Too many Activities in Android?
android, android-activity, optimization
Solution
While creating complex applications you definite need to create many activities. So it depends on your application how many activities you need. No of activities in a project do not affect the performance.
The effect is produced by the number of activities in the stack of your android. So it is better to keep 5-6 activities in the stack(Finish activities if they are not needed any more).
So create as many Activities as your application demands but keep smaller no of Activities open at a time.
Problem
When i started my Android project i had a misunderstanding that every screen that's shown in the application must be a new activity. Now i am finished with the project , i have checked it on my emulator as well as on a couple of android phones. So far i am not witnessing any problems, but recently i read somewhere that too many activities in the application are a pretty bad idea. Currently my application has around 15-20 activities.Ideally i heard it should be around 5-6. Do i need to re-structure my code or just finishing every activity after it has done it's part is enough?
