Setting Android and Path environment variables on Mac OS X

When bash starts it reads the following files every time you login. For the purposes of OS X, this means every time you open a new Terminal window.

• /etc/profile
• ~/.bash_profile
• ~/.bash_login (if .bash_profile does not exist)
• ~/.profile (if .bash_login does not exist)

When you start a new shell by typing bash on the command line, it reads .bashrc

Finally, OS X also uses ~/.MacOSX/environment.plist to set more environment variables, including paths if necessary.

Add Android and PATH variables to ~/.profile, e.g.:

export ANDROID_HOME=/Users/cduu/Development/bin/android-sdk/android-sdk_r15-macosx_x86
export PATH=/Users/cduu/Development/bin/android-sdk/android-sdk_r15-macosx_x86/platform-tools:/Users/cduu/Development/bin/android-sdk/android-sdk_r15-macosx_x86/tools:$PATH

Check environment variables in a new Terminal with:

set

Using NTFS Filesystem with Mac OS X

Update:

Since a fresh Mac OS X 10.6.8 (Snow Leopard) installation the ntfs-3g solution didn’t work. I use NTFS Mounter to mount an external ntfs drive. It should also work with Leopard.

 

MacPorts helps a lot to install command-line, X11 or Aqua based open-source software on the Mac OS X operating system.

You can download MacPorts here. After installing MacPorts, download and unarchive NTFS-3G. Open a terminal, switch to the folder and type the following command:

sudo port install ntfs-3g

Java/Eclipse on Mac OS X: where is the source code for java

The JDK installed by default does not have a src.jar. But if you install the ‘Java Developer package’ from Apple, you will get /Library/Java/JavaVirtualMachines/1.6.0_26-b03-384.jdk, which has src.jar under Contents/Home.

• Download the latest Java Developer Package in the Apple Download Center for Developers and install it.

• After installing the JDK point to it from your IDE.

Uninstall Xcode

Use the following command to uninstall Xcode:

sudo <Xcode>/Library/uninstall-devtools --mode=all

<Xcode> is the location you’ve installed Xcode.
