    <p>So I've written a Service and an Activity for the Android OS.</p> <p>My service is running in it's own process, so all the communication between my Activities and the Service happens via IPC. I use the standard Android .aidl mechanism for this. </p> <p>So far everything works fine. However, the AIDL generates all method stubs using "throws RemoteException" so I have to handle them. </p> <p>I did a quick grep on the entire Android source-code and only found three cases where this exception is ever thrown. These are in a different service that I don't connect with.</p> <p>I checked the C-sources as well because in theory RemoteExceptions can be generated using the JNI interface.. Nothing turned up.</p> <p>I have the impression that everyone just handles them like this:</p> <pre><code> try { mService.someMethodCall (someArguments); } catch (RemoteException e) { e.printStackTrace(); } </code></pre> <p>This is not solid code, and I don't want something like this in my code-base. </p> <p>Besides that: I tried to throw a RemoteException via IPC myself and all I got was a stack-trace and a system log message that tells me that exceptions aren't supported yet. My application never saw the exception and the services that threw the exception ended up in a very strange state (halfway working) :-(</p> <p>The questions are:</p> <ul> <li><p>Do these exceptions ever get thrown? </p></li> <li><p>Has anyone ever seen such a try-catch block catching a RemoteException?</p></li> <li><p>Could it be that they don't exist and that we are just forced to deal with them because the "throws RemoteException" is dead code or a left-over inside the AIDL compiler?</p></li> </ul> <p>Disclamer: I haven't read the entire source-code. I used Grep to find the occurrences of RemoteException, so I may have missed some due to different whitespace usage. </p>

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.
