Re: [android-developers] AlarmManager vs BroadcastReceiver vs Service
Thanks TreKing - I get it, the Alarm Receiver is kind of a redundant step if all it does is start the Service. But it's not 'wrong' as such. To the other point, is there actually a way to lauch an app without a main activity? I had read it wasn't possible, and when I tried to do so from AndroidStudio I just got errors, and didn't look at it any further. Is there an example anywhere that you know of?

[android-developers] AlarmManager vs BroadcastReceiver vs Service
Hi. I need a background task to run every minute. I have no need for a user interface, although I understand that I must still declare a launcher activity, which I can just finish() once I've set up my service. I'm confused between the use of AlarmManager, Receivers and Services. So far, I've scheduled a repeating alarm, which passes a class called AlarmReceiver in its Intent. AlarmReceiver extends BroadcastReceiver, and the onReceive() method successfully fires every minute, even if I kill the activity, which is exactly what I want. However, at no point am I using a class which extends Service or IntentService, which when I look around at other people's examples, seems to be what everyone does when they want a task to run as a background service. Am I doing something wrong? Should I be calling a Service class from my BroadcastReceiver instead of doing the work there?

[android-developers] Android build and target versions
I've seen various questions related to the different between the minSdkVersion and the targetSdkVersion, and I understand the principle here. My question is more related to how you handle new android versions, and what you should specify then. Scenario: I built my app a year ago, when 2.3.3 (level 10) was out, and wanted to support back to 1.6 (level 4). So my manifest stated: uses-sdk android:minSdkVersion=4 android:targetSdkVersion=10 / Also, in my Eclipse setup, I specified that the project should be built using 2.3.3 Now, there are several newer versions available, up to 4.0.3 (level 15). I want my app to be available to all possible devices, and as far as I can tell this seems to be the case. At this moment in time, I don't require any extra features that the newer APIs offer. Should I update my project to build with the newer version? Should I change the targetSdkVersion? If I don't change it, are there any drawbacks?

[android-developers] Re: Android build and target versions
Thanks TreKing. I hoped this was the case, and for most of my apps this seemed to be what was happening. I've actually been meaning to ask this for some time... but what prompted me to ask now is that one app is not appearing in the market for users of ICS. There's nothing in the manifest of this app which is really any different from the others, so do you have any idea why an app wouldn't show up in the market for ICS? All my other apps, with similar manifest declerations, do show up in the market.

[android-developers] Multiple apps contained within one project
Hi all, I have a situation where I am to produce applications for multiple clients, all based on the same functionality. Essentially, each app will be the same apart from content - text elements and images. It would make sense for me to keep this as one project in Eclipse. I can set a property somewhere (clientName for example) which would enable me to pull in the required content and images accordingly. I think this would be manageable. The main problem is when I want to build the apps to go live.- they are all to be separate releases. Does this mean that they will all need their own package identifier? And their own manifest file? My solution above would mean that they would all have the same structure. Has anyone come across this issue before? I'd value any thoughts on how I could maintain and build these projects.

[android-developers] Default screen orientation problem with sensor events
Hi all. I've researched various threads where people ask how you get the default screen orientation (i.e. tablets vs standard portrait devices) but the general answer seems to be that there isn't a way to do this, and that there shouldn't be - i.e. you build your app to suit the orientation you want, or you let the user decide. However, I have a problem. One of my apps uses the SensorEventListener to get an angle, from which I make some calculations and display some graphics. A Motorola Xoom users has told me that my app is 180 degrees out. So clearly this device is returning different sensor values to all the devices I've tested on. I'm making the assumption that it's because it's a tablet, and I need to adjust my calculations accordingly. But I can't find a way to get this information from the device. Or - maybe my assumption is wrong, and there's another reason why the Xoom returns different sensor values? Any thoughts on this appreciated. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Soft keyboard issue
Yet another soft keyboard issue...! I start an activity with the following flags: android:windowSoftInputMode=stateHidden|adjustPan This means that upon startup, the soft keyboard is not displayed. Clicking into the EditText brings up the keyboard as expected. From this activity, I open up a new activity (containing a webview which loads an external site, but I think that's irrelevant), then when the transaction is complete it finishes and returns to the original activity. Once back, the soft keyboard will not display any more.

[android-developers] Re: Strange webview problem
Mark, thanks for looking into this. At least there is an issue, and it's not just me going bonkers. I've been looking at it further, and it seems to be somehow related to the WebView not liking list item (li) tags. I've built a temporary work around into my code, simply by doing a text replacement which, when displayed, has the correct layout effect: content = content.replaceAll(ul, ); content = content.replaceAll(/ul, ); content = content.replaceAll(/li, br/); content = content.replaceAll(li, nbsp;nbsp;nbsp;#9679;nbsp;nbsp;); Any list item bullet points are simply replaced by an alternative means of display. However, this isn't of course a solution. This is a rather ugly and expensive hack! On Dec 19, 1:39 pm, Mark Murphy mmur...@commonsware.com wrote: Well, I can certainly reproduce the problem now. In fact, it's worse than you feared -- it will not reliably display even the first time on a Nexus S with Android 4.0. (sidebar: Nexus S with Android 4.0! Who-hoo!) On a Nexus One with Android 2.3.x, I could only reproduce the problem by pressing BACK, then using recent-tasks to go back to the app. Since the symptoms are akin to what I was seeing with the rotation scenario, my guess is that the issue is somehow tied to creating a second WebView within the same process. Unfortunately, while that can be worked around for configuration changes (per my previous email), I know of no solution here.

[android-developers] Re: Strange webview problem
Mark, thanks for looking into this. Unfortunately this has nothing to do with orientation. My app is only in portrait mode - apologies I should have supplied the manifest to make that clear. So I'm not sure any of the things you've mentioned are going to alter the issue. I've used fill_parent and added the manifest line anyway, but the behaviour is still the same. The webview content just disappears. Please could you try it again in portrait mode only?

For example, after an orientation change, I wound up with a zero-height WebView. That being said, even if i set the height to fill_parent, I am definitely seeing strange behavior with the WebView with your supplied content. Adding android:configChanges=orientation|keyboardHidden to the activity seems to clear up the problem, presumably because it keeps the same WebView.

I've just realised it's the method HTML.fromHTML() that's causing the delay. Removing that and just calling setText(myText) renders it instantly. Problem is, the content is marked up.

If just displaying the Text is taking that long, then a progress dialog is not going to do you much good as the displaying happens on the GUI thread, which you would be blocking, preventing the progress dialog from animating. An idea: If you can't optimize out the display, look at reducing how much you set on the TextView initially. Reduce the size of the string to start with then append more and more to it via an AsyncTask / Handler or something. - TreKing http://sites.google.com/site/rezmobileapps/treking - Chicago transit tracking app for Android-powered devices -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Android C2DM question
Hi all, I'm currently weighing up the options for push notifications in my app. 1) Polling. I could use a boot receiver / alarm manager combination to fire off a process which checks our server periodically, say every 15 minutes, and then immediately terminates. First question is, is this resource hungry? I can't believe it would make any noticeable difference... 2) Urban Airship. I'm put off using this as their site says it doesn't work if the app is mounted on the external storage. As our app is likely to contain significant (many megabytes of) assets, this probably isn't the best option. 3) C2DM. Can anyone confirm if this works when the app is stored on the SD Card? I'm just curious, as even though Urban Airship uses the C2DM protocol to send the notifications, it isn't able to in this instance.

[android-developers] Re: Directing user to webpage, then back to app
Ok, I have a related, but unrelated, question about this! More about managing Activities and Intents, but within the above scenario. Let's say my app has started ActivityA, ActivityB, and ActivityC. This last activity opens the browser, which does its stuff until the user clicks the link (discussed above) which returns the user to my app, but in the case a new ActivityD. The small issue I have here is that the browser activity remains in the stack. Ideally I want it finished somehow. Even if I go from ActivityD back to ActivityC (setting Intent.FLAG_ACTIVITY_PREVIOUS_IS_TOP), the browser activity is still next in line. Once I've returned to C, I want to be able to continue as if the browser had never opened, back to B and then A etc. Can this be achieved? -- You received this message because you are subscribed to the Google Groups Android Developers group.

Yes I rather thought that would be the case. Unfortunately I don't think the 'intent' link works from within a WebView, so I'm stuck with the browser, which would probably be the client's preference anyway. I don't want to actually 'get rid' of the browser as such, rather just move it to the other end of the stack. I assume you can't get hold of the stack and manipulate it like a pack of cards?!

Or consolidate your app such that there is simply one Activity ABCD where you are handling your own back stack (e.g., using dynamic fragments), with an Intent triggered by the browser that includes FLAG_ACTIVITY_REORDER_TO_FRONT, so the existing ABCD instance is reused and you get the Intent in onNewIntent(). -- Mark Murphy (a Commons Guy)http://commonsware.com|http://github.com/commonsguyhttp://commonsware.com/blog|http://twitter.com/commonsguy _Android Programming Tutorials_ Version 4.1 Available! -- You received this message because you are subscribed to the Google Groups Android Developers group.

Thanks Mark. Now that I know what to be searching for, I've found several similar topics mostly on stackoverflow.

I don't get this bit: The best way to use this, if you want to ensure it launches only your app, is with your own scoped action and using Intent.setPackage() to say the Intent will only match your app package. and also... Finally, you may want to set the package of the intent to your app with this: http://developer.android.com/reference/android/content/Intent.html#setPackage(java.lang.String) This is a newer feature in the platform, which allows you to direct link intents to only your app so that other applications can not intercept and handle them.

[android-developers] Converting to xlarge layouts
Hi all. I'm altering my app so that it fits nicely into a tablet, by specifing layout-xlarge and drawable-xlarge resources. One thing I don't seem to be able to alter is the dialogs. I have a number of these in my code: AlertDialog.Builder alert = new AlertDialog.Builder(MyActivity.this); alert.setTitle(R.string.dialog_title); alert.setIcon(R.drawable.icon); alert.setMessage(R.string.dialog_desc); // add some buttons and actions alert.show(); These are appearing very small, with tiny text, and don't seem to be being re-sized according to the device type. How can I achieve this please? I'm using the standard emulator for testing this, by the way. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Different ACTION_CALL intents

[android-developers] Re: AlarmManager - list of alarms set?
Hi Kostya. This is basically a revival of this old thread, in which you helped me some time ago. http://groups.google.com/group/android-developers/browse_thread/thread/b2abad03be3467c0/d73f3780fbdd08f9 In my case, the onReceive method calls an ASyncTask which does some network calls, so continues on for longer than the life of onReceive(). I've implemented a Wakelock in my Receiver as you suggested, which releases the lock once the network task has done its stuff. However, the process *still* sometimes dies before it gets as far as releasing the lock. It's definitely better now, just not 100% reliable. It's fine on 'good' phones, but on those with lower memory capabilities (HTC Hero, Samsung Galaxy Europa for example) I still get this problem. There's no errors, I'm sure of that, it's just being killed before the task has completed. On Jun 30, 10:31 am, Kostya Vasilyev kmans...@gmail.com wrote: There isn't.

[android-developers] Re: AlarmManager - list of alarms set?
One of the problems with setting the alarm immediately inside onReceive(), is that the time of the next alarm depends on the outcome of the task. So I could set a default one, but what happens if I set it twice? Does the second overwrite the first, or will I end up with two alarms? On Jun 30, 11:29 am, Kostya Vasilyev kmans...@gmail.com wrote: Neil, A running AsyncTask does not make your process less likely to be killed. Two possible fixes: - Use a service with startForeground to that Android (and the user) knows that your application is doing something important and doesn't kill the process. You can leverage IntentService or Mark Murphy's WakefulIntentService to make it easier. - Set the next alarm right inside onReceive of the current one. or perhaps both fixes, if both the scheduling and the completion of each work item are important. FWIW, I have code in my current project that uses the second approach, and don't have a problem even with devices that have a very aggressive process killing scheme (one of those is the original 7 Galaxy Tab with Android 2.3). -- Kostya -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Alternative to radio buttons?
I have this situation quite often, and simply stick to three ImageButtons. It means you need pressed and static states for each button, controlled by an xml selector as the drawable, and of course you have to manage the states yourself, i.e. set the pressed button as 'pressed' and the other two as static. If you go down this route, manage the states in a runnable which fires about 100millis after the press, so that the default button 'up' action doesn't undo your work.

[android-developers] Re: Need to create Android toggle button in Iphone style
Although the original question perhaps wasn't asked in the best way, this is actually a good point, something that I'm looking into myself. It's a sad fact that in the Android world many clients are now asking for an app that does what the existing iPhone app does. And iPhone apps that I'm basing my Android apps on all have these 'switcher' style toggle buttons. You can slide a button between two choices, like an old style analogue hifi switch between AM and FM, for example. The Android ToggleButton doesn't actually give the same behaviour - it's an On or Off state, which isn't the same as choosing between two different options. If I want to ask the user (using the same example) if they want to listen to AM or FM, it would be good to have one switch, rather than a space consuming radio group. Yes I know I could design a button which gets switched when pressed, but it still isn't the same.

[android-developers] Getting bitmap to fit an ImageView

[android-developers] Memory managing my list adapter
Hi all. I have a list adapter, code given below. I'm trying to clean up the app, recycle bitmaps etc, to lower the memory usage as I've been experiencing out of memory issues when creating bitmaps. I'm concerned that my list adapter is not as efficient as it could be, and just wanted some advice. 1) As I scroll up and down the list, I notice that getView() gets called each time the item appears. Thus, it creates another ImageView which gets assigned another bitmap. Is there not a way to have this only called the once, so that the next time the list row is called, it's already instantiated and doesn't need to re-inflate the layout? 2) Once my activity finishes, is there a way I can access the ImageView items created by the list adapter, and clean them all up? By this I mean, set the image resource to null, so no bitmaps are still being referenced.

Eventually it does run out of memory yes, if I force it... for example
if I switch activities back and forward, so the list view keeps
getting created, eventually I get the awful BM exceeds virtual
memory or suchlike error. It's probably not likely to happen under
normal use, but obviously I'd like to stop it ever happening if
possible. And the people testing the app will certainly encounter
it...
I'll try what you suggest, thanks.

It does - your code already reuses convertView, so it does not create a

The only issue then is that this can end up with lots of image objects
in memory, which are somewhat slow to recycle. You could keep track of
them yourself (preferably with WeakReference) and call recycle() at some
point.
Does your code actually run out of memory? If not, I'd just let it be.

[android-developers] Re: Memory managing my list adapter
Yes I think you're right. What's happening here is that activities are starting up over existing instances of the same activity. So for example, this app has four menu options, each of which start a new activity. If the user clicks menu option A, activity A starts. Then, if option B is clicked, activity B starts. Then, on selecting option A again, a new activity A starts. So when you click 'back', rather than the app finishing after one or two presses, you end up retracing your route back through A, B, A, B, A etc. Clearly there's something wrong with my design here, but I'm not sure how I handle this. I can prevent it from opening Activity A if this is the one that's already displayed - but how can I resume an existing version of the activity, if it exists, after another activity has come to the fore? All I can think of is keeping some kind of record of the activities created, and 'controlling' them by finishing all the subsequent activities until I get back to the one requested. Surely that would be bad - that's what Android is supposed to do for me?

Ok, I'll try again - it was a Sunday after all :-) Basically all I'm after is a LinearLayout sitting in the center of the screen, that I can scroll horizontally from one item to the next, using a finger scroll, rather than just buttons.

[android-developers] Custom map overlays
Hi all. I'm fairly familiar with ItemizedOverlay and OverlayItem classes, where you pass a drawable to the Overlay which gets added to the MapOverlays and displayed on the map. However I want to create a view, using an XML layout, and add this to the map in the same way as an overlay. So instead of displaying a simple image, I want to add a view which has more useful info to show - but is still in a fixed position on the map and moves with it accordingly. Any pointers appreciated... thanks. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Layout help
Hi all. I'm struggling with a layout... would appreciate any suggestions on how to handle this. Basically, I have a list of objects. Each has attributes (like Name) and an image. I want to display the objects in a gallery style, allowing the user to scroll / fling from one item to the next. The tricky bits I'm facing are: - I want the gallery overall to sit within a static outer frame (i.e. my main.xml), so that the gallery itself is not full screen. - I want each item within the gallery to be controlled via its own xml layout (i.e. the same layout applied to each item). - I want only one item to be displayed at a time. I've been playing around with various Gallery examples, but the items merge into a row rather than being filling the enclosing parent. I've also been trying the FlingGallery which has been posted here before, but can't get that to work within an enclosing layout via xml file. I'm sure this is simpler than I'm making it out to be - any ideas? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Scheduling ideas
Yes sorry, bad wording, not an activity as such.
My AlarmReceiver has one method, onReceive(), which starts an
ASyncTask - that in turn does a server call, then schedules the next
alarm.
On Feb 24, 8:50 pm, Kostya Vasilyev kmans...@gmail.com wrote:
Ok, that's a receiver.
I am guessing that your receiver uses startActivity. If you do that,
beware of sleep/wake states, it's documented here:
http://developer.android.com/reference/android/app/AlarmManager.html
Android guarantees that for Wakeup-type alarms delivered to a broadcast
receiver, it will keep the device from falling back to sleep only for
the duration of the receiver's onReceive.
If that's too short, and your code needs to do more, especially an
asynchronous operation (such as starting an Activity or a Service), then
it's up to your code to acquire a WakeLock to keep the device awake as
long as needed for that.
There is an example at the top of this page:
http://developer.android.com/reference/android/os/PowerManager.html
Basically, the structure should be -
onReceive()
Call startService or startActivity
Acquire a WakeLock
[return]
--- lock is held, device is still awake ---
Android processes startActivity call
Your activity is created and started
onResume releases the wake lock so it's not held forever
Somewhere in there should be some kind of error handling, so that if
something goes wrong, the device is not held awake indefinitely (or
rather, until the battery runs out - which won't be long).

Reviving this thread yet again...
There does seem to be some kind of bug in the code. Strange thing is
though, it does get caught. The code always works fine within normal
circumstances, but when it's run as an Alarm Service, the process dies
at a particular line, and it isn't caught in the catch block.
try{
URL updateURL = new URL(sUrl);
conn = updateURL.openConnection();
ins = conn.getInputStream(); // this line causes the process
to die
}catch(IOException ioe){
Log.e(TAG, Error making URL request + ioe.getMessage()); //
this is never shown
throw ioe;
}
Any ideas why this would happen?
On Feb 7, 9:41 am, Kostya Vasilyev kmans...@gmail.com wrote:
Having said that, there may be a bug in your code. Since your code,
AFAIK, schedules one alarm at a time, there may be a situation where the
old alarm already fired (and forgotten), and the new one isn't
scheduled. You should schedule the new alarm as soon as you receive the
old one. Ideally, right inside onReceive for the old alarm's broadcast
action, because onReceive is guaranteed to not be interrupted.

Ok. I think I may have found one factor influencing this. I'm using ASyncTask to handle the thread.

Hi Mark, thanks for response. I like your last comment, you're thinking on the same lines as me :-) Your step1 - are you thinking of code in the HTML that's loaded into the webview, or Android code which can catch these events? Another thing I've thought of: The problem can be solved by 'pinching' the screen to resize it slightly. As soon as it's been resized, the keyboard works. I wondered if it's possible to programmatically resize the screen as if the user 'pinched' it? On Feb 19, 1:19 pm, Mark Murphy mmur...@commonsware.com wrote: Sounds like a device bug. The following solution is extremely theoretical: Step #1: Add Javascript event handling to your code to find out when a field gets focus.

Step #3: For known problematic devices, have your Java object manually pop up the input method editor via InputMethodManager. Be careful about problematic devices with side-slider keyboards -- you only want to display the soft keyboard when the physical keyboard is unavailable.

Hi Kostya.
Yes, the alarm gets called... it's just my own call which stops it
doing it's task. For example:
if(isNetworkAvailable(mContext)){
// do stuff...

public static boolean isNetworkAvailable(Context context) {
ConnectivityManager connMgr = (ConnectivityManager)
context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo info = connMgr.getActiveNetworkInfo();
return(info != null info.isConnected());

So this call tells me the network isn't available when the phone's
asleep. I guess I'll have to try another way of testing for the
network?

That's pretty much how I test too, except my code lacks a check for
isConnected, only for null.
This is what I get in my app's log:
NetworkInfo: type: MOBILE[EDGE], state: CONNECTED/CONNECTED, reason:
apnSwitched, extra: internet.mts.ru, roaming: false, failover: false,
isAvailable: true
Two ideas:
- Check your phone settings, perhaps yours has some kind of sleep policy
for mobile data;
- Log the value you get by calling getActiveNetworkInfo into a file, and
examine later.

Hi Kostya.
Yes, the alarm gets called... it's just my own call which stops it
doing it's task. For example:
if(isNetworkAvailable(mContext)){
// do stuff...
}
public static boolean isNetworkAvailable(Context context) {
ConnectivityManager connMgr = (ConnectivityManager)
context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo info = connMgr.getActiveNetworkInfo();
return(info != null info.isConnected());
}
So this call tells me the network isn't available when the phone's
asleep. I guess I'll have to try another way of testing for the
network?

Ok, one problem with this alarm service.
I schedule it for some time in the morning, and when I get up and
check the phone, the alarm didn't get called, because it thinks
there's no network connection.
I'm sure the alarm did get called, as the AlarmManager service has
nothing to do with networking.
This is a call I make deliberately (I always check there's a
connection before making the server request)... but why does it think
there's no network when the phone is 'sleeping'? The connection is
still there...
Depends on what kind of network connectivity you expect.
In my tests (Moto Milestone), WiFi doesn't get enabled when the phone is
woken by an alarm, but the cellular data connection is available
immediately.

[android-developers] Using Android C2DM
Hi everyone. I'm attempting to use C2DM in my app, but I admit I'm finding the docs very confusing. The official guide http://code.google.com/android/c2dm/ makes the process seem relatively simple, showing code which implements various methods, onReceive(), handleRegistration(), performs registration, along with some manifest entries. It also points to two examples, JumpNote and ChrometoPhone. However the implementation of C2DM in these two apps are not like the suggestions in the overview docs: - the docs declare a receiver: receiver android:name=.C2DMReceiver android:permission=com.google.android.c2dm.permission.SEND - while the sample apps do this: service android:name=.C2DMReceiver / receiver android:name=com.google.android.c2dm.C2DMBroadcastReceiver android:permission=com.google.android.c2dm.permission.SEND The samples also have a class called C2DMReceiver, but again the docs have no mention of this. Furthermore, I can find no implementation of the methods mentioned above (onReceive, handleRegistration) within the sample apps. Anyway, I've so far attempted to implement the code as per the docs, and so far the only output I get is this: DEBUG/C2DMRegistrar(184): [C2DMRegistrar.61] register: http error 400 Confused... any advice please? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Scheduling ideas
Hi all. I want to build certain functionality into my app, but I'm not sure if it's possible. The main parts of the app (and server calls) are built, it's just the scheduling I'm considering. 1) I want the app to check against a server at a set time each morning. If there are updates available (in this case it's just some data from a database) I want to either create a notification, or resume the app, loading up the new data. 2) I suppose if the device isn't turned on at the specified time, then it should check the next time it starts up to see if an update check is due. 3) I want this to be done in a way where the app isn't running, i.e. no drain on resources. So, can this be done, and what should I be looking at? Thanks. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Scheduling ideas
Thanks... this seems to be what I'm after. However I just put together a simple repeat alarm, outputting a Toast every minute, which was fine. But it didn't work again after a phone restart... how can this be implemented? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Scheduling ideas
Right, thanks. And will that stay on the device as long as the app is still installed? (And, I suppose, will it get removed if the app is uninstalled?)
