Barcode Scan in Android

1. First Add this in yr Gradle

compile 'me.dm7.barcodescanner:zxing:1.9.8'

compile 'com.edwardvanraak:MaterialBarcodeScanner:0.0.6-ALPHA'

2.Secondly Add this in Activity

public static final String BARCODE_KEY = "BARCODE";

private Barcode barcodeResult;

Use This Method 

private void startScan() {

final MaterialBarcodeScanner materialBarcodeScanner = new MaterialBarcodeScannerBuilder()
            .withActivity(this)
            .withEnableAutoFocus(true)
            .withBleepEnabled(true)
            .withBackfacingCamera()
            .withCenterTracker()
            .withText("Scanning...")
            .withResultListener(new MaterialBarcodeScanner.OnResultListener() {
                @Override                public void onResult(Barcode barcode) {
                    barcodeResult = barcode;
                                                   

                    String Get_code_Text = barcode.rawValue.toString();
                   

                }
            })
            .build();
    materialBarcodeScanner.startScan();
}

barcode scanner in android programmatically

Simple Usage

1.) Add camera permission to your AndroidManifest.xml file:

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

2.) A very basic activity would look like this:

public class SimpleScannerActivity extends Activity implements ZXingScannerView.ResultHandler {
    private ZXingScannerView mScannerView;

    @Override
    public void onCreate(Bundle state) {
        super.onCreate(state);
        mScannerView = new ZXingScannerView(this);   // Programmatically initialize the scanner view
        setContentView(mScannerView);                // Set the scanner view as the content view
    }

    @Override
    public void onResume() {
        super.onResume();
        mScannerView.setResultHandler(this); // Register ourselves as a handler for scan results.
        mScannerView.startCamera();          // Start camera on resume
    }

    @Override
    public void onPause() {
        super.onPause();
        mScannerView.stopCamera();           // Stop camera on pause
    }

    @Override
    public void handleResult(Result rawResult) {
        // Do something with the result here
        Log.v(TAG, rawResult.getText()); // Prints scan results
        Log.v(TAG, rawResult.getBarcodeFormat().toString()); // Prints the scan format (qrcode, pdf417 etc.)

        // If you would like to resume scanning, call this method below:
        mScannerView.resumeCameraPreview(this);
    }
}

Write CSV files onto SD Card Storage

add this permission in manifest

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

This example shows how to create a CSV file on removable storage in Android. CSV files are a convenient storage format for data to be easily viewed in programs like Excel or OpenOffice.

In this example, my goal is to create a CSV file having the following text:

--------------------------------------------- FirstParam SecondParam ThirdParam 0.31 5.2 7 0.31 5.2 7.1 0.31 5.2 7.2

Add this code to open a new file called "mydata.csv" on the SD card:

import java.io.File; import java.io.FileWriter; import java.io.IOException; import android.os.Environment; --------------------------------------------- FileWriter writer; File root = Environment.getExternalStorageDirectory(); File gpxfile = new File(root, "mydata.csv");

Use this routine to write the csv headers:

private void writeCsvHeader(String h1, String h2, String h3) throws IOException {    String line = String.format("%s,%s,%s\n", h1,h2,h3);    writer.write(line);  }

Use this routine to write CSV values to the file:

private void writeCsvData(float d, float e, float f) throws IOException {   String line = String.format("%f,%f,%f\n", d, e, f);   writer.write(line); }

Write the header and data lines like this:

try {         writer = new FileWriter(gpxfile);         writeCsvHeader("FirstParam","SecondParam","ThirdParam");         writeCsvData(0.31f,5.2f,7.0f);         writeCsvData(0.31f,5.2f,7.1f);         writeCsvData(0.31f,5.2f,7.2f); } catch (IOException e) {             e.printStackTrace(); }

Quick note: adding "f" to the end of the constant number above tells Java you explicitly want to pass the value as a float, instead of a double.

Don't forget to close the file:

writer.flush(); writer.close();

How to enable/disable bluetooth programmatically in android

Add the following permissions into your manifest file:

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

To Enable BLUETOOTH Use This Code.

//Enable bluetooth
BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();    
if (!mBluetoothAdapter.isEnabled()) {
    mBluetoothAdapter.enable(); 
}else{Toast.makeText(getApplicationContext(), "Bluetooth Al-Ready Enable", Toast.LENGTH_LONG).show();} 
//Disable bluetooth
BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();    
if (!mBluetoothAdapter.isEnabled()) {
    mBluetoothAdapter.disable(); 
}
