Android app is creating duplicated shortcut in homescreen -

i run app on emulator (and on phones) , creating 2 shortcuts in homescreen. if delete app, removes both shortcuts.

my app have on splash screen go main screen , i'm using android studio.

i believe related <intent-filter> each time delete when run app appears again automatic on both <activity>.

manifest file:

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"     package="com.example.epicbit.tecnoprolab"     android:versioncode="1"     android:versionname="1.0" >      <uses-sdk         android:minsdkversion="15"         android:targetsdkversion="23" />      <receiver android:name="receiver.networkchangereceiver" >         <intent-filter>             <action android:name="android.net.conn.connectivity_change" />         </intent-filter>     </receiver>      <uses-permission android:name="android.permission.internet" />     <uses-permission android:name="android.permission.access_network_state" />     <uses-permission android:name="android.permission.change_network_state" />      <application         android:allowbackup="true"         android:hardwareaccelerated="true"         android:icon="@mipmap/ic_launcher"         android:label="@string/app_name"         android:supportsrtl="true"         android:theme="@style/apptheme" >          <!-- splash screen -->         <activity             android:name="com.example.epicbit.tecnoprolab.splashscreen"             android:label="@string/app_name"             android:theme="@android:style/theme.black.notitlebar" >             <intent-filter>                 <action android:name="android.intent.action.main" />                  <category android:name="android.intent.category.launcher" />             </intent-filter>         </activity>         <activity             android:name="com.example.epicbit.tecnoprolab.mainactivity"             android:label="@string/app_name"             android:theme="@style/apptheme.noactionbar" >             <intent-filter>                 <action android:name="android.intent.action.main" />                  <category android:name="android.intent.category.launcher" />             </intent-filter>         </activity>     </application> 

edit: check video understand happen when follow sugestions:

remove code below mainactivity

<intent-filter>     <action android:name="android.intent.action.main" />      <category android:name="android.intent.category.launcher" /> </intent-filter> 

your splashscreen root activity of app... so, parameters needed splashscreen.

final result

<!-- splash screen --> <activity     android:name="com.example.epicbit.tecnoprolab.splashscreen"     android:label="@string/app_name"     android:theme="@android:style/theme.black.notitlebar" >     <intent-filter>         <action android:name="android.intent.action.main" />          <category android:name="android.intent.category.launcher" />     </intent-filter> </activity> <activity     android:name="com.example.epicbit.tecnoprolab.mainactivity"     android:label="@string/app_name"     android:theme="@style/apptheme.noactionbar" > </activity> 

update

i checked picture.

i saw updating following file:

app/build/intermediates/manifests/full/debug/androidmanifest.xml 

however, app/build file folder android studio put generated files...

try search manifest in source code folder.. like:

app/src/... (or other folder different build)
