android - UnsupportedOperationException on EdgeEffect -


my app fails when initializing viewpager inflated xml. following line crashes android src edgecompat.java

final typedarray = context.obtainstyledattributes(com.android.internal.r.styleable.edgeeffect); final int themecolor = a.getcolor(com.android.internal.r.styleable.edgeeffect_coloredgeeffect, 0xff666666);

this called viewpager.initviewpager() , can see in stack trace there error when inflating layout.

i have attached layout , stack trace below

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.
