Add below code to your manifest file :

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

        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
    <intent-filter>
        <action android:name="com.google.zxing.client.android.SCAN" />

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

And the fllowing permissions

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