[android-developers] = Returning images to the Quick Search Box Asynchronously =
The images returned to the cursor in the QSB seem to require an image on the device. My images live on a remote server that would have to be downloaded to the device asynchronously with callbacks. This would be prohibitively slow returning search results. Is there a way that the QSB can retrieve images from a remote server on its own, given the URL? Or perhaps can I return a URI that maps to a ContentProvider that returns the image? Any ideas?

[android-developers] Re: == How to Toast or Notify in response to ACTION_VIEW without showing my app ==
Nope. That doesnt work either.
Here is my code for the activity that responds to the QSB. You'll see
that I am using the application context for the toast.
My app shows with the toast over it. If it is possible to show a
toast over the QSB then how? (Example code)
public class GlobalSearchActivity extends Activity
{
@Override
protected void onCreate( Bundle savedInstanceState )
{
super.onCreate( savedInstanceState );
String extra =
getIntent().getStringExtra( SearchManager.EXTRA_DATA_KEY );
if( extra == null )
finish();
if( ActivityHelpers.isOffline() )
{
String message = You can not view this content while
offline;
Toast.makeText( getApplicationContext(), message,
Toast.LENGTH_SHORT).show();
finish();
}
else
{
Intent myIntent = new Intent( this, SplashScreen.class
);
myIntent.setAction( getIntent().getAction() );
Bundle extras = getIntent().getExtras();
if( extras != null extras.size() 0 )
myIntent.putExtras( extras );
try
{
this.startActivity( myIntent );
}
catch( ActivityNotFoundException
activityNotFoundException )

[android-developers] Re: == How to Toast or Notify in response to ACTION_VIEW without showing my app ==
The big problem here seems to be that the target of the Intent thrown from selecting a search suggestion in the Android Quick Search Box must be an Activity. If it could be a Service then I could simply show a toast from that if offline or start the appropriate activity if not. Nope. If its not an activity its not even searchable! But starting an activity shows the app with the activity on the top of the stack. So finish() simply shows the activity that was below it in my app's activity stack. Perhaps i can simulate a back button press after showing the toast. Its a hack though (can you even do that?)

I can get search results in my app's search area (selecting the app icon in the 2.3 quick search box to restrict the search to my app). However, i dont see any of my results when All is selected.

[android-developers] Re: == Populated MatrixCursor returned to the Global Search shows wrong results ==
The reason this happens is that Google hasn't updated their docs for
search in a long time and they are now completely out of date with
what the ACTUAL requirements are for cursor rows returned to the
Global Search Box. Also, they changed the required columns and
uniqueness requirements in 2.2 and didnt tell anyone about it. Google
needs to update these docs (http://developer.android.com/guide/topics/
search/adding-custom-suggestions.html). Not only are they wrong but
very hard to understand. They introduce WAY too much complexity up
front with a misguided emphasis on completeness. It is better to
start with several minimal examples that each illustrate a single
basic concept. Only then, after the basics have been introduced
should you provide more advanced details. Context before exposition.
Tech Docs 101.
Here's the REAL requirements:
BaseColumns._ID - This is documented as required and as a unique
INTEGER(long), whatever that means. It is required but as a unique
String up until android 2.1. The string need not be numeric (neither
an INTEGER or a long). It can be anything, but it must be unique.
After 2.1, it can be anything, even null. It doesn't matter. You
don't even have to include _id in the cursor at all.
SearchManager.SUGGEST_COLUMN_INTENT_DATA - This is documented as
optional. It is optional until 2.2, where not only is it a required
String but it must be unique! It is required whether you specify
android:searchSuggestIntentData in your searchable.xml or not. It
does not have to be a URL.
So, to be compatible with all versions of android (so far) you need
both lines. Like this:
private static final String[] SEARCH_CURSOR_COLUMNS =
new String[]{
BaseColumns._ID,
SearchManager.SUGGEST_COLUMN_TEXT_1,
SearchManager.SUGGEST_COLUMN_TEXT_2,
SearchManager.SUGGEST_COLUMN_INTENT_DATA,
SearchManager.SUGGEST_COLUMN_SHORTCUT_ID };
public Cursor query( Uri uri, String[] columns, String where,
String[] whereArgs, String sortOrder )
{
MatrixCursor cursor = new MatrixCursor( SEARCH_CURSOR_COLUMNS );
cursor.addRow( newCursorRow(uniqueId1, Android docs, Need
refactoring) );
cursor.addRow( newCursorRow(uniqueId2, Bait, and Switch)
);
return cursor;
}
private Object[] newCursorRow( String uniqueId, String text1, String
text2 )
{
return new String[] { uniqueId, // _ID
text1, // SUGGEST_COLUMN_TEXT_1
text2, // SUGGEST_COLUMN_TEXT_2
uniqueId, // SUGGEST_COLUMN_INTENT_DATA
SearchManager.SUGGEST_NEVER_MAKE_SHORTCUT }; //
SUGGEST_COLUMN_SHORTCUT_ID
}

[android-developers] == Populated MatrixCursor returned to the Global Search shows wrong results ==
I am trying to populate results for the global search box. I can
currently type in the search box and have my debugger stop in query()
just as I would expect. Just as a test I am populating a MatrixCursor
manually to return from the query() method. Here is the test code...
public class GlobalSearchProvider extends ContentProvider
{
private static final String[] SEARCH_CURSOR_COLUMNS = new String[]
{_ID,SUGGEST_COLUMN_TEXT_1,SUGGEST_COLUMN_TEXT_2,SUGGEST_COLUMN_ICON_1,SUGGEST_COLUMN_INTENT_EXTRA_DATA};
@Override
public Cursor query( Uri uri, String[] columns, String where,
String[] whereArgs, String sortOrder )
{
switch( uriMatcher.match( uri ) )
{
case GLOBAL_SEARCH_SUGGESTION_CODE:
{
return getSuggestionTest( whereArgs[0] );
}
default:
throw new IllegalArgumentException( Unknown
Uri: + uri );
}
}
private Cursor getSuggestionTest( String searchTerm )
{
MatrixCursor cursor = new MatrixCursor( SEARCH_CURSOR_COLUMNS );
if( searchTerm == null || searchTerm.length() == 0 )
return cursor;
ArrayListObject columnValues = new ArrayListObject();
columnValues.add( 0 ); // _ID
columnValues.add( Poofy and the Buttons);
columnValues.add( searchTerm );
columnValues.add( null );
columnValues.add( 0 );
cursor.addRow( columnValues );
ArrayListObject columnValues2 = new ArrayListObject();
columnValues2.add( 1 ); // _ID
columnValues2.add( Joe Mama);
columnValues2.add( searchTerm );
columnValues2.add( null );
columnValues2.add( 0 );
cursor.addRow( columnValues2 );
int nr = cursor.getCount();
return cursor;
}
}
Here is the searchable.xml
searchable
xmlns:android=http://schemas.android.com/apk/res/android;
android:label=@string/search_label
android:hint=@string/search_hint
android:searchSuggestAuthority=com.poofy.GlobalSearchProvider
android:searchSuggestThreshold=1
android:includeInGlobalSearch=true
android:searchSuggestIntentAction=android.Intent.action.VIEW
/searchable
And in the manifest
provider android:name=.GlobalSearchProvider
android:authorities=com.poofy.GlobalSearchProvider /
Very simple. It returns a cursor with two elements. The debugger
shows it working nicely... until you see that the search list actually
contains only one result with no text in it! Yes, I have enabled
search to get results from my app (or it would have never stopped the
debugger). Its as if the contents of the MatrixCursor is not
recognized by the system. (I have to use a MatrixCursor because my
results do not come from a database.)
Any idea what might be happening here?
Thanks

I am making a ContentProvider to provide results of the android global search box. I am supposed to @Override query() to return my results in a Cursor. The problem is that my results do not come from a database. They come from a server that gives me a populated ListContent. Perhaps I need to manually populate a new Cursor with my list contents.

All of my activities already uses android:configChanges=keyboardHidden|orientation in order to prevent them from doing this. We still get the error. Has anyone else seen this before?

[android-developers] Re: === IllegalArgumentException: View not attached to window manager ===
There are about 10 different dialogs and they are are all a little different. I have no idea which one it is coming from. I think this is a non-error. Dismissing a dialog that has already been destroyed by android is not really a problem. I'll just try-catch the exception at every dialog.dismiss(). -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Programmatically resizing a custom view?
I am trying to programmatically resize a custom view in android. The
custom view contains a Button and an EditText in a LinearLayout. I
want to make several instances of this custom view and alter the width
of each one slightly narrower than the last so that they overlap each
other. At what point can I do this and how?
If I override the custom view's onWindowFocusChanged() to set the
width using this.setLayoutParams( newWidth, LayoutParams.FILL_PARENT);
it crashes later on with a ClassCastException in the LinearLayout.
Like this...
@Override
public void onWindowFocusChanged( boolean changed )
{
super.onWindowFocusChanged( changed );
// reset the width
int fullWidth = this.getWidth();
if( fullWidth 0 )
{
int width = fullWidth - (20 * (viewNumber));
this.setLayoutParams(new LinearLayout.LayoutParams( width,
LayoutParams.FILL_PARENT));
}
}
So, obviously, this is not the way to do it. How then?
Thanks

[android-developers] Eclipse debugger is skipping instructions!
I am debugging an app that tests an API I wrote. There is a section of
code that simply reads a DB cursor like this:
Cursor row = mDatabase.query(properties, null, where, null, null,
null, null, null);
if( row != null )
{
if( row.moveToFirst() ) // A
{
int n=row.getColumnIndexOrThrow(value);
value = row.getString( n ); // B
}
}
The debugger steps through line at a time until it gets to the line
commented // A. The next line the debugger gets to is the line
commented // B!!! It completely skips over the int n =... line. Even
stranger, at that point the int n is not listed as being in scope at
all. Basically, as soon as it executes any method on row the debugger
skips.
I also have to step twice over each clause in any conditional. So
this: if( a==2 || b==4 ) would require four step over actions to get
past it. Very strange.
I re-installed the latest version of eclipse with the latest ADB and
the latest emulator. It still happens. This is running against Android
2.0, which is a requirement. I am on Windows 7 64 bit with a 32 bit
installation of eclipse.
Has anyone seen this strange debugger behavior? What should I try to
do?
Thanks.

[android-developers] Unseen GridViews in a ViewFlipper dont inflate?
Hello, I am having a problem with a calendar app i am writing. I have three GridViews within a ViewFlipper . Each GridView shows a month. The ViewFlipper responds to flings in order to flip to the next or previous month GridView and update the unseen GridViews. The problem is that while the first month shows perfectly the adjacent two months in either direction dont appear at all until the user has flinged past them to the third month away. So if I start in February, March wont show until I fling to May and then back to March. April wont show until I fling to June and back. However, once I fling to June all months show correctly and the calendar works perfectly in both directions. It would appear to be an initialization problem but the method that initializes the months is the same used to flip the months. All three months are initialized to now in the constructor and then flipped by 0, +1, -1 using the same method that flips them on fling. I thought that unseen GridViews might not inflate immediately, so I tried waiting for a few minutes before flinging and it still happened. I am calling onFinishInflate() everywhere things are being inflated and they are all called predictably. The GridView population happens in a separate thread, so I suspected that the GridView is displayed before the thread has a chance to finish running. However, this theory is suspect because the problem only happens on initialization. After three flings the whole thing works perfectly regardless of how fast or slow you fling it. At this point I am at a loss. When I tried this using TableLayouts instead of GridViews the fling initialization worked perfectly (but the grid was not uniform, so I cant use TableLayout). Is there some strange interaction between GridView and ViewSwitcher that prevents the unseen GridViews from rendering immediately? Any ideas?

[android-developers] How can a parent handle touch events BEFORE its children?
I have a custom view (A) that contains a ViewFlipper, which flips between three custom views (B1, B2, B3). Each B view is a LinearLayout containing a TextView and a GridView. The problem is that i need touch events on the GridView to be handled by the A view. This is so that fling events on any GridView get handled by the ViewFlipper. It seems simple enough... just make the touch listeners for the B views and GridViews return false, right? Wrong. It doesnt work. The B.onTouchEvent() is never called by touch events on a GridView and neither is ViewFlipper.onTouchEvent(). Strange but true, and I have the Logs to prove it. I tried passing an instance of the parent A view to each of the B views so that when a touch event happens I can dispatch all touch events to the parent A view. The result...an infinite loop and stack overflow because the A view first passes the event back to its children. How do I get a view to handle all of its touch events without passing those events to its children? In truth, i dont need children to respond to ANY touch events at all. Ideally, I would like ALL touch events to be handled by the A view and never by any of its children. Is there a way to force this?

I have a TableLayout where each cell of the table contains a single button or textView. I want to make sure that every cell has the same height and the same width. In other words all column widths are the same and all row heights are the same. Of course, it has to do this while resizing the TableLayout to its given layout_width and layout_height.

[android-developers] Re: findViewById doesnt work directly after inflate() !! Why?
I ended up changing extending a View to a FrameLayout. This way I
can use it as the root in inflate because it is a ViewGroup. I think
the problem was that having a null parent in an inflate doesnt
actually render the views. I may be wrong about this but it worked
for me.
Caching the subviews in onFinishInflate() is a good idea, so i did
that too.
Thanks.

[android-developers] Why aren't ACTION_UP and ACTION_MOVE Touch Events passed through to custom views?
I have an activity defined as:
public class MyDemo extends Activity
{
@Override
public void onCreate( Bundle savedInstanceState )
{
super.onCreate( savedInstanceState );
setContentView( R.layout.main );
}
@Override
public boolean onTouchEvent(MotionEvent me)
{
Log.i(MyDemo motion, + me.getAction());
return false;
}
}
With this custom view in main.xml
?xml version=1.0 encoding=utf-8?
com.test.MyCustomView
xmlns:android=http://schemas.android.com/apk/res/android;
android:layout_width=wrap_content
android:layout_height=wrap_content /
MyCustomView.java contains
public class MyCustomView
extends FrameLayout
implements OnGestureListener
{
public MyTest( Context context, AttributeSet attrs )
{
super( context, attrs );
LayoutInflater.from( context ).inflate( R.layout.doofer, this,
true );
}
@Override
public boolean onTouchEvent(MotionEvent me)
{
Log.i(MyCustomView motion, + me.getAction());
return false;
}
}
And finally doofer.xml is
?xml version=1.0 encoding=utf-8?
FrameLayout xmlns:android=http://schemas.android.com/apk/res/
android
android:id=@+id/dooferFrame
android:layout_width=200dip
android:layout_height=200dip
android:background=#80ff
TextView
android:id=@+id/doofer
android:layout_width=fill_parent
android:layout_height=fill_parent /

So... looking at LogCat we can see the motion events that occur. The
MyDemo Activity logs down, up and move events perfectly as expected.
However, MyCustomView only logs down events!
Why aren't ACTION_UP and ACTION_DOWN Touch Events passed through to
custom views?
I need to handle the touch events in the custom view (not the
activity) because there are several custom views in the activity and
all of them need to respond individually to fling motions. Detecting
fling events in the activity wont tell me over which view the fling
event happened. So i would like to handle the touch events in the
custom view (its a better OO practice than handling it in the
Activity).
Any Clue?

Strange. According to the docs false means that the event has not
been handled: true if the event is consumed, else false
Changing it to true works though. Thanks.

[android-developers] CircularLayout for HorizontalScrollView ?
I am writing an day planner that requires fling gestures to horizontally scroll to the next previous day. Each day contains text and buttons and whatnot. I would like to use HorizontalScrollView for the scrolling. The problem is that a horizontal LinearLayout is bounded at creation. In other words, I have to decide how many days I want to be able to scroll through in advance. That will not work. What I would like is a CircularLayout to use as a child of HorizontalScrollView. The CircularLayout would have three frames: current, next previous. Every time the CircularLayout is scrolled the three frames are re-rendered to give the impression of an infinite list of views. Is there any way to do this? is there another way that will give me what I want? Thanks, Clark -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Android Bug: Time.parse3339 crashes BEFORE it throws a TimeFormatException!
Here is some code I write to parse a 3339 time that I get back from
Google's gData:
try
{
Log.d(setUpdated, newTime );
Time time = new Time();
if( time.parse3339( newTime ) )
{
this.mUpdated = time;
}
}
catch( android.util.TimeFormatException ex )
{
ex.printStackTrace();
}
Here is some of the log output from LogCat:
setUpdated 2010-01-07T20:26:29.000Z
setUpdated 2010-01-07T20:26:36.000Z
setUpdated 2010-01-07T20:26:22.000Z
setUpdated 2010-01-
Then it crashes because of a TimeFormatException. The times are
coming from the gData calendar API so it is surprising that it returns
a bad time in only one case. However, that is not the problem.
Notice that I said that it CRASHES because of a TimeFormatException,
not that it THROWS a TimeFormatException. I said that because it
doesnt actually throw the exception! If I put a breakpoint on the
stack trace line the debugger never gets there. if I put a Log.d
there it doesnt display. If i change the catch to an Exception it
still never gets there. However, dalvikvm clearly outputs the
TimeFormatException and its stack trace to LogCat. (I'd post it here
but you cant copy-paste from LogCat).
This leads me to believe that there is a bug in
android.text.format.Time.parse3339() where it crashes before it has
the opportunity to throw the exception it just logged!
Has anyone else seen this? This is using Android 2.0. Is it known
and fixed in 2.0.1? Is there a way to report this to the android
devs?

[android-developers] Re: Why is my eclipse up to date with 2.0.1 but no android tools appear in the UI?
Apparently this is a common issue with Windows 7 and eclipse plugins. Eclipse does not like having more than one plug in at a time on Windows 7. Doing so may or may not work depending on how astrological constellations align with the mating cycle of the Australian Gypsy Moth. The solution is to log in as admin and blow away C:\Users\admin \.eclipse directory. Eclipse will recreate it when you restart it. You then have to re-enter the plug-in url for android and update it. This time android will be the only plug in. Not even the ones that came with Eclipse will be there. This fixed it for me.

[android-developers] Re: Launching an external activity from a widget
Thanks a lot Mark, Dianne and Walter. We ended up having to call pendingIntent.send() before the call to remoteView.setOnClickPendingIntent() in the handleButtonAction() method. That works, although it seems like the remote view should be responsible for sending the pending intent. Thanks again!

Well, that certainly simplifies matters... :-) He just implemented an intent-filter in his manifest to listen for an action called com.poof.intent.action.MovieApp Does his intent-filter have anything else? For these sorts of things, I usually just have the action element in the filter and nothing else. You don't need a category or anything, and they can actually get in the way a bit. For example, if his intent-filter has a category, you'll need that category in your Intent as well, AFAIK. I changed my code to Intent intent = new Intent( com.poof.intent.action.MovieApp ); intent.putExtra(FILENAME, MOVIES[state.currentMovie].filename); PendingIntent pendingIntent = PendingIntent.getActivity( context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT ); remoteView.setOnClickPendingIntent( R.id.btnDoIt, pendingIntent ); And updated his apk on my emulator. The button still does nothing. Any ideas? Examples? Well, assuming his intent-filter is just the action, that should be fine. Are you seeing any warnings in LogCat? If Android can't find a match on the Intent, it'll toss out a warning, not an error. Also, you could toss together a scrap project and call a regular startActivity() in there on the Intent, to see if that launches. That'll tell you if your problem is in the Intent construction or in the app widget proper. In terms of an example, here's one where I am starting up the browser on a URL: Intent i=new Intent(Intent.ACTION_VIEW, Uri.parse(c.getString(1))); PendingIntent pi=PendingIntent.getActivity(this, 0, i, 0); updateViews.setOnClickPendingIntent(R.id.title, pi); updateViews.setOnClickPendingIntent(R.id.panel, pi); In this case, I am using the same PendingIntent on two views in the app widget, because the title itself (a TextView) is kinda thin and difficult to tap, so I have the panel (a layout) behind it also respond to a click to provide a larger target. Also, c.getString(1) is pulling a String URL value out of a Cursor. -- Mark Murphy (a Commons Guy)http://commonsware.com|http://twitter.com/commonsguy Android App Developer Training:http://commonsware.com/training -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Launching an external activity from a widget
I have written a widget that cycles through a series of movie poster images with next/prev buttons. This works. There is another button on the widget that needs to launch an external activity, sending it the name of the shown movie. The other activity is not in the same namespace, package or eclipse project as the widget. It is written by another developer and its apk is installed on my emulator. What code do I need to start up an external activity from a widget? I tried this in my handleButtonAction() method. Intent intent = new Intent( Intent.ACTION_VIEW ); intent.setClassName( context, com.poof.ExternalMovieApp ); intent.putExtra(FILENAME, MOVIES[state.currentMovie].filename); PendingIntent pendingIntent = PendingIntent.getActivity( context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT ); remoteView.setOnClickPendingIntent( R.id.btnDoIt, pendingIntent ); I tried it with and without the action parameter in the intent constructor. Either way, nothing happens when I press the button. Is this code wrong? Do I need to add the external activity to my manifest (how?)? Is there a better way to get the external activity's class name than hard coding it like this? Are there any online examples that do this sort of thing? All of the examples i've seen merely launch configuration apps that are in the same package as the widget.

[android-developers] How do I create a jar containing the .class files in bin?
I am making an API for my own use. It is an Android project in eclipse. An Android activity project in the same workspace uses it to do stuff. Or at least, thats the idea. The problem is that when i try to export the API as a jar that can be used by the activity the JAR wizard only shows me source files. It will not allow me to add .class files to the jar! It wont even show them. In the package explorer the bin directory is not there. However, it is there if you look at the file system. The clas files are built and in bin like I would expect. How do I create a jar containing the .class files in my API that can be used by another project? (Oddly, i had this working at one point but now it wont... even after recreating the project from scratch!)

[android-developers] CalendarService - ExceptionInInitializerError
I am trying to use the CalendarService in an android app to add events to my google calendar. I get a ExceptionInInitializerError when instantiating the class. CalendarService myService = new CalendarService( MyCalendar ); Is this not supported in android? If not then how do you do it? I also tried it by writing an xml request directly to http://www.google.com/calendar/feeds/... That returned an http success but no event showed up on my calendar. And yes, I have the INTERNET permission set. Any ideas? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Example Needed: a view containing a reference to its activity
But my activity never explicitly calls the view's constructor. The activity simply calls: setContentView( R.layout.main ); in its onCreate() method, and the custom view is specified in the main.xml. I think the constructor is called when the device is booted. Is there another way to set the content view explicity? On Oct 28, 1:48 pm, Mark Murphy mmur...@commonsware.com wrote: Would you have to use instanceof to find out if the context was the activity? At least once in development, to confirm that your View's Context is an Activity. If you're concerned about the Context's underlying type changing -- and it's not an unreasonable concern -- then you're better served holding your own reference to the Activity. That's fairly cheap, and if you require an Activity in the constructor, you eliminate all doubt. -- Mark Murphy (a Commons Guy)http://commonsware.com Android App Developer Books:http://commonsware.com/books.html --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Architecting a count down timer
Thanks a lot! Your suggestions greatly simplified my code. I changed
it so that the TimerView binds to the TimerService and communicates to
it directly through its ServiceConnection (just like in the sample
code). There is so much to the API I didnt know about that sample or
about the CountDownTimer! Thanks again.

Creating a custom View is certainly possible but probably way overkill
for this sort of app.
When the start button is pressed the TimerView broadcasts a START
intent containing the number of seconds. The TimerService contains a
BroadcastReceiver listening for the START intent.
Why not just call a method on the service object? You can get the
service object either by creating your own public static singleton or by
using the local binding pattern shown in the ApiDemos of your SDK.
When the
TimerService receives START it begins broadcasting a TICK intent
(containing the number of seconds remaining) every second until zero
is reached.
Why not just register a listener object with the service, that the
service calls periodically?
Broadcast Intents are broadcast to the device, not the app, and so are
much more expensive in terms of CPU time than merely calling a method.
They are also public, in the sense that any app can receive those
broadcasts.
public class TimerService extends Service
{
private int _seconds = 0;
private Handler _timerHandler;
�...@override
public void onCreate()
{
_timerHandler = new Handler( );
}
...
public class StartListener extends BroadcastReceiver
{
�...@override
public void onReceive(Context context, Intent intent)
{
_seconds = intent.getIntExtra( seconds, 0 );
_timerHandler.postAtTime( runTimer,
SystemClock.uptimeMillis() +
1000 );
}
I have never used a Handler in a Service, so I don't know how that
fares. As an alternative, you might use android.os.CountDownTimer, which
seems tailor-made for your scenario.
receiver android:name=TimerService$StartListener
intent-filter
action android:name=com.poof.timer.action.START/
/intent-filter
/receiver
For temporary broadcast receivers, use registerReceiver() in Java code,
not a manifest-registered receiver like you have here.
Look good so far? Well, it isnt. The problem is that it wont build
because, according to Eclipse, com.icd.timer.TimerService
$StartListener is enclosed, but not static. Its the same with
TickListener. I could simply make the StartReceiver and TickReceiver
classes static but that wont work because both of them need to set the
state of their containing objects.
How do I get around this?
Try getting rid of the public keyword and make them simply
package-private or private inner classes, after switching to using
registerReceiver(). If you switch to the listener pattern, the receivers
all become moot, anyway.
(Its my first android app).

[android-developers] Architecting a count down timer
I am writing a timer application that counts backward from a time and
notifies when the timer reaches zero. It is intended to allow the
user to start a timer that continues to tick and will notify them when
complete even after the activity is backgrounded. Also, it will show
the correct in-progress countdown after the activity is re-
foregrounded.
TimerActivity.onCreate() inflates the TimerView (allowing the user to
set the time and hit the start button) and starts the TimerService.
When the start button is pressed the TimerView broadcasts a START
intent containing the number of seconds. The TimerService contains a
BroadcastReceiver listening for the START intent. When the
TimerService receives START it begins broadcasting a TICK intent
(containing the number of seconds remaining) every second until zero
is reached.
The TimerService looks like this. The BroadastReceiver is inside of
the TimerService because it must set the TimerService's members.
public class TimerService extends Service
{
private int _seconds = 0;
private Handler _timerHandler;
@Override
public void onCreate()
{
_timerHandler = new Handler( );
}
...
public class StartListener extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent)
{
_seconds = intent.getIntExtra( seconds, 0 );
_timerHandler.postAtTime( runTimer,
SystemClock.uptimeMillis() +
1000 );
}
private Runnable runTimer = new Runnable()
{
public void run()
{
// Decrement the counter ==
if( _seconds 0 )
_seconds--;
// Broadcast the tick =
Intent intent = new Intent(TICK_ACTION);
intent.putExtra( seconds, _seconds );
sendBroadcast( intent );
// Schedule another tick? ==
if( _seconds 0 )
scheduleTick( this );
}
};
}
}
I would like the TimerView to be able to receive the TICK broadcasts
from the TimerService and update itself accordingly. So, something
like this...
public class TimerView extends FrameLayout
{
public TimerView(Context context, AttributeSet attrs, int defStyle)
{
super( context, attrs, defStyle );
LayoutInflater.from( context ).inflate( R.layout.timerview,
this,
true );
...
mStartButton = (ToggleButton)findViewById( R.id.Start );
mStartButton.setOnClickListener( new OnClickListener()
public void onClick(View view)
{
requestFocus();
Intent intent = new Intent(START_ACTION);
intent.putExtra( seconds, getTimeInSeconds()
);
Context context = this.getContext();
context.sendBroadcast( intent );
}
} );
}
public class TickListener extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent)
{
int seconds = intent.getIntExtra( seconds, 0 );
setTimeInSeconds( seconds ); // Sets the view to the
number of
seconds remaining
}
}
}
The application tag in the manifest contians this to tie it all
together
manifest xmlns:android=http://schemas.android.com/apk/res/android;
package=com.poof.timer
android:versionCode=1
android:versionName=1.0
