sendmessage - Android. Send text to facebook messenger by Facebook SDK 4.X -


as document facebook, can send image android app facebook messenger below.

string metadata = "{ \"image\" : \"trees\" }"; sharetomessengerparams sharetomessengerparams =     sharetomessengerparams.newbuilder(contenturi, "image/jpeg")             .setmetadata(metadata)             .build();  // sharing activity messengerutils.sharetomessenger(this, 0, sharetomessengerparams);

but want send text. tried below.

sharetomessengerparams sharetomessengerparams =     sharetomessengerparams.newbuilder(null, "text/plain")             .setmetadata("text send")             .build();  // sharing activity messengerutils.sharetomessenger(this, 0, sharetomessengerparams);

when tested this, java.lang.nullpointerexception: must provide non-null uri exception occurs.

how can send message facebook messenger..? using intent not available now, need use facebook sdk 4.x.

here facebook documentation

facebook (and messenger) doesn't not allow sharing text only.

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.
