can you help me in seemless integration with PayUmoney payment Gateway in android
also if you have any sample of seemless integration please share
i have tried like this but showing me error of Marchentkey and salt is incorrect but i copied both from my account
below is code detail

}
}
The function onPageFinished() does not get invoked. The respective intent is not being called, when the payment succeeds. The webview just redirects to the success page. Can anyone help me in resolving this error? I also need to add the bundle variables to the db, on redirecting to success page.

Document Missing - Google Cloud Print

I am trying to use google cloud print with my project on android studio to print out a pdf file. I am storing the file in the assets folder of the project and when I go to print it say "Document Missing". this is my java code:
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void onPrintClick(View v) {
String path = Environment.getExternalStorageDirectory().getAbsolutePath()
+ "/monsoon.pdf";
File file = new File(path);
if (file.exists()) {
Uri uri = Uri.fromFile(file);
Intent printIntent = new Intent(this, PrintDialogActivity.class);
printIntent.setDataAndType(uri, "application/pdf");
printIntent.putExtra("title", "Gaurang");
startActivity(printIntent);
} else {
Toast.makeText(getApplicationContext(), "No file",
Toast.LENGTH_SHORT).show();
}
}
}
and Here is Android Code for Google Cloud Print with some modification on class PrintDialogJavaScriptInterface...ie. applying annotations #JavascriptInterface
public class PrintDialogActivity extends Activity {

view.loadUrl("javascript:window.addEventListener('message',"

}
}
}
}

I see two things that might be wrong.
In the getContent method you have return "";
when you send the PDF in the onPrintClick method, you are not converting the PDF to base64.
I hope I spotted something interesting :)

Barcode scanning issue

I am working on barcode scanning on button click to increment the quantity counted field by one of a table when the scanning result matches with the item number field of the table. If the scan result matches item number it should update the quantity counted of that row. I am unable to get the scan result itself. Getting NullPointerException.
This is my code.

c.moveToFirst();

Toast.LENGTH_SHORT).show();
} catch (Exception e) {

}
}
I have just tried to display scan result and if it matches itemnumber it will display the corresponding quantity in that row as shown in code above. But as of now not even scan result is displaying. Help me.. Also say how to increment the quantity by one and update it in db.

Try to use the zxing library by extending the CaptureActivity Class.
public class ScannerData extends CaptureActivity {
Handler handler = null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_scanner);
}
#Override
public void handleDecode(final Result rawResult, Bitmap barcode,
float scaleFactor) {
// TODO Auto-generated method stub
handler = getHandler();
handler.sendEmptyMessageDelayed(R.id.restart_preview,
CaptureActivity.BULK_MODE_SCAN_DELAY_MS);
String mQrcode = rawResult.getText().toString();
}
}
Use the code like this.
You can get the qr-code here
String mQrcode = rawResult.getText().toString();
In Xml you need to include capture.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent">
