i have important initialization when app starts. found best way put code inside oncreate() of class extends application class. class applicationdemo extends application{ public void oncreate(){ super.oncreate(); log.d("log", "inside oncreate()"); } } the problem i not find log statement executed every time app run. start app first time, log statement, close app , start again launcher. no, log statement doesn't come. what problem? how can ensure particular code run every time app run , before else performed? my guess have open application just once . i'm pretty sure that, after closed application, goes background, waiting put in foreground again. (it not created again, reuse have created.) try making sure killed process of application before re-opening it; make sure closed & reopen it, , not simple background-foreground thingy.

what sys.getsizeof return standard string? noticing value higher len returns. i attempt answer question broader point of view. you're referring 2 functions , comparing outputs. let's take @ documentation first: len() : return length (the number of items) of object. argument may sequence (such string, bytes, tuple, list, or range) or collection (such dictionary, set, or frozen set). so in case of string, can expect len() return number of characters. sys.getsizeof() : return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. so in case of string (as many other objects) can expect sys.getsizeof() size of object in bytes. there no reason think should same number of characters. let's have @ examples: >>> first = "first" >>> len(first) 5 >>> sys.getsizeof(first) 42 this example co...
