I am developing an android application using java. In which i am facing a problem that some of my activities are taking too much time to load approximately 3 to 4 second after click. There is one thing that i would like to mention here in order to explain the problem clearly and to get the exact solution as well, which is I finish the current activity after going to the next one. Is that the issue? Some of the activities are working well without any delay.
