Optimizing launch time for Android app

Question

My App contains a single activity and a fragment with listView.

The listview items (not more than 5) are being loaded from SQLite. Each item comprises of 3 TextView and an ImageView.

But still it is taking more than one second to load the app.

Can someone please suggest some tips to decrease launching time of Android App.

Code Flow:

onCreate method of Activity:

super.onCreate()
// finding two views by ID
// initialising fragment Manager
// initialising toolbar
// setting toolbar as supportactionbar
// fileHandle initialization
// databasehandle initialization 

if (condition using filehandle) {
    // add fragmentA
} else {
   if (condition using databasehandle) {
      // add fragmentB
   } else {
      // add fragmentC
   }
   // update the filehandle
}
