I'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?

What is the best way to launch an app and calculate its launch time in android(if it can be done with some code,then its better)
View 2 Replies View RelatedMy app is comprised of a set of reusable Activities that other apps can reuse. For various reasons, I would like my Activities to be launched in context of the invoking Activity's process, instead of always being launched in my Activity's process (default behavior on Android). How can I achieve this?

View 1 Replies View RelatedIs 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);
}
}

View 3 Replies View RelatedI have an screen that displays all the names in the Contacts in a ListView. When the user clicks on a name, I want to launch another Activity which display the details of the selected Contact (Phone number/ email) in another screen. How do I display details for the selected row. (i.e When starting the intent how do I send over the row_id of the item selected)?
I've tried the following code:
Intent i = new Intent(this, ContactDetails.class);
startActivity(i);
In 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.
I'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?

I 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:...............

The program launches no problem when i just implement the first button (restuarant).
But when i try to implement the button that i have commented out it fails to launch. and yes i have added the activity to the manifest file.
i'd like to Launch an Activity Form a Service. I know that this is not best practice for android however i am creating an application that is just a service and the first time it runs the user needs to accept some terms and conditions (this is the activity i need to launch). Can any one help me some code to do this? Is it possible?

View 5 Replies View RelatedAre 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.

View 1 Replies View RelatedI am trying to create a small pop-up in my Android application to let the user choose from one of many items, ala a ListView. I am hoping to make it show up as a translucent box that overlays on the screen, as opposed to completely occupying it like Activities usually do. One technique for doing this that I've heard is possible is to launch an Activity in an AlertDialog box. This would be perfect - it's the ideal size and has a lot of the mechanical properties I'm looking for, but I'm totally unable to find any more specifics of this technique. Is this possible? And if not, what is the preferred way of accomplishing something like this?
