i getting weird error in androidmanifest.xml file saying "mainactivity not public. validate resource reference inside android xml files." not know how solve error. can me here? androidmanifest.xml <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.pixalstudio.javaclasses" > <uses-permission android:name="android.permission.access_network_state" > </uses-permission> <application android:allowbackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:theme="@style/apptheme" > <activity android:name=".mainactivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.

i've found great example here: https://developers.google.com/analytics/solutions/articles/data_over_time uses google.gdata, not google.api. credentials asking following: private static final string username = "username"; private static final string password = "password"; private static final string table_id = "table_id"; whereas in google.api, credentials needed following: private static final string key_file_location = "yourfile.p12"; private static final string service_account_email = "something@developer.gserviceaccount.com"; these 2 libraries (google.api , google.gdata) seem able similar things in fact different. meant username, password , table_id in first scenario? recommended java api google analytics? it recommended use google analytics java client libraries . example have pointed uses deprecated client login . you should use updated hello analytics api tutorial better example of using java api googl

i realize reading .csv file removes leading zeros, of files, maintains leading zeros without having explicitly set colclasses in read.csv. on other hand, what's confusing me in other cases, remove leading zeros. question is: in cases read.csv remove leading zeros? the read.csv , read.table , , related functions read in character strings, depending on arguments function (specifically colclasses , others) , options function try "simplify" columns. if enough of column looks numeric , have not told function otherwise, convert numeric column, drop leading 0's (and trailing 0's after decimal). if there in column not number not convert numeric , either keep character or convert factor, keeps leading 0's. function not @ entire column make decision, may obvious not being numeric may still converted. the safest approach (and quickest) specify colclasses r not need guess (and not need guess r going guess).

new mvc--was never of front-end web developer (mostly backend), i'm not privy design on front-end. now, i'm trying use mvc without original webform knowledge...that being said, please give me pointers/links/good ideas on how handle following: i have textbox field want show/hide based on checkbox. have these fields in view @using (html.beginform()... should change attribute on text box in javascript or controller action? if use javascript, i'm having hard time getting values in beginform, if use controller action, i'm not sure how/what pass to/from in controller action. i using jquery if want manipulate dom. here example - view @using (html.beginform()) { @html.checkboxfor(model => model.mybooleanvalue) <br /> @html.textboxfor(model => model.mytextvalue) <br /> <input type="submit" value="submit" /> } <script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.j

i'm using python 2.7, , i'm trying write gui, having issues buttons. have running properly, assuming i've made mistake inputs or something, i'd way stop running function after hitting "go" button. code way long post here, simple example below. how make "stop" button break start function, not quit window entirely? maybe threading? i'm sort of new writing guis, , i'm not programmer, isn't area of expertise. the gui totally unresponsive while main function running. there must way simultaneously run function while allowing me change things in gui , hit buttons, i'm not sure how works. updates don't have implemented until next time "go" button hit though. import time tkinter import * class example: def __init__(self,master): self.startbutton = button(master,text='start',command=self.start) self.startbutton.grid(row=0,column=0) self.stopbutton = button(master,text='stop'

when reading mono docs , says xsp not suited production: for getting started, familiar mono , asp.net, xsp ideal solution. keep in mind xsp limited server , useful acquainted asp.net , mono, support http 1.0 , not provide extensibility or configuration. we developing rest api, , thinking of following setup: linux server asp.net mono run in xsp4 nginx reverse proxy (which can handle load balancing, caching, static files, etc.) but i'm wondering whether remarks xsp not suited production apply configuration part, or performance? our performance demands large requests, not processing high number of requests (but if necessary, scale multiple instances of application in xsp4).

from can tell from list , there no dedicated nginx variable check if client connecting via ipv4 or ipv6, since server supports both. i'd set variable pass php within fastcgi.conf so: fastcgi_param ip_version $ip_version is there way determine ip version without using evil ifs , pass along? i'm aware can perform check within php, we'd use nginx if possible, while still maintaining stellar performance.

i want build 2 similar dictionaries same csv file (one mapping row[0] row[5], 1 row[0] row[6]. reason, can build one. whichever of these 2 lines run first, dictionary exists , want. other empty. no idea what's going wrong. mydict = {row[0]:row[5] row in csv.reader(g)} mydict1 = {row[0]:row[6] row in csv.reader(g)} i using python 3, , tried changing dictionary name , few other things. you cannot iterate on file twice without rewinding start. doing not efficient either; better not use dictionary comprehensions here: mydict1, mydict2 = {}, {} row in csv.reader(g): mydict1[row[0]] = row[5] mydict2[row[0]] = row[6] if insist, can use file.seek(0) put file pointer start; don't need re-create reader here: reader = csv.reader(g) mydict1 = {row[0]:row[5] row in reader} g.seek(0) mydict2 = {row[0]:row[6] row in reader}

i have inventory system stores "item" types abstract class. have derived class called "skates". program allows user add "skates" vector of "item" pointers. user input model , id of skates , create "skates" object parameters. use "item" pointer point "skates" object , add vector. when user wants edit "skates" object have dynamic_cast "skates" object , edit it. std::vector<item*> itemcollection; item * item = new skates("model1", 1); itemcollection.push_back(item); //to retrieve skates * skatestoedit = dynamic_cast<skates*>(itemcollection[0]); the problem facing account new derived class, "skateboard" class example. don't want create new method handle editing of "skateboard" class like: skateboard * skateboardtoedit = dynamic_cast<skateboard*>(itemcollection[0]); since mean everytime make new derived class need write same style of code

i installed phonegap first time , browsed through docs. confuses me fact docs using command "phonegap" , "cordova". android platform guide: $ cordova create hello com.example.hello "helloworld" command line interface guide tells: $ phonegap create hello com.example.hello helloworld is there difference between 2 commands (resulting in different files , folder structures) or aliases same thing? http://phonegap.com/blog/2012/03/19/phonegap-cordova-and-whate28099s-in-a-name/ i think url explains need. phonegap built on apache cordova nothing else. can think of apache cordova engine powers phonegap. on time, phonegap distribution may contain additional tools , thats why differ in command same thing. edit: info added command difference , phonegap can while apache cordova can't or viceversa first of command line option of phonegap http://docs.phonegap.com/en/edge/guide_cli_index.md.html apache cordova options http://cordova.a
