Risk of upgrading to 1.1?

 I was going to keep my SDK at 1.0 because for my own app I don't need
any 1.1 stuff and I'd like it to work on as many devices as possible.
If I upgrade my dev-phone to 1.1 just because I'd like a nicer phone,
is there any appreciable risk that it will fail to detect problems
that might occur on 1.0 devices?  -Tim


Risk of upgrading to 1.1?

 I have released my game on 19th of February, built against SDK 1.1 but
no minSdkVersion, and tested on my G1 w/ 1.1, i.e. it should be
working on 1.0 devices. So far I haven't got a report that it's not
working on any device, other than the intermittent "Force Close"
issues after an update.

Bottom line is, don't worry, install 1.1 and build against SDK 1.1 - I
haven't had any problems. Surely I haven't used any feature from 1.1,
not that there are many.

Risk of upgrading to 1.1?

 Well, there is a risk that a bug in 1.0 that would have been fixed in
1.1 could be hit by your application. I'm not explicitly aware of such
situations, but that's definitely possible in theory.

It is possible (and in fact reasonably easy) to downgrade an ADP1 back
to 1.0, the drawback being that you need to wipe your data in that

A very valid situation. But does it matter? All Android devices have
the posibility to run 1.1, so if you build for 1.1, why not set
minSdkVersion? You only are making your app more secure, and you are
not excluding anyone (except for some developer still running 1.0 for
some very specific reason).

And if you are still on 1.0, I think upgrading always is the better
option, because all devices support it and 1.1 will have less bugs, or
at least less bugs in code which was available in 1.0. Though staying
with 1.0 won't really have any negative results.

1. How to manage Delay in InputStream ?


I do a POST on a URL on the web.  I get back an InputStream.

Even using a regular web browser this response comes back with a delay
(2-5 sec).

In Java, when I finished my post, close OutputStream , and read the
response, as nothing as arrived yet : I get nothing and my app thinks
the InputStream is finished, and I exit my method.

How can I wait for something to come from an InputStream ?

There's a support issue running at

I'd urge UK developers to post their comments so that this can be raised 
up on Googles radar.
