What is a SplashScreen?

A splash screen is a screen that appears when you open an app on your mobile device. So, we can say that it is the first impression for the user. It is commonly used to show an application logo or an image associated with an application.

Implementation

So instead of using a layout file, we'll refer to the splash screen as the background of the activity theme. first, create an XML drawable splash_background.xml inside the res/drawable folder in

<?xml version="1.0" encoding="utf-8"?> 

   <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
   <item android:drawable="@color/white" />
   <item android:drawable="@drawable/ic_icon_vector" android:gravity="center" />

</layer-list>

next step, set splash_groundground.xml as the background for your splash activity in the theme. Add a new splash to your splash activity.

<!-- Splash Screen theme. -->
<style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">
<item name="android:windowBackground">@drawable/splash_background></item>
</style>

Add your theme to AndroidManifest.xml as your splash activity theme.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.exmple.splash">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/Theme">

        <activity
            android:name=".SplashActivity"
            android:theme="@style/SplashTheme">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest></pre><div>
}

Create a blank activity for SplashActivity.java without XML. This class will only redirect to MainActivity.java.

public class SplashActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        startActivity(new Intent(SplashActivity.this, MainActivity.class));
        finish();
    }
}

We have recently developed a site into the gatsby. Basically, the contact us feature is common on all websites. and we are implementing Mailchimp because it's a very popular platform in the email market. So, I will show you how to set up a Mailchimp on the Gatsby site.

Using gatsby-source-mailchimp

Use your Mailchimp API key to download your campaigns into Gatsby’s GraphQL data layer! Install the package by running the following command: npm i gatsby-source-mailchimp --save. How to configure Once the installation is complete, you can now add this plugin to your gatsby-config.js, like so: Configure Mailchimp Key and add this {resolve: gatsby-source-mailchimp} into the plugins array. code looks like,

module.exports = {
  // ...
  plugins: [
    {
      resolve: 'gatsby-source-mailchimp',
      options: {
        // Avoid including your key directly in your file.
        // Instead, opt for adding them to .env files for extra
        // security ;)
        key: 'asd712jdas90122jdas90122jkadsd1-usXX',
        rootURL: 'https://usXX.api.mailchimp.com/3.0',
      },
    },
  ],
  // ...
}

This plugin was made out of a specific necessity, so it doesn't cover all of Mailchimp’s data sources, focusing only on campaigns.

This plugin provides a few options. you can refer here

Using .env variables to hide your key

If you don’t want to attach your API key to the repo, you can easily store it in .env files by doing the following:

Put this in your .env file

MAILCHIMP_KEY = 'asd712jdas90122jdas90122jkadsd1-usXX';

Put this in your gatsby-config.js file

require('dotenv').config({
  path: `.env.${process.env.NODE_ENV}`,
});

module.exports = {
  // ...
  plugins: [
    {
      resolve: 'gatsby-source-mailchimp',
      options: {
        key: process.env.MAILCHIMP_KEY,
        rootURL: '[https://usXX.api.mailchimp.com/3.0',](https://usxx.api.mailchimp.com/3.0%27,)
        // ...
      },
    },
  ],
  // ...
};

We all know that recruitment becomes tough day by day as the competition is growing in the market. If I talk about the IT industry each Organisation is fighting hard to find candidates for various IT profiles. Now all IT HRs are in trouble with lots of targets of hiring and it’s not as easy as ABC in practical. Sometimes it takes a very long time to get a response from the market for a particular profile. Still, we need to pay attention to many things to make a smooth & effective recruitment process.

1. Build your network
2. Attractive & Innovative Job Posting
3. Choose Right Person & Be polite to others
4. Communication: Be a good listener
5. Affordability
6. Talent v/s Experience

1.Build your network:

“Network is net-worth”. Without a network, it is too difficult to reach the right one. Every HR needs to develop a professional network. If I talk about the IT field we need to develop a network on LinkedIn to reach maximum people. Send connection requests to them Talk with them and scan candidates over there. Not only this we can use Facebook as well as the young generation addicted to it and target the suitable person over there.

2. Attractive & Innovative Job posting:

We are living in a competitive era, where we are fighting hard to even get responses from the market side and that’s why we need to be creative & innovative while preparing Job descriptions. prepare star lines to attract people, use different ways to post the job, give information regarding facilities the company is providing, any other attraction if the company has.

3. Choose the Right Person & Be polite to others:

After receiving lots of CVs for a particular role, it’s too critical to scan all and invite a few for Interviews. After interviewing all people we need to think about the best suitable person for the job.

HR needs to develop a habit to wish all the best to the not selected candidate. It creates a positive image of the company in that person's mind. And yes the second thing is, never use the “REJECTED” word for any candidate just say ‘unfortunately you are not selected’, even you can say ‘sorry to say that you are not best fit for the job’. I am saying this because there is no rejection, only the thing is our requirement and the capabilities of the applicant are quite different.

4. Communication: Be a good listener:

Communication skill is essential for all HR Professionals. While interacting with candidates, be open, communicate each and everything. HR needs to communicate all the rules, regulations, policies, agreement terms & conditions (If you have), Training period, and the pay scale during training ( If you are hiring fresher), etc. After discussing all the required things with the candidate, if the candidate is found comfortable then only arrange his/her interview otherwise it will be a waste of time for both Employers as well as Employees.

While taking interviews not only ask questions and get answers, be a good listener. Listening to the candidate with patience may be a different way of presenting but one has really deep knowledge about the same and at least gives the chance to present.

5. Affordability:

Always keep in mind the budget of the company for a particular position and don’t waste your valuable time with overqualified people. Say NO to them with respect, you can say ‘we don't have any requirement regarding your profile’.

6. Talent v/s Experience:

While recruiting people never fixed the experience parameter as it may be possible that the less experienced person has more talent. Carefully analyze the person and then only select the best out of them.

I will discuss more tips on recruitment in my next blog….

Now create a card view in the main XML file. Here I used LinearLayout as the root widget, after using the card view. Below the codes that give you an idea of how to customize the card.
