Need Help with Android Barcode Scanner Integration

[kemiy]

Hey everyone,

I'm currently working on integrating a barcode scanner into my Android application, and I'm encountering some challenges. I've been researching various libraries and APIs, but I'm struggling to find one that fits my requirements perfectly. Specifically, I need a solution that is reliable, efficient, and easy to implement within my existing codebase.

If anyone has experience with integrating barcode scanners into Android apps or can recommend a reliable library or API, I would greatly appreciate your insights and recommendations. Any tips, suggestions, or even code snippets would be incredibly helpful.

Thanks in advance for your assistance!

Hi there!

You're right that there are quite a few libraries and APIs available for integrating barcode scanning functionalities into your Android app. Let's review some that have proven reliable and efficient:

1. **Google's Mobile Vision API:** Provided by Google, this API has great accuracy and includes built-in barcode scanning functionality. The Google Play Services SDK includes the mobile vision API. However, Mobile Vision is now integrated with ML Kit which new developers are encouraged to use.

2. **ZXing (Zebra Crossing):** This is possibly one of the most popular open-source libraries for barcode scanning in Android applications. The downside is that integration can be a bit challenging, and it takes a significant amount of memory.

3. **ZBar:** This is another open-source software suite for reading bar codes from various sources, particularly mobile devices. It's a bit lighter than ZXing, but it may not be as good in terms of recognition rates.

4. **Scandit:** This is a commercial product and provides excellent scanning capabilities. Scandit has a proprietary barcode scanning library, which is very fast and reliable. But unlike the others, it's not free.

Code-wise, here's a simple implementation using ZXing:

```java
import com.google.zxing.integration.android.IntentIntegrator;
import com.google.zxing.integration.android.IntentResult;

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

new IntentIntegrator(this).initiateScan();
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
if(result != null) {
if(result.getContents() == null) {
Toast.makeText(this, "Cancelled", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(this, "Scanned: " + result.getContents(), Toast.LENGTH_LONG).show();
}
} else {
super.onActivityResult(requestCode, resultCode, data);
}
}
}
```

When choosing a library or API, remember to consider the specific needs of your project, such as cost, accuracy, and ease of integration.
