-reader/_latestVersion)
[](https://www.androidhive.info/2017/07/android-implementing-preferences-settings-screen/)
How to Use
-------------
1. Include the barcode reader dependency in app's **build.gradle**
```gradle
dependencies {
// google mobile vision
implementation 'com.google.android.gms:play-services-vision:11.0.2'
// barcode reader
implementation 'info.androidhive:barcode-reader:1.1.5'
}
```
2. Add the barcode reader fragment to your activity
```xml
```
3. Implement your activity from BarcodeReader.BarcodeReaderListener and override the necessary methods.
```java
public class MainActivity extends AppCompatActivity implements BarcodeReader.BarcodeReaderListener {
private BarcodeReader barcodeReader;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
barcodeReader = (BarcodeReader) getSupportFragmentManager().findFragmentById(R.id.barcode_fragment);
}
@Override
public void onScanned(Barcode barcode) {
// play beep sound
barcodeReader.playBeep();
}
@Override
public void onScannedMultiple(List list) {
}
@Override
public void onBitmapScanned(SparseArray sparseArray) {
}
@Override
public void onScanError(String s) {
}
@Override
public void onCameraPermissionDenied() {
Toast.makeText(getApplicationContext(), "Camera permission denied!", Toast.LENGTH_LONG).show();
}
}
```
Adding Barcode Reader in Fragment
----
In fragment the barcode reader can be added easily but the scanner listener barcodeReader.setListener() has to
be set manually.
Check the example fragment code in BarcodeFragment.java and BarcodeFragmentTestActivity.java
https://github.com/ravi8x/Barcode-Reader/tree/master/example/src/main/java/info/androidhive/barcodereader
Adding Scanner Overlay Scanning Indicator
----
The overlay animation indicator displays a horizontal line animating from top to bottom. This will be useful to to show some cool animation to indicate scanning progress.
To use it, add the info.androidhive.barcode.ScannerOverlay on top of barcode reader fragment using Relative or Frame layout.
```xml
```
Additional Options
-------------
XML attribute for **Barcode Reader**
auto_focus - boolean, turn on/off auto focus. Default is true
use_flash - boolean, turn on/off flash. Default is false
XML attribute for **Scanner Overlay** Indicator
square_width - Width of transparent square
square_height - Height of transparent square
line_color - Horizontal line color
line_speed - Horizontal line animation speed
----
JAVA Methods
- **Play beep sound**
You can play the **beep** sound when the barcode is scanned. This code is usually called in onScanned() callback.
```java
@Override
public void onScanned(final Barcode barcode) {
Log.e(TAG, "onScanned: " + barcode.displayValue);
barcodeReader.playBeep();
});
}
```
- **Change beep sound**
You can change the default **beep** sound by passing the file name. You beep file should be in project's **assets** folder.
```java
barcodeReader.setBeepSoundFile("shutter.mp3");
```
- **Pause scanning**
The scanning can be paused by calling pauseScanning() method.
```java
barcodeReader.pauseScanning();
```
- **Resume Scanning**
The scanning can be resumed by calling resumeScanning() method.
```java
barcodeReader.resumeScanning();
```
## Know Issues
- Camera stream is not smooth. It's because of camera resolution.
- Sometimes screen turns black after Camera permission is granted.
