So you have a pre-populated database that you'd like included with the
application upon installation?

I'm not sure what the preferred solution is for this, but it might be
possible to accomplish this via a raw resource.

In general, a raw resource is a file that can be bundled with your
application and accessed via: R.raw.*

See: http://developer.android.com/guide/topics/resources/resources-i18n.html

I assume that you've already gotten SQLite to work in general.  If
not, I highly suggest the Notepad tutorial, which is a great primer:
http://developer.android.com/guide/tutorials/notepad/index.html

Hope this helps!

Re: [android-developers] Problem RemotableViewMethod while extending TextView

bostwick wrote:
 The included Chronometer widget doesn't quite have the functionality I
 wanted, so I copied its code into my own package. 

The source code to Android is not necessarily designed to be pulled out
and used in isolation elsewhere. Some classes will work that way (e.g.,
I have cloned AsyncTask and MatrixCursor), but others will not because
they have dependencies on other open-source-but-not-in-the-SDK classes
and methods.

 Looking through the android source, you can see stock widgets using
 the RemotableViewMethod all over the place, but for some reason, my
 code can't.

That is probably used by the firmware build process.

 So, my question is this: What can I do to enable the
 RemotableViewMethod annotation in my custom widgets?

Most likely, you can't.

 Is there
 something I should be doing differently in order to code custom
 widgets?

Well, your underlying problem didn't make it into your paste. You are
failing on a NullPointerException (line #42 of the paste), and you need
to track that down.

AFAIK, the RemotableViewMethod annotation will not affect you if you are
using a widget in an activity.

 I know that part of the problem is just my lack of experience with the
 Android SDK, and I don't fully understand what the RemoteViews class
 does or why it's needed, and the two sentence description in the API
 docs doesn't help much there. If someone could explain just the
 logistics of this class, that would also be helpful.

Mostly, in terms of the SDK, RemoteViews is used for app widgets --
those doodads you can put on the home screen. Since the home screen runs
as its own process, it can't execute your code. Instead, via
RemoteViews, you effectively serialize a bunch of UI operations that get
sent from your own process to the home screen for execution. UI widgets
(android.widget.*) that work with RemoteViews get the
@android.view.RemotableViewMethod to indicate what can and cannot be
used in this fashion, AFAICT.

Re: [android-developers] How to pass large amount of data during startActivityForResult

tomei.ninge...@gmail.com wrote:
 From one activity, I want to pass a lot of data (about 1MB of
 Strings).

No, you don't. You want 1MB of data to be available to multiple
activities. There is a very big difference; you do NOT want to be
copying 1MB of Strings.

 I tried sticking it in Intent.putExtra(ArrayListString), but if I
 put in too much data, I get FAILED BINDER TRANSACTION.

And, among other things, this would be copying 1MB of Strings once or twice.

 What's the easiest way? I don't want to publish a service, or use the
 file system. I really want a pipe that can write data from one end and
 read it from the other end.
 
 I can handle the case where the starter Activity dies while the
 startee activity is trying to read from the pipe.

Use a static data member.

For what it's worth, I had a similar issue.  I didn't get any error

But then I realized that I had not installed Java since installing

     the task from the caller and has nice hooks to do things like manage
     ProgressDialogs. and everything happens in the right thread
     automagically.

     adopt AsyncTask, see all problems like this go away.

     Hi, I have a weird problem on progress dialog:

     I have 2 views: Login View and say, Display View.

     In Login View, when I click the 'Login' button, a progress dialog is
     created (new ProgressDialog(...)), shown and stored in a variable
     'mProgressDialog'. After login, the dialog is dismissed and some
     information are displayed in Display View (Login View hides). Now I
     want to display another progress dialog when 'Update' button is
     clicked and when the update is done, dismiss the dialog and display
     new information. So I use:

     mProgressDialog = new ProgressDialog(...);

     to create a new progress dialog with new title and message. Show.

     Now the weird thing happens when the new dialog dismisses. The 
  program
     flashes the Display View for a blink and then shows the Login 
  View

     I tried to change the view etc. but same problem happens over and 
  over
     again. So I am thinking it might because one activity can only be
     assigned to ONE progress dialog and no matter how you re-create it 
  you
     still get the same progress dialog. And the dialog is linked to a
     certain view which will be shown automatically when the dialog
     dismisses.

     Please tell me I am wrong...

[android-developers] Re: Poll Screen On/Off state

2009-11-03 Thread gudujarlson

 Monitor the ACTION_SCREEN_OFF and ACTION_SCREEN_ON Intents, then. If
 your application starts based on a user action, then you know the screen
 is on at that point -- you don't need an API for that.

That occured to me, but I'm not confident that it would be reliable. I
don't like the idea of listening for 2 events, storing a status for
later use, and hoping that I never miss an event or start with the
screen off. One possible troublesome scenario occurs when the app
starts really slow for some reason and before the listener is
registered, the user turns the screen off.

Re: [android-developers] Re: Stable contact identity CONTENT_LOOKUP_URI

2009-11-03 Thread Dmitri Plotnikov

Hi Richard,

Lookup key is unique at any point in time.  It's not unique over time.

The anatomy of a lookup key is basically this.  If an aggregate contact has
three raw contacts with server-side IDs A, B and C, the lookup key
will effectively be  accountA/A.accountB/B.accountC/C

We don't attempt to find a contact with that exact lookup key.  We actually
parse it, find all those three raw contacts and infer the id of the new
contact ID, which will be the one containing the most of the original raw
contacts. In other words, even though the result is a bit unpredictable, the
user shouldn't be surprised by what they see.  The original contact had A, B
and C - now I am looking at something that has either A or B or C or a
couple of those or maybe A,B,C and D.

You are right that you should not use lookup keys to compare contact
identities to each other.  You can use the
ContactsContract.Contacts.lookupContact(resolver, lookupUri) method, which
will give you the current contact ID for your contact.  Be careful though -
between the moment you get it and the moment you use it the contact may
change.  Any kind of background sync could cause this change to happen.  I
would try to design the software in such a way that either doesn't need to
do this type of resolution or uses something even more robust than lookup
keys, e.g. raw contact IDs.

I hope this helps,
- Dmitri


On Tue, Nov 3, 2009 at 6:40 AM, jarkman jark...@gmail.com wrote:

 Oh - one more question:

 Am I right in thinking that the lookup URI is not itself a unique,
 stable identifier ? That is, the lookup URI for one contact may be
 different at different times.

 Right now, we store some contact row IDs in a table, along with per-
 contact settings of our own. We use a WHERE clause on the contact ID
 to pull out the settings for a particular contact.

 If we store lookup URIs in the table, and want to find some current
 contact in that table, we cannot do it by comparing lookup URIs
 directly, because the lookup URI for the target contact may have
 changed since we wrote the table. If we want to compare two lookup
 URIs to see if they refer to the same person, we need to look them
 both up in the contacts table and see if they have the same record ID
 right now. Is that right ?

 Thanks,

 Richard


 On Nov 2, 5:32 pm, Dmitri Plotnikov dplotni...@google.com wrote:
  Hi Richard,
 
  You are exactly right.  If you want a robust persistent reference to a
  contact, you now need to use the lookup URI.  Android itself uses lookup
  URIs for shortcuts, Quick Contact etc.  The main reason contact ID is
  volatile is that Android 2.0 has contact aggregation, both automatic and
  manual.  Let's say your app stored a long ID of a contact.  Then the user
  goes and manually joins the contact with some other contact. Now we have
 one
  contact where we used to have two - the stored long contact ID points
  nowhere.  However, the lookup key is more resilient.  It's a string
  concatenating identities of raw contacts.  Using that string, we can
 still
  track down a contact as it is joined with others or separated from them.
 
  There are two options available to you: you can store just the lookup
 key,
  which is a string id of a contact, or you can use both the lookup and the
  long id of a contact.  The latter will give you better performance, but
  functionally the long id is not required.  I would take this approach: if
  you need to bulk-process contacts, maintain both ids.  If your app works
  with a single contact per user action - you don't need to bother with the
  long id.

   That would be a substantial change in our code. So, before I rush off
   to do it, I'd love to find out if a contact row ID change is going to

   Any clues ?

 Alternatively, you can check the phone model variable:

 On my G1 phone, it gives me HTC DREAM
 For the emulator, it gives sdk.

[android-developers] ProgressDialog went back to the first view called it when dismiss()

2009-11-03 Thread Larry

Hi, I have a weird problem on progress dialog:

I have 2 views: Login View and say, Display View.

In Login View, when I click the 'Login' button, a progress dialog is
created (new ProgressDialog(...)), shown and stored in a variable
'mProgressDialog'. After login, the dialog is dismissed and some
information are displayed in Display View (Login View hides). Now I
want to display another progress dialog when 'Update' button is
clicked and when the update is done, dismiss the dialog and display
new information. So I use:

mProgressDialog = new ProgressDialog(...);

to create a new progress dialog with new title and message. Show.

Now the weird thing happens when the new dialog dismisses. The program
flashes the Display View for a blink and then shows the Login View

I tried to change the view etc. but same problem happens over and over
again. So I am thinking it might because one activity can only be
assigned to ONE progress dialog and no matter how you re-create it you
still get the same progress dialog. And the dialog is linked to a
certain view which will be shown automatically when the dialog
dismisses.

Please tell me I am wrong...

[android-developers] Timepicker appearances, the disabled state is ugly

It seems to be a fundamental problem with this build's handling of an

[android-developers] Documentation deficiencies.

2009-11-03 Thread Tim Hutt

Hi, this has been noted by many people previously, but I thought I'd
have a little rant about it. Simply put, the Android SDK documentation
is shockingly incomplete. I can't believe Google doesn't have the
resources to employ someone full-time to work on it. Here are just a
few examples:

1. You need to call ItemizedOverlay.populate() even if you have added
no items. This is mentioned no-where, and I've even seen people create
crazy work-arounds because they didn't know it.

2. populate() isn't explained at all well. Let's compare a few
function descriptions with what *I* would write:

ItemizedOverlay intro, current version:

A base class for an Overlay which consists of a list of OverlayItems.
This handles sorting north-to-south for drawing, creating span bounds,
drawing a marker for each point, and maintaining a focused item. It
also matches screen-taps to items, and dispatches Focus-change events
to an optional listener. 

My version:

ItemizedOverlay is an Overlay that allows you to easily draw small
collections of [OverlayItem]s on top of the map. Typically the items
will be some kind of pin or marker. A default [Drawable] to use can be
passed to the constructor, and individual [OverlayItem]s can have
specific [Drawable]s. This class handles sorting the items
north-to-south so that the overlap as expected, and drawing a marker
for each point. It also maintains a focused item, matches screen-taps
to items, and dispatches Focus-change events to an optional listener.
Typically it is subclassed and used as described below. See the
documentation for populate() and createItem() for further information
on how to specify the [OverlayItem]s. then I would give an example of
deriving a simple class from ItemizedOverlay, but I'm not paid to
write this so meh

ItemizedOverlay.populate(), current version:

Utility method to perform all processing on a new ItemizedOverlay.
Subclasses provide Items through the createItem(int) method. The
subclass should call this as soon as it has data [note that this is
*wrong*!], before anything else gets called.

My version:

ItemizedOverlay maintains an internal cache of [OverlayItem]s in
order to draw them efficiently. This function must be called in order
to populate the internal cache. Note that it must be called before the
draw() method is even if you have added no items. When it is called it
first uses ItemizedOverlay.size() to determine how many [OverlayItem]s
there are to draw. You must override this method in your subclass.
Once the number of items has been determined it calls
ItemizedOverlay.createItem(int i) for i=0 to size() in order to
retrieve each [OverlayItem]. These items are then sorted from north to
south to facilitate drawing. Whenever you change the items to be drawn
you must call populate() in order to update the cache.

Actually I've just noted that that description isn't quite true and
has caused a bug in my program - size() is apparently only ever called
once. This is pretty stupid but hey, my point stands.

3. At http://developmentality.net/ there is a note about how
setMarker() doesn't work unless you set the bounds on the drawable.
This should clearly be mentioned in the documentation.
4. fill_parent, wrap_content, gravity and so on aren't adequately
explained *at all*.
5. Not a documentation issue, but boundCenterBottom() should be really
be public.
6. I strongly encourage you to look at the documentatio for
ProgressDialog. It is truly shocking:
http://developer.android.com/reference/android/app/ProgressDialog.html#getMax()

I know there are a lot of classes, but *really*.

7. There are so many classes where the documentation is the type that
I would write *to myself* as I was writing the code. e.g. Bundle is
described as A mapping from String values to various Parcelable
types.. That's it. Helpful.

This mailing list is clearly too high volume for anyone from Google to
read, but I feel better for having ranted. Back me up here people.

[android-developers] Re: Poll Screen On/Off state

2009-11-03 Thread Carter

You can't poll screen on/off state.  The best you can do is to
register a BroadcastReceiver, and wait for an Intent to come along.
Until that first Intent is received, you'll have no idea what the
screen state is.

 What does the user being idle have to do with anything here? If there is
 no work to be done, there is no work to be done, so stop your service
 and wake it up after some time to see if there is new work to be done.

  What am I to do?

 Don't worry about user idleness. Just stop your service and get it out
 of RAM when you have no work to do. Restart the service after a period
 of time, or based on some other event trigger, to see if there is new
 work to do.

  In general, I find the lack of support for polling system state
  properties (e.g. screen state, power state, signal strength) in
  Android to be annoying. It's cool that one can listen for changes in
  system state rather than constantly polling for them, but one still
  needs to know the current state of the property at the time the
  listener is registered. Am I missing something fundamental?

 Power is available on demand via a sticky Intent.

 WiFi signal strength is available on demand via WifiManager.

 GSM/CDMA signal strength is available on demand from TelephonyManager.

[android-developers] Re: How to add file .sqlite extension to our project

(I'm reposting this response because I think I accidentally replied
only to the original author.)

Archana,

So you have a pre-populated database that you'd like included with the
application upon installation?

I'm not sure what the preferred solution is for this, but it might be
possible to accomplish this via a raw resource.

In general, a raw resource is a file that can be bundled with your
application and accessed via: R.raw.*

See: http://developer.android.com/guide/topics/resources/resources-i18n.html

I assume that you've already gotten SQLite to work in general.  If
not, I highly suggest the Notepad tutorial, which is a great primer:
http://developer.android.com/guide/tutorials/notepad/index.html

Hope this helps!

[android-developers] Poll Screen On/Off state

2009-11-03 Thread gudujarlson


I have an app that runs in the background indefinitely provided there
is work to be done. I want the app to go to sleep if there is no work
to be done and the user is idle. The second part has me stumped. On
Windows Mobile I was able to poll the power state to determine user
idleness. On BlackBerry I was able to poll the device idle time.
However, there does not appear to be a way to determine user idleness
on Android.

Instead of polling for user idleness directly, I thought I might be
able to use the on/off state of the screen. There are 2 intents
ACTION_SCREEN_OFF and ACTION_SCREEN_ON and I was able to setup a
listener for these (BroadcastReceiver). The problem is that I do not
know how to determine the current state of the screen at the time I
register the listener, therefore I have to wait until the next screen
on/off change to know anything. The docs speak of some intents that
are sticky and thus will allow the current state to be determined,
but the screen events do not appear to have that property. What am I
to do?

In general, I find the lack of support for polling system state
properties (e.g. screen state, power state, signal strength) in
Android to be annoying. It's cool that one can listen for changes in
system state rather than constantly polling for them, but one still
needs to know the current state of the property at the time the
listener is registered. Am I missing something fundamental?

 1.start the camera in application and pass the preview data to native

This is the only 'supported' way. Apparently there is a bug with the
camera callback that creates a new massive object for every frame.
Since java is shite and garbage collected this slows this way down
even before you copy all the data through JNI.

 2.Start the camera directly in native layer and use it. So JNI will
 come less into picture. and not much resource loading also.But dont
 want to take any risk by using the lower layer code which may change
 in future.

Yeah this would be ideal, but not supported yet, if ever.

 Login View shows up.

   seriously though i would advise anyone doing anything with threads
   and progress dialogs to use AsyncTask. this wonderful class decouples
   the task from the caller and has nice hooks to do things like manage
   ProgressDialogs. and everything happens in the right thread
   automagically.

   adopt AsyncTask, see all problems like this go away.

   Hi, I have a weird problem on progress dialog:

   I have 2 views: Login View and say, Display View.

   In Login View, when I click the 'Login' button, a progress dialog is
   created (new ProgressDialog(...)), shown and stored in a variable
   'mProgressDialog'. After login, the dialog is dismissed and some
   information are displayed in Display View (Login View hides). Now I
   want to display another progress dialog when 'Update' button is
   clicked and when the update is done, dismiss the dialog and display
   new information. So I use:

   mProgressDialog = new ProgressDialog(...);

   to create a new progress dialog with new title and message. Show.

   Now the weird thing happens when the new dialog dismisses. The program
   flashes the Display View for a blink and then shows the Login View

   I tried to change the view etc. but same problem happens over and over
   again. So I am thinking it might because one activity can only be
   assigned to ONE progress dialog and no matter how you re-create it you
   still get the same progress dialog. And the dialog is linked to a
   certain view which will be shown automatically when the dialog
   dismisses.

   Please tell me I am wrong...

 Hi, this has been noted by many people previously, but I thought I'd
 have a little rant about it. Simply put, the Android SDK documentation
 is shockingly incomplete.

I agree, the Android API docs are horribly inadequate.  Why aren't
there examples _with the docs_?  I don't want to go digging through
some random apps hoping to find an example of what I need.  I want to
see practical examples on the same page with the docs.  With their 30%
take on all our app sales, you'd think they would want us to be able
to figure stuff out easier.

Last night I wasted two hours beating my head against the wall trying
to figure out why a market:// url wouldn't work in the emulator.  I
finally figured it out when I tried it on my phone and it worked.
That's when I realized the emulator doesn't have a marketplace app and
obviously doesn't understand market:// urls.

[android-developers] dummy Binder/C++ service

2009-11-03 Thread Michael Richardson

I wrote a dummy HelloWorld service and client.
It uses Binder for IPC.  For some this is likely duh, but it did take
me several days of puzzling to work things out.  I think some of the
problem is that there is some dead code in IMediaPlayerClient.cpp, which
I was using as my guide.

I'm convinced that it should be possible to see the services from Java
Binder/ServiceManager code, and avoid a layer of JNI (and thus an NDK
invocation) between a Java application and a C++ service, but I didn't
manage that.  The bird droppings in the src/org/credil/...*.java are my
attempts, ignore them, or better yet, fix them.

Push the three pieces generated: libhelloworldservice.so (to
/system/lib), and helloworldservice, and helloworldclient to /data.
adb shell
cd /data
./helloworldservice 
./helloworldclient

I hope that this code will help others from scratching their head a lot.

   https://review.source.android.com/#change,12454
is one suggestion I have to make other writers of code like this easier.

Probably I'm posting to the wrong mailing list, sorry.
I can not keep up with these mailing lists.

My code is at:
 http://github.com/mcr/Android-HelloWorldService

I'm not sure it is published in the SDK.  There was a round of simplication

You can directly draw onto surface bound with canvas passed in in your
draw handler. You don't have to always first draw into bitmap then
copy from bitmap to surface.

In fact, no matter what strategy you use you have not really drawn
onto screen framebuffer directly, the last action is composing done by
surfaceflinger service which sit in native layer but it only export
limited method you can access. I think directly accessing /dev/
graphics/fb0 is not recommand by android platform.

[android-developers] Re: java.lang.OutOfMemoryError after orientation changed

2009-11-03 Thread Mihai Fonoage

When an orientation occurs, your activity is being destroyed, and a
new instance is created. The problem is that some references are still
kept in memory.

Some useful resources to read: Avoiding memory leaks (http://android-
developers.blogspot.com/2009/01/avoiding-memory-leaks.html) and
Faster screen orientation change (http://android-
developers.blogspot.com/2009/02/faster-screen-orientation-

I had similar issues when loading bitmaps, and screen orientation
changes would through an out of memory error almost every time at some
point. The above links helped in solving the issue.

[android-developers] Re: ListActivity and SQLiteDB problem - can't refresh list

Well, you get 100 cool points for knowing that you should use
AsyncTask, to let the query run in the background.

It seems odd that the list populating makes the UI stuck for a while.
Can you give us an estimate of how many rows and columns are in your
list, and how long the UI is stuck while it's being populated?

 Hi,

 What is the best way to display a database queries results on the

 background and I also need to be able to make different queries and
 refresh the screen according to the query result.

 I am using the ListActivity class with a SimpleCursorAdapter in order
 to display the db queries result on the screen.
 At the moment, I am doing the db queries at the background using
 AsyncTask, when getting the results I want the list to be updated
 immediately, but I can't find a good way to do it.
 It worked only when I used the changeCursor(cursor) function to set
 the adapter to a new cursor with the new results. But I don't think
 this is a good solution since it seems to stuck the UI for a while.
 I also found some posts about notifyDataSetChanged() but I am not sure
 if/how/when I should be using it with a SimpleCursorAdapter to make
 the view refresh.

 Can anyone tell what I am doing wrong? Or give a code example or link

[android-developers] Problem running a compiled/packaged-with-v1.6 application on v1.5

2009-11-03 Thread Armond Avanes

Hi Guys,

I have an application which is based Android 1.5 but for enabling different
screen types support I have to compile and package it with v1.6. When I
install and run the resulted APK on my 1.5 emulator, everything works fine
except that Preferences activity crashes every time I launch it!

config blocks from AndroidManifest.xml and compile/package it with 1.5,
everything works just fine!!

2009-11-03 Thread Mihai Fonoage

Hi,

I have tried to extend the GridLayout class (http://code.google.com/p/
apps-for-android/source/browse/trunk/Photostream/src/com/google/
android/photostream/GridLayout.java) so as to make it scrollable, but
with no success. In this regard, I tried initializing the scrollbars
inside the GridLayout constructor but I get an unsupported operation
exception saying Can't convert to dimension: type=0x10. In addition,
in the xml layout file that uses the GridLayout class, I tried placing
the FrameLayout (which has the GridLayout) inside a ScrollView but
that causes the GridLayout cannot have UNSPECIFIED dimensions error
message to be shown.

I initially was using a GridView with an adapter, but I never got it
to work 'smoothly'. When I changed the code and tried to use the
addView(View view) method, the method is not supported, since it is
encouraged the use of an adapter.

Has anybody used the GridLayout class successfully with scrolling
capabilities, or know how to implement them?

Many thanks,
Mihai Fonoage

 Hello,

 I am making an app that utilizes the BlutoothSocket API and am trying

 I do not see how I set the baud rate for the connection, how would I
 set it?

You cannot set the SPP baud rate with the current API.

[android-developers] Re: Provide a database packaged with the .APK file or host it separately on a website?

I've seen 3-4 different people ask some variation of this question in
these forums.  It seems like a very common question/need.
I'd like to see this specific topic addressed in part of the Dev
Guide, with various uses cases and proper solutions.

Pankaj, regarding your specific application:

Approach 2 sounds more sensible because the application is decoupled
from the data.
You could change the data without affecting the application, and vice
versa.
You could even take this modular approach a step further and allow
installation of pluggable, multiple databases.
For example, maybe db1 has Bible verses, db2 has Chinese fortunes, db3
has funny movie quotes, etc.
People could choose to install only the database(s) that they care
about.
(With approach 1, you would have to include all databases in the apk
file, which could become cumbersome.)

My two cents.  :)

wrote:
 Here is some background about my app:

 I am developing an Android app that will display a random quote or
 verse to the user. For this I am using an SQLite database. The size of
 the DB would be approximately 5K to 10K records, possibly increasing
 to upto 1M in later versions as new quotes and verses are added. Thus
 the user would need to update the DB as and when newer versions are of
 the app or DB are released.

 After reading through some forums online, there seem to be two
 feasible ways I could provide the DB:
 1.  Bundle it along with the .APK file of the app, or
 2.  Upload it to my app's website from where users will have to
 download it

 I want to know which method would be better (if there is yet another
 approach other than these, please do let me know).

 After pondering this problem for some time, I have these thoughts
 regarding the above approaches:

 Approach 1:
 Users will obtain the DB along with the app, and won't have to
 download it separately. Installation would thereby be easier. But,
 users will have to reinstall the app every time there is a new version
 of the DB. Also, if the DB is large, it will make the installable too
 cumbersome.

 Approach 2:
 Users will have to download the full DB from the website (although I
 can provide a small, sample version of the DB via Approach 1). But,
 the installer will be simpler and smaller in size. Also, I would be
 able to provide future versions of the DB easily for those who might
 not want newer versions of the app.

 Could you please tell me from a technical and an administrative
 standpoint which approach would be the better one and why?

 If there is a third or fourth approach better than either of these,
 please let me know.

 Thank you!

[android-developers] Re: Poll Screen On/Off state

2009-11-03 Thread gudujarlson

 What does the user being idle have to do with anything here? If there is
 no work to be done, there is no work to be done, so stop your service
 and wake it up after some time to see if there is new work to be done.

Well, I simplified the situation in an attempt to make my post
succinct. The app runs in the background and records information
including the device's location, but it also has a user interface.
What I want to prevent is draining the user's battery when they go
inside where there is no GPS signal and forget to turn off the app.
There is no point in running when there is no GPS fix and the user is
not watching the display. However, if the user is interacting with the
app, I want it to continue to run regardless of the lack of a GPS fix,
because useful information is still displayed and that information
requires continuous background processing.

 Power is available on demand via a sticky Intent.

The power state information that would be useful is not available as
far as I know. Windows Mobile has different power states such as ON,
OFF, and USERIDLE. I have not found the equivalent in Android.

 WiFi signal strength is available on demand via WifiManager.

I don't need this currently.

 GSM/CDMA signal strength is available on demand from TelephonyManager.

As far as I know, you cannot poll for signal strength and the event is
only triggered when the signal strength changes by quite a large
amount. Additionally. the event stops being raised when the screen
turns off. There is a poll function in the service (I looked through
the source), but it is not exposed in the SDK. There is a open feature
request related to this.

 In my application i want to pass the camera data to native layer. what

 I know it can be done 2 ways.

 1.start the camera in application and pass the preview data to native

 This is the only 'supported' way. Apparently there is a bug with the
 camera callback that creates a new massive object for every frame.
 Since java is shite and garbage collected this slows this way down
 even before you copy all the data through JNI.

Well, it's not a bug, it's just how Java works.
It certainly does suck.

 2.Start the camera directly in native layer and use it. So JNI will
 come less into picture. and not much resource loading also.But dont
 want to take any risk by using the lower layer code which may change
 in future.
 
 Yeah this would be ideal, but not supported yet, if ever.

We tried to get opencore to do this for us, and we failed.

We never even got opencore's extensive debugging to turn on while trying 
to figure out how things work, and after some person-weeks of effort, we 
  understood enough about opencore that we can use it as a library, but 
not via MediaService.

We are now writing our own service that opens the camera hardware 
directly, and runs as a service.  I do not think a lot of things will 
happen to this layer, except that it will not be available anymore.
We tried to chmod the camera devices so that it could be a non-root 
service, but there is more to it than that, so for now, it's a root 
service.

 Followed the instructions 
 inhttp://developer.android.com/sdk/adding-components.htmlfor adding 2.0 as

 It didn't work. Not by a long shot. Instead, it got partway through and then
 said that C:\android-sdk-windows-1.6_r1\temp\DocPackage.new01 couldn't be
 copied because of a lock, and similarly for PlatformPackage.new01.

 It said to shut down running programs, but the only program running was
 Eclipse, which was needed to do the upgrade.

 The cancel button was disabled, and the close box didn't work. Shutting down
 Eclipse killed it, but left C:\android-sdk-windows-1.6_r1 in a corrupted
 state. Restarting Eclipse showed the Android projects with errors, no SDK,
 and a disabled Android SDK and AVD Manager (which means no ability to rerun
 the install).

 Shutting down Eclipse, renaming the corrupted SDK directory, unzipping 1.6
 again into C:, and restarting Eclipse made it as if nothing had ever
 happened, which is good. But it is not possible to complete the install from
 Eclipse, which is bad.

 The dialog says:

[android-developers] Re: how to delete contact list and email from device

Why in the heck would anyone want an app that deletes all their

I hope you realize that when people try to install your app, they're
going to get a big fat warning when they install your program, saying
that your app will have permissions to delete their contacts.  So if
you are trying to be malicious, it's not going to work.  :)

By the way, my response above should give you a hint as to the

[android-developers] Re: Intents and navigating the GUI

Don't create a new intent for the main GUI.  Just call finish()
instead.

Also, if you want your main menu Activity to detect this event and do
anything special when it comes back to it, it can override
onActivityResult().

I'm leaving out some details such as howto return a result
(RESULT_OK), how to pass a Bundle on info back to the main menu if
desired, etc.

But if you do the Notepad tutorial, it teaches this concept well:
http://developer.android.com/guide/tutorials/notepad/index.html

Hope this helps!

 So far in my new selected GUI i create a new intent for the main GUI,
 but this looses all saved settings Sure this isn't the right way
 of doing it?

You can use the header file android/log.h in NDK, and link to

And you can find the details in the document of NDK
($NDK_ROOT)/docs/STABLE-APIS.TXT).

  It's basically just some new APIs on MotionEvent:

  gray, so
  they should be easy to see. :)

  Or  here is the API diff report:

 http://developer.android.com/sdk/api_diff/5/changes.html

   http://developer.android.com/sdk/api_diff/5/changes.htmlI see 
  that I
  didn't get around to writing documentation in MotionEvent on the way
 multi-touchworks; sorry about that.  Basically there are new actions 
 that
  tell you when additional fingers go down and up, and each 
  MotionEvent you
  receive allows you to query for the number of pointers in the event 
  as well
  as the x, y, size, and pressure of each of those points (and the 
  historical
  data for all those points as well if you want to collect all data 
  since the
  last motion event you received).

  So it should be pretty straight-forward.  The main thing to watch 
  out for is
  the difference between the index in the current event for a 
  pointer's data
  vs. the pointer ID for that pointer:

 http://developer.android.com/reference/android/view/MotionEvent.html#...

  http://developer.android.com/reference/android/view/MotionEvent.html#...The
  pointer ID allows you to keep track of the individual fingers across
  multiple motion events.  For example, if the user touches finger 1, 
  then
  finger 2, then releases 1, then touches 1 again, you would see:

  Finger 1 down: MotionEvent ACTION_DOWN with one pointer, whose ID 
  is 0.

  Finger 2 down: MotionEvent ACTION_POINTER_2_DOWN with two pointers, 
  whose
  IDs are 0 and 1.

  Finger 1 up: MotionEvent ACTION_POINTER_1_UP with one pointer, 
  whose ID is
  1.

  Finger 1 down: MotionEvent ACTION_POINTER_1_DOWN with two pointers, 
  whose
  IDs are 0 and 1.

  Finger 1 up: MotionEvent ACTION_POINTER_1_UP with one pointer, 
  whose ID is
  1.

  Finger 2 up: MotionEvent ACTION_UP with one pointer, whose ID is 1.

  (And inspite of what the update documentation says, the API allows 
  for an
  arbitrary number of fingers, not just 3.  I just happened to define
  convenience constants for the first 3 finger down/up actions, but 
  given
  their weird naming as seen above and the finger ID mask is actually 
  255, it
  is perhaps best just to ignore those constants. :p)

[android-developers] Trap in TabHost when AsyncTask delays setContentView at activity startup

2009-11-03 Thread Lee Laborczfalvi

I've got a tab host activity started from a home screen shortcut.
When my application starts it downloads information from a server
using an AsyncTask. In the onPostExecute method of the AsyncTask I
call setContentView to display the TabHost.

When I start the homescreen shortcut by tapping on the shortcut using
my finger everything works as expected, I download the information
from the server and display the TabHost with the information in the
tabs.

However starting the application by navigating to the shortcut with
the mouse wheel and then clicking on the shortcut with the mouse wheel
leads to a trap in the framework code as soon as my application
starts.  The stack trace is below:

Looking at the code for the TabHost class I see the following code at
the point where the trap occurs

public void onTouchModeChanged(boolean isInTouchMode) {
if (!isInTouchMode) {
// leaving touch mode.. if nothing has focus, let's give it to
// the indicator of the current tab
TRAP ON THIS LINE  if (!mCurrentView.hasFocus() ||
mCurrentView.isFocused()) {

mTabWidget.getChildTabViewAt(mCurrentTab).requestFocus();
}
}
}

This looks like a simple fix since mCurrentView is null at the time
that this method is called - can this issue be addressed? Does anyone
know of any workarounds?

Thanks
Lee

I believe you'll want to register a URI pattern that your application
handles.  You can look for content provider samples for that.  Then on
your own page display a link that matches that URI pattern.  You still
depend on the user clicking the link.

You can google for how people link to their market listing to get an
example of what people put on their webpages to load an applicaiton.

[android-developers] Re: Provide a database packaged with the .APK file or host it separately on a website?

2009-11-03 Thread westmeadboy

Have a look at ColorDict for a third approach (the middle path!).

On Oct 29, 3:34 pm, Pankaj Godbole [Andruid] panka...@gmail.com
wrote:
 Here is some background about my app:

 I am developing an Android app that will display a random quote or
 verse to the user. For this I am using an SQLite database. The size of
 the DB would be approximately 5K to 10K records, possibly increasing
 to upto 1M in later versions as new quotes and verses are added. Thus
 the user would need to update the DB as and when newer versions are of
 the app or DB are released.

 After reading through some forums online, there seem to be two
 feasible ways I could provide the DB:
 1.  Bundle it along with the .APK file of the app, or
 2.  Upload it to my app's website from where users will have to
 download it

 I want to know which method would be better (if there is yet another
 approach other than these, please do let me know).

 After pondering this problem for some time, I have these thoughts
 regarding the above approaches:

 Approach 1:
 Users will obtain the DB along with the app, and won't have to
 download it separately. Installation would thereby be easier. But,
 users will have to reinstall the app every time there is a new version
 of the DB. Also, if the DB is large, it will make the installable too
 cumbersome.

 Approach 2:
 Users will have to download the full DB from the website (although I
 can provide a small, sample version of the DB via Approach 1). But,
 the installer will be simpler and smaller in size. Also, I would be
 able to provide future versions of the DB easily for those who might
 not want newer versions of the app.

 Could you please tell me from a technical and an administrative
 standpoint which approach would be the better one and why?

 If there is a third or fourth approach better than either of these,
 please let me know.

 Thank you!

[android-developers] Set selected ringtone as device's default ringtone

2009-11-03 Thread kapil

I want to set selected ringtone as device's default ringtone.

As per my findings, we can use
ContentUris.withAppendedId
(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,id)  method to append the
selected ringtone id to content uri and then saving it in database
through ContentValues and System settings.

But i can't figure out what id to append.The id seems to be the id of
elements in hash table as MediaStore saves the audio in such form. Is
it so..?..How can i get the Id of hash table elements?

can play it like a flute/ocarina.  You blow into the mic and use
multi-touch to press a combination of holes to play different sounds.

I'm thinking about writing a *similar* app for Android, except it's a
*trumpet* instead of a flute.  My idea is:
* The screen shows three circles in a line, which represent the three
trumpet valves.
* Touching a circle represents holding down a valve.
* Blowing into the mic represents blowing into the trumpet.
* Note: On a real trumpet, the note pitch depends not only on the
valve combination, but also on the lip vibrations.  (Otherwise there
would only be 7-8 possible notes.)
* I'm thinking that the angle (elevation) of the phone could represent
different pitches.  So, if you elevate the phone up, you'll play a
higher note, for example.

The 4 technical aspects that I'd like to verify are:

1. What is the most sensible way to detect blowing into the
microphone?  My current plan is to do AudioRecord.read() and manually
examine the audio buffer data to check for sufficiently high amplitude
(volume).  I think this will be pretty easy, but just wanted to check
whether there's another better way to do this.

2. Is it possible to record and play at the same time?  I need to
record blowing into the mic and playing sound at the same time.

3. For checking elevation angle, I assume I should use SensorManager.
I assume that I want to use getInclination(), but I think I might also
need getRotationMatrix() or getOrientation().  Seems pretty easy, but
does anyone know of any examples I could look at?

4. For detecting which valves are pressed down, I assume that it's
feasible to use the multi-touch feature.  However, I have a G1 phone.
Is it possible to get multi-touch to work with the G1 phone somehow?
(This question probably deserves its own thread!)

I'm not going to ask about how to program multi-touch because there's
a good discussion of the technical features at:
http://groups.google.com/group/android-developers/browse_thread/thread/962b1a27a31e450d

Anyway, your input is highly welcome, as well as any other suggestions
you might have for this app.  (By the way, I might do other
instruments too, besides, trumpet, but I figure that if I can get
trumpet to work, I can get any other instrument to work.)

  Alternatively, you can check the phone model variable:

  On my G1 phone, it gives me HTC DREAM
  For the emulator, it gives sdk.
 
  I don't know what method is preferred by google, but it feels more

 That's only because it doesn't happen to currently be implemented in the

[android-developers] What is the Sprint Hero AppWidget problem?

2009-11-03 Thread btm...@gmail.com

Hello all,

I wrote a widget that has been working fine for most folks. However, I
started getting bug reports about how the widget would be blank on
reboot (not receive an update?), and it seemed that the Sprint Hero
continually came up. I thought I was crazy but I'm finding that other
people are having the same problems:

Searching Google for sprint hero appwidget problems yields:

Added warning about the problem on the Sprint Hero device: On the
Sprint Hero (HTC ROM v1.29.xxx) the AppWidget API is broken in such a
way that it won't ...

More specific blog post that mentions it but doesn't explain the
problem:

http://koxx3.wordpress.com/2009/10/22/htc-hero-sprint-bug/

I found the reason : HTC changed the Android widget management at
startup !
I hope they will fix it in a new ROM release, but I’d like to find a
solution to bypass this problem.
EDIT 28/10/2009 : problem solve for ‘Pure calendar’ with new option.

I e-mailed the author in hopes of getting an answer, but I haven't
received any response. Does anybody with a Sprint Hero know what the
problem is?

Thank you,
-Brian

The third argument isn't a pid, it's a process name, which is fed to

If you instead do:

Re: [android-developers] Viewing logs on native android

Oh, sure, you still can use logcat to logging for native android device.
Just choose your device in DDMS for logging.

if you want to logging just for App, the NDK is not necessary.

[android-developers] Re: Widget Layout Frustration

Evan,

I am also struggling with this same problem. It's mystifying because
so many widgets seem to have this look and yet I find it hard to
believe that all the developers painstakingly did it by hand.

Can you post a screenshot of what you have? In what way is yours just
a couple of pixels off?

Also, did you make that text_border file yourself? (I assume it is a
ninepatch...?) I scanned the SDK for *.9.png and found several
ninepatches that were similar but none that looked exactly right.
(Here's an example of how mine looks with the Toast ninepatch:
http://screencast.com/t/zEyDZr8fnI) It sure seems like if we found the
right ninepatch image we'd just have to add the faint shadow to the
text and then we'd be home free.

[android-developers] building for 1.5 using 2.0...

2009-11-03 Thread sdphil

i need my app to support 1.5 and above.

i noticed that if I create my build.xml file using --

c:\tools\android\2.0r3\tools\android update project --name MyProject --
path C:\MyProject --target 2

it complains about my resource directory names res/drawable-hdpi, res/
drawable-ldpi, etc...  res/layout-large, etc... saying invalid
resource directory name.

If I use 1.6r1 tool set
c:\tools\android\1.6r1\tools\android update project --name MyProject --
path C:\MyProject --target 2

Everything works fine.

If I use target 3 (1.6 and above)
c:\tools\android\2.0r3\tools\android update project --name MyProject --
path C:\MyProject --target 3

Everything works fine.

So, do I basically *have* to use 1.6r1 to build for 1.5?  And does
that mean that those special directory names will only work on 1.6 and
above?

[android-developers] Re: Problem RemotableViewMethod while extending TextView

2009-11-03 Thread bostwick

I managed to figure it out. You were right in that it didn't have
anything to do with RemoteViews or RemotableViewMethod.

Instead, my problem was that in my onClick method for my start button,
I was using the variable mChronometer, which was null, and so threw an
exception.

The bug was located in the onCreate() method of my activity.
Specifically, I had:

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.d(TAG, onCreate());

mChronometer = (Chronometer)findViewById(R.id.Chronometer);
mStartStop = (Button)findViewById(R.id.StartStopButton);
mResetLap = (Button)findViewById(R.id.ResetLapButton);

setContentView(R.layout.stopwatch);
}

But android didn't like this. findViewById() doesn't work correctly
unless it's called after setContentView(), so it was returning null
for all my fields and giving me the error.

Easy fix, just move setContentView() up, like so:

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.d(TAG, onCreate());

setContentView(R.layout.stopwatch);

mChronometer = (Chronometer)findViewById(R.id.Chronometer);
mStartStop = (Button)findViewById(R.id.StartStopButton);
mResetLap = (Button)findViewById(R.id.ResetLapButton);
}


Thanks for your help!

  The included Chronometer widget doesn't quite have the functionality I

 The source code to Android is not necessarily designed to be pulled out
 and used in isolation elsewhere. Some classes will work that way (e.g.,
 I have cloned AsyncTask and MatrixCursor), but others will not because
 they have dependencies on other open-source-but-not-in-the-SDK classes
 and methods.

  Looking through the android source, you can see stock widgets using
  theRemotableViewMethodall over the place, but for some reason, my
  code can't.

 That is probably used by the firmware build process.

  So, my question is this: What can I do to enable the
 RemotableViewMethodannotation in my custom widgets?

 Most likely, you can't.

  Is there
  something I should be doing differently in order to code custom
  widgets?

 Well, your underlying problem didn't make it into your paste. You are
 failing on a NullPointerException (line #42 of the paste), and you need
 to track that down.

 AFAIK, theRemotableViewMethodannotation will not affect you if you are
 using a widget in an activity.

  I know that part of the problem is just my lack of experience with the
  Android SDK, and I don't fully understand what the RemoteViews class
  does or why it's needed, and the two sentence description in the API
  docs doesn't help much there. If someone could explain just the
  logistics of this class, that would also be helpful.

 Mostly, in terms of the SDK, RemoteViews is used for app widgets --
 those doodads you can put on the home screen. Since the home screen runs
 as its own process, it can't execute your code. Instead, via
 RemoteViews, you effectively serialize a bunch of UI operations that get
 sent from your own process to the home screen for execution. UI widgets
 (android.widget.*) that work with RemoteViews get the
 @android.view.RemotableViewMethodto indicate what can and cannot be
 used in this fashion, AFAICT.

under LinearLayout one gravity is there and under Misc LayoutGravity
is there.

What is the difference between these two?

How to set the layout gravity of a linear layout  from code?


Thanks

Gopu

Re: [android-developers] Difference between Linearlayout's Gravity and LayoutGravity ?

2009-11-03 Thread Romain Guy

gravity = setting the gravity of the content of the view
layout_gravity = setting the gravity of the view inside its parent

Re: [android-developers] Re: text animation

2009-11-03 Thread Anh Khoa Nguyen Pham

Hi Saurav Mukherjee,

Thank a lot for your replying,
In your example, you move TextView object from center to left side of
screen. It means that when TextView has relative long content , it will look
not cool.
Do you know marquee property of TextView when we focus on this, don't you? I
want my text displayed symbol by symbol from right side screen to left side
screen ,and after the some symbols disappear in left side screen, they will
appear again at right side screen.
For example:
At begin time, screen display:
  S
After some miliseconds
Sa
.
  Saur
.
Saura
.
   Saurav
.
  Saurav 
.
Saurav M
  . . . . . . . .
  . . . . . . . .
  . . . . . . . .
  . . . . . . . .
.   Saurav
Mukherjee   
.   aurav
Mukherjee 
.   urav
Mukherjee   
.   rav
Mukherjee 
.   av
MukherjeeS
.   v
MukherjeeSa
.   
MukherjeeSau


Hope you understand clearly my problem and help me to solve that.
Can it be solved by animation?

Anyway, thank you again!

 Animation mAnimation;
 TextView mTextView;
 LinearLayout mLayout;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 mLayout = new LinearLayout(this);
 mLayout.setGravity(Gravity.CENTER);
 mTextView = new TextView(this);
 mTextView.setText(Saurav Mukherjee);
 mTextView.setGravity(Gravity.CENTER);
 mAnimation = new TranslateAnimation(100f, -100f, 0.0f, 0.0f);
 mAnimation.setDuration(2000);
 mTextView.setAnimation(mAnimation);
 mLayout.addView(mTextView);
 setContentView(mLayout);
 }

 }
