android.widget.FrameLayout.layoutChildren

I am Currently getting tons of crashes in Fabric regarding many different instances of the same crash. I.E FrameLayout.java line 275, FrameLayout.java line 405, FrameLayout.java line 531. There is no clear indication as to what is happening when this crash happens. There is especially no line reference to any of my code. Has anyone experienced anything like this, does anyone know what is causing this, and does anyone know a solution to the problem? Thank you!

    **FrameLayout.java line 531
    android.widget.FrameLayout.layoutChildren**
