Answer 1

If you dont want your "Translucent navigation" transparent, here is the code to just make transparent the status bar

In your theme:

    <item name="android:statusBarColor">@android:color/transparent</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowTranslucentStatus">true</item>

In your activity onCreate:

Window window = getWindow();
WindowManager.LayoutParams winParams = window.getAttributes();
winParams.flags &= ~WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;
window.setAttributes(winParams);
window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);

In Kotlin just use following code in your activity, also add android:fitsSystemWindows="true" in your parent view of activity.xml layout file. This will also show content over navigation bar too, provided you declared full screen style in your style.xml

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
     window.setFlags(
            WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
            WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS
        )
    }
