Android Studio - android-4.2.2/dx failed when importing Facebook Android SDK

-
Problem

Got this error in Android Studio while following Getting Started with the Facebook SDK for Android (Android Studio) tutorial on Facebook.

Gradle: Execution failed for task ':HelloWorldAndroid:dexDebug'.
> Running /Applications/Android Studio.app/sdk/build-tools/android-4.2.2/dx failed. See output




Solution

1. Use latest Android Gradle Plugin

First, in order to use the most recent version of the Android Gradle Plugin, change all occurences of Gradle classpath in build.gradle file.

buildscript {
  dependencies {
    classpath 'com.android.tools.build:gradle:0.4'
  }
}


to

buildscript {
  dependencies {
    classpath 'com.android.tools.build:gradle:0.4.+'
  }
}


2. Install Android Repositories

Make sure the following components of Android SDK are installed:

  1. Android Support Repository
  2. Google Repository



3. Change the reference for Android Support library

The correct way to reference to Android Support Library is shown below. (Instead of referencing android-support-v4.jar files in every library.

dependencies {
    compile files('libs/android-support-v4.jar')
}


to

dependencies {
    compile 'com.android.support:support-v4:13.0.0'
}



That's it! Your project should be able to compile and run without error!

THE PROBLEM I've deployed a REST API application ( CodeIgniter with Phil Sturgeon's Rest-Server library ) on Azure Websites.

And thus all requests to the server failed with the error message: Origin http://example.azurewebsites.net is not allowed by Access-Control-Allow-Origin.   In order to make sure there's no problem with my application, I've deployed the same code to Appfog.com . And as expected, the application works just fine. The same application d...

[Magento] Create Contact Form with Dynamic Recipient

-
There are many ways of creating contact forms to email to multiple recipient. I'm going to describe a way that uses Javascript a the frontend to change the target recipient. Advantage of this method: Easy to add in new emails in the future. Disadvantage of this method: For those who are particularly concern email privacy, you might not want to use this method. You can modify the email checking to the backend (controller) instead. Okay enough talking, lets get started. Step 1: Set up HTML form fields I'm going to use an example of drop down select to change the email. Of course, this is fairly easy to modify with other forms as well. Open up app/design/frontend/default/<theme>/template/contacts/contacts.phtml Insert the following snippets anywhere between the <form>...</form> tag. <select name="interest" id="interest" title="<?php echo Mage::helper('contacts')->__('Please select department t...
