android-tv

I've installed the androidtv-sample-inputs so I can fake some Tv inputs and have some channels and I wanted to get information about that channels, however, when I query to get that information I get an empty cursors. What i've tried so far is: TvInputManager tv = (TvInputManager)getApplicationContext().getSystemService(Context.TV_INPUT_SERVICE); List<TvInputInfo> list = tv.getTvInputList(); String[] projection = { TvContract.Channels._ID, TvContract.Channels.COLUMN_DISPLAY_NUMBER }; ContentResolver cr = getContentResolver(); Iterator<TvInputInfo> it = list.iterator(); while(it.hasNext()) {

I use the leanback library to develop for Android TV. My app declare the min API to 16 however the leanback as a minimum API of 16. So as the documentation says I declared this in my manifest : <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" package="com.mypackage.package"> <uses-sdk tools:overrideLibrary="android.support.v17.leanback" /> However I still have the error : Error:(6, 5) Execution failed for task ':app:processAdhocProdManifest'.

In order to define different dimension values for 1080p and 720p android TV, I need to decide which qualifier I should use. When I'm trying to use something like values-sw1080p,values-sw720p, it doesn't work. The values in dimes.xml doesn't affect anything. But it works if I'm using qualifier like -sw540dp,-sw360dp. I don't really understand why like that. Any idea? Thanks. First of all, you are substantially correct. You can use sw360dp/ : 720p screens sw540dp/ : 1080p screens The reason why sw720p/sw1080p don't work is because they don't exist as qualifiers. This is the official

I'm trying to make an horizontal list with a RecyclerView , that when I put the focus on an item, increase the size of this. I want to make this effect: Do you have any ideas to accomplish this?
