android - Why is my Activity runs from the top again when resumed instead of doing nothing? -


i have activity displays table database. when press power button turn off screen, pressing power button again resume activity, table loads again , did on create. why activity running again when resume it?

i put onresume() , left blank/default.

@override protected void onresume() {     super.onresume();  }

accordingly, call methods according follows, never call oncreate() data reloaded,

on launching activity call --> oncreate(), onstart(), onresume(),

onpower key off --> onpause(), onstop()

onpower key on --> onrestart(), onstart(), onresume()

to prevent reloading data there many cases this , this link

may due :

android:configchanges="orientation|keyboardhidden|screensize"

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
