my modified as follows:
3 . use of Android Studio Profiler export the original file hprof
4 using android sdk comes. hprof-conv tool in platform-tools hprof converting the original document, the following command:

Step 4: Select and right -> List objects -> with incoming references cited examples of open view.
Step 5: In view of the reference example, continue to select and right -> Path To GC Roots -> with all references to see all references to the path.
