一直糾結著這個錯誤,後來看別人的文章找到靈感,於是完善了基於cocos2dx2.1.5修改的

具體報錯:JNI DETECTED ERROR IN APPLICATION: input is not valid Modified UTF-8: illegal continuation byte 0xed

解決辦法(基於coocs2dx2.1.5):

在CCImage.cpp裡面的getBitmapFromJavaShadowStroke方法中,emjoy表情在jstring jstrText = methodInfo.env->NewStringUTF(text);

的時候觸發崩潰,原因大致估計是因為emjoy不能被utf識別,於是繞過NewStringUTF,將之轉化為byte[]來繞過.具體遮蔽jstring jstrText = methodInfo.env->NewStringUTF(text);修改為

 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 )

同時java對應修改傳入引數

在Cocos2dxBitmap.java中,createTextBitmapShadowStroke傳入引數修改為byte[]型別,然後將byte[]轉化為string來正常直接emjoy的輸出
