java.lang.NullPointerException: Attempt to read from field 'java.lang.Object com.facebook.stetho.inspector.elements.ElementInfo.parentElement' on a null object reference
I used the stetto (http://facebook.github.io/stetho/) for the network and database inspector for my android app.My app takes the following steps. Open Activity and Fragment -> Open DialogFragment + send request -> Open nested DialogFragment(into childFragmentManager) -> Close nested DialogFragment -> Close DialogFragment(back to Activity) and i get an error message. I'm trying to figure out why this doesn't work, but I don't know why one of the children of ElementInfo is null. And I see the same problem in the past, sorry if there is a solution, but I cannot find it.
