Question

I am working the process of linking facebook login to my android application. In some tutorial I was asked to register my app with Facebook Developers website where I did everything but I couldnt find "Default Activity Class Name" in my Android Studio I have provided this below manifest file

    <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="in.evago.evago">

    <uses-permission android:name="android.permission.INTERNET" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <meta-data
            android:name="com.facebook.sdk.ApplicationId"
            android:value="@string/facebook_app_id" />

        <!-- Front Page -->
        <activity
            android:name=".Frontpage"
            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>

            <meta-data
                android:name="android.app.searchable"
                android:resource="@xml/searchable" />
        </activity>
        <!-- Search results activity -->


<activity
        android:name=".SearchResultsActivity"
        android:label="@string/title_activity_searchable"
        android:launchMode="singleTop"
        android:theme="@style/AppTheme.NoActionBar">
        <intent-filter>
            <action android:name="android.intent.action.SEARCH" />
        </intent-filter>
    </activity>
    <!-- Search results activity Ends -->

</application>

Please help me in locating the "Default Activity Class Name"

Answer 1

should be the class containing:

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

So its .Frontpage
