Hello
I have a Problem when I tried to use AIDL interface with Lists.
I have 2 AIDL interfaces and I have to use a list with references to
the other AIDL interface instances.
Eclipse generates Java file which contains error.
I use android 1.6 and eclipse here is the my source code
MyDataAIDL.aidl
import de.koch.aidl.EntityAIDL;
interface MyDataAIDL {
void combineFromEntityList(in List<EntityAIDL> aEntityList);
List<EntityAIDL> getEntitys();
}
EntityAIDL.aidl
package de.koch.aidl;
import android.os.IBinder;
interface EntityAIDL{
void setName(String aName);
String getName();
}
Eclipse tells no error in aidl files and generates the classes.
but the generated class contains an error because
de.koch.aidl.EntityAIDL is not from type IBinder.
case TRANSACTION_readDB:
{
data.enforceInterface(DESCRIPTOR);
java.util.List<de.koch.aidl.EntityAIDL> _result = this.readDB();
reply.writeNoException();
reply.writeBinderList(_result);//Here is the Problem
return true;
}
This is clear to me because only the generated Stub is from Typ
IBinder.
But how should I change the AIDL file to get the correct generated
Java File.
Hope you could help.
