android toast内存泄漏,android - Memory Leak at Toast$TN.mNextView - Stack Overflow

I add leak canary to my app and I find this memory leak: https://i.imgur.com/8nFOoH4.png

I don't use at my MainActivity LinearLayout or Toast but I has this leak and I can't understand why and how. Maybe it because I use toasts and linear layout inside fragments that I use in MainActivity?

Here is my MainActivity xml:
