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?

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.

Android :: My Safe Mode Fiasco
Apr 5, 2010i just got the 2.1 update this morning and was cleaning up a few unused apps and i came across launcher. I couldn't believe I still had it on here (been using sweeterhome) and so i remembered i had to go into safe mode to remove it. Tried to get into safe mode no luck. thought, ok, i'm missing a step or something. looked up the directions to make sure i was doing each step correctly and still nothing! i've held the power button and the menu button (keyboard) down at the same time until i saw the eye, until after the haptic then major vibration. i tried holding the menu and power, then releasing the power while still holding menu until both things i just stated and still nothing! what is happening is after I hold the buttons until after the vibration one of two things happens,it will go back to the screen that spells out droid then the eye or it will load normally, no safe mode on the screen. i read somewhere doing a google search that someone else had this same experience and asked for help and no one replied.
