dalvik中Java類庫有許多本地類(全本地方法)

當(Java/C++)調用(Java類庫中)本地類的本地方法時,ResolveNativeMethod:查映射表-->本地類的本地函數集-->本地函數指針

?

類庫的本地函數集

};

具體的本地類(java.lang.Class)的本地函數集

const DalvikNativeMethod dvm_java_lang_Class[] = {
??? { "classForName",?????? "(Ljava/lang/String;ZLjava/lang/ClassLoader;)Ljava/lang/Class;",
??????? Dalvik_java_lang_Class_classForName },
??? { "getClassLoader",???? "(Ljava/lang/Class;)Ljava/lang/ClassLoader;",
??????? Dalvik_java_lang_Class_getClassLoader },
??? ......,
};
