Error inflating class android.su

同样的程序，放在两台安卓机上运行，一台正常，一台直接闪退，郁闷...
查看报错信息：android.view.InflateException: Binary XML file line #124: Binary XML file line #124: Error inflating class android.support.design.widget.FloatingActionButton 指向了布局文件里的FloatingActionButton控件。经过排查，发现错误在于：

android:backgroundTint="@color/yellow"

应改为：

app:backgroundTint="@color/yellow"
