关于emjoy表情在android5.x以上系统触发jni错误的修改(基于cocos2dx2.1.5修改)

 bool getBitmapFromJavaShadowStroke(	const char *text,int nWidth,int nHeight,CCImage::ETextAlign eAlignMask,const char * pFontName,float fontSize,float textTintR 		= 1.0,float textTintG 		= 1.0,float textTintB 		= 1.0,bool shadow 			= false,float shadowDeltaX 		= 0.0,float shadowDeltaY 		= 0.0,float shadowBlur 		= 0.0,float shadowIntensity 	= 0.0,bool stroke 			= false,float strokeColorR 		= 0.0,float strokeColorG 		= 0.0,float strokeColorB 		= 0.0,float strokeSize 		= 0.0 ){JniMethodInfo methodInfo;if (!

同时java对应修改传入参数

在Cocos2dxBitmap.java中,createTextBitmapShadowStroke传入参数修改为byte[]类型,然后将byte[]转化为string来正常直接emjoy的输出
