Android: AIDL refusing to generate code from aidl file defining parcelable

I am trying to build a library with aidls. 

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := test

LOCAL_SRC_FILES := $(call all-java-files-under, java) \
java/com/testapp/Istudent.aidl \
java/com/testapp/Itest.aidl \

LOCAL_PREBUILT_JAVA_LIBRARY := framework.jar
include $(BUILD_JAVA_LIBRARY)

I am trying to refer the Istudent in Itest.

Istudent.aidl

package com.testapp;

parcelable Istudent;

Istudent.java

public class Istudent implements Parcelable{}

Itest.aidl

package com.testapp;

import  com.testapp.Istudent;

interface IAP2InterfaceBase {}

But error I receive is E 07-11 20:05:37 71066 71066 aidl.cpp:580] refusing to generate code from aidl file defining parcelable

Kindly let me know what we mean by "refusing to generate code from aidl file defining parcelable" ? And what wrong I am doing here..

Reason for Error can be understood as per below source code of aidl:

https://github.com/debian-pkg-android-tools/android-platform-system-tools-aidl/blob/master/aidl.cpp Line:536

if (!interface) {
    LOG(ERROR) << "refusing to generate code from aidl file defining "
                  "parcelable";
    return AidlError::FOUND_PARCELABLE;
  }

Also the aidl file that declares your parcelable class is not supposed to be included in build as mentioned on https://developer.android.com/guide/components/aidl.html under 'Passing Objects over IPC'. Below snippet copied from the website.

Finally, create an .aidl file that declares your parcelable class (as shown for the Rect.aidl file, below). If you are using a custom build process, do not add the .aidl file to your build. Similar to a header file in the C language, this .aidl file isn't compiled.

Don't know whether you have resolved this issue. I encountered the same problem, resolved it by downgrade Android SDK build tool to an earlier version, the build tool versions below 24 should be working, I used version 23.0.3

I encountered the same issue with you. The $(call all-java-files-under, java) command will find all aidl files whose name start with "I" (I*.aidl), but the parcelable class should not be included. Two solutions:

(1) Change the parcelable class name, do not start with "I":

parcelable Student;

(2) Move Istudent.aidl from LOCAL_SRC_FILES to LOCAL_AIDL_INCLUDES

LOCAL_SRC_FILES := $(call all-java-files-under, java) \
    java/com/testapp/Itest.aidl

LOCAL_AIDL_INCLUDES := java/com/testapp/Istudent.aidl

In your android.mk file replace 

LOCAL_SRC_FILES := $(call all-java-files-under, java) \
    java/com/testapp/Istudent.aidl \
    java/com/testapp/Itest.aidl \

with-----------

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