How can I add my application's shortcut to the homescreen upon app installation? [duplicate]

Answer 1

1. Create function to call intent of shortcut:

   private void criarAtalho() {
       Intent shortcutIntent = new Intent(getApplicationContext(), SplashScreen.class);
       shortcutIntent.setAction(Intent.ACTION_MAIN);
       Intent addIntent = new Intent();
       addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
       addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, "nomeDaApp");
       addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, Intent.ShortcutIconResource.fromContext(getApplicationContext(), R.mipmap.ic_launcher));
   
       addIntent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
       addIntent.putExtra("duplicate", false);  //may it's already there so don't duplicate
       getApplicationContext().sendBroadcast(addIntent);
   }
   

2. write on OnCreat the call of function:

   if(!getSharedPreferences("APP_PREFERENCE", Activity.MODE_PRIVATE).getBoolean("IS_ICON_CREATED", false)){
       criarAtalho();
       getSharedPreferences("APP_PREFERENCE", Activity.MODE_PRIVATE).edit().putBoolean("IS_ICON_CREATED", true).commit();
   }
   

3. set the permissions on manifest:
