Using LayoutInflater will increase the time to load the UI. The same functionality can be used with <include/> and onFinishInflate(). It's better to remove the LayoutInflater used at various places.
This will help startup time
Created attachment 579872 [details] [diff] [review] Patch This patches uses <include/> and removes the LayoutInflation from most places. While using profiler, I saw some performance win. Generally there is around 50-150ms faster UI on Nexus S and 5-20ms faster UI on Nexus. The "onFinishInflate()" is called twice in pre-Honeycomb (or pre-ICS) phones -- reported here: http://www.androidadb.com/source/payforwarding-read-only/source/Android/GreenDroid/GreenDroid/src/greendroid/widget/ActionBar.java.html I have a guard for the same.
