Tested with Leak Canary
Android OS starts activities up to intents you send as a broadcast, but because it is done privately, you cannot track those activities. You may never know which activity is currently visible, unless you work around somehow. This library will provide you to manage that.
This library uses a singleton class to create a static object and keep instances of your activities. So, you can reach them out whenever you want, and do whatever you wish.
To use this library, you need to notify TheActivityManager
onDestroy of activity.
You can call these methods by yourself in every activity that you create
To simplify this step i created a
TAMBaseActiviy, which extends from AppCompatActivity, so just extend your activities from this and it will take care of the rest.
if your application's minSdkVersion >= 14 then you can simply call
TheActivityManager.getInstance().configure(application) and it will handle all.
CAUTION: If you call configure method, you MUST call it only once, and you MUST NOT extend your activities from
TAMBaseActiviy otherwise it will create multiple instance in TheActivityManager array, which may cause crash!
- This method basically return the instance of current activity and you can use it to compare with something or display dialog, popup or whatever you wish, you can call any method on that activity now. This will provide you to access almost every activity.
- You can check whether application is currently running or it's been paused for some reason. For instance, you have a service to download something and when it is completed you can just check whether user is still using the application or not, you can have different ways to go.
- It doesn't matter how deeply you are in the application, this method will finish all of activities and will quit application.
- It doesn't matter how deeply you were visiting detail pages on application, this method will turn you back to landing page which you should set first by calling `setAsLanding` method otherwise it will just act like `finishAll` method.
- Let's assume that you have Activity A and C but before you go to C you need to do something in Activity B. So you tell TheActivityManager that C is your nextStep with the extras if necessary and when you done with B just call moveForward method and TheActivityManager will lead user to that acitivity with already given extras.
Add library dependency to your
I thought to name it as ActivityManager but didn't want it to be confused with Android's ActivityManager and than my friend remind me John Carmack's tweet and it was just perfect fit, so it became "TheActivityManager".

I have moved to naming global singletons with a The* prefix -- ThePacketServer, TheMasterServer, TheVoip, etc. Feels pretty good.— John Carmack (@ID_AA_Carmack) 11 Mart 2015
This library works on 2.2+ probably earlier as well, but i didn't even bother to test because i believe at some point we have to stop supporting every version ;)
