Does the number of cases in the Android app matter?

I am developing an Android application. I have already overcome more than 20 activities. Therefore, I am a little concerned about this. I mean, if there are more actions in an Android application, does this affect the performance of the application, for example Speed, Memory, or any other problem?

Although this is not a standard question, but still I feel it is something that can help others too

Yes Suraj more actions will affect performance.
Action is equivalent to Frame / Window in GUI sets. It occupies the entire available area of ​​the screen (minus the status header and title bar). Actions are intended to display the user interface and receive input from the user. Activity (call-Activity) can generate another action (sub-activity) in two ways:

  • Fire and forget - create an event (intention) and start it
  • Async callback - create an event (Intent), fire it, and wait for its response in the callback (caller-action) method.
