Android SeekBar's progressBackgroundTint has no effect in API v21

Question

I'm noticing that when changing my SeekBar's progressBackgroundTint attribute, it gets completely ignored and has no effect. It doesn't matter what color I set it to; it always shows as gray on my device. Is this a bug with Android, or am I doing something wrong? When I switch the preview in Android Studio to v22, it gets properly set. But not so on v21.

My seekbar:

<SeekBar
    android:layout_width="300dp"
    android:layout_height="wrap_content"
    android:id="@+id/seekBar"
    android:max="100"
    android:progress="50"
    android:progressBackgroundTint="#ff4babe8"/>

I also tried setting progressBackgroundTintMode to all the known values, but still no effect. Anyone know why?

Your hex color has 2 too many characters... 8 instead of 6. – Exultant

@MikePurcell: The first hex byte (FF) is the alpha value. See e.g. android.graphics.Color. So problem is not there. – Disappoint

May be it only work for device with OS lollipop or greater – Expend

try using android:progressTint along with android:progressBackgroundTint

<ProgressBar
     android:progress="100"
     android:progressBackgroundTint="@color/buttonPrimary"
     android:progressTint="@color/buttonPrimary"
     android:id="@+id/progressBar"
     style="?android:attr/progressBarStyleHorizontal"
     android:layout_width="match_parent"
     android:layout_height="wrap_content" />

I just discovered this issue and then found out that the material components provide a Slider that works pretty much the same way and doesn't have this issue. Check out details here https://developer.android.com/reference/com/google/android/material/slider/Slider
