Android的AIDL编译错误：无法找到类进口 [英] Android Aidl Compile Error: couldn't find import for class

问题描述

（我知道有即将加入parcelable为的NetworkInfo计算器上和其他地方的多个问题（如谷歌组），但这并不是这个。的）

我的工作是在$（AOSP_ROOT）/设备/并且涉及多个 AIDL 文件。它的一个很喜欢，

My work is under $(AOSP_ROOT)/device/ and involves multiple aidl files. one of it is like,

package com.example;

parcelable SomeRequest;

和其他AIDL是喜欢，

And another aidl is like,

package com.example;

import com.example.SomeRequest;
interface SomeService {
    SomeRequest getRequest();
}

和我会像编译错误，

device/somedevice/sdk/libs/aidl/com/example/SomeService.aidl:9: couldn't find import for class com.example.SomeRequest

我不知道这是处理AIDL文件的顺序。我Android.mk样子，

I'm wondering it is the order of processing aidl files. My Android.mk looks like,

LOCAL_SRC_FILES := $(call all-java-files-under, src) $(call all-Iaidl-files-under, aidl)
LOCAL_AIDL_INCLUDES := $(call all-Iaidl-files-under, aidl)

后，我从SRC /文件夹移动AIDL文件AIDL /文件夹（出于某种原因，我必须这样做）引入此版本错误。即使我把它回的src /文件夹，它不工作了它的工作之前，但现在。我试图清理$（AOSP_ROOT）/输出/设备/目标，但它没有帮助。

This build error is introduced after I moved aidl files from src/ folder to aidl/ folder (for some reason I have to do so). It worked before but now even if I moved it back to src/ folder it doesn't work anymore. I tried to clean up $(AOSP_ROOT)/out/device/target but it's not helping.

想法？

推荐答案

最后我得到了解决。

如果你深入研究 /build/core/base_rules.mk ，你会发现， LOCAL_AIDL_INCLUDES 实际上是期间AIDL除了状框架左右默认文件夹编译阶段被包括在文件夹。

If you dig into /build/core/base_rules.mk, you'll find that LOCAL_AIDL_INCLUDES is actually the folders to be included during AIDL compiling phase in addition to the default folders like framework or so.

$(aidl_java_sources): PRIVATE_AIDL_FLAGS := -b $(addprefix -p,$(aidl_preprocess_import)) -I$(LOCAL_PATH) -I$(LOCAL_PATH)/src $(addprefix -I,$(LOCAL_AIDL_INCLUDES))

在这种特殊情况下，你想要的其实是，

In this specific case, what you want is actually,

LOCAL_SRC_FILES := $(call all-java-files-under, src) $(call all-Iaidl-files-under, aidl)
LOCAL_AIDL_INCLUDES := $(LOCAL_PATH)/aidl
