java - singleton class that survives Process termination

Question

I've read several post regarding singleton class destruction or singleton pattern is bad in android like this and this

But I am not able to understand how to declare a singleton class properly or use sharedpreference for persistance can anyone provide any example on how to maintain global objects across application or how to achieve this in proper way any help is appreciated.

Answer 1

I think this link you mentioned is quite good.As my personal experience the best way to maintain global objects in an application is to use a class that extends from Application class, then you can manage objects by setter and getter methods in that class.This technically works like a Singleton in android except most of house keeping is done by android so it's very wise to use this mechanism instead of singleton. On the other hand shared preferences has entirely different job and used for mainly storing some user data and behavior
