Android Manifest Launcher Not Found

问题

I changed my Launcher activity to a different activity than the default Activity. But when I am running the Application I am not able to start the application. In the logCat it is saying that the application has been installed but I am not able to see the app in the home screen.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.collegehack"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="14"
    android:targetSdkVersion="21" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".Days"
        android:label="@string/app_name" 
        android:theme="@android:style/Theme.Holo" >
        <intent-filter>
            <action android:name="android.intent.action.DAYS" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:theme="@android:style/Theme.Holo" >
        <intent-filter>
            <action android:name="com.example.collegehack.MAIN" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

</application>

</manifest>

Please tell me where I am going wrong. Thanks in advance.

Remove intent filter of Main Activity and put this intent filter to your Days Activity:

<intent-filter>
       <action android:name="android.intent.action.MAIN" />
       <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

Try adding this to your AndroidMainfest.xml file

 <activity
     android:name=".YourActivityName"> //activty name which you want to launch first
            <intent-filter>//this intent code helps you launch activity when the app starts
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
