title: Memory Leak at Toast$TN.mNextView
body: <p>I add leak canary to my app and I find this memory leak: <a href="https://i.imgur.com/8nFOoH4.png" rel="noreferrer">https://i.imgur.com/8nFOoH4.png</a></p>
  
  <p>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?</p>
  
  <p>Here is my MainActivity xml:</p>
