App crash on API 16 Phone when add drawable background on LinearLayout

Issue

When adding a drawable frame background in LinearLayout, the APP will crash on API 16 19 (Tested) but works on API 21 27. The LineayLayout is an item view in recyclerView and there is no animation for this background, it should work for all API level

        <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorGreen</item>
    <item name="colorPrimaryDark">@color/colorGreen</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

Layout:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="@dimen/margin_small"
android:background="@drawable/bg_frame_rounded_transparent_strokegreens"
android:orientation="vertical">

bg_frame_rounded_transparent_strokegreens:

Solution

You've used ?attr/colorPrimary as your colour but this is only available on older APIs if you are using an AppCompat theme. Check your theme has a parent that is from AppCompat.
