Android ndk learning records

The game project began to turn to Cocos2d-x for development. What ndk and cygwin do you need. Start learning with a hard head.

1. Download ndk, the latest version of R7. Decompress to D: \ develop, address: http://dl.google.com/android/ndk/android-ndk-r7-windows.zip

2. Project nativeCodePut in<Project>/JNI /...

3. Create<Project>/JNI/Android. mkDescription of navive code.

4. Compile native code:
CD <project>
<Ndk>/ndk-build

5.ProgramUse the code to load the compiled. So file in the class:

Static {
System. loadlibrary ("hello-JNI ");
}

Examples of the methods used in the class:

Public native string stringfromjni ();

6. android-ndk-r7 \ samples \ has sample code, hello-JNI runs successfully.

 

Compiling native code in cygwin is only in step 4. Install the following cygwin packages:

• Autoconf2.1
• Automake1.10
• Binutils
• Gcc-core
• Gcc4-core
• GDB
• PCRE
• PCRE-devel
• GNU awk

In D: \ cygwin \ home \ Administrator \. bash_profile, add:

Ndk =/cygdrive/D/develop/android-ndk-r7

Export ndk

Go to cygwin bash, enter the project directory, and use $ ndk/ndk-build to compile native code. Common Errors see http://www.chinavideo.org/archiver? Tid-10821.html

 

Ndk test is successful, the first step of the long journey, then configure cocos-2d.
