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?

Answer: 
Try this library. 
It works great simple
<https://github.com/ahmedrizwan/SeekBarCompat>
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" />

```
