android - Multiple MapActivitys in the stack -

-

i understand topic has been covered few times, , proposed solution having 'multiple' mapactivity classes run 1 in different processes. don't want this, i've got 3.

i've instead refactored 1 mapactivity subclass operate in 3 different modes.

 package com.rossgreenhalf.maptest.activity;  import android.os.bundle;  import com.google.android.maps.mapactivity;  public class mymapactivity extends mapactivity {      @override     protected void oncreate(bundle icicle) {     super.oncreate(icicle);      /* inflate xml view, set zoom etc */     }      @override     protected void onresume() {         super.onresume();          int mode = getintent().getextras().getint("map_mode");          switch(mode){         case 1:             /* markers show */             break;         case 2:             /* 1 marker */             break;         case 3:              /* showing location */             break;         }     }      @override     protected boolean isroutedisplayed() {     return false;     } }

i'm allowing multiple instances of mapactivity reside within task stack, it's launch mode still set 'standard'. approach seems work ok, , i'm not getting connection pool shutdown message seem get, i'm little confused whether multiple mapactivity instances exist or whether android reusing 1 automatically?

i getting error, don't know how serious is:

am taking correct approach this? should concerned error?

i got same problem , after searching found post same issue

https://novoda.lighthouseapp.com/projects/63622/tickets/157-leak-receiver-searchresult

it suggests problem rises when using multiple map activities within application.

so in manifest.xml file of app made each map activity run in separate process:

android:process=":p1" android:process=":p2"

you can read more in android docs. http://developer.android.com/guide/topics/manifest/activity-element.html#proc

i trying use snmp4j snmp bulkget. when ever use snmp4j make call returned responseevent error says "general variable binding error" , data returned equal null. to debug: print out, console, exact oid , version number using in snmp4j. use printed out data snmpwalk on command line. valid results. know sending snmp4j correct pdu correct oid, version number, max repititions, etc. i have used snmp4j , code wrote succesffuly monitor other devices years. don't know different time. leaving me stumped. why "general variable binding error?" causes error? ideas debug? can reproduced? if so, first action should using wireshark or microsoft network monitor capture network packets. my guess agent gives generr response, not surprising, http://www.ietf.org/rfc/rfc1157.txt
