So we get the appropriate folder to put your resources in.ĮDIT: on that same page, it is stated that there is a specific tvdpi qualifier that you can use for your TV-related resources (around 213 dpi). Let's assume we have a 1080p display with an extra high density dpi). Of course, a TV can have different densities: this table tells you more about it (source: official documentation). While in this case we have: dp = px * 160 / dpi The formula is pretty simple: px = dp * (dpi / 160) As you can read, there are two different units to take into account if you want to calculate your dp folder: the pixel count (e.g., 720) and the pixel density (that is, the dot-per-inch unit, or how many pixels fit into a single inch). This is the official documentation about working with different screen sizes. The reason why sw720p/sw1080p don't work is because they don't exist as qualifiers.

The documentation is sparse and slightly contradictory, but I base this primarily on these sources:įirst of all, you are substantially correct. (Note in particular that the -tvdpi qualifier is specific to 720p, and is almost certainly not what you want to use to support modern TVs.) Similarly, dimensions/layouts intended to only target 4k TVs could be placed in -xxxhdpi. If (optional) high-resolution versions of images are desired for 4k TVs, they can be supplied as “2x” images, and stored in a drawable-xxxhdpi folder. The “standard” images and layouts for TV could be stored in a -xhdpi folder, as xhdpi is the qualifier used for 1080p TVs. If you need to deliver different images and layouts for the different TV sizes, though, you can use the screen density qualifiers above. This implies that, if you follow this advice and always design to a 1080p specs, you could use the -television UI Mode Qualifier and be done with it. Then allow the Android system to downscale your layout elements to Your TV layout should target a screen size of 1920 x 1080 pixels, and Once you set the box video output to 1080p and click on info button, you should see the resolution for that station listed as 1920x1080 at 60p. For example, xfinity set our boxes to default 720p. 1080p (1920×1080 progressively displayed pixels also known as Full HD or FHD, and BT.709) is a set of HDTV high-definition video modes. The full-color image shows 1080 resolution. The blue-tinted image shows 720p resolution, an HDTV level of resolution.

xxxhdpi - (640dpi) - intended for 4k (Ultra HD) televisions. The cable box usually has a setting to change the viewing resolution. The red-tinted image shows 576i or 576p resolution.

xhdpi - (320dpi) - intended for 1080p (HD) televisions.

tvdpi - (213dpi) - intended for 720p televisions.

There are three screen densities that can be considered for Android TV, and three corresponding qualifiers.
