if your Activity class not directly inside the src folder means you have to mention package name in manifest file .i think you missed package name of welcome class

activity structure like this format

   android:name=".packagename.package2..upto..packageN.className"

so change

 <activity
      android:name=".packagename.Welcome">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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