Integrate SQLite plugin in PhoneGap iOS application

For offline storage in PhoneGap application, we can use local storage or storage API. But there are some limitations of this storage mechanism. So here we will discuss on creating local database with larger storage limits with the help of SQLite plugin.

Few tips on JavaScript – Part I

var myArray=["test","xyz","great"];
console.log("MyArray Length (Without Quotes)="+myArray.length);
console.log("MyArray Length (With Quotes)="+myArray["length"]);

MyArray Length (Without Quotes)=3
MyArray Length (With Quotes)=3

As we know that we can access Array properties by array name with dot notation. But we also can access the array properties through the array square bracket within the quote. The array operator (square brackets) is also used for accessing the array’s properties (arrays are also objects in JavaScript) .So we can access the array length property within the quotes in the array square bracket.

Data passing in multiple screens from one activity to another using Xamarin in Android

Introduction :-
In this Article, we will see how to create multiple screens in Android using Xamarin and pass data between them.

Intents are the classes that describe a message, both what the desired action of the message is and a data payload to send along with it. They are commonly used within applications to launch Activities. To launch a new Activity, we create a new Intent, set the Context and the Activity class to launch and then tell the OS to handle the Intent, which launches the Activity. Continue reading
