5. Navigation • D-Pad in two axis • enter Button • Back • Home
7. Navigation support • use appropriate states for better recognotion of focus/ selection • use sound - occasionally • use next focus targets - for defining own navigation flow ⇒ TEST IT properly
8. how to get started • Sample Project https://github.com/googlesamples/androidtv- Leanback/ • DevByte Video https://www.youtube.com/watch? v=72K1VhjoL98
9. needed libraries • v17 leanback support library • v7 recyclerview support library • v7 cardview support library forces to use also • v4 support library
10. AndroidManifest extension <activity android:name="MainActivity" android:label="@string/app_name" android:theme="@style/Theme.Leanback"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LEANBACK_LAUNCHER" /> </intent-filter> </activity>
11. AndroidManifest extension <activity android:name="MainActivity" android:label="@string/app_name" android:theme="@style/Theme.Leanback"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LEANBACK_LAUNCHER" /> </intent-filter> </activity>
12. AndroidManifest extension <activity android:name="MainActivity" android:label="@string/app_name" android:theme="@style/Theme.Leanback"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LEANBACK_LAUNCHER" /> </intent-filter> </activity>
13. Not supported Hardware features • android.hardware.touchscreen • android.hardware.telephony • android.hardware.camera • android.hardware.nfc • android.hardware.location.gps • android.hardware.microphone
14. avoid filtering in play store • set the attribute “required” to “false” in AndroidManifest ⇒ If you don’t to this, the application cannot be found on the play store for TV
15. recognize TV programmatically UiModeManager uiModeManager = (UiModeManager) getSystemService(UI_MODE_SERVICE); if (uiModeManager.getCurrentModeType() == Configuration.UI_MODE_TYPE_TELEVISION) { Log.d(TAG, "Running on a TV Device") } else { Log.d(TAG, "Running on a non-TV Device") }
