nsusernotification - NSUserNotificationCenter not showing notifications -

-

i'm not sure if got wrong examples find. wrote little helloworld.

#import <foundation/foundation.h> #import <foundation/nsusernotification.h>   int main (int argc, const char * argv[]) {     nsusernotification *usernotification = [[nsusernotification alloc] init];     usernotification.title = @"some title";     usernotification.informativetext = @"some text";      [[nsusernotificationcenter defaultusernotificationcenter] delivernotification:usernotification];      return 0; }

i compile with:

cc -framework foundation -o app main.m

it compiles , can execute won't show anything. reasons, nothing gets presented. read notifications may not displayed if application main actor. how can make show notification?

set delegate , overwrite

- (bool)usernotificationcenter:(nsusernotificationcenter *)center                                 shouldpresentnotification:(nsusernotification *)notification {   return yes; }

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
