Build an android ndk development environment in Ubuntu

HowBuild an android ndk development environment in UbuntuWhat about it? The following is a step-by-step tutorial.

Step 1. Download ndk (note that I downloaded the R4 version ):

Http://dl.google.com/android/ndk/android-ndk-r4b-linux-x86.zip

 

Step 2. After the download is complete, decompress it ~ /Directory:

$Echo $ home<-- View the current user directory, that is ~ /Directory path

/Home/wzhnsc

$PWD<-- View the current path

/Home/wzhnsc/android-ndk-r4b

Note: The above path is the android-ndk-r4b-linux-x86.zip directory path after I unzip the android-ndk-r4b

Step 3.First, enter the/home/wzhnsc/android-ndk-r4b directory,

This directory contains a readme. txt file, which mentions:

In the docs/STABLE-APIS.TXT is the APIS documentation,

How to install ndk in docs/install. txt

(Previous versions all need to run build/host-setup.sh for initialization,

This android-ndk-r4b version removes it, it is more convenient to use, Just configure the environment variables as follows ),

How to Use ndk in docs/howto. txt.

Note: It is recommended that you read all these documents for a rough understanding.

Step 4. Configure environment variables for ndk

$Gedit ~ /. Bashrc

Note: add the following content at the end of the opened file:

Ndk = ~ Android-ndk-r4b

Export ndk

Step 5. Read and execute in the current bash environment ~ /. Bashrc command:

$Source ~ /. Bashrc

Or (the source command is also called the "dot command", that is, a dot symbol (.).)

$.~ /. Bashrc

Step 6. Then, check whether it takes effect:

$Echo $ ndk

/Home/wzhnsc/android-ndk-r4b/

Step 7There are two ways to compile:

1) compile in the target project directory:

$CD/home/wzhnsc/android-ndk-r4b/samples/Hello-JNI

Enter the example directory

$Ndk/ndk-build

Then run the/home/wzhnsc/android-ndk-r4b/ndk-build script in the current directory

 

2) Compile in any directory:

$Ndk/ndk-Build-C/home/wzhnsc/android-ndk-r4b/samples/Hello-JNI

Use-C to point out the project directory path

 

Note: No matter which one is compiled, after successful compilation, the libs and OBJ subdirectories will be generated in the current directory.

 

Step 8. Open eclipse and import the hello-JNI project to see the effect.
