How to open main activity from two separate icons with different ui

I have an app that the main activity is including a map. I want to create two icons on my home screen launcher, both of them will open the same main activity but with a different UI on the map.

For example : If I will press on icon A the app will be open with a fab on the map, and if I will press on icon B the app will be open without the fab on the map.

First you need to add second launcher intent to your manifest. 

        <activity
        android:name=".yourpackage.MapActivity"
        android:launchMode="singleTask"
        android:screenOrientation="portrait">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>
            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>

        <meta-data android:name="visibility" android:value="0"/>
    </activity>

    <activity-alias
        android:name=".MapWithoutFabActivity"
        android:targetActivity=".yourpackage.MapActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>
            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>

      <meta-data android:name="visibility" android:value="1"/>
    </activity-alias>

Next we need modify our map MapActivity for being ready to change visibility of fab button.

public class MapActivity extends AppCompatActivity {

   protected int fabVisibility = View.VISIBLE;

   @Override protected void onCreate(@Nullable Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);

       // Hope this method works. 
       Bundle bundle = getPackageManager().getApplicationInfo(getPackageName(), PackageManager.GET_META_DATA).metaData;
    int visibility = Integer.valueOf(bundle.getString("visibility"));
    fab.setVisibility(visibility);
   }

protected void onNewIntent(Intent intent) {
       Bundle bundle = getPackageManager().getApplicationInfo(getPackageName(), 
       PackageManager.GET_META_DATA).metaData;
       int visibility = Integer.valueOf(bundle.getString("visibility"));
       fab.setVisibility(visibility);
}

Good luck there
