android - Why does SeekBar customization work on 4.1 but not on 4.2 and 4.3? -

i've created custom seekbar , works perfect 4.1 devices, on 4.2 , 4.3 devices not show background, leaves blank.

this do:

myseekbar.setprogressdrawable(getresources().getdrawable(r.drawable.seekbar_progress)); myseekbar.setbackgrounddrawable(getresources().getdrawable(r.drawable.slider_shape)); 

seekbar_progress.xml:

<layer-list  xmlns:android="http://schemas.android.com/apk/res/android"> <item      android:id="@android:id/background">         <bitmap              android:src="@drawable/slider_background_part"             android:tilemode="repeat">         </bitmap> </item> <item      android:id="@android:id/progress">     <layer-list          xmlns:android="http://schemas.android.com/apk/res/android" >         <item>             <clip>                <color                    xmlns:android="http://schemas.android.com/apk/res/android"                    android:color="@color/my_slider_color"/>             </clip>         </item>         <item>             <clip >                 <bitmap                      xmlns:android="http://schemas.android.com/apk/res/android"                     android:src="@drawable/slider_foreground_part"                     android:tilemode="repeat"/>             </clip>         </item>     </layer-list> </item> 

in file i'm repeating image progress , background, , progress, give color. still need set shape background. if don't this, background remains blank.

slider_shape.xml:

<shape      xmlns:android="http://schemas.android.com/apk/res/android">     <corners android:radius="0dp"/> </shape> 

can me here?
