A memory leak occurs when the screen rotates

[taka-me]

If we do not use the Dialog Fragment or showDialog method, it seems that the dialog does not regenerate when the screen rotates, causing a memory leak.

Do you have a proof of the memory leak? Because I don't find any code that could lead to memory leak in https://github.com/hotchemi/Android-Rate/blob/master/library/src/main/java/hotchemi/android/rate/AppRate.java and https://github.com/hotchemi/Android-Rate/blob/master/library/src/main/java/hotchemi/android/rate/DialogManager.java

@taka-me @haijima Fixed in https://github.com/Vorlonsoft/AndroidRate (Release 1.1.6+). Could you check it and confirm it? Fix was in AppRate.java:
private static AppRate singleton;
changed to
private static volatile AppRate singleton = null;
