Android TV not starting LAUNCH_LEANBACK Activity

Question

I want to create a single apk that will be compatible with mobile and TV. As I understand I should specify the launcher activity for both platforms in manifest, one for mobile with <category android:name="android.intent.category.LAUNCHER" />, another for TV with <category android:name="android.intent.category.LEANBACK_LAUNCHER" /> intent filter. And Android should automatically pick the right activity when launching, depending on platform, right ? Or I should add some java code and start my TV activity from code ? Currently it launch my mobile activity when using android TV emulator. Below is my manifest file :

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

    android:versionName="2.0.142" >

    <uses-sdk tools:overrideLibrary="android.support.v17.leanback"/>

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

    <uses-feature
        android:name="android.hardware.microphone"
        android:required="false" />

    <uses-feature
        android:name="android.hardware.bluetooth"
        android:required="false" />

    <!-- TV -->
    <uses-feature
        android:name="android.hardware.touchscreen"
        android:required="false" />

    <uses-feature android:name="android.software.leanback"

            </intent-filter>
        </activity>
 .... other activities
    </application>

</manifest>

SOLVED

My mobile activity was specified explicitly in Run configurations as launcher. After I set Launch default Activity everything works fine.
