I can't get Apache Ignite.NET to start up properly inside my .NET application -


i keep getting null reference exception when try create new igniteconfiguration instance. how create configuration:

var cfg = new igniteconfiguration                 {                     // explicitly configure tcp discovery spi provide list of initial nodes                     // first cluster.                     discoveryspi = new tcpdiscoveryspi                     {                         // initial local port listen to.                         localport = 49500,                         // changing local port range. optional action.                         localportrange = 2,                         ipfinder = new tcpdiscoverystaticipfinder                         {                             // addresses , port range of nodes first cluster.                             // 127.0.0.1 can replaced actual ip addresses or host names.                             // port range optional.                             endpoints = { "127.0.0.1:49500..49520" }                         }                     },                     // explicitly configure tcp communication spi changing                      // local port number nodes first cluster.                     communicationspi = new tcpcommunicationspi                     {                         localport = 49100                     }                 };

the exception details don't have inner exception , message says "object reference not set instance of object."

when try start ignite using web.config configuration works unless try explicitly set port. example, working configuration:

<igniteconfiguration xmlns="http://ignite.apache.org/schema/dotnet/igniteconfigurationsection" localhost="127.0.0.1" peerassemblyloadingmode="currentappdomain"> <atomicconfiguration atomicsequencereservesize="10" /> <autogenerateigniteinstancename>true</autogenerateigniteinstancename> <discoveryspi type="tcpdiscoveryspi" localport="49500" localportrange="2">   <ipfinder type="tcpdiscoverystaticipfinder">     <endpoints>       <string>127.0.0.1</string>       <string>127.0.0.1:49500..49502</string>     </endpoints>   </ipfinder> </discoveryspi>

however, have need not use mutlicast broadcast , need set explicit port. configuration ends using default port. according documentation can this:

<igniteconfiguration xmlns="http://ignite.apache.org/schema/dotnet/igniteconfigurationsection" localhost="127.0.0.1" peerassemblyloadingmode="currentappdomain"> <atomicconfiguration atomicsequencereservesize="10" /> <autogenerateigniteinstancename>true</autogenerateigniteinstancename> <discoveryspi type="tcpdiscoveryspi" localport="49500" localportrange="2">   <ipfinder type="tcpdiscoverystaticipfinder">     <endpoints>       <string>127.0.0.1</string>       <string>127.0.0.1:49500..49502</string>     </endpoints>   </ipfinder> </discoveryspi> <communicationspi type="tcpcommunicationspi" localport="49500" localportrange="2" />

setting port explicitly 49500, using configuration application not start, hangs @ ignite.startfromconfiguration() step.

so can't use web.config create instance nor can programmatically start because of null reference exception.

anyone have ideas?

endpoints list of addresses, should initialized new[] {...}. see example here: https://apacheignite-net.readme.io/v2.1/docs/configuration#section-c-code

as second issue, you're trying set same port discovery , communication, doesn't make sense. different protocols , should use different, non intersecting ranges of ports.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
