How to make a widget that doesn't drain the battery and updates often

Neither do I, but it seems "everyone" is taking this approach. I
really really miss guidelines on Android development. Both GUI design
guidelines (toolbars at the bottom anyone?) and design guidelines for
widgets doing more advanced things than updating a clock. It must be
100 different toolbars out there at the moment in various sizes. Why
can't we have a proper toolbar in Android? Sorry, off-topic :-)


I would love to see some better suggestions :-)

No wake-locks. Only using the following code to make the widget change
headline:
...
am.set(AlarmManager.RTC,  System.currentTimeMillis() + 5000,
pendingIntent);
...

According to the documentation this should work just brilliant. But my
phone is dead every morning with my widget running. Uninstalled!


Well, people will blame my widget even if I try to tell them that they
have another application that has wake_locks so I must make my widget
behave nicely with the rest of the apps out there.

Well I have made a new service that runs all the time and receives
broadcast events for screen off and on and that works great, so maybe
I'll stick with this. When I have started 10 of my favourite apps I
have a lot of services running so I guess people are used to this.
Seems like services is a bit overused these days so no wonder everyone
complains about battery life with Android...

1. Possible to deserialize java object on Android?

Hi there.

I was looking for information as to whether this is possible or not before I
go down this avenue
of writing sockets.

Essentially, I create a TCP/IP socket connection to a simple server I have
written in
Java that accepts socket connections (Using ServerSocket accept method). On
the android
side, I will want to serialize an object that of a class 'Foo' that
implements 'Serializable' interface.
The server will demarshall this object, make a modification, serialize it
again and send it back
to the android client over the same socket connection. My question is - Will
the android client
be able to demarshall the object? The reason I ask is that someone informed
me that android
does not use the java virtual machine and so and isn't byte-code compatible
at all.

Is HTTP REST a better option for communication between my android client and
server?

Many thanks for your help,
Best Regards
