android studio aidl couldn't find import for class

By default, AIDL supports the following data types:

• All primitive types in the Java programming language (such as int, long,char, boolean, and so on)
• String
• CharSequence
• List

  All elements in the List must be one of the supported data types in this list or one of the other AIDL-generated interfaces or parcelables you've declared. A List may optionally be used as a "generic" class (for example,List<String>). The actual concrete class that the other side receives is always an ArrayList, although the method is generated to use the List interface.

• Map

  All elements in the Map must be one of the supported data types in this list or one of the other AIDL-generated interfaces or parcelables you've declared.  Generic maps, (such as those of the formMap<String,Integer> are not supported. The actual concrete class that the other side receives is always a HashMap, although the method is generated to use the Map interface.

You must include an import statement for each additional type not listed above, even if they are defined in the same package as your interface.

如果不是AIDL数据类型，需要自己定义一个新的AIDL文件并实现parcelable接口，示例如下：

 

For example, here is a Rect.aidl file to create a Rect class that's parcelable:

package android.graphics;

// Declare Rect so AIDL can find it and knows that it implements
// the parcelable protocol.
parcelable Rect;

And here is an example of how the Rect class implements theParcelable protocol.

import android.os.Parcel;
import android.os.Parcelable;

public final class Rect implements Parcelable {

实体类的aidl应该在实体类所在的包名下
