Android ane written in C language for flash (local extension)

Use the flex SDK 4.6, Android-ndk, and running environment fedora 17 (in Windows ).

I will not talk about the installation and configuration of flex and Android-ndk. There are many articles on the Internet.

Original Works. retain original author information during reprinting.

1. Create a JNI folder in the working directory, and copy the android/flashruntimeextensions. So file in the lib directory of the Flex SDK, and flashruntimeextensions. h In the include directory to the JNI directory.

2. Create a makefile in the JNI Directory: Android. mk

Include $ (clear_vars) local_module: = flashlocal_src_files: = flashruntimeextensions. soinclude $ (prebuilt_shared_library) include $ (clear_vars) local_module: = mylocal_shared_libraries: = flashlocal_src_files: = test. C # Code include $ (build_shared_library) whose source code is 3rd)

3. Write the C code test. C:

#include<FlashRuntimeExtensions.h>#include <stdlib.h>#include <string.h>FREObject test(FREContext ctx,void*funcData,uint32_t argc,FREObject argv[]){               const uint8_t* msg = (const uint8_t*)"Hello world!!!!";        FREObject retObj;        FRENewObjectFromUTF8(strlen((const char*)msg)+1, msg, &retObj);        return retObj;}void ContextInitializer(void* extData, const uint8_t* ctxType,FREContext ctx,uint32_t* numFunctionsToTest,const FRENamedFunction** functionsToSet){        *numFunctionsToTest= 1;        FRENamedFunction*func = (FRENamedFunction*)malloc(sizeof(FRENamedFunction)*1);        func[0].name= (const uint8_t*)"test";        func[0].functionData= NULL;        func[0].function= &test;        *functionsToSet= func;}void ContextFinalizer(FREContext ctx) {        return;}void ExtInitializer(void** extDataToSet, FREContextInitializer* ctxInitializerToSet,FREContextFinalizer* ctxFinalizerToSet){        *extDataToSet= NULL;        *ctxInitializerToSet= ContextInitializer;        *ctxFinalizerToSet= ContextFinalizer;}void ExtFinalizer(void* extData){        return;}

 

4. Generate the libmy. So file:

Run ndk-build in the JNI directory

You can find libmy. So in OBJ/local/armeabi/, indicating that the compilation is successful,

5. The configuration file of ANE (New myane. XML in the current working directory ):

<extension xmlns="http://ns.adobe.com/air/extension/3.1"><id>libiao.MyExtension</id><versionNumber>1.0.0</versionNumber><platforms><platform name="Android-ARM"><applicationDeployment><nativeLibrary>libmy.so</nativeLibrary><initializer>ExtInitializer</initializer><finalizer>ExtFinalizer</finalizer></applicationDeployment></platform></platforms></extension>

 

6. Flash interface file (New myextension. As in the current working directory ):

package{        import flash.events.EventDispatcher;        import flash.external.ExtensionContext;        public class MyExtension extends EventDispatcher        {                private static var context:ExtensionContext;                public function MyExtension()                {                        super();                        try                        {                                context= ExtensionContext.createExtensionContext("libiao.MyExtension","");                        }catch(e:Error){}                }                public function say():String                {                        var str:String = context.call("test") as String;                        return str;                }        }}

 

7. Generate the SWC file (run in the current directory ):

Acompc-source-path.-include-classes myextension-SWF-version = 14-output myextension. SWC

8.use unzips to decompress library.swfin myextension.swc, create a new file folder extension, and put the libmy. So files under library.swf and OBJ/local/armeabi/into the extension folder.

9. Generate the ANE file (helloworld. ane) and run it in the same level directory of extendsion:

ADT-package-target ane helloworld. Ane myane. XML-SWC *. SWC-platform Android-arm-C extension.

10. Use ANE in Flash as3:

Main.:

package{        import flash.display.Sprite;        import flash.text.TextField;        /**         * ...         * @author db0@qq.com         */        public class Main extends Sprite        {                private var ext:MyExtension = new MyExtension();                private var ta:TextField = new TextField();                public function Main():void                {                        addChild(ta);                        ta.text = ext.say();                }        )     }

 

11. Generate the SWF file:

Amxmlc main. As-library-path + = myextension. SWC-DEBUG = true-output test.swf

12. Air configuration file my-app.xml:

<application xmlns="http://ns.adobe.com/air/application/3.1"><supportedProfiles>mobileDevice</supportedProfiles><extensions><extensionID>libiao.MyExtension</extensionID></extensions><id>ExtensionTest</id><filename>ExtensionTest</filename><name>ExtensionTest</name><versionNumber>1.0.0</versionNumber><initialWindow><content>Test.swf</content><visible>true</visible><systemChrome>none</systemChrome><transparent>false</transparent><minimizable>false</minimizable><maximizable>false</maximizable><resizable>false</resizable><aspectRatio>landscape</aspectRatio><autoOrients>false</autoOrients><renderMode>auto</renderMode></initialWindow><android><manifestAdditions><![CDATA[<manifest><uses-permission android:name="android.permission.INTERNET"/><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/><uses-permission android:name="android.permission.READ_PHONE_STATE"/><uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/><uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/><uses-permission android:name="android.permission.CAMERA"/><uses-permission android:name="android.permission.RECORD_AUDIO"/><uses-permission android:name="android.permission.DISABLE_KEYGUARD"/><uses-permission android:name="android.permission.WAKE_LOCK"/><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/><uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/></manifest>]></manifestAdditions></android></application>

 

13.package into apk(main.apk ):

ADT-package-target APK-storetype PKCS12-key store my. p12-storepass FD main.apk my-app.xml-extdir. test.swf

14.run main.apk on your mobile phone. You can see helloword !!!, Congratulations! You're done.
