0.eclipse上编写C++

stringHelloWorld::init() {} //无return程序会崩溃

1.文件

CCFileUtils::sharedFileUtils()->fullPathFromRelativePath("")

CCFileUtils::sharedFileUtils()-> getWritablePath("")

fullPathFromRelativePath android上是读 assets

getWritablePath android上是 /data/data/包名/

 

可能是大多程序的路径

Environment.getExternalStorageDirectory() + "/Android/data/" + pApplicationInfo.packageName + "/files/" + pPath;

 

2.JNI

java返回String类型给C++

 JniMethodInfo minfo

 JniMethodInfo minfo.env  //env 是JNIEnV 

 (Ljava/lang/String;)Ljava/lang/String;

返回jstring类型必须用jobject obj接受否则不能编译通过

再把jobject转换成jstring jRet = (jstring) obj;

const char* msg3 = (minfo.env)->GetStringUTFChars(jRet, NULL); //jstring转换const char*
