    <p>To avoid useless answer about how to implement AIDL in your own project - I understand how to use AIDL in your own project. </p> <p>What's unclear for me is how it is used in Android source code? </p> <p>For example, there is IAudioService AIDL interface in android.media package. And there is AudioService java file. And there are a lot of examples where interface is defined in IInterfaceServiceName.aidl and implementation is in InterfaceServiceName.java. So, I thought that internals of AIDL look for Service with the name without first capital I, and then use it. However, this theory was demolished by IWifiManager and WifiService. </p> <p>All of this AIDL implementations, however, share one thing - they all extend IInterfaceName.Stub class. So, that means AIDL internals look for classes extending IInterfaceName.Stub? But what if there are multiple classes extending it? And those classes aren't services at all...</p> <p>Or there is some Service Manager, which somehow creates Services with those AIDL implementations as Binders? If so, please direct me to this mysterious service manager.</p> <p>EDIT: I've found this service manager. It is ServiceManager in package android.os. Now it's understandable why those SomethingService aren't actually services but are actually IBinders - the service manager somehow creates services with given IBinder by method add service(String, IBinder). But now confusion only becomes even worse. The implementation of this service also lies in somewhat strange ServiceManagerNative, which involves remote transaction with unknown IBinder. Now I'm totally lost. How then does this ServiceManager starts itself up? How are the services added by it? </p>

    2. COYou didn't read the question first sentence, did you? I am NOT interested how to implement AIDL in my app - I know how to do it. Instead, I am trying to understand how exactly Android system services and AIDL like IWifiManager are being connected.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
