How to take snapshot of SurfaceView in Android

Question

I am developing BarCode Scanner Application. I am Using "zxing-orient-2.1.1" library for scanning the barcode. All are Perfectly working i.e. Torch, Autofocus, Icon of Application and it's give the value of Barcode.

But, I am not able to take snapshot of barcode. I don't know where i am use Snapshot Mehod. So, anyone please help for take snapshot when barcode scan completely and save in gallery.

In this library Snapshot Function is not available. So i am making the snapshot function and placed after of Initialise Scan on scanNow method. It's take the snapshot but it's takes snapshot of mainActivity and i want barcode snapshot.

Method of Library

public void scanNow(View view) {
    try {
        ZxingOrient integrator = new ZxingOrient(Fill_details.this);
        integrator.setToolbarColor("#2979FF")       // Sets Tool bar Color
                .setInfoBoxColor("#2979FF")       // Sets Info box color
                .setInfo("Scan a code Image.")
                .setBeep(true)  // Doesn't play beep sound
                .setVibration(true)// Sets info message in the info box
                .initiateScan(Barcode.ONE_D_CODE_TYPES);
    }catch(Exception e){
        e.printStackTrace();
    }
}

public void onActivityResult(int requestCode, int resultCode, Intent intent) {
    //retrieve scan result
    ZxingOrientResult scanResult =  ZxingOrient.parseActivityResult(requestCode, resultCode, intent);
    if (scanResult != null && resultCode==RESULT_OK) {
        takeScreenshot();
        Date now = new Date();
        android.text.format.DateFormat.format("yyyy-MM-dd_hh:mm:ss", now);
        String date = now.toString();
        String time[] = date.split("G");
        String contents = intent.getStringExtra("SCAN_RESULT");
        String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
        Intent intent1 = new Intent(Fill_details.this,FinishingNSave.class);
        intent1.putExtra("Content",contents);
        intent1.putExtra("Format",format);
        intent1.putExtra("time",time[0]);
        startActivity(intent1);
    } else if (resultCode == RESULT_CANCELED) {}
}

Snapshot Method

private void takeScreenshot() {
    Date now = new Date();
    android.text.format.DateFormat.format("yyyy-MM-dd_hh:mm:ss", now);

    try {
        // image naming and path  to include sd card  appending name you choose for file
        String mPath = Environment.getExternalStorageDirectory().toString() + "/" + now + ".jpg";

        // create bitmap screen capture
        View v1 = getWindow().getDecorView().getRootView();
        v1.setDrawingCacheEnabled(true);
        Bitmap bitmap = Bitmap.createBitmap(v1.getDrawingCache());
        v1.setDrawingCacheEnabled(false);

        File imageFile = new File(mPath);

        FileOutputStream outputStream = new FileOutputStream(imageFile);
        int quality = 100;
        bitmap.compress(Bitmap.CompressFormat.JPEG, quality, outputStream);
        outputStream.flush();
        outputStream.close();

        openScreenshot(imageFile);
    } catch (Throwable e) {
        // Several error may come out with file handling or DOM
        e.printStackTrace();
    }
}

Open Screenshot

 private void openScreenshot(File imageFile) {
    Intent intent = new Intent();
    intent.setAction(Intent.ACTION_VIEW);
    Uri uri = Uri.fromFile(imageFile);
    intent.setDataAndType(uri, "image/*");
    startActivity(intent);
}

@Dilip- Yes, I am giving this permission. It's capture the Image but it's a Main Activity not Barcode Image — Himanshu Srivastava, Dec 06 '17 at 06:39
You say: "I am not able to take snapshot of barcode" - what actually is the problem? The program crashes, no file is saved, an empty file is saved, or what? Please describe your issue in detail. — Ken Y-N, Dec 06 '17 at 06:45
