　　　　Chapter II: Building an Android Development Environment

What tools are needed for Android bottom-up development:

· JDK6 or the above version;

· Eclipse3.4 or the above version;

· ADT (for development Android applications);

· CDT (for development Android NDK procedures);

· Android SDK ;

· Android NDK ;

• Cross-compiling environment;

· Linux kernel source code;

· Android source code;

• Serial tool for debugging the Development Board:minicom.

Build an Android development environment:

(i) Installing the JDK:

Download the JDK 's tarball directly and unzip it, then enter it on the Linux terminal

# Getit/etc/profile

After you open the profile file, in the terminal input

Export path=.:/ (file compression directory) /bin: $PATH

After You save the profile file, enter it in the Linux terminal

# . /etc/profile

(ii) build an Android application development environment

1. Install Android SDK: Download Android SDK, get a tar file, After the terminal enters this directory, execute the command:

#tar-XVF Android-sdk+r16-linux.tar

2. Install Eclipse

#tar ZXVF Eclipse-sdk-3.7.1-win32-x86_64.zip

3. installing ADT

4. Configuring ADT

5. creating an AVD

(iii) installation of the Android NDK development environment:

1. Download Android NDK

#tar-XVF Android-ndk-r7-linux-x86.tar.tar

2. installing the CDT

3. command-line compiling Android NDK program

Ndk-build Command

4. examples of importing Android NDK

5. Configure the Android NDK integrated development Environment

(iv) Installation of cross-compilation environments

The CPU of the X86 architecture employs a complex instruction set computer. the CPU of the ARM architecture uses a thin instruction set computer. Since the CPUs of both architectures use different instruction sets, developing on the X86 architecture can be run on ARM A program on the schema must use a cross-compiler. Usually the cross compiler and related tools contain many executables and resources such as a large number of shared libraries and header files, a collection of which is called a cross-compilation environment.
