View 2 Replies View RelatedAndroid :: Safe To Keep Reference To A Thread In A Singleton?
Nov 15, 2010Let me give you the scenario.
Say that my first Activity that loads up, also creates a thread, which will run indefinitely in the background.
Now, if I move to another Activity, I assume that the thread that I initially created in the main activity will continue to run.
So, now to my main question - in order to manage this background thread from other Activities, is it safe to store a reference to that thread in a singleton object?

View 1 Replies View RelatedAndroid :: Is SQLiteStatement - Prepared Statement - Thread-safe?
Sep 20, 2010I'm wondering whether prepared statements in Android (instances of SQLiteStatement) are thread-safe. In particular I'm asking with regard to the following scenario:
In a ContentProvider you create a pre-compiled insert statement during onCreate. Then, in the overriden insert method you make use of this statement by binding a set of parameters to it and calling executeInsert on it.
We know that a ContentProvider has to be written in a thread-safe manner. If SQLiteStatement does not bind parameters per thread, a concurrent call to the provider's insert method would alter the statement's bindings and result in unpredictable behavior.
Android's own Contacts provider uses prepared statements in this way (http://bit.ly/bDuKAT), so I tend to believe that they are in fact thread-safe. Looking at the source code of SQLiteStatement I don't see how though (http://bit.ly/9M1Swv).
So, is SQLiteStatement (or SQLiteProgram that is) thread-safe with respect to parameter binding or not?

Open Source Android Toolkit?
Feb 13, 2012I am currently working on an open source collection of Android APIs that will be collected into a toolkit. Essentially, this toolkit is intended to ease coding pains for developers by simplifying things such as network operations, file operations, etc..
I already have a bunch of things planned, such as PHP POST and GET operations, POP3, IMAP, and SMTP operations, File management operations (creating files, downloading files, parsing files, etc...). What other kinds of operations do you all think could be simplified or even just want an alternative to?

Sep 4, 2009I am using embedded-linux for device which has Arch ARMv5 Speed 266MHZ, vfpu and 32bit bus, 32MB 133 Mhz DDR Ram. can you tell me which windowing system should I use,
1).QT for embedded linux
2). Android.
3). Other!
Well, I am using microwindows for last one year and not satisfied with it as it does not have BSP (Binary Space Partitionin) in its windowing system , No shared memory support for bitmaps. I think Microwindows is just optimized for memory-size not for speed.

Android :: Why Aren't The 2D Graphics API & UI Toolkit Hardware Accelerated?
Sep 16, 2010I've been developing Android application for quite awhile now. Please correct me if I'm wrong, but as far as I know the UI toolkit and 2D graphics API aren't hardware accelerated (the official documentation states that Canvas is not accelerated). I've found that most non- trivial animation or blending operations are painfully slow even on mid-level devices like a Droid, even after taking much time to optimize my code.
I'd like to know what the rationale is for not providing hardware support for these frameworks? Wouldn't it be possible to at least make it optional for vendors to implement support? Does anyone have any additional information about this issue?

Android : Handle Messages Between The Main Thread(the Deafult UI Related Thread) And The User Created Gamethread
May 21, 2009I am writing an application in which i need to handle messages between the main thread(the deafult UI related thread) and the user created Gamethread.
The requirement is like this.
An activity(say "Activity_X") is setting the view by "setContentView(some "View_Y")". In "Activity_X" i have implemeted "onCreateOptionsMenu()" and "onOptionsItemSelected()" fucntions for creating menus & a switch case for action to be taken on selecting those menus.Menu has items like "resume/pause/zoom/" .
All action to be take on selecting these menus are implemented in "View_Y" in a separate Gamethread by extending "Thread" class.
So whenever a menu is selected in "Activity_X" i need to send a message to "View_Y". And on receiving this ,a particular action/method should be called in View_Y(GameThread).
How can i achieve this using Handlers?Is there any other way of doing this? Please do share with me some code snippets for these.
