Android 没有aidl的远程服务？

Question

Is it possible to write Remote Service in Android without aidl? If yes - is it better to use then aidl?

Answer 1

No. If you want to write a remote service, you will -- at some level -- be using code very similar to AIDL. While AIDL is used for generating the stubs and packaging data, you can also use a Messenger and Handler pair: but this is simply implemented on top of AIDL, so you're using it anyway. For simple exchanges, a Messenger and Handler pair works, but for more complex situations using AIDL is appropriate. If your question is whether there is a lighter communication mechanism (other than just Intents) than AIDL, the answer is no.
