android - WebView - memory leaks in a simple code on devices <= 4.1 -


my test code:

public class myactivity extends appcompatactivity {     webview mywebview;     relativelayout webviewlayout;      /** called when activity first created. */     @override     public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.mylayout);         webviewlayout = (relativelayout) findviewbyid(r.id.webviews);         mywebview = new webview(this);         webviewlayout.addview(mywebview);     } }

causes memory leak in webview on 4.1 device (i use mat analysis):

class name java.lang.thread @ 0x4212f6b8 webviewcorethread thread '- <java local>, target android.webkit.webviewcore$webcorethread @ 0x4205d390 '- core android.webkit.webviewcore @ 0x4212f608 '- mcontext com.packagename.myactivity

i have added ondestroy():

@override public void ondestroy() {     webviewlayout.removeallviews();     if(mywebview != null) {         mywebview.removeallviews();         mywebview.onpause();         mywebview.getsettings().setjavascriptenabled(false);         mywebview.destroy();         mywebview = null;     }     super.ondestroy(); }

but on 4.1 memory leak remains. tried use getapplicationcontext() instead [this], result same.

on 4.4 device no memory leaks. bug in webview on <=4.1 ? possible fix it?

thanks!

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
