从本机代码访问生成的Android R类(Access generated Android R class from native code)

从本机代码访问生成的Android R类(Access generated Android R class from native code)

我想知道是否有一种方法可以从本机代码访问R类属性，我需要它来读取一些生成的ID，这些ID可能会在我每次执行项目的干净构建时发生变化，我宁愿不将它们手动传递给原生部分。

编辑正如@trashkalmar建议的那样解决方案：

static const char* const strClassName = "your/app/package/R$string"; clazz = env->FindClass(strClassName); if (clazz == NULL) { LOGE("Can't find class %s\n", strClassName); return result; } jfieldID field = env->GetStaticFieldID(clazz , "you_string_resource", "I"); jint value = env->GetStaticIntField(clazz, field);

I'm wondering if there is a way to access R class attribute from native code, I need it to read some generated ID that may change every time i do a clean build of my project and I would prefer not to pass them manually to the native part.

EDIT As suggested from @trashkalmar here is the solution:

static const char* const strClassName = "your/app/package/R$string"; clazz = env->FindClass(strClassName); if (clazz == NULL) { LOGE("Can't find class %s\n", strClassName); return result; } jfieldID field = env->GetStaticFieldID(clazz , "you_string_resource", "I"); jint value = env->GetStaticIntField(clazz, field);

最满意答案

访问您的R类并像其他任何类一样读取其字段。

Access your R class and read its fields as any other classes.
