Re: [android-beginners] Re: Database handling - when do you open and close
No, calling Thread.sleep() won't work.
Android framework is largely single-threaded, event-driven.
This means that your application and the framework run on the same
thread, passing control to each other, doing work in small pieces. This
thread is called the UI thread, and blocking it by calling sleep() can
do only one thing - cause the Application Not Responding dialog to appear.
The right thing to do is call bindService, and return from onResume.
You've done your piece of work (responded to onResume, and requested
that Android bind a service). Now you need to give Android a chance to
do its piece of work - by returning from onResume into Android framework
code, which will start the service (if necessary) and bind it, notifying
your callback.
Then it's your turn again - once in the ServiceConnection callback, you
know the service has been bound, and you can talk to the service and
ultimately populate the UI.
So that's basically the scheme with services.
You might also want to look at ContentProviders. They have a few
advantages over Services for this case - their lifecycle is managed by
Android, access is synchronous (using ContentResolver), and they handle
propagating data changes to existing queries / cursors (so if you have a
ListView, its data will be live).

Did you mean that? Now it should wait until the mDatabaseBinder is set
which should be in the onServiceConnected() method but that code
results in an endless loop, mDatabaseBinder stays null. Maybe I got it
wrong how the components work together. As far as I understood it, you
have a service running in the background, which returns a binder in
onBind(). The service connection fills the binder
onServiceConnected() so it can be used in the activity to access the
services variables. Is that wrong?

Re: [android-beginners] Re: Database handling - when do you open and close
Starting / binding to a service is asynchronous. You can't call bindService
and expect it to be already started and bound by the next line.
Call bindService and return control to Android by returning from onCreate or
whatever. Your service connection callback will be invoked a little later,
once the service is started.

Thanks for your reply, and sorry for my late answer. :-)
I tried to get it running as a service but I don't really get how I
have to use services, binders and service connections. I'm reading a
book with an example for services but can't adopt it to my problem.
What I tried is the following:
I created one class for the service, which holds the variable for my
database:
__
public class DatabaseService extends Service {
public DbAdapter mDbAdapter;
private DatabaseBinder mDatabaseBinder = new DatabaseBinder();
@Override
public IBinder onBind(Intent intent) {
return mDatabaseBinder;
}
@Override
public void onCreate() {
super.onCreate();
mDatabaseBinder.mDatabaseService = this;
mDbAdapter = new DbAdapter(getApplicationContext());
mDbAdapter.open();
}
@Override
public void onDestroy() {
super.onDestroy();
mDatabaseBinder.mDatabaseService = null;
mDbAdapter.close();
}
}
This is my database binder:
__
public class DatabaseBinder extends Binder {
public DatabaseService mDatabaseService;
public DbAdapter getDbAdapter() {
return mDatabaseService.mDbAdapter;
}
}
And this my service connection:
__
public class DbServiceConnection implements ServiceConnection {
DatabaseBinder mBinder;
public DbServiceConnection(DatabaseBinder binder) {
mBinder = binder;
}
@Override
public void onServiceConnected(ComponentName className, IBinder
binder) {
mBinder = (DatabaseBinder) binder;
}
@Override
public void onServiceDisconnected(ComponentName arg0) {
}
}
If I want to use this in my activity with this:
private DatabaseBinder mDatabaseBinder;
private DbServiceConnection mServiceConnection = new
DbServiceConnection(mDatabaseBinder);
final Intent databaseServiceIntent = new Intent(this,
DatabaseService.class);
this.bindService(databaseServiceIntent, mServiceConnection,
Context.BIND_AUTO_CREATE);
mDb = mDatabaseBinder.getDbAdapter();
I'm getting a nullpointer exception at the last line. I don't know if
I'm using it right (I guess not :D ), I haven't used services before.
Do you know why it is throwing a Nullpointer exception? Is this the
right way to use a service and bind it in the activity or should I do
it somehow different?

Re: [android-beginners] SecurityException in AccountManager.get(mContext).getPassword(account);
Looks like Google has a special process that deals with account
management. Only this process is allowed to get / set account passwords.
It's probably also signed with a special key, which is checked by the
kernel when it's started (guessing here).
If any application was allowed this, think how many web sites would be
offering Google account passwords - 1,000 for $10.-, and 10,000 for
$75.- (a 25% discount! only this month!)

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

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

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

Notice the act=com.shipmate.AboutShipMateActivity part. That says

Re: [android-beginners] Re: Loading images in android
The code below replaces the activity's content view (the root of view hierarchy) with a new LinearLayout. If you want to keep your existing layout around, do this: 1 - declare a LinearLayout placeholder in your layout xml file, give it an ID. 2 - instead of creating a new LinearLayout, get it by calling findViewById. 3 - don't call setContentView -- Kostya 28.07.2010 8:13, ethan пишет: This is the code that i used : LinearLayout mLinearLayout; mLinearLayout = new LinearLayout(this); ImageView i = new ImageView(this); i.setImageResource(R.drawable.cow_icon); i.setAdjustViewBounds(true); // set the ImageView bounds to match the Drawable's dimensions i.setLayoutParams(new Gallery.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); //Add the ImageView to the layout and set the layout as the content view mLinearLayout.addView(i); setContentView(mLinearLayout); With this code, i can see the image getting didplayed but it goes on a different layout.

Re: [android-beginners] What is drawable-hdpi, drawable-ldpi and drawable-mdpi ?
Shaista, drawable is the default. If a higher or lower resolution image is needed, depending on the screen, Android can scale it as appropriate. However, this automatic scaling doesn't always look that great. In those cases, you, as the developer, can provide alternate versions of the same resource in appropriate folders. They will override automatically scaled resources from drawable as appropriate based on the resource directory name (i.e. hdpi for high-density screens, etc.). This gives you fine grained control: some drawables can be scaled automatically (if this scaling looks good to you), and others can have alternate (high-res or low- res) versions. -- Kostya 27.07.2010 13:51, Shaista Naaz ?: Thanks for this, but I have a confusion that say I need to put one image into the drawable folder to run it in eclipse, where should i keep it, I mean in which folder or should I keep it in all the three?

Re: [android-beginners] Changes required to handle dual orientations
Bret, You use the same layout XML file names and same widget IDs in both files - that way, orientation changes (and other alternate resources) are completely transparent to the application code. But it's res/layout-land, not res/layout/land.

I guess this is due to either 1) We need different resource IDs for the two different orientations or 2) I need some changes in the manifest to tell Android that I'm using res/layout in one orientation and res/layout/land in the other for that activity.

Something's got to be different.

[Ask] VPN connection to Windows XP environment (without blue
screening)
I have a laptop running Windows 7. I need to connect and use my laptop
(running Windows 7) in an IT environment which is still running
Windows XP SP2.
I have had some issues with running a Windows XP-based VPN client on
my Windows 7 laptop, resulting in a blue screen.
I'd like to figure out whether VMWare (or other) has a product that
will enable me to do the following:
* Establish a Windows XP virtualized environment on my Windows 7
laptop (64 bit).
* Note that I don't have a Windows XP license on my laptop (only a
Windows 7 license).
* Securely connect using Cisco VPN client to an IT environment that is
still running Windows XP SP2.
* Need to make sure that my Windows 7 laptop is unimpacted (i.e., does
not blue screen) by any Windows XP application that I launch within
the virtualized environment.
* My Dell-based laptop (Latitude, D620) is a 64-bit architecture
running Win 7 Enterprise.
* Need to achieve secure (VPN-based) access to Win XP environment in a
corporate setting.
* Not for demo purposes where I am playing with multiple OS'es.
* Will also need to use Win XP version of Outlook and run MS Office
apps within virtualized Win XP environment.
* Is there a way to leverage MS Office 2007 version of the apps
installed in Win 7 (within the Win XP environment)?
Can a business user (who is not technically savvy) install the product
(assuming one exists)? What is the cost of the product?
Thanks for any feedback.
Long Story Short: This question is still in discussion mode and
resolved as a parking lot issue in Win*land. The poor user (me) is
not exactly a happy camper. Can Android come to the rescue?

Re: [android-beginners] Force close issue!
At this point, let the application run until you get a force close dialog on the device. Then check logcat (in Eclipse or adb logcat from the command line) to find out the cause - it will be in the stack trace, under Caused by:. The message about JAR means that the crash is somewhere inside Android - possibly you are passing a null pointer to some method, or forgot to declare something in the manifest. This is nothing to be especially concerned about - check logcat and eliminate the cause. -- Kostya 21.07.2010 10:13, Linh Le пишет: I am having problems right when I run the program. Whenever I use the original file, it runs fine. However, for the file I made edits too, it always sees to force close itself.

Re: [android-beginners] Returning values from dialog
Try removing 'final' from 'final mytitle'.
'final' in Java means you are telling the compiler you are going to assign
the value once, a kind of self-check. Consequent assingments are flagged as
an error.

Re: [android-beginners] Re: Including libraries in project
During compilation, Android tools use standard Java .class format, as you found out. However, during application packaging (I think) they are converted into Dalvik's special format, .dex, which does not use Sun's Java bytecode. If you list the contents of an .apk file, you will see one .dex file instead of multiple .class files, as would be the case with a regular Java application. http://en.wikipedia.org/wiki/Dalvik_(software) -- Kostya 17.07.2010 17:06, DanH пишет: That's not been my impression, and when I browse an Android class file with a hex editor it says CAFEBABE.

Re: [android-beginners] The Force Close Error is suddenly back...
Victoria,
The cause of this exception appears in logcat:
07-16 19:40:45.124: ERROR/AndroidRuntime(225): Caused by:
java.lang.NullPointerException
07-16 19:40:45.124: ERROR/AndroidRuntime(225): at

Looks like vidUris is null.
Set a breakpoint and debug - looks like adapter's getCount() gets called
before the information (vidUris) becomes available.

Re: [android-beginners] The Force Close Error is suddenly back...
So far so good, you've successfully hit a breakpoint. Now you need to inspect variables (Google for Eclipse debugging basics). Also set a breakpoint whee data is handed over to the adapter, and see which one gets hit first. BTW, I think adding if (vidUris != null) inside getCount() will fix the crash for now, but still - learning how to debug and understand what the code actually does during execution is instrumental to any further development work you plan on doing. -- Kostya Vasilyev -- http://kmansoft.wordpress.com 17.07.2010 2:15 пользователь Victoria Busse victoriasarabu...@gmail.com написал: Okay, I set the breakpoint for getCount(); and this is what I got... terminatedMoved [Android Application] disconnectedDalvikVM[localhost:8615] Moved [Android Application] DalvikVM[localhost:8615] Thread [3 main] (Suspended (entry into method getCount in EditGalleryView$VideoAdapter)) EditGalleryView$VideoAdapter.getCount() line: 74 GridView.setAdapter(ListAdapter) line: 128 EditGalleryView.onCreate(Bundle) line: 28 Instrumentation.callActivityOnCreate(Activity, Bundle) line: 1047 ActivityThread.performLaunchActivity(ActivityThread$ActivityRecord, Intent) line: 2459 ActivityThread.startActivityNow(Activity, String, Intent, ActivityInfo, IBinder, Bundle, Object) line: 2335 LocalActivityManager.moveToState(LocalActivityManager$LocalActivityRecord, int) line: 127 LocalActivityManager.startActivity(String, Intent) line: 339 TabHost$IntentContentStrategy.getContentView() line: 648 TabHost.setCurrentTab(int) line: 320 TabHost.addTab(TabHost$TabSpec) line: 213 GalleryView.onCreate(Bundle) line: 28 Instrumentation.callActivityOnCreate(Activity, Bundle) line: 1047 ActivityThread.performLaunchActivity(ActivityThread$ActivityRecord, Intent) line: 2459 ActivityThread.handleLaunchActivity(ActivityThread$ActivityRecord, Intent) line: 2512 ActivityThread.access$2200(ActivityThread, ActivityThread$ActivityRecord, Intent) line: 119 ActivityThread$H.handleMessage(Message) line: 1863 ActivityThread$H(Handler).dispatchMessage(Message) line: 99 Looper.loop() line: 123 ActivityThread.main(String[]) line: 4363 Method.invokeNative(Object, Object[], Class, Class[], Class, int, boolean) line: not available [native method] Method.invoke(Object, Object...) line: 521 ZygoteInit$MethodAndArgsCaller.run() line: 860 ZygoteInit.main(String[]) line: 618 NativeStart.main(String[]) line: not available [native method] Thread [13 Binder Thread #2] (Running) Thread [11 Binder Thread #1] (Running) As I am really new to all this, I don't really have clue what it means... :p On Fri, Jul 16, 2010 at 10:54 PM, Victoria Busse victoriasarabu...@gmail.com wrote: Thanks :... -- You received this message because you are subscribed to the Google Groups Android Beginners gr... -- You received this message because you are subscribed to the Google Groups Android Beginners group.

Re: [android-beginners] Re: Database handling - when do you open and close

because i'm using the db in almost every method. I hope there is
another solution for it..

If you open the db only in onResume() it should be fine (although I didn't
try it by myself). Usually, when I need data from the db, I call db.open(),
fetch my data, and db.close(). In this way I'm pretty sure there won't be
any such leak. Still I don't know if that's the best way to do it.

Re: [android-beginners] Canceling an Alarm in an AppWidget
Jake,
AppWidgetProviders are transient, you can't store any data in these
objects. They are created by Android as necessary and are destroyed,
from what I see with my widgets, quite aggressively.
Canceling an alarm doesn't require the same Java object you used to set
an alarm.
Just create another PendingIntent with the same values, and call
cancel() with this new object.
This will remove the need for storing data in AppWidgetProvider instance
variables, which you can't do.

Re: [android-beginners] Re: Canceling an Alarm in an AppWidget
Jake,
It isn't and it doesn't.
I know it's a little counter-intuitive, but that's the case.
AppWidgetProvider is just a special BroadcastReceiver. It is
instantiated by Android runtime / home screen in response to events
defined in the manifest, and provides a RemoteViews object that defines
widget state. After that it (its process) can get killed, and
instantiated next time it is needed to handle a broadcast.
Heck, even home screen orientation changes don't cause AppWidgetProvider
to be instantiated - Android just uses the most recent RemoteViews it
saves somewhere.

Clearly, I can do as you suggest; I'd just like to understand why it's
necessary.
Thanks.

Re: [android-beginners] Implementing a Service - Call down to super?
Calling the base class is required for IntentService and its subclasses
(such as Mark Murphy's WakefulIntentService).
16.07.2010 1:09 пользователь Justin Anderson janderson@gmail.com
написал:
Jake,
You haven't given enough information to determine if it should be called
before or after your stuff. And it also depends on what the Service
constructor does (which I don't know because I haven't looked at the source.
I guess the point I am trying to make (that it totally depends and can't be
answered as generically as you want it to be) is best illustrated with an
example:
public class Foo
{
protected int x;
public Foo()
{
x = 3;
}
}
public class Bar1 extends Foo
{
public Bar1()
{
super();
x = 5;
}
}
public class Bar2 extends Foo
{
public Bar2()
{
x = 5;
super();
}
}
In the example above, x will have the value 5 after the Bar1 constructor
finishes but Bar2 will have the value of 3 after the constructor
finishes
So, as I said before, it completely depends on what the super class does and
what the subclass is doing. I have not looked at the source code for
Service and I don't know what your subclass does so I don't know what case
works best...
TreKing's comments are certainly valid though. From his observations it
seems that it does not matter. And if it did matter you could certainly
just try both and see which way works, as he also suggested.
Personally, I ALWAYS call super in my subclasses... Even if it is just a
placeholder hook.
Sorry that my answer was too generic. I couldn't be more specific with the
generic nature of your question.

Re: [android-beginners] Re: closing multiple activities
Tollas, First of all, there is Activity.finish(), which closes the activity. But if the way you want your app to interact with the user doesn't fit the way Activities are managed by Android, perhaps you can consider switching views inside an Activity? You can call setContent at any time to switch the layout, and obtain any necessary UI objects for the new view hierarchy (such as buttons, etc) - the stuff you normally do in onCreate(). Another option is to use a ViewFlipper, this way the entire layout with all of its variations can be loaded at once. Then you could handle the back key to return to previous layout or view (if using a ViewFlipper). This might be easier to implement than trying to bend Activities life cycle. -- Kostya 02.07.2010 23:19, Tollas пишет: All activities are developed by me.

Re: [android-beginners] Triggering an AppWidget Update
Jake, There are two scenarios involved: 1. Android calls the widget provider's onUpdate() - when the widget is first shown and then regularly at updatePeriodMillis intervals, if specified. Note that automatic updates based on updatePeriodMillis are limited to once every 30 minutes since Android 2.x. 2. You are free to update your widgets any time, by doing something like this: ComponentName thisWidget = new ComponentName(context, MyWidgetProvider.class); AppWidgetManager manager = AppWidgetManager.getInstance(context); RemoteViews updateViews = .. specify new widget state here .. manager.updateAppWidget(thisWidget, updateViews); For your calendar example, obviously the second scenario has to be involved. As for performing updates when necessary (and only then), your code needs to contain some logic to figure out the appropriate time for the next update (based on actual calendar events and how much in advance they are supposed to be displayed). Then set an alarm using AlarmManager to update the widget. Note that AlarmManager does not have to be used in a service, although sample code typically does. An alarm simply fires off a PendingIntent. This intent can be specific to your code, triggering a widget update just in time to for next scheduled calendar event. A good place to receive this special intent is in your AppWidgetProvider - since it's a BroadcastReceiver anyway. Hope this helps. -- Kostya 24.06.2010 18:31, Jake Colman пишет: I have some questions about the correct approach for updating an AppWidget's display. Since this is a beginners forum, please let me state what I already do know: 1) I can use android::updatePeriodMillis to specify the update interval. When this interval has elapsed the phone is woken up. Intervals of less than one hour are not a good idea. 2) Updates can be triggered by an alarm that will not actually wake up the phone. What I'm confused about is how/why/when to trigger an update. Let's say I am creating an AppWidget that will display the time of my next appointment. The widget needs to know the current time and the time of my next appointment. When the current time is after the current appointment the widget has to display the time of the next appointment. For this widget to work it must be regularly checking the time and the calendar since at any minute it might be time to display the next appointment. Does this mean I have to update the widget's display every minute? Clearly not, but how else? In actuality, I only really need to update the display if the user is looking at the screen. But do we only update if the screen is active? If so, what about if that update is a time-consuming process? The UI would then appear non-responsive. So what the is correct approach for this kind of problem?

Re: [android-beginners] Re: Triggering an AppWidget Update
Jake, There are two issues here: - Getting notifications when appointment data changes. If the appointment database is your own, set up an intent to be fired whenever there is a change. If you are using the built-in calendar, there is got to be a way, too - I just don't have any pointers not having used this API. - Time until next appointment changes with real wallclock time, so it would have to be updated (every minute? every second?). This is a UI design decision - do you think your users prefer to see time til next appointment with 1-second accuracy, at the expense of possibly poor battery life, or would they be happy with 1-minute resolution, or perhaps just time of next appointment, updated a few times a day? -- Kostya 24.06.2010 19:11, Jake Colman пишет: But let's say the appwidget displays the amount of time remaining until the next appointment.

Re: [android-beginners] Re: Triggering an AppWidget Update
Jake, The 30 minute minimum intervals only applies to updates specified in the widget's XML file (updateTimeMillis). You can have alarm-driven (or other event driven) updates as often as you like, so it's only a question of judgement with respect to battery life. Android 2.x includes analog clocks that update once a minute, so it can't be that bad. Avoiding updates when the screen is off is pretty easy - just use alarm options without the _WAKEUP (i.e. ELAPSED_REALTIME or RTC). If such alarm goes of while the phone is asleep, it will be delivered when the phone wakes up. -- Kostya 24.06.2010 19:36, Jake Colman пишет: But in the second example, would it be appropriate to update every minute? But Android 2.2 only allows an update every 30 minutes. Do you set an alarm to trigger even minute or would that also drain the battery? Do you trigger an update only when the screen is turned on? Can that even be detected? -- Kostya Vasilev -- WiFi Manager + pretty widget -- http://kmansoft.wordpress.com -- You received this message because you are subscribed to the Google Groups Android Beginners group.

Re: [android-beginners] Problem with AppWidget Using a Service
Jake,
The error is in the way your code instantiates ComponentName.
Instead of:
ComponentName thisWidget = new ComponentName(this, ZMUpdateService.class);
Do this:
ComponentName thisWidget = new ComponentName(this,*ZmanMinderAppWidget*.class);

Re: [android-beginners] Re: onHandleIntent(Intent) method does not get called
Betty,
Make sure your service calls base class methods in onCreate() and
onStart(). Intents for processing are queued to a worker thread by
IntentService.onStart. The worker thread is set up by onCreate.
class BettysService extends IntentService {
@Override
public void onCreate() {
... logging here ...
super.onCreate();
}
@Override
public void onStart(Intent intent, int startId) {
... logging here...
super.onStart(intent, startId);
}
.
}
BTW, Android source can be found here:

Thanks for replying. I also have a logging printout in the

If onStartCommand() is called, doesn't that mean my startService()
from my Activity has indeed started my IntentService?
Who ultimately calls onHandleIntent()? That's what I cannot figure
out from the docs.

Re: [android-beginners] Re: Problem with AppWidget Using a Service
Jake,
onUpdate is passed an explicit list of just the widget ids that need to
be updated. Supposedly, there could be widgets that belong to this
provider but don't need updating (e.g. on a scrolled-off home screen
portion).
Pushing a RemoveViews object to a paricular widget is done by calling:
manager.updateAppWidget(int widgetId, updateViews);
It's also possible to update all widgets that belong to a particular
widget provider, and this is the approach service-based widgets take,
supposedly to avoid paying service start-up costs for each widget id.
In this case, a single RemoteViews is pushed to all widgets with a
single call to:
manager.updateAppWidget(ComponentName thisWidget, updateViews);

Re: [android-beginners] Re: Problem with AppWidget Using a Service
Jake,
Using a service for a widget that's not doing anything lengthy to
prepare updates seems like a bit of an overkill. Certainly it works, but
probably not necessary.
On the other hand, using a service is definitely the way to go for
widgets that fetch data from the Internet or some other way that can
take a long time.
Another issue is - this is all good, until someone uses a task killer,
discovers the service, complains that the widget spanws an unnecessary
service that uses too much memory and cpu time, kills it, and
uninstalls. Has happened to me.
Good thing Android 2.x includes great tools to show how memory and
battery are used.
I hope users learn to use these tools and exercise good judgement before
killing a service just because it's there.

Re: [android-beginners] Transition animation for dynamic (single) view.
Since I was curious about this as well, I looked at the source you pointed at. They use a ViewSwitcher with two (or actually, more, dynamically created) content views. This makes sense, since ViewSwitcher animations involve two representations of content - old and new, hence at least two separate views to render them. -- Kostya 20.06.2010 23:08, Mark Murphy пишет: On Sun, Jun 20, 2010 at 2:48 PM, jared.thigpenjthi...@gmail.com wrote: Alll the examples I find for transition animations (push left out, push right in, etc.) deal with moving from one view to another.

James, The 30 minute limit only applies to automatic updates scheduled by using the widget .xml desciptor. Your widget provider can update its widgets (using the usual mechanism of RemoteViews) any time it wants. For example, in response to some other broadcast. In my application, this happens when in response to WiFi state changes. In yours, it could be something else. -- Kostya 01.06.2010 5:33, james pruett ?: Are you saying widgets can update faster than 30minutes?

You can build against 1.6 and set min-sdk to 3, also set supports-screens for high and low screen support.

For screens larger than baseline, the platform displays the application in a baseline-sized portion of the overall screen, against a black background. This is what's happening to me.

Re: [android-beginners] The Android emulator runs too slowly.
You don't need to recover from a crash in any way. When the app crashes, press Android's force close button, the same you'd do on a real phone. Then start debugging again (with or without changing the code and redeploying). -- Kostya 12.05.2010 19:44, T1000 пишет: I understand that if I could write an app that didn't crash every time, I could just quit the app and re run it (hypothetically). However, that is not the case. How do I recover from a crash in the emulator without closing the emulator and rerunning my app in Eclipse?

Just to be clear - you don't have to load up the emulator each time you run your app. You should load it once (which is known to take quite some time) and then leave it up as long as you're working on your project (or something goes wrong with Eclipse / adb / DDMS , etc, forcing you to restart). - TreKing - Chicago transit tracking app for Android-powered devices http://sites.google.com/site/rezmobileapps/trekinghttp://sites.google.com/site/rezmobileapps/treking -- You received this message because you are subscribed to the Google Groups Android Beginners group.

Re: [android-beginners] Re: Communicating between multiple Apps/Widgets?
That wouldn't work. App widgets are stateless by design. The way to implement what you want (from what I can tell) is to broadcast an intent when the user clicks on the widget and handle it in the AppWidgetProvider. To make the widget broadcast an intent when clicked, use PendingIntent with a custom (defined within your app) action string, and attach it to the view with RemoteViews.setOnClickPendingIntent. I have a post about this here: http://kmansoft.wordpress.com/2010/04/10/processing-widget-events-with-pendingintents/ -- Kostya 12.05.2010 20:19, repole пишет: Thanks for the quick response I figured the widget could store a variable that's altered on OnEnabled(), OnDisabled(), etc, and then the app could retrieve that variable from the widget...or would that note work?

Re: [android-beginners] Re: Communicating between multiple Apps/Widgets?
12.05.2010 21:02, Justin Anderson ?: /// App widgets are stateless by design./ True, but depending on what you are wanting to do, you can store state using SharedPreferences... Correct. It's also possible to store state in SharedPreferences, or SQLLite, or via a web service - but any of those is a mechanism external to AppWidgetProvider itself. The Java object declared in the manifest (AppWidgetProvider subclass) is stateless, and can (and will be) recreated and disposed of by Android. There are no guarantees about its lifetime - only that appropriate methods will be called upon relevant events. -- Kostya Vasilyev -- WiFi Manager + pretty widget -- http://kmansoft.wordpress.com/sw -- You received this message because you are subscribed to the Google Groups Android Beginners group.

Re: [android-beginners] Human interface guidelines. Equivalent to iPhone sectioned table
The Android Dev Guide does exist: http://developer.android.com/guide/practices/ui_guidelines/index.html It covers in detail how application is supposed to guide the user from one activity to another. However, it does not specifically cover your question. Perhaps you could use a list view, make it look like Android's built-in preference screens, with two-line items, each containing the name of action to be taken and its description in smaller text below. By adding nice graphics in the top portion of the view, and using a theme to set colors to something nice (other than the default white-on-black), I think can be made look quite good. -- Kostya Danny Pimienta danny...@gmail.com писал(а) в своём письме Wed, 05 May 2010 21:54:40 +0400: I would be interested in a answer to this as well.

In particular, when moving an app from the iPhone to Android, are there any conventions for equivalent UI controls or suggested UI design? On the iPhone, the sectioned table view is used to provide multiple choices for paths to follow through an application. What is the suggested equivalent on Android? Do any UI guidelines exist? I'm trying to come up with something that looks nice. The iPhone version has an image background surrounding the table. Some options I can think of include: - A series of buttons: Not sure if this will look cheesy. - A list view: Typically consumes the whole window. Doesn't look as nice as the iPhone version. - A list view inset in a window: I've done this before. Looks ok. Corners are not rounded like they are on the iPhone. Can do a background.

[android-beginners] Smarter widget updates
Hi, I have a widget that displays detailed WiFi state (SSID, signal, etc). It registers in the manifest to receive various android.net.wifi.* notifications. So far so good. However, these notifications are not sent if the home screen is side- scrolled, or phone is screen-locked. This is good - improves battery time and performance. The bad side of this, though, is that since WiFi state can change while the widget is not visible, I have to request frequent scheduled updates in my appwidget-provider xml descriptor to bring the widget completely up to date when it's scrolled into view or phone screen is unlocked. After the widget comes into view and is updated, further updates could be driven again by android.net.wifi.* notifications, but scheduled onUpdate()'s continue to run, which is a waste. Is there a way to register my AppWidgetProvider for a smart one-tme update when it's becomes visible, either after side-scrolling, or after the screen is unlocked? -- Kostya Vasilyev -- http://kmansoft.wordpress.com/sw/ -- You received this message because you are subscribed to the Google Groups Android Beginners group.
