Performance when switching Android Activities

Question

There is an activity, in which the main button is and there is an OnClickListener for it:

 CustomView login_skip = (CustomView) findViewById(R.id.login_skip); login_skip.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { startActivity(new Intent(FirstLaunchActivity.this, MainActivity.class)); finish(); } });

The fact is that this code is executed for 3-5 seconds and only then a new Activity opened.

What could be the problem of speed?

Should I use Fragment instead of Activity ?

Apparently it's about the animation of the transition between activites.
There is nothing in your code that could take three seconds to execute.
The decision on the use of fragments is made from the justification of their use, which is impossible to judge from your question.

Try to remove the animation:

  overridePendingTransition(0, 0);

before finish()
