Android/Cocos2d-x unsatisfiedlinkerror using JNI using Java to call C++ -


edit: i've solved problem (and found next issue in long line of jni tribulations!) changing following:

delete "static" declaration of native method in both java , c++, add java method instance of simplegame class, , calling

public static void callcppapiresponse (string result, string token, long context) { **getinstance()**.cppandroidapiresponse(token, 200, result, result.length(), context); }

now information makes java c++. may else similar issue.

original post:

i'm using cocos2d-x platform , writing c++ code cross-platform ios/android app, , there methods need handled respective native ios/android systems, need able call java c++ call c++ java.

i able load shared library app , trigger java response c++, when try call c++ java following logcat output , app crashes:

dalvik vm     no implementation found native lorg/cocos2dx/simplegame/simplegame; cppsideandroidapiresponse:(ljava/lang/string;iljava/lang/string;ij)v androidruntime      java.lang.unsatisfiedlinkerror: native method not found: org.cocos2dx.simplegame.simplegame.cppandroidapiresponse:(ljava/lang/string;iljava/lang/string;ij)v

here relevant java code:

package org.cocos2dx.simplegame;  private static native void cppandroidapiresponse(string token, int response, string data, int datalen, long context);  static {     system.loadlibrary("sb"); }  public static void callcppapiresponse (string result, string token, long context) { //this error triggered     cppandroidapiresponse(token, 200, result, result.length(), context); }

and in c++ file cppside.h:

# if (cc_target_platform == cc_platform_android) #include "platform/android/jni/jnihelper.h" #include <jni.h> #endif  #ifdef __cplusplus extern "c" { #endif # if (cc_target_platform == cc_platform_android) jniexport static void jnicall  java_org_cocos2dx_simplegame_simplegame_cppandroidapiresponse(jnienv *, jobject, jstring, jint, jstring, jint, jlong); #endif #ifdef __cplusplus } #endif

then cppside.cpp file

#include "cppside.h"  extern "c" { jniexport static void jnicall       java_org_cocos2dx_simplegame_simplegame_cppandroidapiresponse(jnienv *env, jobject obj, jstring token, jint response, jstring data, jint length, jlong context) { ...do stuff...} }

i know shared library loading because c++ based loading screen, , know jni working @ least partially because able call java same cppside.cpp file in method. have been researching jni , cocos2d-x documentation, no avail.

thanks in advance!

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
