Android :: Creating An Object - Multiple Of Same Instance

Oct 19, 2010

I created an Matrix object (like the math Matrix, a 4x4 block of numbers for instance) and it works fine, can set row,col,variable just fine, but, I cant have more than one of the same object, I have it creating an ArrayList of a dozen Matrix objects, each with the three variables, but when I call changeVar(Matrix x,int variable) and refresh the printout of the matrix, it changes all of the numbers to what i changed the variable to. So it looks like its just creating the same instance over and over, and if you change one, it changes them all, am i missing anything obvious?

HTC Magic :: Wifi Priority - Multi Tasking To Switch Between Applications?

Jul 22, 2009

Just two quick questions: When connected to wifi, do internet connections made on the device automatically go via wifi as opposed to 3g etc and if not then is there a way to organize which wireless connection 'methods' have higher priority (i am worried about excessive data costs). Second question is: Is there any multi tasking support on the Magic and if so then how do you switch between applications?

I am learning the app widget programming in the 1.5 SDK release. I was playing with the sample widget (wiktionary) and found out that you can actually add multiple instance of the same widget to the home screen, is there a way to prevent this? An attribute in the XML? I am stuck with 3 instance of wikitonary and 2 instances of music player on my emulator now... can't get rid of them... :(Also I am looking into buliding my own app widget container, not a home screen replacement, just a container that can host other widgets, I read the appwidgethost api doc, is there any sample code or guide on how to use the appwidgethost api

HTC Incredible :: Phone Keeps Shutting Off While Using Multiple Applications At Once?

Oct 14, 2010

My phone seems to shut off or start a reboot loop when I either multitask and use multiple apps at once or when I attempt to do something that is data intensive such as stream a video. It then either just boots up and once it gets to the home screen then reboots again or sometimes the phone will shut off, vibrate multiple times, then the green LED will start to blink. Once this happens the only way to get it turn on again is to pull the battery. I was using the stock 2.2 froyo with no issues until this randomly started to happen about a week ago. I thought it might be an issue with the rom so now I am currently running the 2.2 with the Uncommon 1.1 rom, baseband:, kernel: htc-kernel@and18-2 #1, build number 3.21.605.1 CL231334 release keys.

HTC Incredible :: Google Applications Setup Through Exchange Multiple Calendars

Aug 25, 2010

I setup a Google Apps domain and I want to connect it to my Incredible via Exchange. Sounds easy enough. All works well, except if you create multiple calendars within Google Apps. It only sees and sync the main Exchange Calendar. Does anyone know of a fix for this? I am setting this up for a business user who wants to maintain two different contact lists. The exchange list will be for business only and the Gmail account used to setup the phone is all personal (has multiple calendars too).

I thought I could add the Google Apps account as a Google account in addition to exchange, but that only enables contact and mail sync. No option for Calendar. Does anyone have a work around. I am using my phone as a test prior to launching on my clients. I did a factory reset and used the Apps Account as the main account on setup, but now I will not be able to re-install already paid for apps from the Market.

Android :: Inter Connectivity / Running Multiple Applications On Android

Jul 12, 2010

Is it possible to run multiple apps at the same time on Android? I have an app that has two separate layers and which they are normally launched separately. They open sockets and talk to each other via those sockets. I am not sure if this would be possible under Android - may be generate two separate projects and their corresponding UIs and then launch them at the same time. If that is not possible I am assuming I will need to launch them from the same UI - their interprocess sockets should be able to connect to each other. Is this something that is worth pursuing?

Android :: Service Thread Priority

Dec 16, 2009

I have two apps that use a service to upload and download files and data. I've noticed that when the service gets very busy, it can cause the UI to block, up to the point that Android shows a "force quit/ wait" popup. In order to avoid that, I run tasks in a service at a lower priority. This way, the service will never cause the UI to hickup. Also, the service stops if the app hasn't been used for a certain number of minutes. I don't want to keep resources if the user isn't using my app.I have found that some of my users run apps that run services permanently at normal priority. Such a service starts at phone switch on, and keeps running indefinitely, downloading vast amounts of data. My policy of being nice to other apps doesn't pay off: these agressive third party services push my service away so it never gets anything done. As one of my users told me, my app has hickups, until he kills the service of this app X, after which my app runs smoothly, snappy, and fast.

My question is, should I be nice to other apps and to the UI in my own app, or should I just run a service and agressively take all resources I need - or don't need? This is one issue where Android is different from iPhone. We can run services, but by doing so, we can cause damage to other peoples apps. Of course, my "question" doesn't require an answer. I'm just curious after what other people think, what your experience here is.

Android :: Increasing Priority Of Activity

May 14, 2010

Let me say this with an example. Lets say, my activity A is being executed, meanwhile another activity B gets launched. By default, acivity B will come on top of activity A. My requirement is that I want to keep A on top. Only activities such as phone, lock screen and home screen can come on top of me not other activities unless my activity closes.

Android :: Setting Priority For Service

Aug 13, 2010

Is there a standard way in Android to create an unkillable service with very high priority, assuming you have complete access to the device (as in you're building your own device on something like a beagleboard, not just installing an app)? I'm playing around with sip phone stuff, and it seems like just doing it as an app isn't going to work if you want high voice quality. (Assuming you want to be able to let the user switch away from the actual sip app and use different apps; all the sip phones I've tried have failed to maintain decent audio if you're multitasking.) Or would you just run the phonecall software outside Android in a normal Linux process and communicate with Android apps over sockets?

Android :: Internet Connection Priority

Oct 27, 2010

I am a newbie to Android so please excuse me if this is a silly question or one that has been answered many times before. When connecting to and using the Internet, I am trying to find out what determines the connection that the phone will use when more than one connection is available: Wifi, 3G etc. Is there a standard priority order for connection and use? can the user set the priority order? Usually I would expect the wifi connection to be preferred for reasons of speed and cost. I have looked at my phone user guide and the official Android user guide but cannot find any information about this.

Android :: Set Priority To Broadcast Receiver

Oct 24, 2010

The symptom: I have a broadcast receiver that listen to sms, when a sms is received, i call an activity to display. It works all fine if the screen is on and not locked. But when screen is locked, and as soon as i received the sms, the activity popup for a second then disappeared and I use the code to unlock the screen.

getWindow().addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED | WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);

I think it might be the competitions with phone default sms program (the sms default program shows a notification only). I am wondering is there a way to set priority to broadcast receivers or even the activity that receiver stared, to avoid the conflicts between multiple receivers. or set orders to execute one by one? I have tried to thread.sleep my receiver for a second, still not working.

Android :: Threadpool With Good Priority

Aug 24, 2010

So from what I've known, if I do an AsyncTask inside an Activity, the task may be killed when user quits the Activity before it is finished. One solution I've seen is using IntentService, which the system will try hard not to kill. My problem is that IntentService only uses one background thread to run all the tasks one by one. I have several independent tasks that I wish to run concurrently, and that makes a difference in the UI (not serious, but could surprise user). How do I accomplish this? I imagine I could have several IntentService but this seems awkward and not scalable. How do I maintain sort of a threadpool that has a good priority, so that it won't get killed to easily by the system? If I start a (normal) Service, then launch some AsyncTasks within there, does that result in a higher priority?

Android :: Gmail Priority Inbox Notifications

Sep 2, 2010

Does anyone know how to set it so that my Android phone only notifies me when I get a message in my "Priority Inbox" (the new feature Google just launched in case you don't know what it is)?With my email I receive a bunch of newsletters, so instead of being notified every time one of them arrives I'd like to be notified only when messages in my Priority Inbox arrive.Being able to be alerted to messages with certain labels only would also work.

Android :: Application Priority - Graphics Stutter

Nov 18, 2009

I have an app which within the main Activity a SensorListener is setup. The listener detects changes from the accelerometer and sends updates to various child views, which update the display. When the app first start up, it's great - the graphics are smooth and the sensor notifications are immediately reflected in the views. Then after a few minutes it starts to stutter, making the display very jerky - and for the purpose of this app quite unusable. I've done some logging and the sensor updates are still being passed, but they start stacking up and all get sent in batches. It's like the system has put this app down the priority list after it's been running a while. I've added some garbage collecting but it only seemed to help a little. What could be happening here? How can I try and keep this app at the top of the priority list?

Android :: Set Thread Priority Of Media Player

Feb 9, 2010

I am programming a game with fast graphics. The MediaPlayer is stuttering sometimes. When I have the MediaPlayer in a service, it does not stutter, but some people here adviced me not to use services if they should stop automatically when the user ends my application. So how can I set the thread-priority of the MediaPlayer-Object? SoundPool uses the MediaPlayer and with SoundPool, you can set the thread-priority, but I cannot add my audio-file to SoundPool, because its size is about 2mb (too big for SoundPool). I can lower my main-thread-priority so that the MediaPlayer has a relatively higher priority, but isn't this a bad idea?

Android :: Change Broadcast Receiver Priority

May 5, 2009

I have developed a music player and the application defines a broadcast receiver that handles MediaButton intents:

<receiver android:name="MediaButtonIntentReceiver"> <intent-filter android:priority="32000"> <action android:name="android.intent.action.MEDIA_BUTTON"/> </intent-filter> </receiver>

which works well. My question is if it was possible to change the priority of this receiver from within the settings activity of my application. That way people could choose if they wanted my player as default handler of the headset buttons or not.

Android :: Set And Get Thread Priority From Java And Native Layers?

May 10, 2010

I have a multithreaded streaming app which has mainly the following 5 threads. 1 Main App(UI) Thread 1 controller thread (in native) 1 audio decoder thread (in native) 1 video decoder thread(in native) 1 thread to query the head position of audio (in Java) Apart from this I have video rendering with OpenGL. My problem is, if I query the thread priority using the Thread.getPriority method (my native threads make callbacks to Java and I am making the query at that point of time), I am getting the priority of each of them as 5. For my audio query thread (the last one in the list) I am explicitly setting the priority using Process.setThreadPriority(Process.THREAD_PRIORITY_URGENT_AUDIO); Also for my decoder threads, I am giving higher priority than my controller thread(using pthread APIs in native). But still finally all of them seem to have same priority. Also what should I be doing to increase the priority of my threads(both from Java and native)?

Android :: Setting Connection Priorities Using Wifi Configuration Priority

May 20, 2009

I am trying to to use WiFi API to set priorities to created profiles. I am using the priority field of WifiConfiguration to set this information. I have found out that no matter what priority I set, Android always tries to re-connect to the latest access point that it was connected to. Here is what I do: 1) I create a profile A with a very low priority (0) 2) I create a profile B with high priority (100) 3) I connect to profile A 4) I turn Wi-Fi off 5) I turn Wi-Fi back on 6) In the scan Android sees both A & B 7) Android connects to A, even though its priority is much lower. Does anyone has a work around for this?
