Android create shortcuts on the home screen

AndroidMobile DevelopmentApps/Applications

This example demonstrates about Uninstall APKs programmatically

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.xml.

<?xml version = "1.0" encoding = "utf-8"?>
<LinearLayout xmlns:android = "http://schemas.android.com/apk/res/android"
   android:orientation = "vertical"
   android:layout_width = "match_parent"
   android:gravity = "center"
   android:layout_height = "match_parent">
   <TextView
      android:id = "@+id/text"
      android:layout_width = "fill_parent"
      android:gravity = "center"
      android:textSize = "30sp"
      android:layout_height = "wrap_content"
      android:text = "Click here"/>
</LinearLayout>

In the above code, we have taken a text view.

Step 3 − Add the following code to src/MainActivity.java

package com.example.myapplication;
import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.net.Uri;
import android.os.Bundle;
import android.support.v4.content.pm.ShortcutInfoCompat;
import android.support.v4.content.pm.ShortcutManagerCompat;
import android.support.v4.graphics.drawable.IconCompat;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends Activity {
   private static final String PREF_KEY_SHORTCUT_ADDED = "Sairam";
   TextView text;
   @Override
   public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      text = findViewById(R.id.text);
      text.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            if (ShortcutManagerCompat.isRequestPinShortcutSupported(getApplicationContext())) {
               ShortcutInfoCompat shortcutInfo = new ShortcutInfoCompat.Builder(getApplicationContext(), "#1")
                  .setIntent(new Intent(getApplicationContext(), MainActivity.class).setAction(Intent.ACTION_MAIN)) // !!! intent's action must be set on oreo
                  .setShortLabel("Test")
                  .setIcon(IconCompat.createWithResource(getApplicationContext(), R.drawable.logo))
                  .build();
               ShortcutManagerCompat.requestPinShortcut(getApplicationContext(), shortcutInfo, null);
            } else {
               Toast.makeText(MainActivity.this,"launcher does not support short cut icon",Toast.LENGTH_LONG).show();
            }
         }
      });
   }
}

Step 4 − Add the following code to Manifest.xml

<?xml version = "1.0" encoding = "utf-8"?>
<manifest xmlns:android = "http://schemas.android.com/apk/res/android"
   package = "com.example.myapplication">
   <uses-permission android:name = "android.permission.INTERNET" />
   <uses-permission android:name = "com.android.launcher.permission.INSTALL_SHORTCUT" />
   <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/AppTheme">
      <activity
         android:name = ".MainActivity"
         android:configChanges = "keyboardHidden|orientation|screenSize">
         <intent-filter>
            <action android:name = "android.intent.action.MAIN" />
            <action android:name = "android.intent.action.CREATE_SHORTCUT" />
            <category android:name = "android.intent.category.LAUNCHER" />
         </intent-filter>
      </activity>
   </application>
</manifest>

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from an android studio, open one of your project's activity files and click Run  icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen –

Now click on home button, it will show the result as follows
