Android : Is It Safe To Launch / Activity From A Non-ui Thread?
Jul 21, 2010Suppose my activity ui-thread spawns a separate thread at some point. Is it safe for that new thread to fire off an Intent for launching a new activity?

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?
Android :: 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?
HTC Incredible :: Thread Dedicated To The Safe Removal Of Apps

View 1 Replies View RelatedAndroid :: Launch Activity Without UI?
Apr 24, 2010Is it in any way possible to launch an activity from the main function without having a UI? i.e. is there a way to create a sort of "wrapper" around another activity, i.e. by launching the main activity, it takes you to another activity automatically. If that is not possible, is there a way to remove the main activity from the stack so that clicking the back button does not take you to a blank UI?
Here's an example of what I'm trying to do:
public class WrapperActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse("tel:555-1212"));
startActivity(intent);
}
}

Dec 28, 2009I'm new to Android development, so I might be missing something obvious. I want to launch an activity when the user's phone clock hits a specified time (similar to an alarm). However, I'm not sure how I would go about doing this as constant polling of the clock seems inefficient and a waste of resources. Do I need to capture broadcast events from the lclock, or use PendingIntents?

Android :: Launch An Activity In A New Process
Jul 29, 2010In order to keep some native code happy, I need to launch an activity in a new process. Does anyone know how to do this?
I can set the activity's process attribute in the manifest, but this will cause *all* instances of the activity to appear in the *same* process, which I can't have.
I'm willing to use internal APIs for this, and I've found Process.start(), but it's not at all clear how this is supposed to be used.
Android :: How To Update App's Icon Launch Activity?
Jul 14, 2010I'm currently running into an issue that makes sense but I'm not too sure how to resolve it... Here is the scenario: App v1 icon LAUNCH is set to Activity Main from the manifest file. App v2 icon LAUNCH is set to Activity All from the manifest file and Activity Main no longer exists. After updating to App v2 the app icon fails to launch the application saying it doesn't exist! After a restart of the phone things work. So how can I refresh the applications package or better the launch icon and shortcut icons so that my users don't experience this after an upgrade of my newest app version?

Android :: RatingBar OnClick To Launch New Activity
Aug 9, 2010I have a ListView that uses different XML files to create Views and make items out of. One of these XML files contains a RatingBar. Everything displays and looks excellent. I'm trying to attach an onClick handler to the RatingBar to launch a new Activity. My RatingBar is of style ?android:attr/ratingBarStyleSmall; so it's just an indicator (I want the small RatingBar click to take the user to an Activity where they can do various ratings).
My problem is the onClick handler for the RatingBar never gets executed. What makes it more interesting is that I've used the same code to make a LinearLayout clickable and it works fine. My Adapter's getView looks as such:...............

View 5 Replies View RelatedAndroid : Can App's Main Activity Be Bypassed On Launch?
May 9, 2010Are there any scenarios on Android where a process can be instantiated (classes loaded, etc.) and a non-main activity launched without going through the main activity? Background: my app has a single main activity (android:name="android.intent.action.MAIN" and android:name="android.intent.category.LAUNCHER"), some secondary activities, and a preferences class providing static methods meant to be called from anywhere. These static methods' implementations require a Context, and so the class has a static Context member s_context; the static methods assert that s_context is non-null before using it. The very first thing I do in my main activity's onCreate() method is pass getApplicationContext() into the preferences class so it can set s_context.
