Android Deep Linking Example

In this tutorial you will learn about android deep linking with an example.

In deep linking first we have to understand what does an URI means. Let us consider an example of URI,

https://www.example.com/demo?userid=100&client=android

Here,

  • https is a scheme
  • www.example.com is a host
  • /demo is a path, directing the specific resource
  • ?userid=100&client=android is a query string with key-value pairs like the hashmap in java.

Deeplink is defined as a source of content to content web to your android application and in deeplink whenever user opens an URI and if that URI is deep link with any application then it opens a dialog prompt that open with that app or open with browser only.

We can create deeplink over network that is connecting website directly to the application or we can create custom deplink also like myApplication://….

Android Deep Linking Example

First of all create a new android project to understand deeplink in android app.

Now make intent filter in the activity that you want to open when user click on weblink.

<intent-filter android:label="@string/app_name">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="myapp"
android:host="myhost"
android:pathPrefix="/help"/>
</intent-filter>

What we are doing in this project is when we are clicking on weblink then we are opening the app and showing the weblink in the text view.

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:textSize="20sp"
        android:id="@+id/deepLinkText"
        android:textColor="#000000"/>

</RelativeLayout>

Now we are designing its java class to represent weblink when user click on it on textview.

MainActivity.java

package com.example.deeplinkdemo;

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Intent intent=getIntent();

        if(intent!=null&&intent.getData()!=null){
            ((TextView)findViewById(R.id.deepLinkText)).setText(intent.getData().toString());
        }
    }
}

Build app for about project and install it in your mobile device.

Below we are designing a custom html file when user open that html file and click on the link on that html file then our app will open.

<!DOCTYPE html>
<html>
<head>

<body>

        <a href="myapp://myhost/help">myapp://myhost/help</a>

</body>

</head>

</html>

Now you can run and test your application.

Rail Fence Cipher Program in C and C++[Encryption & Decryption]

Here you will get rail fence cipher program in C and C++ for encryption and decryption. It is a kind of transposition cipher which is also known as zigzag cipher. Below is an example. Here Key = 3. For encryption we write the message diagonally in zigzag form in a matrix having total rows = key and total columns = message length. Then read the matrix row wise horizontally to get encrypted message. Rail Fence Cipher Program in C #include<stdio.h> #include<string.h> void encryptMsg(char msg[], int key){ int msgLen = strlen(msg), i, j, k = -1, row = 0, col = 0; char railMatrix[key][msgLen]; for(i = 0; i < key; ++i) for(j = 0; j < msgLen; ++j) railMatrix[i][j] = '\n'; for(i = 0; i < msgLen; ++i){ railMatrix[row][col++] = msg[i]; if(row == 0 || row == key-1) k= k * (-1); row = row + k; } printf("\nEncrypted Message: "); for(i = 0; i < key; ++i) f...

Data Encryption Standard (DES) Algorithm

Data Encryption Standard is a symmetric-key algorithm for the encrypting the data. It comes under block cipher algorithm which follows Feistel structure. Here is the block diagram of Data Encryption Standard. Fig1: DES Algorithm Block Diagram [Image Source: Cryptography and Network Security Principles and Practices 4 th Ed by William Stallings] Explanation for above diagram: Each character of plain text converted into binary format. Every time we take 64 bits from that and give as input to DES algorithm, then it processed through 16 rounds and then converted to cipher text. Initial Permutation: 64 bit plain text goes under initial permutation and then given to round 1. Since initial permutation step receiving 64 bits, it contains an 1×64 matrix which contains numbers from 1 to 64 but in shuffled order. After that, we arrange our original 64 bit text in the order mentioned in that matrix. [You can see the matrix in below code] After initial permutation, 64 bit text passed throug...

Experimental: Reducing the size of .NET Core applications with Mono's Linker

The .NET team has built a linker to reduce the size of .NET Core applications. It is built on top of the excellent and battle-tested mono linker . The Xamarin tools also use this linker so it makes sense to try it out and perhaps use it everywhere! "In trivial cases, the linker can reduce the size of applications by 50%. The size wins may be more favorable or more moderate for larger applications. The linker removes code in your application and dependent libraries that are not reached by any code paths. It is effectively an application-specific dead code analysis ." - Using the .NET IL Linker I recently updated a 15 year old .NET 1.1 application to cross-platform .NET Core 2.0 so I thought I'd try this experimental linker on it and see the results. The linker is a tool one can use to only ship the minimal possible IL code and metadata that a set of programs might require to run as opposed to the full libraries. It is used by the various Xamarin products to extract...
