If the app names are the same the reason can be using multiple launcher intent in your manifest file. Check your merged manifest file instead of application manifest file.

i think u must have used this intent filter twice in multiple activities.check your manifest file

Try to change capital letters to lowcase in your package name.

Why Custom Launcher doesn't work properly sometimes?

I created a custom launcher and set it to default launcher for my tablet. but when I open an application and then press Back button I will go to the last launcher(Default launcher of Samsung) although I setup my launcher as default before!
This is my launcher manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="launcher.base.app.ehsan.com.minelauncher">
<!-- To access internet -->
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<!-- To auto-complete the email text field in the login form with the JSON's emails -->
<uses-permission android:name="android.permission.GET_ACCOUNTS"/>
<uses-permission android:name="android.permission.READ_PROFILE"/>
<uses-permission android:name="android.permission.READ_CONTACTS"/>
<application

As you shared the link of application, there are only two permissions are needed
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
and You may need to add more permissions as per your requirements.
