I did the test with "HelloAndroid" app, but I have no clue on how to run the app on my phone via Eclipse. I remember reading about it a long time ago (sometime in February) but I have no idea where to find it.

I'm having a problem with emulator-5554, it keeps telling me it is offline. When I do a 'adb devices' from the command line it says
emulator-5554 offline
Even after a fresh restart, I try that command and it still says it is offline. The problem is when I try to install .apk files to the emulator using 'abd install path' from the command prompt, it tells me that it is offline, if I create another device and run that one, then try to install the .apk files, it says i have too many devices connected. So in other words, I can't install my .apk files. How in the world can I get rid of that damn emulator-5554? I heard that if you do a restart, it should clear all the devices, but that does not seem to be working. It is like it is getting initialized when my computer starts up.
My 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'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?
View 1 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?

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:...............
