Mark,
Well, the manifest documentation is pretty sparse so it's not
surprising that it doesn't mention this case. A good example is the
screen of choices that face you when you look at the Application tab
in the manifest editor in Eclipse and click on one of the activities
or services. That calls up a form with about 25 choices, none of which
include an action, by the way. A document that describes what all
these choices mean would be very helpful. Note that there's a choice
called clear task on launch, a phrase that you can search in vain
for in the manifest documentation.
It seems like people mostly build projects by copy-paste from other
projects, which is a fine approach as far as it goes but it can grow
into a nightmare if people start propagating unsupported hacks. Then
you have hundreds of apps that break at the same time when a new
release invalidates the hack.
OK, down off my soapbox. The change you suggest below didn't work.
Same exception in logcat. I can think of several approaches to take it
from here:
1) I build a simple test project that illustrates the problem and
submit it as a bug.
2) We decide that this approach is unsupported, in which case I submit
a bug against the documentation.
3) We take another swing at it, recognizing that we are implementing
something that lives on shaky ground, since undocumented behavior can
change at any time.
What do you think?

Regardless, I see where I went wrong before.
Your error is:

Notice the act=com.shipmate.AboutShipMateActivity part. That says
the Intent it is trying to use has an *action* of
com.shipmate.AboutShipMateActivity. So, add anintent-filter with an
action of com.shipmate.AboutShipMateActivity to your activity, and
you should have better luck.

Well, your source code got cut off, so it is difficult to answer. Somewhere, your Activity is calling setContentView(). Ideally, particularly for this case, setContentView() is passed a resource ID pointing to a layout resource (e.g., R.layout.main). This is the layout file that Nick demonstrated and Kostya referred to. That layout for your whole activity needs to have your Button and your ListView, wrapped in a RelativeLayout or LinearLayout. Here is an example project, albeit one with a TextView instead of a Button above the ListView: http://github.com/commonsguy/cw-android/tree/master/Selection/List/ Here is a variation on that sample project, using a custom ListAdapter: http://github.com/commonsguy/cw-android/tree/master/FancyLists/Recycling/ -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy _Android Programming Tutorials_ Version 2.9 Available! -- You received this message because you are subscribed to the Google Groups Android Beginners group.

I can't find where what you're doing is documented, so I have no idea
what the right behavior is. Do you have a link to where it describes
this intent child element of Preference?
Regardless, I see where I went wrong before.
Your error is:
E/AndroidRuntime( 376): android.content.ActivityNotFoundException: No
Activity
found to handle Intent { act=com.shipmate.AboutShipMateActivity }
Notice the act=com.shipmate.AboutShipMateActivity part. That says
the Intent it is trying to use has an *action* of
com.shipmate.AboutShipMateActivity. So, add an intent-filter with an
action of com.shipmate.AboutShipMateActivity to your activity, and
you should have better luck.

the map remains centered on Kansas, which I think is the default.
I got the geo locations for testing purposes by going to
maps.google.com and entering San Francisco, then generating a string
intended for emailing, then picking the lat/lon values from that
string. As far as I know, the GeoPoint passed to setCenter is just
those values multiplied by 1e6.
Any ideas why it's not working?

On Sat, Jul 3, 2010 at 7:42 PM, Indicator Veritatis mej1...@yahoo.com wrote: That may be true, but if so, there is a serious problem with the online Android documentation. For as I have already shown, the documentation clearly states that there is a possible transition direct from the started state to the stopped state, one that does not call onPause() first. That would occur in fairly rare cases, when something occurs on the device after onStart() and before onResume(). Since those methods are invoked in rapid succession, something else taking over the screen (e.g., phone call comes in) during that window is rather unlikely. Developers should not be worrying about that particular scenario very much, if at all. So other than your own authority, on what grounds do you say that the docs are wrong? The docs are not wrong. However, my previous post was covering the 99.999% case, not every possible scenario. On Sat, Jul 3, 2010 at 7:50 PM, Indicator Veritatis mej1...@yahoo.com wrote: This is certainly wrong.

I even had to run my own test, just to confirm I hadn't slid into some parallel dimension, before writing my previous post. onDestroy() is called after the BACK button is pressed, just like it is supposed to.

On Sun, Jul 4, 2010 at 7:21 PM, Indicator Veritatis mej1...@yahoo.com wrote: Do you really want to encourage, for example, Android programmers to fail to handle correctly the case where onStop() is called without a preceding, corresponding call to onPause()? Such programming sounds very careless to me. Generally, I'd recommend the implementations be independent. Wherever possible, onStop() should not care whether or not onPause() preceded it, even though most of the time, it will. That's pretty basic state machine design. Even if most of the time (even your 99.999% is an overstatement), the programmer can ignore this scenario, he should be aware that it exists, so then when he needs to take care of it, he knows that he needs to do so. I'm not arguing that it'd be nice if the docs explained the circumstances of all of these corner cases better. Similarly with the second issue: even Google violates the rule [that onBackPressed() should cause onDestroy() to be called] often enough that your readers are going to be confused if they forget that some apps really do override onBackPressed(), they don't all call onDestroy(). I am sincerely hoping that somebody who overrides onBackPressed() will notice that their fingers typed those keystrokes and will therefore consider that, gee, maybe onBackPressed() might have something to do with what happens when BACK is pressed. I am not aware of any supplied Activity implementation (e.g., ListActivity) that overrides onBackPressed(), so such behavior will not be hidden too often. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy Android Consulting: http://commonsware.com/consulting -- You received this message because you are subscribed to the Google Groups Android Beginners group.

Re: [android-beginners] back button when in ListActivity causes runtime exception

Try replacing cb.getContext() with this.

That is not an exception. It is a stack trace. You are missing the
exception part, and the Caused by: portion.

Re: [android-beginners] Re: Unable to start service
On Fri, Jul 2, 2010 at 1:02 PM, Bret Foreman bret.fore...@gmail.com wrote:
Intent.setClass needs a Context for the first argument. Replacing
cb.getContext with this causes a compiler error. Do you mean I
should call getApplicationContext?
No, I mean you should use the proper value of this.
Your code is:
try {
Intent myIntent
= new Intent();
myIntent.setClass(cb.getContext(), SensorService.class);
startService( myIntent );
} catch( Exception e ){
android.util.Log.e( getString(R.string.app_name) , Unable to
start sensor service , e );
}
Do you see your call to startService()? That is a method on Context.
Whatever object you are in, it is a Context. If this gives you a
compiler error, yet startService() does not, that means this code
snippet comes from an inner class, and so you need to scope your
this to the proper outer class (e.g., MyActivity.this).
Here's the full trace:
Perhaps Eclipse considers that to be a trace. It is useless to me and,
presumably, to you.
If you continue execution past this point, your exception, with a full
exception message and two-tier stack trace, will be written to logcat.
This will be accessible from Eclipse via the DDMS perspective, in the
LogCat tab, in red.
