How to get which activity is running android studio

I`m trying to check the flow of my program and to do so I need a way to get the type of a class that is currently running.

I tried searching the web for some info about the subject but as I see most of the examples add a static variable for the active data.

Beside testing the logic of my program I want to test the GUI as well so I will be able to check that after I press a button the correct activity is running.

There isn't much info about testing on Android studio so any help will be highly appreciated (Such as "You are in a completely wrong path, you can test your GUI by...")

Thanks

You can use Application.ActivityLifecycleCallbacks interface for this approach.

First step is implement Application.ActivityLifecycleCallbacks to your Application class.

class MyApplication extends Application implements Application.ActivityLifecycleCallbacks {...}

Second step is just register for Application.ActivityLifecycleCallbacks callbacks in your MyApplication.class's onCreate method

 @Override
    public void onCreate() {
        super.onCreate();
        registerActivityLifecycleCallbacks(this);
    }

Last step is just override the methods from Application.ActivityLifecycleCallbacks in MyApplication class

void onActivityCreated(Activity var1, Bundle var2);

void onActivityStarted(Activity var1);

void onActivityResumed(Activity var1);

void onActivityPaused(Activity var1);

void onActivityStopped(Activity var1);

void onActivitySaveInstanceState(Activity var1, Bundle var2);

void onActivityDestroyed(Activity var1);

Now you can easily know which activity is currently running :) Happy coding!
