[android-developers] IllegalStateException: No wrapped connection.
Hi,
I'm trying to send an HTTP request from a WakefulService so a Service which has
been started from an alarm set up with AlarmManager and I get the error:
IllegalStateException: No wrapped connection.
HttpGet httpGet = (HttpGet) new
HttpGet(MYRequestHelper.getRequest(this));
HttpClient client = ((MYApplication) getApplication()).getHttpClient();
String response;
try {
response = client.execute(httpGet, new BasicResponseHandler());
At this point I run through parsing JSON and creating new HttpGets and
executing them on the client.
Is it possible I running execute too many times on the client or something?
I'm don't really understand what the error means and I haven't been able to
glean anything much from Googling other than to catch it and hope for the best.
Cheers,
Julius.

You might want to read the documentation for BroadcastReceiver, understand the different between normal and ordered broadcasts, and find out which one the third party is generating. My guess is that it's generating an ordered broadcast and sometimes its own receiver is catching it first and aborting it. I don't think it's a good idea to re-broadcast normal broadcasts, because I imagine your receiver and any others could get called more than once (or even infinitely?!) if you're not careful. And I don't think it's possible to force yourself to receive an ordered broadcast if it was aborted upstream.

Re: [android-developers] IllegalStateException: No wrapped connection.
There is something messed up with your HttpClient object. That
exception is being raised by HttpClient itself, based upon what I can
see in the Android source code.
Bear in mind that, in the case of an alarm, your process hopefully was
terminated/recycled since the last alarm, and so there is little value
in attempting to reuse some global HttpClient here. I'd just create a
new one.
Also, bear in mind that all IntentServices do their work on a
background thread, and HttpClient is not thread-safe by default. It's
possible this error is tied to that. You need to hook up a
ThreadSafeClientConnManager to the HttpClient object if you will reuse
it across multiple threads.

Mostly, I just want to differentiate the Intents enough that they are not considered duplicates. Any pointers would be appreciated. I believe that Android uses filterEquals() on Intent to determine if two Intents are equivalent for this purpose. From the documentation: Determine if two intents are the same for the purposes of intent resolution (filtering). That is, if their action, data, type, class, and categories are the same. This does not compare any extra data included in the intents. To be fair, the javadoc for Intent.filterEquals() says nothing about if or when a broadcast intent would be dropped for any reason. Or do you think it's implied? It's strange because I just authored an IntentService yesterday that does work on command, then broadcasts an intent with an action and a single extra which varies based on the work done.

[android-developers] One process, two live Application objects?
In a comment on an epic StackOverflow question-and-answer, a gentleman who I will call Tim has outlined a scenario he says he is running into, one I have some difficulty believing. Reading somewhat between the lines, the flow would appear to be this: 1. User taps on an activity icon in the launcher 2. Process starts up 3. Application object is put in that process -- and a custom Application object loads an NDK library which initializes some statics/singletons 4. User uses application 5. User abandons application (e.g., HOME) 6. Later, user returns to application, before the first process is killed or recycled for use with another app 7. A second Application object is created, in the same process, before the first Application object is called with onTerminate() This screws things up for Tim's app -- apparently, it does not deal with pre-initialized statics/singletons well.

Re: [android-developers] One process, two live Application objects?
Well, in Tim's case, that static block would only be fired once, presumably.
If Application instance B is created before Application instance A is
terminated, then we're still talking the same VM, and so the static
initializer would have been run when A was created and would not be
re-run when B is created.
I suppose the real problem might be that A is *never* being
terminated, despite the process being recycled, though I haven't seen
any signs of that occurring, either. This might occur if Android is
recycling the process but not the VM, for example.
I suspect that Tim can work around his problem via passing the
Application object to his NDK library and detecting a change in that
object (e.g., different hashCode()), reinitializing his statics when
that occurs.

Re: [android-developers] One process, two live Application objects?
Right, a static block runs only once. And is guaranteed to run in this
case, since Android is going to instantiate MyApplication.
You wrote in the original email that the native side needs to initialize
some statics and singletons. Those should only be initialized once, so a
static block works here.
As for terminating those singletons - presumably, they can be left
around until Android kills and cleans up the entire process.

[android-developers] How can I create an aircraft-mounted-liked compass?
I want to create a non-generic compass that uses rotating directions instead of a rotating needle as in the conventional compass. The drawing is like the illustration below. | ' ' W ' ' ' ' ' N ' ' ' ' ' E ' ' ' ' ' S ' ' ' (shift a bit to the east) | ' ' ' ' ' N ' ' ' ' ' E ' ' ' ' ' S ' ' ' ' ' W The needle (depict as |) is fixed and the direction string should have some sort of rotation effect that immediately relocates each sign or character from one tip of the edge to the opposite edge. Of course, the movement follows the reading of the Android sensor. Does anyone has an idea how to implement this? I stumbled with how I create the rotation effect and connect the string's movement with the sensor reading.

Re: [android-developers] IllegalStateException: No wrapped connection.
Hi Mark,
Looks like it was a threading issue - from what you say; IntentService doing
work on a separate thread, so just creating a new DefaultHttpClient seems to
have done the trick.
Thank you for explaining (once again) :)

Julius.

[android-developers] Extending SimpleCursorAdapter
I'm an Android newbie, stuck on a problem for a over week now, if I knew what I was doing it would be 10 minutes work. Im using the NotePad example as a base for an application. This binds a ListActivity to a Provider. Its perfect, except it uses SimpleCursorAdaptor, which means the list only binds to and displays one item per row. I want it to display two items, both bound the Provider. Or more accurately display the text from one Content Provider field and an icon which depends on the value of a different field. This sounds like a pretty simple thing to do, a very slight modification to the NotePad application. Trouble is, I have no idea on *how* to do it. I really need a starting point, and approach to use. So far I have tried (unsuccessfully): * Hand populating the ListView by reading in the Provider data and populating an array in OnCreate. This works, except as the data is not bound the List does not update when I add an item. * Extending SimpleCursorAdapter with a custom getViewBinder. Could still only bind to a single column. * Building my own ListAdaptor. Couldn't get this to work. * Concatenating both fileds together and parsing 2 fields into 1 field read/write. The next thing I will try is extremely tacky running two separate simpleCursorAdaptors in two views in a Linear Layout, fudged so the row height is identical, and duplicate the logic. I say this only to show that I really, really have tried. Could someone give me at least a hint as to how I can create a custom CursorAdaptor which binds to two fields instead of just one like SimpleCursorAdapter? There must be some easy way Sorry/thanks/help Peter Webb -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] One process, two live Application objects?
On Sun, Oct 31, 2010 at 4:39 AM, Kostya Vasilyev kmans...@gmail.com wrote: Right, a static block runs only once. And is guaranteed to run in this case, since Android is going to instantiate MyApplication. You wrote in the original email that the native side needs to initialize some statics and singletons. Those should only be initialized once, so a static block works here. Apparently, Tim's app (combined with the scenario I outlined) does not deal well with this case. Near as I can interpret matters, his app gets confused when a new Application object is created yet his statics are still in the state from the previous Application object. Part of the problem is that his native code was written for iOS, which does not recycle processes. If the user plays this game, leaves the game, and comes back into the game, it's a brand new process with brand new initialized statics. Again, I think he can work around that by more closely tracking the Application object instances themselves. I'm just trying to figure out if the overlapping-Application condition can really happen. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy Android 2.2 Programming Books: http://commonsware.com/books -- You received this message because you are subscribed to the Google Groups Android Developers group.

Have you tried calling .invalidate to force a redraw between steps, so
the display and your code stay in sync?

You can call super.bindView() to allow SimpleCursorAdapter to do the basics, then use findViewById() on the row View to find your ImageView and set an appropriate resource on it.

Re: [android-developers] Extending SimpleCursorAdapter
Peter,
SimpleCursorAdapter is the simplified version of the CursorAdapter.
You need to use the real thing and override newView() and bindView().
newView needs to load (inflate) a new list item layout.
bindView needs to set values in views contained in the list item layout
to reflect values retrieved from its cursor.
The whole class might look something like this:
private static final class YourAdapter extends CursorAdapter {
YourAdapter(Context context, Cursor cursor) {
super(context, cursor);
mInflater = LayoutInflater.from(context);
mColField1 = cursor.getColumnIndex(name of db field 1);
mColField2 = cursor.getColumnIndex(name of db field 2);
}
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
View v = mInflater.inflate(R.layout.my_list_item, parent, false);
return v;
}
@Override
public void bindView(View view, Context context, Cursor cursor) {
// show text value
TextView tv = (TextView) view.findViewById(R.id.item_field_1);
tv.setText(cursor.getString(mColField1));
// show icon
ImageView iv = (ImageView) view.findViewById(R.id.item_field_2);
int icon_kind = cursor.getInt(mColField2);
iv.setImageResource(some resource id value based on icon_kind);
}
LayoutInflater mInflater;
private int mColField1;
private int mColField2;
}

[android-developers] How to get the selected Overlay index
hi guys,
i'm working with a google maps for a while now. i'm having multiple
markers in the map once you select a perticular maker an Overaly will
appear so once the Overlay is selected i want to get the index of the
overlay. every time its 0.
this is how i'm adding overlays
GeoPoint point = new GeoPoint((int) (postal_lat * 1E6),
(int) (postal_lng * 1E6));
Drawable postal_icon =
getResources().getDrawable(R.drawable.location);
MyItemizedOverlay itemizedOverlay2 = new
MyItemizedOverlay(postal_icon, mapview);
OverlayItem overlayItem_postal = new OverlayItem(point,
postal_msg, null);
itemizedOverlay2.addOverlay(overlayItem_postal);
MyItemizedOverlay implementation
public class MyItemizedOverlay extends
BalloonItemizedOverlayOverlayItem {
private ArrayListOverlayItem m_overlays = new
ArrayListOverlayItem();
private Context c;
public MyItemizedOverlay(Drawable defaultMarker, MapView mapView) {
super(boundCenter(defaultMarker), mapView);
c = mapView.getContext();
}
public void addOverlay(OverlayItem overlay, int id) {
m_overlays.add(overlay);
populate();
}
@Override
protected OverlayItem createItem(int i) {
return m_overlays.get(i);
}
@Override
public int size() {
return m_overlays.size();
}
@Override
protected boolean onBalloonTap(int index) {
NearestLocation near = MapInfo.nearestArray[index];
Toast.makeText(c, index + near.getPartname() + index,
Toast.LENGTH_LONG).show();
return true;
}
}
onBalloonTap always returns 0??

Mike

[android-developers] Intent resolution: supplying action+data where filter had only action, causes it to fail
I thought that Action was preeminent during intent resolution and if
the intent had the same action as the intent filter, it would be
considered a match regardless of data, if the filter did not specify
anything.
So I was very surprised to find that supplying action+data where
filter had only action, causes it to fail.
In the code below, if you comment out line 47 so that data is *not*
sent, only then it resolves correctly.
alertIntent.setData(alert_i);
To get it to work with the data (an id that is simply a String), what
mime type should I specify in the intent filter?
thanks...

[android-developers] Re: Adventures with LVL
If you have published an app including LVL, what are your experiences? 99.9% no problem. Has it caused bad feedback from your users? Once or twice, a long time ago. But my implementation is very forgiving. It doesn't care if the licence can't be verified for the first 7 days, and only needs one positive response (per install). It validates in the background so most people don't even notice it. I also have a backup licence-code system they can use if all else fails (I needed it for paypal sales).

Re: [android-developers] Re: Collecting my Market installation statistics
David, I'm in the process of developing a website that collects market statistics and developer statistics, and one of the features I'm adding is a utility to collect my own market download numbers daily so I can put them into a spreadsheet and chart/graph them so I can easily spot trends. I thought about adding this for use by any developer, but the problem with it is that to automatically collect the actual download numbers, we would have to store your Google login information, and I don't think many developers would want to give that information... I could be wrong, but that's my opinion. Maybe I should ask... How many developers would be willing to have a website (a trustworthy website) store their login information to be able to automatically collect the download/installed numbers so they could collect them? Without the login information the only way to get the actual download and installed numbers would be for the developer to visit a page and manually start the download information, and I'm not sure many developers would do that consistently enough to get good information. Let me know if you are interested in having this... I can add it fairly easily... but I'd need to know exactly what would be acceptable to the developers.

[android-developers] deprecating Display#getOrientation() not such a good idea
I'm not sure what the motivation was to deprecate Display#getOrientation() in SDK 8 is, since I haven't had a chance to read the changeset description. The decision made the API a little less humanistic. I propose it be brought back in SDK 9 for these reasons: 1) The community has two+ years of discovery and documentation around Display#getOrientation. 2) There's no clear reason why applications which don't distinguish between a 90/270 degree rotation should have to implement extra work for forwards/backwards compatibility. 3) The system already decides which side is top whether the rotation is 90 or 270 degrees. 4) android.view.Surface has no setRotation(...) method, it uses setOrientation(...). Thus, if Display#getOrientation() was to be deprecated, the same should have happened to Surface#getOrientation for architectural symmetry. 5) Using Display#getOrientation() will always be desired by some applications, whereas Display#getRotation() will always be desired by others. The frustrating factor here is that on top of the confusion caused by the SDK having different classes/methods to get runtime orientation versus configured orientation, this deprecation is poorly motivated.

a column of 7 graphics(_theGrid) and when I remove a graphic from it,

If I only add the first graphic, the graphic is drawn CORRECTLY to x63
y63
if I add both, the first is drawn INCORRECTLY to x0 y0, and the second
graphic is drawn CORRECTLY to x63 y126
if I add a third, the the first TWO are drawn INCORRECTLY and the last
is drawn correctly.
I have tried invalidate and postInvalidate with no success and have
hit a wall.
Can anyone here help me remedy this problem, I am totally stumped
here :?

Re: [android-developers] One process, two live Application objects?
Only one Application per-.apk-per-process is created, ever. If you use android:process to have multiple .apks sharing the same process, each .apk will have its own Application instantiated in the process. If you use android:process to have an .apk run in multiple processes, each process will get its own Application instance. Application.onTerminate() is *never* called. This function is there for environments where processes are emulated, which is not any production device or the emulator. But it doesn't matter that it isn't called because... well, Application lives for the lifetime of the process, and the process goes away by the OOM killer killing it, which cleans up Application and everything else related to the process without any user space code for it running. Now it is conceivable that there is some case where if a process is left completely empty (with no app components) for a while, and GCs, the data about the loaded process may get GCed as well and have to be recreated. I don't see how this can happen off-hand (there are a number of ways non-weak-references are held between these things), but I can't say for certain there is no such bug here. That said, my recommendation to everyone is to just not subclass Application. This gives you *nothing* you can't do in other, better ways. In particular, a singleton directly represents what is really going on (it lives for the life of the process after the first need for it) and helps keep code more modular. I regret that the Application class was ever introduced; it was a compromise to make people more comfortable with there being some kind of traditional main application concept, but in fact it doesn't really fit in with how Android works so ends up just causing problems. As far as using Application to clean up statics -- this simply doesn't really make sense, for the reasons above. For a legacy application with statics that can't be re-used again in the same process, your only choice is probably to just self-kill your process when the user leave the game. That is, when the game activity is finished. If you can reset your statics after the game is over, then at least instead of killing it you can do that when the activity is finished. But this needs to be driven by Activity, not Application.

Reading somewhat between the lines, the flow would appear to be this: 1. User taps on an activity icon in the launcher 2. Process starts up 3. Application object is put in that process -- and a custom Application object loads an NDK library which initializes some statics/singletons 4. User uses application 5. User abandons application (e.g., HOME) 6. Later, user returns to application, before the first process is killed or recycled for use with another app 7. A second Application object is created, in the same process, before the first Application object is called with onTerminate() This screws things up for Tim's app -- apparently, it does not deal with pre-initialized statics/singletons well. They were presumably counting on onTerminate() to let them clean up the NDK space. As a result, they are relying upon killProcess() (somehow...unclear under what conditions they might call this) to force their own process to go away, so their statics get cleaned up. Step #7 is what confuses me. I can see a new Application object being created, but only if the first Application object were terminated. I don't see any NDK-related bugs out on b.android.com that seem to match this complaint, though in principle it might cause problems for non-NDK apps as well.

Re: [android-developers] deprecating Display#getOrientation() not such a good idea
getOrientation() has never returned orientation, it returns rotation. So it is being renamed to getRotation(). This is *much* less confusing. In fact you were confused -- you thought it returned orientation, when it does not. If you want the current orientation, Resources.getConfiguration().orientation has that. Surface.setOrientation() is actually not available to applications (it is an accident it is in the SDK, but apps don't have permission to use it, so there is nothing they can actually do with it), so not really relevant here. The solution for that one is probably just to remove it from the SDK since apps can't use it anyway. This was done to better clarify the differences between orientations and screen rotations, which a lot of people have been confused about, and has resulted in a lot of incorrect use of sensors and such. It's worth noting that both Display.getOrientation() and Surface.setOrientation() work with the constants Surface.ROTATION_0, Surface.ROTATION_90, Surface.ROTATION_180, etc. Those APIs intrinsically have a naming conflict.

The decision made the API a little less humanistic. I propose it be brought back in SDK 9 for these reasons: 1) The community has two+ years of discovery and documentation around Display#getOrientation. 2) There's no clear reason why applications which don't distinguish between a 90/270 degree rotation should have to implement extra work for forwards/backwards compatibility. 3) The system already decides which side is top whether the rotation is 90 or 270 degrees. 4) android.view.Surface has no setRotation(...) method, it uses setOrientation(...). Thus, if Display#getOrientation() was to be deprecated, the same should have happened to Surface#getOrientation for architectural symmetry. 5) Using Display#getOrientation() will always be desired by some applications, whereas Display#getRotation() will always be desired by others. The frustrating factor here is that on top of the confusion caused by the SDK having different classes/methods to get runtime orientation versus configured orientation, this deprecation is poorly motivated.

You need to launch the default browser with your donation URL. After
that, the browser app should take care of the further actions.
To launch the Browser, you need to use a VIEW intent like this.

I have only had one customer complain of a problem since I upgraded to LVL.

[android-developers] Re: One process, two live Application objects?
From Dianne, That said, my recommendation to everyone is to just not subclass Application. This gives you *nothing* you can't do in other, better ways. In particular, a singleton directly represents what is really going on (it lives for the life of the process after the first need for it) and helps keep code more modular.

As far as using Application to clean up statics -- this simply doesn't really make sense, for the reasons above. I confess to using an Application subclass to clean up statics in my application and I would be glad to repent if I knew how. Dianne, is there a sample application in the SDK (or elsewhere) showing the best practice for collecting statics in a static singleton? The SDK documentation about singletons at http://developer.android.com/resources/faq/framework.html seems to suggest the use of an Application subclass: There are advantages to using a static Singleton, such as you can refer to them without casting getApplication() to an application-specific class, or going to the trouble of hanging an interface on all your Application subclasses so that your various modules can refer to that interface instead. But, the life cycle of a static is not well under your control; so to abide by the life-cycle model, the application class should initiate and tear down these static objects in the onCreate() and onTerminate() methods of the Application Class.

Re: [android-developers] button click
I'm going the crystal ball way here. You need to take the current content of text view (or save it somewhere) and when you press the button next time, take that content (or it's id or something like that, really depends on what you are trying to do and how) and then select next content based on current one. If you are trying to show, for example, tags from your xml, I would suggest parsing the whole file on first button press and save the tags along with their ids (reflecting their position in the file), then just selecting next id on next button presses.

If you don't have a MIME type, don't use anything. Let's back up... *why* are you doing this? Unless you need intent resolution to interact with other applications, my first suggestion would be to simply not use it. I also see a red flag in that you are talking about what looks like alarms but using registerReceiver(). Generally you wouldn't use these two together -- the only reason to use an alarm is to allow your application to execute at the time even if it is not currently running. Using registerReceiver() means that your application needs to be actively running with the registration to receive the broadcast. Generally it just doesn't make sense to mix both of these. If you are doing an alarm, usually the PendingIntent you create is an explicit Intent set to the ComponentName of a receiver component declared in your manifest. For that case, you don't need an intent-filter at all, and in fact anything you specify for it will be ignored (since you have already specified the exact component you want to receive it). Diahn Hackborn mentioned that the data part is used to distinguish PendingIntents.

[android-developers] Re: How can I create an aircraft-mounted-liked compass?
I do wonder how accurate it could possibly be, however. Your standard compass can be led astray by a steel belt buckle, so it's hard to see how a compass inside a phone, with batteries, printed circuits, electrons whizzing around, etc, could be very accurate at all.

I confess to using an Application subclass to clean up statics in my

there a sample application in the SDK (or elsewhere) showing the best
practice for collecting statics in a static singleton? The SDK
documentation about singletons at
http://developer.android.com/resources/faq/framework.html
seems to suggest the use of an Application subclass: There are
advantages to using a static Singleton, such as you can refer to them
without casting getApplication() to an application-specific class, or
going to the trouble of hanging an interface on all your Application
subclasses so that your various modules can refer to that interface
instead. But, the life cycle of a static is not well under your
control; so to abide by the life-cycle model, the application class
should initiate and tear down these static objects in the onCreate()
and onTerminate() methods of the Application Class.
Gah I'll get that removed from the documentation.
It is just totally wrong to rely on onTerminate. There is just
fundamentally no reason to worry about cleaning up your statics when the
way your process goes away is by killing it. There isn't anything to clean
up. And anyway, onTerminate never gets called.
Implementing a singleton is not special on Android; you just do it the same
way you would elsewhere. Have a static method that returns the singleton:
class Singleton {
static final Object sLock = new Object();
static final Singleton sInstance;
static getInstance() {
synchronized (sLock) {
if (sInstance == null) {
sInstance = new Singleton();
}
return sInstance;
}
}

In answer to the original query, there are four conceptual ways I can think of to do the job: 1) Paint the letters and hash marks under program control 2) Have an image that goes, say W..N..E..S..W..N..E and slide it back and forth as needed 3) Have images W, N, E, S, and several .. images of different lengths, and tile together the desired image. 4) Have about 32 complete separate images and select one On Oct 31, 3:51 am, josef.hardi josef.ha...@gmail.com wrote: I want to create a non-generic compass that uses rotating directions instead of a rotating needle as in the conventional compass.

Re: [android-developers] One process, two live Application objects?
Given this strong recommendation against subclassing Application, I'll look to avoid doing so in future projects, but when you say [subclassing Application] gives you *nothing* you can't do in other, better ways. the main benefit that comes to my mind is that you can expose static accessors for singletons that need a basic context (nothing more than the application context provides), without being required to pass it in. This occurs frequently in my code - I often have a number of independent static classes that deal with things like image caching. These types of classes invariably need a context during initialization (eg. to open databases or files) even if they don't need them at any later time. Objects within the app that aren't tied to any particular component's lifecycle are often the very same objects that need to interact with caches - ensuring that every such object has access (possibly indirectly of course) to a suitable context with which to access the cache will be a lot of work. In this case, I'm pretty sure that subclassing the Application object is giving me something; it's reducing the amount state that my objects need to carry (state which is almost always redundant since only one call to the accessor will ever need to create the singleton; it also allows me to avoid a synchronized lazy instantiation that would otherwise be necessary for some singletons). I think what's essentially providing this benefit, isn't the subclass of Application per se, but the presence of an reliable event (the call to Application.onCreate in this case) that precedes the instantiation of all other components, and which signals that the availability of the Application context. Without this, everything else carries the burden of providing an initializing context. My understanding of application start-up very incomplete, perhaps it's the provision of such an event (in whatever form) that causes difficulties at a platform level, and/or maybe there's some better way that bypasses the Application class.

[android-developers] Vertex buffer object corruption on MSM720xa
Hi there, i was refactoring some of my code today and wanted to minimze buffer object binds. My use case is it to bind a vertex buffer/index buffer pair once and batch up rendering as much as possible. Each batch is uploaded to the currently bound vbo. This works as expected on all tested devices (Nexus One, Droid, Samsung Galaxy) but fails on the HTC Hero with stock Android 1.5. I haven't updated the Hero to test exactly that kind of problems. I have compiled a small in depth description with a reproduceable test example. Both can be found at: http://www.badlogicgames.com/wiki/index.php/Severe_Bug_Updating_Already_Bound_Buffer_Object#Sample_Code I consulted with a couple of people whom i consider OpenGL experts and they all agreed that the way i handle the vbo/ibo is indeed correct and standard compliant. It would help if some people with an update Hero could try it out and see whether the problem persists. Should i file a bug on the Android bug tracker? -- You received this message because you are subscribed to the Google Groups Android Developers group.

for the method. NoSuchMethodException is somewhat more esoteric
The advice he actually needs is beyond the scope of this group. But
I'll sum it up:
Learn to use the debugger. Running it under the debugger, set up to
stop on RuntimeException and Error, would leave it stopped at the
problem line, with a ClassCastException on the stack, and thus neatly
answer your question for you, in far less time than it took to ask
this group. And that skill will pay off many times a day.

to a SensorManager is not going to go well for you. You're probably
getting a NoSuchMethodException, yes?

Re: [android-developers] Re: Linkify
Hi,
Thanks for the reply.. I am trying to do what you said.
I defined a string:
string name= support_requestSupport Request: a href=
supp...@unl.com?subject=commentssupp...@unl.com/a/string
In my .java code, I created a textview and called the setMovementmethod like
this:
TextView emailLink;
emailLink = (TextView) this.findViewById(R.id.support_request);
emailLink.setMovementMethod(LinkMovementMethod.getInstance());
I am getting the error below when I run the app and click on the email text:
11-01 02:44:42.431: ERROR/AndroidRuntime(1870):
android.content.ActivityNotFoundException: No Activity found to handle
Intent { act=android.intent.action.VIEW
dat=supp...@unl.com?subject=comments(has extras) }
I think I am missing something in the manifest file. I am not sure what I
need to fill there. Whar do I enter in the data field in the intent filter?
Here is my intent filter I have defined in the corresponding activity:
intent-filter
action android:name=android.intent.action.VIEW/
category android:name=android.intent.category.DEFAULT/
category android:name=android.intent.category.BROWSABLE/
data android:scheme=http android:host=supp...@unl.com/
/intent-filter
I think I am doing something wrong here.
Please Help.
Thanks,
Priyank

I haven't gotten autoLink/Linkify to work with subjects, but I have
used explicit mailto href values that included the subject parameter
in TextView views successfully. The way I did it the string in the
strings XML has a literal anchor tag in it with the mailto href
including a subject parameter. I set the string via the text attribute
on the TextView in XML and the HTML link gets converted properly. Then
I also call:
setMovementMethod(LinkMovementMethod.getInstance());
On the TextView from code. The amount of HTML a TextView will parse is
limited, but apparently it is enough for mailto links with subject
parameters, at least.

Hi,
I am stuck at a place when I was using Linkify to create Link an email
id to the Android email app.
I have a large sentence in a textview which has an email id. On
clicking on it, it opens my android email app. But The problem is
that, I cannot add any subject or message in the mail. Is there any
way of doing this using linkify ? Or do I have to use any other way
for doing this.
I initially used a textview which had just the email id, from which I
could add the subject and message, but i will have to keep the email
id in a separate line. I want the entire line in the textview where
the email id comes in the middle of the sentence.
I am currently doing like this:
TextView emailLink;
emailLink = (TextView)
this.findViewById(R.id.support_request);
Linkify.addLinks(emailLink,Linkify.EMAIL_ADDRESSES);
Thanks,
Priyank

[android-developers] Re: One process, two live Application objects?
Well, I've never expected onTerminate to be useful, but subclassing Application is. The Application's onCreate() method (and any static and instance initializers) are called before ANY application component is created or loaded. There's no other way to make this guaranty that I am aware of. You can come close if you put a reference to a singleton in every single component, and remember to always do so. But that's not a good approach -- it violates once-and-only-once. And if you're using third- party code as part of your app, it may not be possible. Although, admittedly, such code reuse is rare and problematic on Android, so it's nearly always possible. But why campaign against Application? It's a perfectly fine singleton itself, it's just misunderstood. Fix the documentation. Deprecate onTerminate. Suggest to people that their modularity would benefit if they group related statics into their own singleton, and their memory use might even improve if they then reference this singleton only where it's needed.

There is just fundamentally no reason to worry about cleaning up your statics when the way your process goes away is by killing it. There isn't anything to clean up.

[android-developers] Re: How can I create an aircraft-mounted-liked compass?
I may know more about magnetic compasses than some of the engineers putting them in devices...but of course, I don't know what those engineers are doing. But let me try to address the question in general terms anyway. Consider that traditionally, huge iron ships could use magnetic compasses with fair accuracy. How did they do this? Well, you may have seen pictures of a ship's compass, with two big iron balls on either side of it? The purpose of those balls is to allow the local magnetic field to be flattened, so the effect of all that iron, much of it magnetized by arc welding, would be balanced out and made more uniform in all directions. They are placed side-by-side, to compensate for the fore-and-aft alignment of the ship, and independently adjustable for compasses not on the ship's centerline. Then once the field was flattened, the compass would be calibrated by a specialist. As best I recall the procedure, the ship would be run back and forth in calm waters on each heading, and the discrepancies recorded, to be applied to headings and bearings taken using the compass. The ship's compass is filled with a fluid, with vanes attached below, to provide damping and to keep it level. All of this could better be done electronically, in software, working from the raw sensor data. But, of course nobody actually calibrates a phone this way. The manufacturer's could, but I seriously doubt they do. But I don't think there's any real reason for them to do so -- because how accurately can you judge the orientation of your phone relative to your heading? And without the little pin in the middle for you to sight against the distant object, how well can you peer over your phone and just the bearing of the distant object? I expect that details like this outweigh any sensor accuracy issues. As for batteries -- those should have no effect. They generally won't have ferrous metals. The currents involved are small -- and so long as they are relatively constant, on a reasonable timescale, at most they'd be something that could be taken care of in the calibration process, were there such a process. But I wouldn't be surprised to see something like a camera flash LED being lit, or the battery being charged, making a noticeable difference. That could also be addressed in software, but could also be addressed by carefully separating the sensor from the LED current. The bottom line is, that while I think phones could be quite accurate, I see no advantage in doing so, because if you need that kind of accuracy, you will be better served by a compass with a physical package designed for the purpose. These days, many of those are electronic using the same technologies as are found in the phone. You can get them built into binoculars, even. On Oct 31, 3:39 pm, DanH danhi...@ieee.org wrote: I do wonder how accurate it could possibly be, however. Your standard compass can be led astray by a steel belt buckle, so it's hard to see how a compass inside a phone, with batteries, printed circuits, electrons whizzing around, etc, could be very accurate at all.

Although, admittedly, such code reuse is rare and problematic on Android, so it's nearly always possible. Hm, so when do you need to just have code start running in your process first thing? Generally it needs to run for something else -- and that something else needs to make a call somewhere to get what it wants. Having that call Singleton.getInstance(context) (at which point you can do init for the first call) isn't any harder that ((Singleton)context.getApplication()), and it has some significant benefits: - Does lazy initialization so that you don't end up doing more stuff than needed when launching the process (important for first launch speed, and if you do things like receive broadcasts in the background). - Avoids Application is basically a big global. This also is far better for third party code, since if that code wants to have some global state it would be a pain to require modifying Application or having the app call into the library to init it. I don't understand your comment about violating once-and-only-once -- the whole point of a singleton is that it is one instance that is initialized the first time it is needed. There isn't actually any extra code you need to write to have it initialized, because by definition there is something there your other code needs, so the initialization can happen as a side-effect of getting access to it. But why campaign against Application? It's a perfectly fine singleton itself, it's just misunderstood. Fix the documentation. Deprecate onTerminate.
