Android: transfer byte array with AIDL
aidl, android
Solution
Try using byte[] instead of List, it works for me.
interface IMyService {
int putBytes(String key, in byte[] bytes);
int getBytes(String key, out byte[] bytes);
}
AIDL only support primitives, String, CharSequence, List, Map. You can have List but never List

Problem
I need to transfer byte array between an Android service and client. I have tried to define an aidl interface like: ``` interface IMyService { int putBytes(String key, in List<Byte> bytes); int getBytes(String key, out List<Byte> bytes); } ``` But, it doesn't compile. The error is: ``` [aidl] E:\workspace\RAMService\src\com\connexis\service\mem\IRAMService.aid l:14 parameter bytes (2) unknown type List<Byte> ``` Could someone help me? Thanks in advance!
