}
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

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 :)

The Broadcast Receiver didn't start after starting the activity class

I am assigned a project on vehicle tracking system to be developed as an android app.
Project Brief:
A vehicle driver is been given a GPRS powered android OS installed phone so that the location is tracked. The assumption is that all route coordinates (latitude & longitude) are already stored in DB.Such that when the driver crosses a particular place, there should be an alert (change of status) in the DB.In this way, the tracking shall be made efficiently.
My Issue:
I have developed the program but unable to get it executed. I am wondering if my coding is totally wrong or I had left something in between. I have attached/pasted the program for your consideration.
I shall be too glad to receive inputs from you & see the dawn of the project's execution.
You shall reach me at inbasharu#gmail.com
Alternately, if you are magnanimous in helping me outright do buzz me # 9659709092/7305738685
