[android-developers] Re: One process, two live Application objects?
On Dec 19, 8:18 pm, Y2i yur...@gmail.com wrote: Hm, so when do you need to just have code start running in your process first thing? Generally it needs to run for something else -- and that something else needs to make a call somewhere to get what it wants. Having that call Singleton.getInstance(context) (at which point you can do init for the first call) isn't any harder that ((Singleton)context.getApplication()), and it has some significant benefits: When some activity makes a first call to Singleton.getInstance(context), the singleton presumably will keep a reference to the context, directly or transitively; otherwise there would be no need to pass the context. No, Diane is saying that you can say Singleton.getInstance(context.getApplication()) to pass the Application reference to the singleton and it will be used to initialize the singleton if not already. The situation where all of Diane's suggestions don't work is the case where you want said singleton to be accessible from an object that doesn't have access to any kind of Context. If the getter for the singleton requires an Application, then you have to have ensure that the singleton was created ahead of time and instead pass null or provide another getter that doesn't take an Application. Specifically, the case for me where Application.onCreate() is necessary is initializing singletons in this way. I have a lot of non- Android java code that hide the details of being run inside or outside of Android, and singletons are no exception. If running in Android, I want a version of my singleton to use a context. If not Android, a version with no context (something else). I need the Application.onCreate() entry point to establish this configuration for me or be forced to put that line of init code into every component's onCreate, which is horrible. Also, I like Application.onCreate to set up background threads to kick off work that need not impede the user's progress through the app. Again, horrible to do that in every component.

[android-developers] Re: Help for dynamic views in Social Networking Application
I think you are a bit confused about design concepts. My humble suggestion to you is, your server should provide only the data. Your app should be fully responsible for defining and implementing the UI at the client side. What if you want to develop an app for iPhone/ iPad, Blackberry or Windows also (God forbid of course :-P )? Is your server going to define UIs for these clients as well? I don't think it's a good idea if you want to write native code. Unless of course if you want to implement an HTML based application.

[android-developers] Re: find word in faster speed
Don't forget there are more than data structures involved here. The method searching could be improved. As Jim suggested, breaking things down with an index (search for zulu beginning in the z section) could be sped up even more. Search for the last letter in the string first. By searching for that 4th character u first you've eliminated 3 other characters and can skip on to the next word. That way, similar words like zuch or zucchini won't slow you down matching the first two characters. Works even better for longer words.

[android-developers] GPS information with logcat
Hello, I’m trying to see if the assistance data is injected into the GPS by examining the logcat but I’m not able to know where the problem is. As I can see in logcat messages, Android fist tries to connect with the SUPL server but it fails, whereas the NTP time injection is well done. Finally, a xtra data download request is done (my devices has a Qualcomm chip) but there is no message to see whether it is well done or not. Logcat messages: // SUPL A-GPS D/GpsLocationProvider( 96): set_capabilities_callback: 7 D/ lib_locapi( 96): loc_eng_init called, client id = 0 D/ lib_locapi( 96): loc_eng_set_default_agps_server, type = 1, hostname = supl.google.com, port = 7276 D/lib_locapi( 96): loc_eng_process_deferred_action started D/lib_locapi( 96): Setting GPS privacy lock to RPC_LOC_LOCK_NONE D/lib_locapi( 96): loc_eng_set_gps_lock mode, client = 0, lock_type = 1 D/lib_locapi( 96): loc_eng_set_gps_lock mode failed // NTP D/GpsLocationProvider( 96): NTP server returned: 1306739478749 (Mon May 30 09:11:18 GMT+02:00 2011) reference: 38652 certainty: 73 system time offset: 12419 D/lib_locapi( 96): loc_eng_inject_time, uncertainty = 73 // XTRA DATA Qualcomm D/lib_locapi( 96): loc_event_cb: xtra download requst Is there any way to get more information related with the GPS behavior?

Re: [android-developers] Re: find word in faster speed
Three points. 1) Building the searching functionality twice is far more expensive than building it once, no matter what approach you use. Be sure that the performance of the DB approach is acceptable before you go and build it that way. 2) It can be quite challenging to get decent performance out of a database for something like this, depending on the functionality required. If, for example, you need real-time narrowing down of words, a database is going to be very slow (e.g. as you type letters, you get an alphabetized list of what's in the db). 3) There's probably an open source Trie out there somewhere that you can just use.

[android-developers] TextView ellipsize marquee on Ice Cream Sandwich
Hey there, I found something strange about ellipsize=marquee on my Galaxy Nexus...or better...it doesn't work. Instead of seeing nice fading edges at the end of the word (when the word doesn't fit the view of course), you get the normal dots (...). After some digging through the ICS source code I found, in the ViewConfiguration class, this (which enables/disables the fading edge for marquee): mFadingMarqueeEnabled = res.getBoolean(com.android.internal.R.bool.config_ui_enableFadingMarquee); For some reason on the Galaxy Nexus (Android 4.0.1) this is actually false. Do you have any idea on why is that? I also tried with Android 4.0.3 on the Nexus S, with the same results. As a test, I tried using Reflection to force the value of mFadingMarqueeEnabled to true. And while it does work in my own Activities, in doesn't work on AppWidgets (and that's where I'm actually using this). Do you know if it's actually possible somehow to change the boolean value of com.android.internal.R.bool.config_ui_enableFadingMarquee? (I believe not... :( ) On the emulator (tested both with Android 4.0 and 4.0.3) this is actually set to true. If you have an ICS device could you check if fading edges work for you? (a quick way to check this is to place on your homescreen an app with a long name - e.g. News Weather - and see if it shows .. at the end of the name, or if it fades nicely).

Re: [android-developers] Re: Is it possible to use the UI controls while the ProgressDialog is on?
Um, unless I'm missing something...
You can't use the same button because presumably the button to launch
the long-running operation is not in the dialog, it's in the activity
- and dialogs prevent interaction with activity UI elements while
displayed.
What you can do is one of:
1) Build your own dialog with a cancel button;
2) Use Dialog.setOnCancelListener which gets called if the user
presses the Back key; here the dialog is dismissed automatically;
3) Set a key listener in the dialog and check for when the back key is
pressed, something like:
mProgressDialog = new ProgressDialog(mActivity);
mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
mProgressDialog.setMax(item.fetch_decoded_size / 1024);
mProgressDialog.setTitle(R.string.attachment_dialog_title);
mProgressDialog.setCancelable(false);
mProgressDialog.setOnKeyListener(new OnKeyListener() {
@Override
public boolean onKey(DialogInterface dialog,
int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK
event.getAction() ==
KeyEvent.ACTION_UP
event.getRepeatCount() == 0) {
cancelDownload();
return true;
}
return false;
}
});
In this code, canceling the operation can take some time, so I made
the dialog non-cancelable to be able display Canceling

Read through the docs and find examples on *those* independent parts then piece them together. - 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] Problem on button click
Hi, I have a very unique problem which is sort of difficult to describe. We have developed an application where we connect to a server on the first screen with a button click (call it button1 which can also cancel) using an asyncTask as given in this url: http://vikaskanani.wordpress.com/2011/08/03/android-proper-way-to-cancel-asynctask/ Upon connection to the server, the first screen transitions into the second screen through an intent call where we have a listview for which we have written clicklisteners. What happens is: 1. when we click button1 after the Async call is completed for cancelling, cancelling does not happens and the first screen transitions into the next screen. 2. And worse thing that happens is the uncancelled button click event of the first screen causes the listview clicklistener of the second screen to fire. Why does this happen? And can somebody give me any pointers to atleast stop the listview clicklistener from firing?

[android-developers] Re: question about lockscreens
well that was a very well considered response, thanks. you are probably right, undertaking a lockscreen right off the bat is probably not a good idea. you see, the reason why i wanted to develop one was so that i could make a passworded lockscreen, but the password would have only been a backup. The primary unlock method would have been whenever the application detects a specific RFID tag with NFC. i monkeyed around with the intents in your widgetlocker app (com.teslacoilsw.widgetlocker.UNLOCK) in an attempt to call that intent from NFC task launcher, but i couldnt make the intent work, so i figured i would just try to write my own, lol. 1. thanks, i will make learning how to run services my next task 2.yes, i meant my own activity, moveTaskToBack() will probably work perfectly. On Dec 18, 3:30 pm, Kevin TeslaCoil Software ke...@teslacoilsw.com wrote: But does this mean that you guys are opposed to well known apps such as WidgetLocker, or Lockscreen Agenda? Well I'm the developer of WidgetLocker, so I'm not opposed to it at all :P. But this list is about developing apps that following the documentation, guidelines and restrictions of the SDK. WidgetLocker does not. I know it's hypocritical but I recommend other app devs, especially ones just starting, follow the SDK. It's safer and easier, and (mostly) protects you from fragmentation (I test against ~20 devices. I still need more). As you noticed, this list isn't very helpful if you chose to ignore the SDK rules. I imagine most devs that do, including myself, don't discuss it much. If you choose to ignore them, you're on your own. I wish to make an app that acts as a lockscreen. it would disable the home button, disable the back button, and then it would dismiss itself upon a successful entry of a password. Implementing security in an app, rather than at the system level, is a huge task and well beyond the scope of this list. There isn't even anyone to discuss it with, as it has not been done. Find an app that implements security (Note: WidgetLocker does not. There is good reason.) and if you can't bypassing it in less than 5 minutes, you aren't trying hard enough. Android is designed to disallow apps from blocking other apps. Even ignoring the Home and recent apps buttons, what about an incoming call? Or a phone reboot? Or a SMS popup? Or any notification in the notification bar for that matter? Or a malicious app? Or a task killer? Or the system task killer? Or out of memory? Or a bug causing a force close? It certainly is possible to display a screen that prompts for a password and when the password is enter the screen disappears. But implementing it in a manner that is more than just a false sense of security is very different. I theorize that with root and/or a device admin and a slightly-to-incredibly awkward user experience it's possible, but even if that's true it's a lot of work and a lot of testing and I guarantee you'd run into fragmentation issues of trying to support Sense vs Blur vs TouchWiz vs Stock. A custom rom, rather than an app, definitely could do this, but again this list is not the place to discuss that (There's a firmware building/modifying list for that kind of thing). 1. how do i make an application launch when the screen is activated? ACTION_SCREEN_OFF and ACTION_SCREEN_ON broadcasts. You'll need a service running to receive them (not a manifest receiver). Also note that no app can start within 5 seconds of the Home button being pressed, so Home, screen off, screen on, and you're delayed. 2. what method does one call to dismiss an application? (for example, when a password is entered successfully) Your own activity you mean? finish() or moveTaskToBack(). -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: One process, two live Application objects?
No, Diane is saying that you can say Singleton.getInstance(context.getApplication()) to pass the Application reference to the singleton and it will be used to initialize the singleton if not already. No, Diane was clearly saying Singleton.getInstance(context) to pass context (not the application) reference to the singleton (and it will be used to initialize the singleton if not initialized already). And passing context of random activities to initialize a singleton will result in the problems described earlier. Consistently calling Singleton.getInstance(context.getApplicationContext()) or Singleton.getInstance(context.getApplication()) will avoid memory leaks and dead context problems, but the signature of the Singleton.getInstance(Context) does not ensure that the method will always be called with the application context as the parameter, which is not the best choice from API design perspective. Having a method Singleton.getInstance(Application) instead of Singleton.getInstance(Context) will ensure that no activity context will be used to initialize the Singleton object. But from API design perspective this method signature is not the best one because the actual parameter will only be used once and ignored all other times. Using new NormalObject(Application) instead of Singleton.getInstance(Application) is a cleaner API. Specifically, the case for me where Application.onCreate() is necessary is initializing singletons in this way. I have a lot of non- Android java code that hide the details of being run inside or outside of Android, and singletons are no exception. If running in Android, I want a version of my singleton to use a context. If not Android, a version with no context (something else). I need the Application.onCreate() entry point to establish this configuration for me or be forced to put that line of init code into every component's onCreate, which is horrible.

[android-developers] Re: 4.0 Action Bar - remove app title.
hmm, can't you just do SetTitle() on the ActionBar? On Dec 19, 1:56 pm, Nathan critter...@crittermap.com wrote: I looked here, but I didn't find it. I could have missed it: http://developer.android.com/intl/de/guide/topics/ui/actionbar.html In ICS, they can't display my entire app name anyway.

I can't localize resource with ID #0x1090044 (it's not in my R.java or
any other files) and I don't know what it should be. Maybe some
internal menu layout? I already also tried to clean the project. I
know that there are new desing rules for Android 4.0 ICS and using
Action Bar instead older menu, but I need this code get working even
on ICS for many different reasons. Should I some how edit this code to
work even on ICS? I also already tried creating menu from XML file
using this code with same exception.
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu, menu); //have different Res ID than
#0x1090044
Thank you for any advice!

[android-developers] Split Action Bar - Action Item disappear in landscape mode
I've got a split action bar working in my app. There are several action items and an overflow menu for the extra ones. However, when I rotate the device to landscape, the overflow (menu) button appears at the top action bar, and all the other action items disappear. All these menu items have always set for showAsAction. Is this the expected behavior? I was expecting all the actions on the split action bar to appear at the top action bar when in landscape mode.

[android-developers] Image rotation is not uniform across devices. ExifInterface.TAG_ORIENTATION returns 1 for all orientation on some pictures
This seems to be related to a bug I found on android issue database; http://code.google.com/p/android/issues/detail?id=19268 The above bug is that when taking pictures with intent ACTION_IMAGE_CAPTURE, it saves the image in the location specified in Extras bundle but it also saves the image in the gallery.. It seems that as a side effect of this bug, the image that's saved in the user specifed location is missing the orientation information while the one in the gallery is saved properly. This makes for a messy user experience since they can only take pictures in the sideways orientation or they need to take the picture then select it from the gallery on these devices.. I opened another issue regarding this here; http://code.google.com/p/android/issues/detail?id=22822 Also I have started a stackOverflow ticket that got no response (despite the fact that I put up some delicious bounty on it).

received a clear answer to it. It would be great if someone could help
me with this.

[android-developers] Did Intent.FLAG_ACTIVITY_SINGLE_TASK disappear ?
I have just noticed that parameter FLAG_ACTIVITY_SINGLE_TASK is no more available in the Android developer documentation: I am just trying to do this (removeCard in an Intent) removeCard.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TASK); startActivity(removeCard); I have already seen such a parameter in code found in Google but the Java compiler just tells me it does not exist. I am only able to start the main activity with this parameter but I have to configure the manifest file to perform this: android:launchMode = singleTask And this does not work for activities other than main activities launched upon app start. Does someone know why this parameter disappeared for Intent ? Regards, Apple92 -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Automation Tests for Sync Adapter
Hello All, I am writing a sync service using Sync Adapter framework in android. It works great, but I want to validate code with some automation testing. Right now, every time i need to test the sync code, I have to go to Emulator - Development Tools - Sync Tester and explicitly start sync service. I have gone through instrumentation tests of android framework but it did not seem to be helpful. What I ideally want to test is following - Register an observer with sync service - Fireup sync service - Once completed, validate the data in the database any help in this regard is greatly appreciated thanks, madhu -- You received this message because you are subscribed to the Google Groups Android Developers group.
