Edit your vedio online

Try to camera my own video for some demo. The most convenient tool is mobile phone.
After recording video, the file format is 3GP and the video is needed to rotate 90 degree.
Ha, it's easy to edit online. Just upload to Youtube then use Youtube editor.
The video also can set to private use.

[Android] Please ensure that adb is correctly located at 'C:\Program Files\Android\android-sdk-windows\platform-tools\adb.exe' and can be executed.

If you get the error message "Please ensure that adb is correctly located at 'XXX\platform-tools\adb.exe' and can be executed.", just check the path setting in your computer environment for Microsoft Windows Operation System.

The adb in tools/ is moved to platform-tools/ for new SDK version.
Add the real path to your path environment.

[Android] Simple way to set up development environment

It is recommended to use Eclipse.

First take time to read Android Official training materials here. http://developer.android.com/training/basics/firstapp/index.html

1. Because Android is Java based, Java SDK is needed to install.
    Better to choice the second latest version if possible. The newest version may have some bugs issue.

2. Download and install Eclipse. (The version is better newer because old version that Android SDK may not support)

3. Run Eclipse and install ADT (Android Development Tool)
    Help --> Install new software -->
   Paste the address http://dl-ssl.google.com/android/eclipse/site.xml then you can install the ADT.

4. Check Android version of your Android phone then update SDK if necessary by Android SDK Manager.

5. Set up Android Path. Eclipse --> Windows --> Preference --> Android
    For my case, I install SDK here.  C:\Android\android-sdk

6. Follow the tutorial to build your first App "Hello world".

Use textedit to open project.pbxproj and remove XXX string.
Then re-open Xcode and build then it should work again.
