Android Studio, aidl refusing to generate code from aidl file defining parcelable. Why?

Test.java (Implements Parcelable):

package com.app.pack.classes;

public class Test implements Parcelable {

private int test = 33;

protected Test(Parcel in) {
test = in.readInt();
}

@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(test);
}

@Override
public int describeContents() {
return 0;
}

public static final Creator<Test> CREATOR = new Creator<Test>() {
@Override
public Test createFromParcel(Parcel in) {
return new Test(in);
}

@Override
public Test[] newArray(int size) {
return new Test[size];
}
};
}

Test.aidl (Declares the class I want to send):

package com.app.pack.aidl;
parcelable Test;

TestService.aidl (provides the method that returns a Test object):

package com.app.pack.aidl;
import com.app.pack.aidl.Test;

interface TestService{
Test getAll(in int[] listOfInts);
}

这样写编译会报错：
refusing to generate code from aidl file defining parcelable couldn’t find import for class xxxxx

原因：
Test类的包名称，Test.aidl中的com.app.pack.aidl与Java代码中的com.app.pack.classes之间存在不匹配（不一样）; 他们需要匹配（完全一样）。
