我最近将支持设计库更新到最新版本，现在每个具有 CollapsingToolbarLayout 的 Activity 都会引发以下异常:

    java.lang.NoSuchMethodError: No static method setLayoutDirection(Landroid/graphics/drawable/Drawable;I)V in class Landroid/support/v4/graphics/drawable/DrawableCompat; or its super classes (declaration of 'android.support.v4.graphics.drawable.DrawableCompat' appears in /data/data/com.radioafrica.music/files/instant-run/dex/slice-com.android.support-support-v4-24.0.0-beta1_f8cf3ba4c70f87f407a745b9fa14a2205d0b587c-classes.dex)
