Making the usage of .9png images compulsory!

Probably there is a smart way of installing only the required drawables on a
particular hardware, so that at least the installed application isn't
bloated!

[android-developers] Re: Resource linking / imports

2010-06-23 Thread Mark Carter

In this particular case, I would just use drawable-nodpi (using naming
like icon1_72px.png, icon1_48px.png) and then handle it all manually.

 seems we would either need to copy the actual icons into multiple
 directories, or create a resource alias file for each icon, neither of
 which is ideal (think 30+ icons across the app which needed
 duplicating).

 What I'm wondering is if there is a need for a single file which
 contains all of the resources to use within another resource

 icons which have mdpi and hdpi variants;

 drawables/icon1.png
 drawables/icon2.png
 drawables/icon3.png
 drawables-hdpi/icon1.png
 drawables-hdpi/icon2.png
 drawables-hdpi/icon3.png

 As the Dell Streak is a WVGA device that identifies itself as a large-
 mdpi device we wanted to use the -hdpi icons for it, but this would
 result in three new files containing resource aliases;

 drawables-large-mdpi/icon1.xml
 drawables-large-mdpi/icon2.xml
 drawables-large-mdpi/icon3.xml

 What I'm wondering is should this be a single file which contains a

 drawables-large-mdpi/imports.xml

 which contains;

 imports
  import source=drawables-hdpiicon1.png/import
  import source=drawables-hdpiicon2.png/import
  import source=drawables-hdpiicon3.png/import
  /imports

 This does away with the file-per-resource requirements of the current
 configuration and it allows resources for multiple other directories
 to be included because the source could refer to any other resource
 directory.

 So, do people think this would be of use, or have I missed something
 which makes this whole idea obsolete?

[android-developers] Re: Resource linking / imports

2010-06-23 Thread Mark Carter

Second thoughts, a better workaround would probably be to just use
your highest resolution icons and put them in drawable. Scale them
(down) at runtime. If you have a load of users running normal-mdpi
screens, then you might want to put lower res icons in drawable-normal-
mdpi. For those users running small-hdpi, normal-ldpi etc, tough luck!

But anyway yes, in general, this import approach to indirection
would be useful...

  With the new security model of Android 2.2 writing to this kind of

  So here is my question:
  Is there still any way to temporary deactivate the lock pattern as

Re: [android-developers] Re: Avoiding GPL

2010-06-23 Thread Sean Hodges

You really need to consult a specialist on this subject, developers
(including me) have a tendency to give out I am not a lawyer type
advice, which is inherently unreliable.

In the strategy you describe, I believe putting A and B in the same
APK means you are distributing both components as a single piece of
software. A person cannot modify and distribute B without either
bundling closed-source A, or modifying the build process (which also
violates the GPL). You would be closer to a solution if you created 2
separate APK's, as long as A and B are completely independent of each
other.

The nature of the GPL is that the authors *do not want* their code
distributed in a closed-source solution, and this is exactly why it is
so difficult to find a legal way to do it. If you want to mix
licences; seek legal advice, and/or contact the authors about the
possibility of a dual-licence solution.

 Yeah David is right.If you link your application with open source libraries

 That's  why what I am trying to do is the code that uses open source I make

 Now since this service is running as a separate process so I am oblized to
 open only source code for this service...

 So the basic idea is
 A my app has some data and it needs to process this data... When it needs to
 process this data it runs a remote service B. This service process the data
 and returns back to A.

 B is the service that is using open source code and is running as a remote
 service. which is different process than app A.
 Source code for B  will be made open source.

 So as far as I know there should not be any legal issues and all can go as
 same .apk.

 this is wrong on many levels. As soon as you *distribute* the binaries

 This is true of GPLv2 or GPLv3.
 The LGPL is different, but conditions are very specific, and probably
 corresponds more to
 what you describe. However, this does not apply to the GPLv3.
 Please read the GPL Faq, it contains useful information.


 If you need to modify the source, then you need to be able to provide
 the modifications. If you need to integrate it with your app deeply so
 that you can't use the modified version without your app, then you
 need to open source the entire thing.

 IANAL but using a open source library in a closed source project
 without any modification should not provide any serious legal issues
 as long as everyone is properly credited and there is no stipulations
 in the license or on the creators website.

 I wouldn't recommend doing complex workarounds, because it just
 increases the amount of changes and dependencies between your app and
 the open source app, and shows that you were trying to circumvent
 things. Just do your best to not change it, and check the creators
 site to see if they sell alternate licenses that might server your
 needs better, if you do need to modify the source in certain ways.

[android-developers] Using SyncAdapter for syncing application data

Hi,

A little app design question: I was wondering if a custom sync adapter
would be appropriate when syncing normal application data that is

right choice for this use case or should I handle the sync in the app?

Re: [android-developers] Using SyncAdapter for syncing application data

Nice thought. But do you really think you need an adapter to answer this.
This is just a data sync functionality! If its tightly tied to UI
re-drawing/customization then you might go with writing SyncAdapter
otherwise you can, very well, stick with an interface!

[android-developers] Display a Dialog in non-Activity (simple Java) Class By passing Parameters

2010-06-23 Thread Nishant Kumar

Hi,
 I am trying to display a dialog box in a simple Java class that is
called from my main Activity but not successful.
Please help me to figure it out.

I am passing the required values as parametrs.


I have two class:

class MainActivity extends Activity  ::  Main *starting point *of
Application

class ShowMyDialog   ::  a simple java program In which I *generate an
URl* and *display a dialog with WebView*.
  I am passing the Acitivity from my
MainActivity to this class as a parameter in function.

But I am *unable to call* the onCreateDialog method that I have *defined in
the simple java class*.

However , If I define the *onCreateDialog method in MainActivity*, I am able
to display it* successfully.
*

*What Should I pass as Parameter to the non Activity class from MainActivity
class so that I am able to display the dialog as defined by showdialog
method in JAVA class ???*

My steps of source code is as follow:


class MainActivity extends Activity{

  onCreate{

Activity passingActivity =  this;//  THIS PASSING
PARAMETERS NEED TO BE CHANGED , getApplicationContext doesnot works for me
   ShowMyDialog showMyDialog = new ShowMyDialog(passingActivity);
   showMyDailog.displayMyDialog();

   }
}


class ShowMyDialog{

   public ShowMyDialog(Activity passingActivity){
this.passingActivity = passingActivity;
   }


public displayMyDialog (){
 int ID = 1;

passingActivity.showdialog(ID);
}

protected Dialog onCreateDialog(int position){

 Dialog dialog = new Dialog(callingActivity);
 dialog.setContentView(R.layout.dialogbrowser);
 WebView mWebView = (WebView) dialog.findViewById(R.id.webview);
 mWebView.loadUrl(http://www.google.com;);

 It is not safe to kick off anything that might take a while in a
 BroadcastReceiver, as it may cause your process to be terminated with
 the background equivalent of an application-not-responding error. At
 minimum, you need to move this to an IntentService and out of the
 BroadcastReceiver.

 It is also possible that speech synthesis can only be done by an
 Activity -- I have no idea if services can do it or not.

 Also, please bear in mind that the intent-filter you are presumably
 using for this application uses an action string that is not part of
 the Android SDK, and so your code may break in the future

- If a library implements a BroadcastReceiver should it be declared in

 My activity is working fine if I run it independently, but gives

 I am using sdk1.5 and I can't reduce my hierarchy.

 I am looking for alternative approach to tabhost.

Move all the logic that is common to the tab and the standalone
activity to a custom View class. Then use that View class as a tab in
the TabActivity and as the value for setContentView() in the
standalone activity.

No, there is no way to deactivate the lock pattern that I am aware of.

 No opinion?

My opinion is that deactivating the lock pattern via a regular setting
was a security hole. If the user wants a lock pattern, apps should not
change that. If the user does not want a lock pattern, the user is
perfectly capable of disabling it using the Settings application. The
exception would be if an enterprise would want to mandate the lock
screen be on and not disable-able, which runs counter to your apparent
goals.

My hope is that eventually stuff like this and custom lock screens
will become part of the new device admin APIs.

Re: [android-developers] layout problem when orientation changed

You need to reverse the order of the child elements of RelativeLayout.

In Android 1.6+, you can have a widget (e.g., your TextView) refer to
a widget (e.g.,  your FrameLayout) that appears later in the XML.
Android 1.5 does not support this. Hence, you need your FrameLayout to
appear first in your XML, then the TextView. You do not need to change
any of your attributes. Your layout should then work as expected.

Re: [android-developers] Resource linking / imports

Conceptually, the notion seems sound. However, I'm here to encourage
you to Just Do It.

On Wed, Jun 23, 2010 at 3:47 AM, Al Sutton a...@funkyandroid.com wrote:
 First off; I know the implementation of this should be discussed on
 the framework list, but I'm putting this idea out on here to see if
 there is a need for it.

This doesn't strictly need to be on the -framework list, since what
you want does not require any changes to the Android OS. You can
achieve your goals with zero modifications to anything in the AOSP.
Standardizing this would require changes to *tools*, and given a
working implementation, discussions on integrating the scheme into the
tools could probably just go straight to the -contrib list.

 imports
  import source=drawables-hdpiicon1.png/import
  import source=drawables-hdpiicon2.png/import
  import source=drawables-hdpiicon3.png/import
  /imports

Here's your AOSP-mod-free implementation:

Step #1: Modify the above XML format to be something that can live in
a resource directory but be ignored by the build tools. It might
qualify right now. It may require some tweaking. It is conceivable
that nothing will work, in which case toss it into an imports/
directory off the project root and add a target attribute to the root
element to indicate the resource directory you were originally
planning to have the file live in.

Step #2: Create the Android Image Importer (aii) tool. aii inject
finds the import file(s) and creates the alias XML files that you are
trying to avoid creating by hand. aii extract finds the import file(s)
and removes the alias XML files.

Step #3: Add aii inject to your toolchain as an early step in the
build, before the first aapt call.

Step #4: Add aii extract to your toolchain as a late step in the
build, probably at the end after the APK packaging/signing is complete

(for Ant, I'd do steps #3 and #4 by creating wrapper tasks around ant
debug and ant install and such that does the aii inject, chains to the
main task (e.g., debug), then does the aii extract)

(for Eclipse, you're on your own)

Net: you get your desired functionality without any changes to AOSP,
so you can see how well your plan works in practice.

Net++: you get a working implementation of the concept to use as a
basis for discussions with Xav and the tools team, because a real
implementation of the concept probably does pretty much the same
thing, just under the covers.

Writing the aii command should take somebody maybe an hour in Ruby, or
three months in Java. :-)

[android-developers] Google reader api

2010-06-23 Thread Martin Wallgren

I would like to sync some content in my application with google
reader. I know that there are apps on the market that access google
reader so I know that it can be done.

Are there any built in java apis in android to access google reader,
if not, what do you think is the best approach to implementing this.

I've googled a bit on this and I have some ideas on how to implement
this, but I don't want to reinvent the wheel if there already is a
working solution available.

Any thoughts on this subject?

[android-developers] Problem in GLSurfaceView??

2010-06-23 Thread Geefer

Hi,
I have recently seeen a few cases of the following error from one
particular device (Archos 5 running Android 1.6).The stack trace does
not cover any code in my app but appears to be a problem within the
Google code for the  GLSurfaceView that I am using.

Stacktrace:
java.lang.IllegalArgumentException
at com.google.android.gles_jni.EGLImpl.eglSwapBuffers(Native Method)
at android.opengl.GLSurfaceView$EglHelper.swap(GLSurfaceView.java:
901)
at android.opengl.GLSurfaceView
$GLThread.guardedRun(GLSurfaceView.java:1114)
at android.opengl.GLSurfaceView$GLThread.run(GLSurfaceView.java:968)

Is this something I am doing? I don't do anything special with the
GLSurfaceView so it should be responsible for setting up the OpenGL
surface correctly itself. The app works fine for several thousands of
users so I wonder why this error should pop up only on this device
type.

Any ideas how to debug?

Thanks

This particular functionality belongs in the system layer, not user-space apps.

Log an enhancement ticket on b.android.com, and consider writing a

make sure the mechanism is not exposed via the public API, so regular

  I provide a small tool called PatternControl via the market that give

  pattern for a definable amount of time. With other words: After
  entering the pattern, the pattern becomes deactivated for i.e. 5mins
  and re activates it self afterwards.

  Until now (Android  2.2) this was only possible by changing the
  settings directly, because there was no related API provided.
  (i.e.with something like
  setBoolean(Settings.System.LOCK_PATTERN_ENABLED, enabled))
  It is clear that this in not a good way, but from my knowledge there
  was no alternative.

  My hope was, that Froyo would introduce a new API to handle things
  like that legally.
  With the new security model of Android 2.2 writing to this kind of
  settings is now disallowed and the PolicyManager class seems just to
  offer password complexity options.

  So here is my question:
  Is there still any way to temporary deactivate the lock pattern as
  long as Android does not support such a delay functions natively?

  Thanks for you answer  Best regards

 AFAIK, the crash reports in the Dev Console are dependent on
 a) the users having the feature enabled on their phone and
 b) the user actually taking the time to report the issues

  However I would like to replace this with the Google version if possible.

 If you already have something in place, I would suggest you keep it, since,
 again, the Dev Console is dependent on users taking action.

  So it appears that there ust be something I need to do to 'enable' this
  feature.

 I don't think so. This feature was enabled on my phone for, AFAICT, all
 apps, many of which have not been updated in quite some time. This is a
 function of another, built in, auto-updating app on devices, it appears.

  I can't really imagine a mechanism that Google could have automagically
  enabled this without me recompiling with a later library

  How about pushing an auto-update to the app / process that already handled
 force-closes and ANRs?

[android-developers] Re: Service unable to call Java Class Methods

2010-06-23 Thread MobDev

First, you debug a Service the same way you debug anything else. You
set breakpoints in the appropriate lifecycle methods, or in routines
called from those methods.
Done that...

If I recall correctly, this works even if
the Service is running in a different process, but you might need to
enable debugging on the specific process via DDMS.
Tried that, when my app is started in the DDMS it will show my app
(myprojects.android.controlCenter) and, I guess, my service
(myprojects.android.controlCenter:remote)... When I try to debug that
it the DDMS will throw an error : No opened project found for
myprojects.android.controlCenter:remote. Debug session failed !

You don't quite say what makes you think your method isn't being
called. On the face of it, this would seem to mean simply that the
code that calls it doesn't run. But later you talk about It just
simply seems like the Service doesn't see the Logger class, but
with nothing to indicate what that means or why it seems that way. 
Well I have logging to the System.err.println within the Logger class
method which is being called, and it doesn't print to screen, so to me
it seems like that method is not being called or executed... That's
why I think the service doesn't see the Logger class : it cannot
call it's method otherwise I would see that in my console because of
the System.err.println() call within the called method...
I do know the Logger class works, it is being called by other
Activities and it prints happily everything it needs to print :D

After a lot of debugging I guess this is the answer who might help me
out :
Note that you refer to it as a singleton, but that's only meaningful
within a process. 
It seems the Service will make it's own Logger Singleton, which makes
creating an architecture with (for example) a static management layer
impossible... After all that static management class would be a
singleton as well, but having the service being in another Process it
will create it's own management class... So is there some way to
define the service to be created inside the same porcess ?

 First, you debug a Service the same way you debug anything else. You
 set breakpoints in the appropriate lifecycle methods, or in routines
 called from those methods. If I recall correctly, this works even if
 the Service is running in a different process, but you might need to
 enable debugging on the specific process via DDMS.

 You don't quite say what makes you think your method isn't being
 called. On the face of it, this would seem to mean simply that the
 code that calls it doesn't run. But later you talk about It just
 simply seems like the Service doesn't see the Logger class, but
 with nothing to indicate what that means or why it seems that way.

 There are four ways that this could happen. I doubt any of them
 actually apply to your situation, but it's worth listing:

 1) The class isn't found at compile time. The code won't compile, you
 won't actually be running the current code.

 2) The class isn't found at run time. Somehow it didn't get packaged
 up in the .apk. Since the classpath would be the same for both the
 Service and any Activities, you'd see the same ClassNotFound exception
 at runtime.

 3) The class is found, but gets an error while loading. This would
 give a ClassNotFoundError. The class will be successfully loaded once
 per process/.apk pair, so you'd normally get the problem for both, if
 in the same process, unless there's some initialization that happens
 between that allows it to load the second time. If in separate
 processes, if there's a dependency on things happening before the
 class loads, it might load in one process and not the other.

 Note that you refer to it as a singleton, but that's only meaningful
 within a process.

 4) The class is found, but loads, but the method itself is not found.
 This gets a MethodNotFoundException or other exception at runtime,
 depending on the exact behavior of the VM; I'm not sure it's fully
 specified. This situation only happens if code is successfully
 compiled against one version of the class, but finds a different
 version at runtime without the appropriate method. This would be
 similar to case #1 in origins. It is seldom found in practice, but
 usually doing a clean of the project and rebuilding will resolve it --
 often by turning into case #1.

 Anyway, your main solution is to actually debug the problem. Step
 through a call to your logger and see what happens and what doesn't
 happen.

 You should actually know if your Service is running in another process
 -- you'd have to set it up that way in the manifest. Just because
 you're using IPC doesn't mean it's in a separate process -- it just
 means you could set it up that way and the communication  would still
 work.

Re: [android-developers] Re: Using SyncAdapter for syncing application data

2010-06-23 Thread Connick

I've been using a sync adapter for application data and it worked out really
well. The downside is that there is no API to set the sync interval unless
you're targeting froyo. (at least to my knowledge) Kind of defeats the
purpose. I've had to roll with alarm manager for pre-froyo clients. My main
reason for going the sync adapter route was to play nice with the users
ability to manage background sync globally.

That means you have no service with an intent-filter containing an
action string that matches the value generated by
IScript.class.getName(). If you are taking that code from one of my
samples, the corresponding manifest from those samples is set up
properly:

http://github.com/commonsguy/cw-advandroid/tree/master/AdvServices/RemoteService/

 But, below way of binding works. i.e., Binding with the exported

 Intent i = new Intent();
 i.setClassName(com.mt.TestRemoteService,

This is extremely fragile. If the other application refactors its
code, your code will break.

 Why bind with Interface name is not working for me?
 ( Note: I have added an intent-filter on the service with a

Whatever you think you did, it is not working.

Rather than use my IScript.class.getName() trick, it is probably
simpler for you to just use the literal string. Copy whatever string
is in your action and paste it as a string literal in your Intent
constructor.

[android-developers] Re: Resource linking / imports

If the idea gets some support I might do what you've suggested. Thanks
for the idea.

 Conceptually, the notion seems sound. However, I'm here to encourage
 you to Just Do It.

 On Wed, Jun 23, 2010 at 3:47 AM, Al Sutton a...@funkyandroid.com wrote:
  First off; I know the implementation of this should be discussed on
  the framework list, but I'm putting this idea out on here to see if
  there is a need for it.

 This doesn't strictly need to be on the -framework list, since what
 you want does not require any changes to the Android OS. You can
 achieve your goals with zero modifications to anything in the AOSP.
 Standardizing this would require changes to *tools*, and given a
 working implementation, discussions on integrating the scheme into the
 tools could probably just go straight to the -contrib list.

  imports
   import source=drawables-hdpiicon1.png/import
   import source=drawables-hdpiicon2.png/import
   import source=drawables-hdpiicon3.png/import
   /imports

 Here's your AOSP-mod-free implementation:

 Step #1: Modify the above XML format to be something that can live in
 a resource directory but be ignored by the build tools. It might
 qualify right now. It may require some tweaking. It is conceivable
 that nothing will work, in which case toss it into an imports/
 directory off the project root and add a target attribute to the root
 element to indicate the resource directory you were originally
 planning to have the file live in.

 Step #2: Create the Android Image Importer (aii) tool. aii inject
 finds the import file(s) and creates the alias XML files that you are
 trying to avoid creating by hand. aii extract finds the import file(s)
 and removes the alias XML files.

 Step #3: Add aii inject to your toolchain as an early step in the
 build, before the first aapt call.

 Step #4: Add aii extract to your toolchain as a late step in the
 build, probably at the end after the APK packaging/signing is complete

 (for Ant, I'd do steps #3 and #4 by creating wrapper tasks around ant
 debug and ant install and such that does the aii inject, chains to the
 main task (e.g., debug), then does the aii extract)

 (for Eclipse, you're on your own)

 Net: you get your desired functionality without any changes to AOSP,
 so you can see how well your plan works in practice.

 Net++: you get a working implementation of the concept to use as a
 basis for discussions with Xav and the tools team, because a real
 implementation of the concept probably does pretty much the same
 thing, just under the covers.

 Writing the aii command should take somebody maybe an hour in Ruby, or
 three months in Java. :-)

 but my case is little different i guess,i just have the apk of the
 application i downloaded not the source code to make the changes
 accordingly.
 I am trying to run it on N1 which has 2.1 update1.
 so,how to use the above fix to solve this issue on my phone.

 pls help..

Ok, meanwhile a coworker of mine pointed out that this is a known issue with

 True, this is a Java question, not an Android question. SO it doesn't
 r-e-a-l-l-y belong here.

 I am glad we cleared that up.


 1) no, the NPE does not imply that isMarkAllReadPossibleCache is the
 null variable. Rather, it implies that in the course of trying to
 execute the get method of isMarkAllReadPossibleCache, the DVM
 encountered a null pointer.

 How so? Where do you see the get() method?


 2) the NPE occurred during the call to UpdateButtons(), which in turn
 took place during the call to the above get() method.

 I am really puzzled by that.
 You mean that looking at the stacktrace the NPE happens here:

 com.newsrob.activities.AbstractNewsRobListActivity.updateButtons(AbstractNewsRobListActivity.java:236)
 ?
 How do you come to this conclusion? In case of a non-wrapped exception
 isn't the top stack frame the place where the exception occurs? An exception
 blows up and the JVM provides the stacktrace up to this point. You think
 otherwise?

 3) to tell in any more detail where it came from, I would need the
 rest of your stack trace, which you chose not to show.

 The stack trace is complete.


 But now you
 have a better idea how to narrow this down by yourself, without
 exposing the code to us, I hope.

 I don't have a better idea and now you got me confused about how to read
 the stack trace.

 As this is kind of a last straw I would be delighted to learn something new
 about exceptions. Maybe that's the cue that's missing.

 and
  want to pick your brains.
 
  I recently got a couple of bug reports with a NPE that I don't
 understand
  and can't reproduce myself. Here is an abbreviated representation of the
  offending class. I tried to stay as close to the actual code as
 possible.
 
  public class EntryManager {
 
private static EntryManager instance;
private MapDBQuery, Boolean isMarkAllReadPossibleCache;
 
private EntryManager(Context ctx) {
  ..
  isMarkAllReadPossibleCache = new HashMapDBQuery, Boolean();
  ..
}
 
public static synchronized EntryManager getInstance(final Context
 context)
  {
 if (instance == null)
 instance = new EntryManager(context.getApplicationContext());
 return instance;
 }
 
 void fireModelUpdated(final String atomId) {
  ..
  isMarkAllReadPossibleCache.clear();
  ..
 }
 
public boolean isMarkAllReadPossible(final DBQuery dbq) {
  if (!isMarkAllReadPossibleCache.containsKey(dbq))
  isMarkAllReadPossibleCache.put(dbq,
  databaseHelper.isMarkAllReadPossible(dbq));
 
 return isMarkAllReadPossibleCache.get(dbq); !-- NPE is raised
 here
  }
 ..
 
  }
 
  In the last line from above a NPE is thrown. So the instance variable
  isMarkAllReadPossibleCache must be null, right? But I don't see where
 this
  could happen. It's initialized in the constructor and never set to null
  afterwards.
 
  For completeness here is a stack trace:

 Here's one website which offers a solution (and I've seen the same

 The solution is said to be to move the code:

 Well I've tried it, and it just causes me further bugs, and before I

 If anyone can shed any light on this, and offer the code which sorts

 ps. The bug is where you press the 'home' key during play, and then
 return to the game, because you can't call thread().start twice.

[android-developers] Google support number for Droid's sent to Developers from Google?

2010-06-23 Thread pcm2a

A few months ago Google sent top market developers a feww phone (Droid
or Nexus).  I was one of them and received a Droid.  I just now called
in to activate the Droid on my Verizon account and was told that it is
not activatable.  They said that the ESN number is tied to a business
account and currently active.  Verizon said the only thing I can do is
to contact Google, who sent me the phone, and work it out with them.

The paperwork with the phone came with no numbers or email addresses.

I have tried calling the Nexus support line, they could not direct me
anywhere.

I have tried emailing the automated robots that sent me emails about
the phone.

Is there anyone at Google that I can contact that would be able to
help with this?

There is a thread that details what you have to do to get your phone
activated, essentially it entails moving beyond the dumb bunnies who
answer the phone at Verizon and getting to one who can actually think,
a tough thing to do. Be persistent, ask for a supervisor and don't
take no for an answer. Once you get a thinking person on the phone, it
only takes a few seconds to get past this problem.

[android-developers] Background apps (Instant Messaging) being killed without user notification

Hello everyone!

I'm having another problem with my milestone that I'd like to share
with developers and Android coders: Whenever I run memory-intensive
applications while I have an IM app running in the background, the IM
app is often killed without any user notification whatsoever.

Take this scenario for instance (works every time on my Milestone):

1. A few background apps are already running: Sipdroid, Locale,
Titanium Backup's service...
2. Launch Nimbuzz (or Fring, eBuddy or Meebo - it's reproducible on
all of them)
3. Use lots of memory - for instance with a browser (open lots of
windows will full desktop sites), or by launching multiple memory-
intensive applications at once (Maps Navigation or other navigation
apps work well)

Sure enough, the logs show the following:

Re: [android-developers] Background apps (Instant Messaging) being killed without user notification

2010-06-23 Thread Kostya Vasilyev


Simon,

I think this should be taken up with developers of these apps.

In particular, my recommendations to them would be:

- Use a startForeground / setForeground call to mark the service as 
being important to the user, do it only while the user is logged in.


- Display a notification the phone's status bar, so the user knows if 
the service is still kicked out of memory.


- Consider using AlarmManager to restart the service and re-login if 
there is an active logged in session.

Re: [android-developers] Background apps (Instant Messaging) being killed without user notification

Hello Kostya,

Do you think that they really all just made a mistake with their
programming? I thought that since it happens with all four apps, it
must be a general Android problem...

I'll post on their forums though.

Thanks for your advice so far. :)

Kind regards,

Re: [android-developers] Background apps (Instant Messaging) being killed without user notification

2010-06-23 Thread Sean Hodges

What Kostya said.

When memory is critically low on the device, apps are killed outright
to regain user control. Android was originally designed for mobile
phones, and nobody wants to miss an incoming call because they have
run out of memory. No notification is passed to the user, because well
written apps should handle this themselves. Some will want to alert
the user, others will want to carry on where they left off without
bothering the user about the event.

As a user, you can do the following:

A) Contact the developers of Nimbuzz and explain the problem you are
having. They have probably not benchmarked against such high load, and
as a long-running service the app should really have a recovery
process for when it is killed. An alarm manager could periodically
check an is logged in flag, and automatically log the user back in
if the background service was killed.

B) Don't try to run so many tasks at once, or purchase a phone with
more available memory (depending on your individual requirements).

Re: [android-developers] Background apps (Instant Messaging) being killed without user notification

By the way: All the apps have already implemented the notifcation icon
in the status bar. The problem is, it doesn't change when the app is
killed in the background, so the user doesn't know that it's been
killed.

:(

 Simon,

 I think this should be taken up with developers of these apps.

 In particular, my recommendations to them would be:

 - Use a startForeground / setForeground call to mark the service as
 being important to the user, do it only while the user is logged in.

 - Display a notification the phone's status bar, so the user knows if
 the service is still kicked out of memory.

 - Consider using AlarmManager to restart the service and re-login if
 there is an active logged in session.

Ah OK,
learned something new... Thanks Mark.
Where do I get the source code you mentioned?
I guess they are not included in the SDK because I wasn't able to find
them there.
Sorry for all this newbie questions, but I'm still working on getting
into the platform (I'm coming from Windows Mobile)...

 That's for ListView. ListView is not AlertDialog.

 AlertDialog uses android.R.layout.select_dialog_multichoice for its
 rows (after spending a few minutes hunting through the source code for

I used Google Code Search:

Include the package:android clause in there, and it will restrict your
search to Android-related code. Otherwise, it's pretty much the
standard Google search syntax, from what I can tell.

You can download all the source here:

http://source.android.com

But it's rather big.

As far as I know, unless you deliberately create a SQLite database on 
the SD card, the databases are created in a protected area of the 
phone/device's storage. Other applications don't have access to them at 
all unless your app has a shared key if I remember correctly, and I 
think they (the attacking apps) have to be signed with the same key 
that your app is as well.

Re: [android-developers] Re: Android libraries

2010-06-23 Thread Xavier Ducrohet

That's correct.

At the moment the manifest of the library is only used to compile the
resource of the library and figure out its package name, so it doesn't
need to contain permissions, activities, services, etc... used by the
library.

However, all projects using the library must include those in their
own manifest.

In the future (hopefully not too distant) we'll be able to merge the
content of the library manifest so that you don't have to do it
manually for all projects using the library.

Re: [android-developers] Background apps (Instant Messaging) being killed without user notification

2010-06-23 Thread Kostya Vasilyev


Simon,

Android 2.x framework has an important change in this area, trying to 
nudge developers towards better behaving services.


Since 2.x, marking a service as foreground requires a status bar 
notification, so the user knows that a service is running.


Regarding lingering status bar notifications - I just verified that if a 
notification is displayed using the new 2.x API, it disappears when the 
service is killed.

[android-developers] ListView Groups? Please

2010-06-23 Thread Tommy

Hey everyone,

Is there a way to do groups in a listview? Like I have a list of
certain states, each state has its own sublist. I'd sort of like to
replicate the HTML optgroup/option setup where you have a parent group
then child groups. Is there a way to do this built in or would I have
to do something tricky with a custom view for Parent elements then
switch the view back to the child element style?

Thanks for the help and input and your time,

Tommy

You have different rows return different View types, one for headings
and one for the main rows. To do this, in addition to having the
appropriate smarts in getView() or newView()/bindView() in your custom
Adapter, you need to make sure you properly override getItemViewType()
and getViewTypeCount(). You may also wish to deal with isItemEnabled()
so people do not click on your headings if those are not meant to be
clickable.

Here is a reusable component that can wrap a lot of this up for some
sorts of lists:

[android-developers] Re: notifyDataSetChanged() not updating listview after orientation change

2010-06-23 Thread Streets Of Boston

thisListView.setAdapter(r_adapter);
r_adapter.notifyDataSetChanged();

If you do 'setAdapter', calling notifyDataSetChanged() is not
necessary, if i'm not mistaken. But calling an extra
notifyDataSetChanged() should hurt.

Override the adapter's getItem and getCount methods and put a break-
point in these methods. See if these get hit and, if they do, see what
values they return.

         private ListView listView;

         public ReminderAdapater(Activity activity, ArrayListClass_Reminder

You cannot specify arbitrary frequencies, but perhaps the tones you
