Cocos2d-x and Android mixed encoding for "avatar pictures"

Recently, I took over the personalized features of players, but it is hard to handle this problem by replacing the player's "Avatar" operation. After searching, we finally found the solution.

If you change the player's "Avatar" operation, you can call the local images in the android servers service, select and crop the images, and crop the images to upload them to the server, this allows you to change user portraits;

Then, we need to use JniHelper to call classes and methods in andriod java to achieve mixed encoding to meet our various requirements for operating the android system, such:Obtain the MAC address of the Local Machine and the name of the Local MachineYou can even perform complex operations on the android background services;

To put it bluntly, we need to compile the android Activity class. The main function of this class is to call the android local image, select, crop, and crop the game and upload the image to the server. Let's take a look at my directory structure:

Ui of the userinfo. xml View File:

Android platform, game entry Cocos2dxActivity (GuideLayer), as follows:

Public class GuideLayer extends Cocos2dxActivity {protected void onCreate (Bundle savedInstanceState) {super. onCreate (savedInstanceState);} public Cocos2dxGLSurfaceView onCreateView () {Cocos2dxGLSurfaceView glSurfaceView = new response (this); // GuideLayer shocould create stencel buffer surglfaceview. setEGLConfigChooser (5, 6, 5, 0, 16, 8); return glSurfaceView;} static {System. loadLibrary ("cocos2dcpp");} // execute the android page Jump to jump to my function class UserInfoActivity. java; public static Object gotoActivity () {Intent in = new Intent (GuideLayer. getContext (), UserInfoActivity. class); GuideLayer. getContext (). startActivity (in); return null ;}}

This is a static class; the return type is Object, but I don't need to return the value, because I execute the page Jump, if my need is to get the value of the android module code, you can enter the corresponding return type to transfer values between java and c ++;

Handle Avatar change function: UserInfoActivity. java

Because we call an android Avatar and need to use the camera function, we can also enable this function. Add the following code in AndroidManifest. xml:

There is also a class, the activity Configuration:

OK, go to the win32 platform:

In HelloWorldScene. cpp, introduce:

#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)#include 
 
  #include "platform/android/jni/JniHelper.h"#include #if 1#define  LOG_TAG    "JniHelper"#define  LOGD(...)  __android_log_print(ANDROID_LOG_DEBUG,LOG_TAG,__VA_ARGS__)#else#define  LOGD(...)#endif#endif
 

Code for triggering jump:

Void HelloWorld: menuCloseCallback (CCObject * pSender) {CCLog ("change the Avatar after a player clicks"); # if (CC_TARGET_PLATFORM = CC_PLATFORM_ANDROID) JniMethodInfo minfo; jobject; // The getStaticMethodInfo method calls the static class, or you do not need to call the getMethodInfobool B = JniHelper: getStaticMethodInfo (minfo, "com.GuideLayer.org. guideLayer ", // class path" gotoActivity ", // static method name" () Ljava/lang/Object; "); // parameters are in brackets, the following is the return value. If (! B) {CCLog ("JniHelper: getMethodInfo error... ");} else {CCLog (" ready to invoke method... "); jobj = minfo. env-> CallStaticObjectMethod (minfo. classID, minfo. methodID) ;}# endif}

OK. The effect is as follows:
