[android-developers] Re: Unit Testing - Activity shutdown
Got this all working and reliably. I still use a state variable to tell me where I am in the state machine - not ideal. My reliability problems seem to have been down to using SharedPreferences to hold state between tests. Thanks for the responses.

Elk lancaster.dambust...@gmail.com wrote: Can I get clarification here? Does your application call finish() at some point? If so, at what point? The Android design guidelines strongly discourage the use of an exit button. You should see that most apps don't have one. The way to exit an application is to switch to another one (including a phone call) or go to the Launcher/Home. Whenever you switch, the onPause() method for the foreground Activity of your app should be called. Whenever you switch back, the onResume() method should be called. Can you please point me at the guidelines you are referring to? I have seen many references to the finish() method, but nothing discouraging its use. In the API it states... void finish() - Call this when your activity is done and should be closed. In my scenario, the user rejects the Terms Conditions in a dialog - and this seems the ideal thing to do, No? I acknowledge that sometimes you may want to start a child *Activity* and then kill it when you're done with it. To do this, use finishActivity() with a result code. You may also want to start a service when your app starts, but give the user the option to stop the service if it's not being used. That's OK too, but you shouldn't shut down the app itself. In short, the Android model is that you leave the application paused, and let Android destroy it to free up resources. If Android does this, it should always call the onPause() method of any Activities that are still running. Can you describe your test harness in more detail? To unit test an Activity, you shouldn't need anything more than InstrumentationTestRunner and ActivityInstrumentationTestCase2. This is documented under Testing and Instrumentation in the Android 2.2 Developer's Guide. I am using the ActivityInstrumentationTestCase2 as you suggest and calling getActivity() to start the Activity. I then do button.performClick() which causes 'finish()'. I am hoping to reliably test that the Activity has paused, stopped or whatever happens. I have refactored and now have a unit test which (via a state variable) does work, but not reliably - this may be another story :-) Thanks Ian Hunter -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Market expanding to technically non-compliant devices?
Yes, things are getting confusing if not messy. The Logitech TV Cam accessory for the Logitech Revue Google TV adds a camera to Google TV http://www.logitech.com/en-us/smartTV/accessories/devices/tv-cam but it can reportedly not be used by Android apps: The TV Cam cannot be accessed from other applications at this time http://forums.adobe.com/message/3256491#3256491 Great, so there *is* a camera for this Android device (Google TV) but it cannot be used by regular Android apps. Now this probably means that Android camera apps will simply remain invisible on the Android Market for this Google TV, but for developers it is just as important to know if a device is compatible with their app or not - to be able to tell their customers. One should not have to scour web forums in the hope of getting an indication of that. In other words, should it not be *required* that Logitech clearly indicates on their website that Logitech TV Cam does not work with third-party (and Google's!) Android camera apps, and *only* works with their own proprietary video call app? I currently cannot find this on the Logitech TV Cam product page http://www.logitech.com/en-us/smartTV/accessories/devices/tv-cam and even if it is hidden somewhere in the small print that is hardly practical for developers who need to be able to quickly tell compatibility for a range of new devices to answer customer inquiries. Looks like there should be some additional requirements for manufacturers here in order to be allowed to use the Google TV brand, because everybody already knows that Google TV runs Android http://www.google.com/tv/developers.html and if there is a camera accessory everybody would assume that Android camera apps would run fine and not be in for an unpleasant surprise or a heap of uncertainty. Thanks! On Nov 30, 8:20 am, Spiral123 cumis...@gmail.com wrote: GoogleTV.

2 Hall1 1
Third record must be
3 Hall2 2
If user enter other roomname thenit must be
4 Kitchen 0
again insert suppose Hall then
5 Hall 3 (Because last Hall suffix is 2)
Means I want different suffix for different RoomName. But using above
code I get output as
1 Hall 0
2 Hall 1 1
3 Hall1 1
4 Hall1 1
Each time I get Suffix as 1.
What is wrong in this code? And if I remove where clause and write it
as
if (roomExist)
{

Then here it is not maintaining different suffix for different

the oncreate() functions is called in this way:

findViewById(R.id.card_images_layout);
for (int i = 0; i this.card.images.size(); i++) {
b = (ImageButton) findViewById(R.id.card_image);
b.setImageBitmap((this.card.images.get(i).getImage_data()));
contanier.addView(b);
}
But I take this error

parent. You must call removeView() on the child's parent first
Is my solution which is incorrect or I make wrong something?

Hi,
You are adding the same ImageButton again and again.
You are getting reference of some existing button:
b = (ImageButton) findViewById(R.id.card_image);
and adding that button to the view again and again! So, you are
getting the runtime error.
Hint: You need to create NEW ImageButtons if you want multiple image
buttons.
b = new ImageButton();

[android-developers] Re: Back key behaviour between Activity Groups.
Yes, I have done that.
The problem is that I will have to add manually add this PlayBack
custom layout to each of the view.
Now more over, even if I do that, For each new instantiation of view,
I have to do bunch of instiations. Like connecting to background
service. Which is costly.
So I was wondering, If I could have to inflate it only once.

Mahesh,
Why dont you make a different class, say PlayBackView, extending
LinearLayout and place the layout of the common component Playback
bar in a different layout xml, say playback.xml.
Now inflate the playback.xml in the PlayBackView.
Now you can add this your custom view in any of the layout xml (home,
A, B, C)
as:
?xml version=1.0 encoding=utf-8?
FrameLayout xmlns:android=http://schemas.android.com/apk/res/
android
android:orientation=vertical android:layout_width=fill_parent
android:layout_height=fill_parent
com.packagename.PlayBackView
android:id=@+id/playbackview
android:layout_width=match_parent
android:layout_height=wrap_contentt /
ImageView --- etc etc/
/FrameLayout
In the PlayBackView class, you can define the onClick handlers or any
other event handler as you want.
Hope this will help you.

Since, A has the playback bar, now I when I start B from A, I call
setContentView from A to show B.
The problem is, once I call setContentView to show B, and then if the
user presses back key in B, then it goes to home screen, instead of
coming to A.
I have seen some snippets on web, which maintain the view stack and
when user presses the back key they pop up the previous view.
I couldnt implement that.
Questions :
1) Is there any better way to having a activity like Playback bar/
Status bars across all the views/activities ?
2) If the above way is the only way to do it,then how can I handle the
back key?
With Regards
MS.

[android-developers] Re: App freezes when the power key is pressed
After I insert the USB cable, there is three options “1. Connect your phone. 2. Install PC Companion. 3. Charge phone.” No matter which option I have selected, the app will just freeze without any message. When I press the power key to go to power save mode and then press it again to resume the application, the app will just freeze without any message. I test by doing lots of screen orientation changes, like you recommended.But I can not replicate the freezing problem on my Samsung galaxy. I don't have the SonyEricsson X10 and X8 devices to test on. I try to simulate a power key press on the emulator, by pressing the power button. I debug and onKeyDown is called, but onpause() and onResume() is not called. Doesn't onpause() and onResume() get called when the power key is pressed? I can not simulate insertion of a USB cable on the emulator. My onStart method only call the superclass, so I don't see how an exception could be raised here. My onResume method also sets the graphics thread to setRunning(false), which means that the thread will continue, but it will not execute the drawing loop.

Re: [android-developers] Start default email client
You can't. You can start *an* email client. Which one depends on what the user has installed, and which application he chooses. The code I use is: Intent view = new Intent(Intent.ACTION_VIEW); StringBuilder uri = new StringBuilder(mailto:;); uri.append(email address here); uri.append(?subject=).append(Uri.encode(subject here)); uri.append(body=).append(Uri.encode(message body here)); view.setData(Uri.parse(uri.toString())); startActivity(view); There are other ways to specify subject and body, but this one works with certain buggy email clients (H*C Se*se). -- Kostya 30.11.2010 13:30, pedr0 пишет: Hi at all, How can I make a intent to start the default email client?

So the thing now is that test is true in the update-Runnable, but it
is still false when I call it in onDrawFrame.
Why is that the case, I am getting really desperate, can anybody help
please!?!?
Thanks a lot

[android-developers] Re: Back key behaviour between Activity Groups.
ok If this is the case then you can implement the Back key in your
code as:
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
// your implementation
return true;
} else {
return super.onKeyDown(keyCode, event);
}
}
or if you are using API 8
@Override
public void onBackPressed() {
// TODO Auto-generated method stub
super.onBackPressed();
}

Yes, I have done that.
The problem is that I will have to add manually add this PlayBack
custom layout to each of the view.
Now more over, even if I do that, For each new instantiation of view,
I have to do bunch of instiations. Like connecting to background
service. Which is costly.
So I was wondering, If I could have to inflate it only once.

Mahesh,
Why dont you make a different class, say PlayBackView, extending
LinearLayout and place the layout of the common component Playback
bar in a different layout xml, say playback.xml.
Now inflate the playback.xml in the PlayBackView.
Now you can add this your custom view in any of the layout xml (home,
A, B, C)
as:
?xml version=1.0 encoding=utf-8?
FrameLayout xmlns:android=http://schemas.android.com/apk/res/
android
android:orientation=vertical android:layout_width=fill_parent
android:layout_height=fill_parent
com.packagename.PlayBackView
android:id=@+id/playbackview
android:layout_width=match_parent
android:layout_height=wrap_contentt /
ImageView --- etc etc/
/FrameLayout
In the PlayBackView class, you can define the onClick handlers or any
other event handler as you want.
Hope this will help you.

Hello All,
My app is kind of a music app and I have a playback bar that I need to
be visible across all the views.
I had three activities, A/B/C. Instead of adding the playback bar
explicitly to all A,B,C. I added the Playback Bar to A and made A,B,C
as ActivityGroups.
Since, A has the playback bar, now I when I start B from A, I call
setContentView from A to show B.
The problem is, once I call setContentView to show B, and then if the
user presses back key in B, then it goes to home screen, instead of
coming to A.
I have seen some snippets on web, which maintain the view stack and
when user presses the back key they pop up the previous view.
I couldnt implement that.
Questions :
1) Is there any better way to having a activity like Playback bar/
Status bars across all the views/activities ?
2) If the above way is the only way to do it,then how can I handle the
back key?
With Regards
MS.

[android-developers] Re: LocationListener sometimes not receiving updates from network provider
Hi Igor,
Thanks for your reply, it is much appreciated. Thanks also for
pointing out the issues with the code I provided. However, this was
merely a stripped-down outline of what I am doing. The use of
mCoarseLocationListener is a type from the strip-down process, and I
agree that the LocationProvider variable is not necessary.
However, the problem remains that while the code works fine in 95% of
cases, there are still 5% of cases where I never get a call to
onLocationChanged. Any suggestions as to why this is the case would
still be much appreciated.
Best,
Michael.

Michael,
According to Android documentation the following call
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,
0, 0, this);
requests updates from WiFi or cellular network which means you should
get some update (from cell tower) even if WiFi location is not
available. However, I've seen cases when Google map application failed
to set map to MyLocation for several minutes while driving on a
freeway.
Back to your code. I think you need to replace
getLastKnownLocation(mCoarseLocationProvider) with
getLastKnownLocation(LocationManager.NETWORK_PROVIDER) - it is not
clear where do you get mCoarseLocationProvider.
Also you don't need to use LocationProvider variable in your code
fragment:
public MyLocationListener() {
mLocMan =
(LocationManager)getSystemService(Context.LOCATION_SERVICE);
if
(mLocMan.getLastKnownLocation(LocationManager.NETWORK_PROVIDER) !=
null) {
mCurrentLocation =
mLocMan.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
}
mLocMan.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0,
this);
}
Check the following link which has a lot of useful
suggestions:http://developer.android.com/guide/topics/location/obtaining-user-loc...
Bets regards

Hi folks,
I have a location listener running in a foreground service. The
listener registers for wireless network updates in its constructor. In
the majority of cases, location updates are received as expected.
However, log entries from the live app show that for about 5% of my
users, location updates are never received even though wireless
network location is enabled on the phone (I check this through the
LocationManager.isProviderEnabled method). That is, onLocationChanged
is never called, at least not within say 20 minutes of registering the
listener.
Does anybody have any idea why this might be? Are there cases, or
certain geographic areas, where you would not expect wireless
locations to be available?
A stripped-down outline of the location listener code is shown below:
class MyLocationListener extends LocationListener {
private Location mLocation = null;
public MyLocationListener() {
mLocMan = (LocationManager)
getSystemService(Context.LOCATION_SERVICE);
if (mLocMan.getLastKnownLocation(mCoarseLocationProvider) !=
null) {
mCurrentLocation =
mLocMan.getLastKnownLocation(mCoarseLocationProvider);
}
LocationProvider lp =
mLocMan.getProvider(LocationManager.NETWORK_PROVIDER);
mLocMan.requestLocationUpdates(lp.getName(), 0, 0, this);
}
public void onLocationChanged(Location loc) {
mLocation = loc;
}
}
I verify through flurry logs that the network location provider is
indeed obtained and enabled, and that mLocation == null after about 20
minutes.
Any suggestions would be enormously appreciated. I am running out of
ideas for how to fix this, and I cannot replicate the issue on my own
test devices.
Cheers,
Michael.- Hide quoted text -

Yes, they will be scaled, provided you design your app to do so. Say, for example, if you have an ImageView/ImageButton, there is a property scaleType. If you don't change it, the images will be scaled. But if you are using that, then, depending on the type, it might or might not scale. But, I am still not clear about your confusion.

One should not have to scour web forums in the hope of getting an indication of that. In other words, should it not be *required* that Logitech clearly indicates on their website that Logitech TV Cam does not work with third-party (and Google's!) Android camera apps, and *only* works with their own proprietary video call app? I currently cannot find this on the Logitech TV Cam product pagehttp://www.logitech.com/en-us/smartTV/accessories/devices/tv-camand even if it is hidden somewhere in the small print that is hardly practical for developers who need to be able to quickly tell compatibility for a range of new devices to answer customer inquiries. Looks like there should be some additional requirements for manufacturers here in order to be allowed to use the Google TV brand, because everybody already knows that Google TV runs Androidhttp://www.google.com/tv/developers.htmland if there is a camera accessory everybody would assume that Android camera apps would run fine and not be in for an unpleasant surprise or a heap of uncertainty.

[android-developers] Re: lock sqlite file
I'm not sure you can lock the file (at least without having root permissions). I am not that familiar with that in java, but I would look for a read write lock of some kind, using the write lock only when you need to transfer the file, and the read lock when you are writing into the db in any of your methods. In this way all the writes won't lock, unless you are transferring the file, and the transfer process will wait for the end of any current write.

[android-developers] Re: Do Androids dream of rule engines?
Hi Bob. Thank you for your feedback! The reason why I didn't put why rule engines are needed on Android in the post and on the site (except a little bit on the history page) is because I'm primarily Java SE/J2EE guy and no expert in Android. This is why the post is a question. It is for Android experts to decide whether it is needed and how it can be used. If the community shares these thought with me, I'll gladly publish them in the Event Bus online documentation, given posters permission. My reasons to believe that there is a need are listed below: - About two years ago Sun Java ME guys from JCP approached me and said that Hammurapi Rules (the predecessor of Event Bus) is the only rules engine which runs on Java ME and that there is a great need in rule engines on mobile devices. They wanted to come up with Java spec for rule engines on mobile devices. (Then Oracle acquired Sun and it didn't go anywhere.) This was the primary factor to build Event Bus in a way that it runs on both Java SE and Android. - I think that there are a lot of events flying around in a mobile device. A mobile device communicates with the external worlds and these communications aren't fast. This is why parallel predicate evaluation and parallel handler execution was introduced. - I also thought about leveraging it in UI as you described, but again - I do not possess the expert power in this area - I know how to build UI's, but I don't do it on a daily basis. So I decided that it's better not to say something than to say something wrong. Event Bus supports retractions - you can remove event from the bus and all conclusions based on this event will be invalidated. However, in the current release retraction does not activate any handlers, as it used to be in Hammurapi Rules. Thank you for pointing it out - I'll add the concept of retraction-activated handlers to the bus. Do you mind if I incorporate your feedback into the Why section on the Android page? --- Best regards, Pavel. On Nov 29, 10:07 pm, Bob Kerns r...@acm.org wrote: Hi, Pavel. I would like to see the Code of Hammurapi ... I hope it's not written in cuneiform! :=) Great name! I think it would be helpful if you were to be a bit more explicit about what makes you believe there is a need for aruleengineon Android. I've written moreruleengines than I can recall offhand, and a big fan ofruleengines in general, but I'd find it hard to characterize just why and when you need one on Android. I imagine people less familiar withruleengines would find it even more difficult, even when they're facing a problem well-solved with it. So I'd encourage you to write a bit more about why and how you see it being useful on Android. Looking over your site, it looks like you are using something similar to a Rete network for your matching. And that you've extended this with asynchronous execution of predicates and handlers? Perhaps one scenario is when you have slow interactions (e.g. network interactions) which have to asynchronously interact with the UI, and not block the event thread? Expressing this as Hammurapi rules might be a good way to to integrate such background interactions and the UI? This would avoid a lot of threading pitfalls and UI coordination headaches. I have found thatruleengines are a very nice way to manage complex UI concerns, such as when buttons should be activated, what values should populate drop-down lists, etc. Especially when theruleengine supports retraction -- so that if one of the conditions that led to a button being activated is no longer true, the button is then deactivated automatically. Do you support any form of retraction -- reversing an action (un-asserting a fact) when the condition that led to it is no longer true? Given how simple individual Android screens are, and how they are spread across multiple activities, I'm not sure whether this makes android need rules less -- or more! Perhaps more, as the logic around maintaining the various bits of state across activities should perhaps be best managed in a way decoupled from individual screens.

[android-developers] Detect OSK shown / hidden events
Hi all! We're trying to trigger an animation whenever the on screen keyboard is shown or closed. There doesn't seem to be any options to register listeners directly to that event either in the EditText or in the window / app in general. Only solution I managed to find was an older post here where solution was to listen to size changed events. From this thread: http://groups.google.com/group/android-developers/browse_thread/thread/9d1681a01f05e782 Unfortunately, that solution doesn't work in landscape mode. For some reason the onSizeChanged doesn't get called in landscape mode. As the previous thread is already very old I was hoping that maybe in 2.0 or later versions there would be an API for that. What is the best way to get notifications when the OSK is opened / closed? Thanks! Juhani -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Market expanding to technically non-compliant devices?
What do you mean what? Your phone touchscreen app will work fine with your touchscreen phone. with luck your app should then be able to find your GoogleTV device and get it to do stuff. How you talk to it and what stuff you can get it to do we will find out when we finally get to see the SDK. As blindfold says earlier in the thread, although it appears that manufacturers can turn off hardware availability (e.g. TV Cam) that is going to be frustrating to developers and end users alike. Another example that will potentially irritate me is that the Logitech device has hardware IR and RF remote sensors built in but is currently hardwired to only accept specific Logitech Harmony RF remotes. I expect the SDK will include functionality to deal with remotes - but I hope the agreement between Logitech and Google requires Logitech to enable all the capabililites of the device.

I currently cannot find this on the Logitech TV Cam product pagehttp://www.logitech.com/en-us/smartTV/accessories/devices/tv-camand even if it is hidden somewhere in the small print that is hardly practical for developers who need to be able to quickly tell compatibility for a range of new devices to answer customer inquiries.

Re: [android-developers] getLookupUri(contactId, lookupKey) clarification
This was a bug in 2.1. Lookup key was based on the contact name for unsynced contacts, which created the problem you are describing. As of 2.2 we use raw contact ids instead. In both cases we use stable server-side ids for synced contacts. On Nov 29, 2010 11:01 PM, LSDsl gls...@gmail.com wrote: Hi. Misunderstand with this (getLookupUri(contactId, lookupKey)). I store id and lookup in my application. After resave contact (change name for example) lookup also changes (but ID not change) I cannot select contact from DB using getLookupUri(contactId, lookupKey). Why? In docs When both IDs are present in the URI, the system will try to use the long ID first. That is a very quick query. If the contact is not found, or if the one that is found has the wrong lookup key, the content provider will parse the lookup key and track down the constituent raw contacts.. So long ID is correct in my situation. So can somebody clarify this situation and say how what information I must store to 100% select contact in future? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: What's the best way to have your app 'sleep' for N milliseconds?
The Thread.sleep(1000) is probably not the best idea on Android
because responsiveness is an issue if you care about user ratings ;-).
With Thread.sleep() the app just sit's there and waits and won't
respond to user input.
I would recommend using something like:
private static final int WAKE_UP_DELAY = 5000;
private static final int WAKE_UP_CALL = 0;
private Handler handler;
private Runnable wakeUpCall = new Runnable() {
@Override
public void run() {
handler.sendEmptyMessage(WAKE_UP_CALL);
}
};
handler = new Handler(new Handler.Callback() {
@Override
public boolean handleMessage(Message msg) {
if (msg.what==WAKE_UP_CALL) {
// change message, your code goes here...
// let's start the timer again
handler.postDelayed(wakeUpCall, WAKE_UP_DELAY);
return true;
}
return false;
}
}
);
handler.postDelayed(wakeUpCall, WAKE_UP_DELAY);
// do something...
The // do something part is the important difference to the
Thread.sleep(). With the latter the app sleeps while with the my
version the app can do whatever the app is supposed to do.
And after a certain time (5 seconds in my example) you can change the
message or whatever else there is to do.

You can't attach arrays of Bundles to intents without your own mechanisms. Sure you can. Bundle extends parcelable, so you can attach an array of parcelables that are Bundles.

[android-developers] Multiple clickable elements within a listview row? Good or bad idea?
Hi, I've got a pretty standard list control, it's got about 4 lines of text. Some of the text in each row might start a new activity when clicked, like: Row 1 John Doe [clickable, starts activity] 1234 Main Street [clickable, starts activity] Last Read: The Great Gatsby [clickable, starts activity] I haven't tried making multiple focusable items within a listview row for about a year now, but I think it caused issues when using the scroll wheel on the device of some sort. Is this a good pattern to use, or is there some other mechanism we can go with? Alternates are displaying a dialog when a row is clicked with buttons for each clickable element, a long-click to activate an options dialog, etc. I see that the twitter app has the multiple clickable elements per row pattern implemented, so maybe it's ok to go with?

Ok that's weird. If you have nothing in your onStart and your onResume sets the loop as running for your drawing loop, then that is where you should have a look. My guess would be that the restarting of your looping via setRunning doesn't do what you think and that it is just not restarting at all so that you don't have any drawing going on. Or maybe you are creating objects in your onCreate method that get destroyed when your apps looses focus and that are never recreated again because onCreate is only called the very first time you launch your activity.

[android-developers] Re: Do Androids dream of rule engines?
Hi, I think Androids should dream of rule engines ! I am working on global event distribution and event processing at the network's edge (e.g. a mobile phone) and I recently ported several existing middlewares to Android. One of these is Esper, a complex event processing runtime. I do not know that much about rule engines, but a colleague of mine recently evaluated the suitability of complex event processing engines and rule engines for protocol verifications. Therefore, I assume there are scenarios in which both approaches are reasonably suited. In my case, I use a complex event processing engine to deal with the multitude of events coming from an Android device's physical (gps, acceleration, etc.) as well as virtual sensors (application specific sensors). The same could be achieved with rule engines as well. This is my reason 1 why Androids should dream of rule engines. Reason 2 is based on my efforts for porting Jadex Active Components to Android. Using Jadex one may modularize applications into self- contained agents, processes, etc. A very nice paradigm. Until now, I only managed to port the so called Jadex MicroAgents as well as BPMN-based Agents, but Jadex also supports the development of intelligent BDI Agents (BDI = Belief, Desire, Intention), which are able to reason about the world and what they should do therein. Such a reasoning process is in most agent systems based on a rule engine (in case of Jadex it is Jadex Rules), which sorts out what plan an agent should follow to reach its goals. Unfortunately, this has not been ported yet. Therefore, no BDI agents on Android, which is really a pitty, as agent-oriented software engineering offers a multitude of nice concepts for building distributed applications ... and mobile devices are right on the way to play an active role in distributed systems. To cut a long story short: it's time that more heavy-weight components (like rule engines) are finally supported by mobile platforms, because this allows developers to benefit from established desktop concepts even in the mobile world. Cheers, Dirk ps: sorry for being verbose On 30 Nov., 15:40, Pavel Vlasov pvlasov...@gmail.com wrote: Hi Bob. Thank you for your feedback! The reason why I didn't put why rule engines are needed on Android in the post and on the site (except a little bit on the history page) is because I'm primarily Java SE/J2EE guy and no expert in Android. This is why the post is a question. It is for Android experts to decide whether it is needed and how it can be used. If the community shares these thought with me, I'll gladly publish them in the Event Bus online documentation, given posters permission. My reasons to believe that there is a need are listed below: - About two years ago Sun Java ME guys from JCP approached me and said that Hammurapi Rules (the predecessor of Event Bus) is the only rules engine which runs on Java ME and that there is a great need in rule engines on mobile devices. They wanted to come up with Java spec for rule engines on mobile devices. (Then Oracle acquired Sun and it didn't go anywhere.) This was the primary factor to build Event Bus in a way that it runs on both Java SE and Android. - I think that there are a lot of events flying around in a mobile device. A mobile device communicates with the external worlds and these communications aren't fast. This is why parallel predicate evaluation and parallel handler execution was introduced. - I also thought about leveraging it in UI as you described, but again - I do not possess the expert power in this area - I know how to build UI's, but I don't do it on a daily basis. So I decided that it's better not to say something than to say something wrong. Event Bus supports retractions - you can remove event from the bus and all conclusions based on this event will be invalidated. However, in the current release retraction does not activate any handlers, as it used to be in Hammurapi Rules. Thank you for pointing it out - I'll add the concept of retraction-activated handlers to the bus. Do you mind if I incorporate your feedback into the Why section on the Android page? --- Best regards, Pavel. On Nov 29, 10:07 pm, Bob Kerns r...@acm.org wrote: Hi, Pavel.

I think it would be helpful if you were to be a bit more explicit about what makes you believe there is a need for aruleengineon Android. I've written moreruleengines than I can recall offhand, and a big fan ofruleengines in general, but I'd find it hard to characterize just why and when you need one on Android. I imagine people less familiar withruleengines would find it even more difficult, even when they're facing a problem well-solved with it. So I'd encourage you to write a bit more about why and how you see it being useful on Android. Looking over your site, it looks like you are

[android-developers] Change Relative layout background dynamically Issues
Hi everyone. I have a relative layout that I want to change the background according to a set of features. For some reason when I try to change the background image I get a null pointer exception. Currently in the onStart method I call a function the handles valedating then determins what background image should show. The code for the image change I have is below: RelativeLayout background = (RelativeLayout)findViewById(R.id.currentWeatherBackground); background.setBackgroundResource(R.drawable.blue_background); blue_background is in my resource folder and I can use it just fine if I type it into the XML.

Re: [android-developers] Android: BackupManagerService

[android-developers] Question about services
I've been reading Mark Murphy's books about Android programming and I am having trouble understanding some things about services. As I understand it there are local and remote services that I can create. However, what I don't understand are the use cases for when you would use one over the other. Here's basically what I need to do and I'm not sure about which service type to use. I want to create an application and a homescreen widget that both get data from a service. I had in mind a service where the application and the widget could register a callback with the service to get data updates. Is that best done by a remote or a local service, or does it matter? Can either one be used? Any hints or tips would be great. Oh, if it matters the app, widget, and service will be in a single apk.

RE: [android-developers] Question about services
I think a local service would work fine. Basically create another class in your android project, extend Service, do your stuff, then send a broadcast from your service. In your activity you will want to register a broadcast receiver that listens for that broadcast from the service. In the onReceive event of the Broadcast Receiver execute whatever code you need to once the service responds. You can set the service up to send different broadcasts for different actions. -Original Message- From: android-developers@googlegroups.com [mailto:android-develop...@googlegroups.com] On Behalf Of Isaac Wagner Sent: Tuesday, November 30, 2010 1:01 PM To: android-developers@googlegroups.com Subject: [android-developers] Question about services I've been reading Mark Murphy's books about Android programming and I am having trouble understanding some things about services.

Re: [android-developers] Change Relative layout background dynamically Issues
Post your logcat output and the part of your layout xml file where you declare the RelativeLayout. I would guess that you either didn't assign an android:id to the relative layout, or using the wrong id with findViewById. Because of this, the value of background is null. -- Kostya 30.11.2010 20:57, Tommy пишет: Hi everyone. I have a relative layout that I want to change the background according to a set of features.
