Cocos2d-x learning Tour (4): 1.4 using eclipse to compile Android C ++

Preparation

The android development environment has been configured in the previous chapter. Let's compile and run the hello-JNI example today.

Project path: D: \ android-ndk-r8b \ samples \ hello-JNI

Step 1: import the hello-JNI project to eclipse

Open eclipse and choose File> New> Project> Android project from exsiting code.

Click Next, select the hello-JNI directory in ndk, and click Finish to finish the import.

Now let's take a look at the project file structure. The JNI directory is the c ++ we need to compile.

Deploy hellojni on the android simulator. Right-click the project and choose run as> Android Application. An error occurs during running.

It seems that the cygwin we installed has not been used yet. Now we can use it to compile C ++. Right-click the project, select Properties, open the project properties, and select the builders tab, click new to enable cygwin compiler.

Follow the settings below

Location: D: \ cygwin \ bin \ bash.exe

Working directory: D: \ cygwin \ bin

Arguments: -- login-c "CD/cygdrive/D/android-ndk-r8b/samples/Hello-JNI & ndk-build"

Switch to build options and follow the settings below to clear the compiled so file and generate it again.

Link to the APK file.

Move the ndk_builder to the top

The following figure shows the successful running interface.
