如何在 Android 电视中保持屏幕开启

Question

I am developing two applications for android tv.

1. The first is a launcher to customize the startup interface a bit.

2. The second is a video player by HLS or Streaming by https.

They independently work great.

Then in the launcher I have an attempt that starts the video player after 1 minute. The problem is that after 20 minutes the Smart TV enters this suspension or low-power mode.

I already tried keepOnScreen in the layout, I tried WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON without good results.

Intent launchIntent = getPackageManager().getLaunchIntentForPackage("com.example.abc"); startActivity(launchIntent );

Note: When I open the multimedia application of the Smart TV and return to the player, the Smart TV does not turn off.

Answer 1

If you are using VideoSupportFragment then you can access to SurfaceView and do this in your onViewCreated(..) callback to keep the screen on:

getSurfaceView().setKeepScreenOn(true);

same in Kotlin:

surfaceView.keepScreenOn = true

---

OR, in your XML layout, add this to your View :

android:keepScreenOn="true"
