PHP SoapClient: Function ("hoge") is not a valid method for this service. / SoapServer: Procedure "hoge" not present

SoapClient

$client = new SoapClient("http://www.example.com/soap");
$client->hoge("fuga"); // <-exception occurred!

Exception Message

Function ("hoge") is not a valid method for this service.

but...

SoapServer

Of course, WSDL definitions are correct (Function 'hoge' is added).

$server = new SoapServer("http://www.example.com/soap");
$server->handle(); // <-exception occurred!

Exception Message

Procedure "hoge" not present

set soap.wsdl_cache_enabled to 0.

Add below, Both SoapClient and SoapServer.

SoapClient

ini_set("soap.wsdl_cache_enabled", 0);
$client = new SoapClient("http://www.example.com/soap");
$client->hoge("fuga"); // <-exception occurred!

SoapServer

ini_set("soap.wsdl_cache_enabled", 0);
$server = new SoapServer("http://www.example.com/soap");
$server->handle(); // <-exception occurred!

Eclipse Kepler PDT auto completion not work

shutdown your eclipse,

$ rm -rf workspace/.metadata/.plugins/org.eclipse.dltk.core.index.sql.h2/

and start your eclipse again.

see also:

Intent com.android.camera.action.CROP ActivityNotFoundException

Intent intent = new Intent("com.android.camera.action.CROP");

    /* Not work. ActivityNotFoundException occurs. */
    //intent.setType("image/*");
    //intent.setData(uri);

    intent.setDataAndType(uri, "image/*"); // works!

    startActivityForResult(intent, REQUEST_CODE_IMAGE_CROP);

日本でも使えますよ？Chromecastの設定用apkを入手する

Googleのスマホ連携用HDMIスティック「Chromecast」が直輸入、ただし…

ただし、現時点ではChromecast用アプリを国内のGoogle Play/iTunesアカウントから入手することができず、使用するのは難しい状態。どちらのアカウントでも「このアプリは日本では利用できない」という旨のメッセージが表示され、端末にアプリを導入することはできなかった。

そう、正規ルートだとChromecast設定用アプリを入手することは出来ない。けど、

■ Chromecastの設定APKは落ちている

こちらでも紹介されてるし、APKの直リンはここ。

■ Chromecastマジで(・∀・)ｲｲ!!

twitpic "Could not authenticate you (header rejected by twitter)."

twitpic

なんか知らないんだけどtwitpicっていうのを使っているサービスがあって、今更、例のtwitter API 1.1対応みたいなお仕事したんですが、twitpicのAPIを叩くと、

Could not authenticate you (header rejected by twitter).

って言われちゃう。
なのでtwitpicのAPIドキュメントのこれ↓
http://dev.twitpic.com/docs/2/upload/
をみたところ、

X-Verify-Credentials-Authorization (Required)
Header Example
1 OAuth realm="http://api.twitter.com/",
2 oauth_consumer_key="GDdmIQH6jhtmLUypg82g",
3 oauth_signature_method="HMAC-SHA1",
4 oauth_token="819797-Jxq8aYUDRmykzVKrgoLhXSq67TEa5ruc4GJC2rWimw",
5 oauth_timestamp="1272325550",
6 oauth_nonce="oElnnMTQIZvqvlfXM56aBLAf5noGD0AQR3Fmi7Q6Y",
7 oauth_version="1.0",
8 oauth_signature="U1obTfE7Rs9J1kafTGwufLJdspo%3D"  

X-Auth-Service-Provider (Required)
https://api.twitter.com/1/account/verify_credentials.json

って書いてあるんだけど、X-Auth-Service-Providerを

https://api.twitter.com/1.1/account/verify_credentials.json

にするのはもちろん、oauth_signatureを作っているURLも

https://api.twitter.com/1.1/statuses/update.json

とかにする必要があったです。はい。

バカとか低学歴とか

バカとか低学歴とかそういう問題じゃない気がする。
twitter社もしくは使っていたアプリが不案内なんだと思う。

もしくはインターネッツそのものが。

バカなの？低学歴なの？

APK Expansion Files

Development environment.

Ubuntu 11.10 (Oneiric)
JDK 1.6.0_24-b07
Eclipse 3.7.3 (Indigo)
- Android Development Toolkit 17.0.0

Preparing.

Get a publisher account here for Google Play, if you don't have yet.
Download two packages from the SDK Manager.('Google Play APK Expansion Library' and 'Google Play Licensing Library')

Android SDK Manager
Create two library projects from existing source.
- <sdk>/extras/google/play_apk_expansion/downloader_library
- <sdk>/extras/google/play_licensing/library
Create a new project which you want to use APK Expansion Files and add above two library project to your new project's build path.

Add a reference to a library project

Implementing.

Downloader service.

// Extends com.google.android.vending.expansion.downloader.impl.DownloaderService class and override three methods.
public class ExpansionFileDownloaderService extends DownloaderService {
 // the Base64-encoded RSA public key for your publisher account
 private static final String PUBLIC_KEY = "{YOU_PUBLIC_KEY}";
 // Generate 20 random bytes, and put them here.
 private static final byte[] SALT = new byte[] {};
 @Override public String getPublicKey() {
  return PUBLIC_KEY;
 }
 @Override public byte[] getSALT() {
  return SALT;
 }
 @Override public String getAlarmReceiverClassName() {
  return ExpansionFileAlarmReceiver.class.getName();
 }
}

Alarm receiver.

public class ExpansionFileAlarmReceiver extends BroadcastReceiver {
 @Override public void onReceive(Context context, Intent intent) {
  try {
   DownloaderClientMarshaller.startDownloadServiceIfRequired(
     context, intent, ExpansionFileDownloaderService.class);
  } catch (NameNotFoundException e) {
   Log.e("apk-expansion-files", "NameNotFoundException occurred. " + e.getMessage(), e);
  }
 }
}

Main activity.

@Override

     this, 0, fromNotification, PendingIntent.FLAG_UPDATE_CURRENT);
   try {

    int result = DownloaderClientMarshaller.startDownloadServiceIfRequired(
      this, pendingIntent, ExpansionFileDownloaderService.class);
    if (DownloaderClientMarshaller.NO_DOWNLOAD_REQUIRED != result) {
     // implement Downloading UI.
     return;
    }
   } catch (NameNotFoundException e) {
    Log.e("apk-expansion-files", "NameNotFoundException occurred. " + e.getMessage(), e);
