How to disable status bar - Android

[IamDK]

I have a Keyboard+Mouse connected to my Android tablet running SteamLink.

The mouse cursor works fine for the most part but I have two minor issues. (I am using Diablo2 as my steam link game).


1) If I move the mouse too far up, the android status/notification bar gets summoned on top of the stream, and this interrupts the game input.

When the mouse moves too far up, the android cursor (which was previously hidden while streaming) appears on the summoning status/notification bar, interrupting the input.


2) Right click does not get forwarded to game/windows client.

Perhaps issue #2 is a VERY easy fix.

The right button mouse click in Android typically invokes BACK.
Steamlink successfully ignores the BACK action, but it does not invoke the right click action.
(Middle Mouse click and Left Click both work as expected).

I found a hacky solution for issu #2.
My tablet is rooted and I used TinCore KeyMapper to remap the right mouse button click into a keyboard input.

Perhaps issue #1 may not be fixable without an Android OS update.

The action of summoning the status bar is a deeper action invoked by com.android.systemui, which is not modifiable.

Does android potentially support "cursor lock" functionality, which may be able to keep the cursor centered instead of allowing it to travel upwards?

In the mean time, I found a hacky solution for fix issue #1 for rooted devices.

Enabling the following via ADB:

su settings put secure user_setup_complete 0

on my setup causes the top status bar NOT appear when the mouse is dragged to the top screen position.

I am still on Android7, but will retest when I get an Android8 device or update.

Android 8.0 and later support cursor focus capture, which Steam Link supports. If you're on Android 7.x or earlier, though, there's no cursor focus capture, and so the cursor will potentially summon the status bar if you move up that high.
