How to return MyObject list in android help file?

Question

I have this method in a .aidl file:

void getObjects(out List<MyObject> objList);

But I get this error

src / com / mycompany / mypackage / ITestService.aidl: 26 parameter objList (1) unknown type List objList

How to create a MyObject list in .aidl?

Thanks.

Answer 1

Steps:

• MyObject implements Parcable

• Create a new MyObject.aidl file at src.com.mycompany.mypackage

    package src.com.mycompany.mypackage;
    parcelable MyObject;
  

  Reason: you transfer class objects between processes, the client process must understand the definition of the transferred object.

  AIDL complier will not be able to find our self-defined MyObject, even if it implements the Parcelable interface. To report our implementation to the AIDL compiler, we need to define a helpl file that declares the Parcelable class

• ITestService.aidl ,

  import src.com.mycompany.mypackage.MyObject

Answer 2

MyObject Parcelable, MyObject AIDL.
