8) If you see in openssl Bin folder, you will get a file with the name of debug.txt
9) Now either you can restart command prompt or work with existing command prompt
10) get back to C drive and give the path of openssl Bin folder
11) copy the following code and paste
openssl sha1 -binary debug.txt > debug_sha.txt
12) you will get debug_sha.txt in openssl bin folder
13) Again copy following code and paste
openssl base64 -in debug_sha.txt > debug_base64.txt
14) you will get debug_base64.txt in openssl bin folder
15) open debug_base64.txt file Here is your Key hash.

Cordova: How to download file and get download progress?
var assetURL = 'http://www.anywebsite.com/test.mp3';
var store = cordova.file.externalRootDirectory; // output in android: file:///storage/emulated/0/
// or
// var store = "cdvfile://localhost/persistent/";
var fileName = 'Sounds/test.mp3';
// NOTE: Sounds folder should already be there in order to download file in that folder
var fileTransfer = new FileTransfer();
fileTransfer.download(assetURL, store + fileName,
function(entry) {
console.log("Success!");
//appStart();
},
function(err) {
console.log("Error");
console.dir(err);
});
fileTransfer.onprogress = function(result){
var percent = result.loaded / result.total * 100;
percent = Math.round(percent);
console.log('Downloaded: ' + percent + '%');

store = cordova.file.externalRootDirectory;
// or
// store = "cdvfile://localhost/persistent/";
