QR Code Scanner App in Android Studio - With Free Source Code

QR Code Scanner App in Android Studio - With Free Source Code



Let's get started with QR Code Scanner App in Android Studio. Also, I am going to give you the Source code of this QR Code Scanner.

I will build this QR Code Scanner App with the help of the Github Library the Name is Code Scanner:

In this library, we have the features like this:
  • Enable Portrait and Landscape orientation
  • With Auto Focus and Flash control
  • And with the Front and Back Camera
  • This is also customizable and Kotlin Friendly
  • Also, Able us to Touch to focus.
So, without wasting the time let's begin,


First Add this Dependency to your build.gradle (app level module)

            dependencies {
                    implementation 'com.budiyev.android:code-scanner:2.1.0'
            }

And then add the Camera permission in the AndroidManifest File.

<uses-permission android:name="android.permission.CAMERA"/>

And After copy the Code in Dashboard Activity:

<com.budiyev.android.codescanner.CodeScannerView
        android:id="@+id/scanner_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:autoFocusButtonColor="@android:color/white"
        app:autoFocusButtonVisible="true"
        app:flashButtonColor="@android:color/white"
        app:flashButtonVisible="true"
        app:frameColor="@android:color/white"
        app:frameCornersSize="50dp"
        app:frameCornersRadius="0dp"
        app:frameAspectRatioWidth="1"
        app:frameAspectRatioHeight="1"
        app:frameSize="0.75"
        app:frameThickness="2dp"
        app:maskColor="#77000000"/>

And Next Code is in DashboardActivity.java

public class DashboardActivty.java extends AppCompatActivity {
    private CodeScanner mCodeScanner;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_dashboard);
        CodeScannerView scannerView = findViewById(R.id.scanner_view);
        mCodeScanner = new CodeScanner(this, scannerView);
        mCodeScanner.setDecodeCallback(new DecodeCallback() {
            @Override
            public void onDecoded(@NonNull final Result result) {
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        Toast.makeText(MainActivity.this, result.getText(), Toast.LENGTH_SHORT).show();
                    }
                });
            }
        });
        scannerView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                mCodeScanner.startPreview();
            }
        });       
    }

    @Override
    protected void onResume() {
        super.onResume();
        mCodeScanner.startPreview();
    }

    @Override
    protected void onPause() {
        mCodeScanner.releaseResources();
        super.onPause();
    }
}
