Android: Translucent status bar not working with Google Maps API

I have found the solution. Set android:fitsSystemWindows in DrawerLayout to "false", if anyone is adding a map to drawer layout.

If you add your map in an Activity, then write these lines of code in your onCreate() method:

    window.apply {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
            addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
            decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                statusBarColor = Color.TRANSPARENT
        }
    }

If you add maps in a Fragment, then add these lines of code in onCreate() method:

    activity!!.window.apply {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
            addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
            decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                statusBarColor = Color.TRANSPARENT
        }
    }
