Android : Call App Activities From Stand-alone Widget?
Dec 29, 2009
I currently have widget for my app Hire*A*Droid bundled with the main application. I would like to unbundle the widget and release it as a separate offering. However - the widget is relying on Activities from the main app so I need to navigate between these two mainly calling particular Activity of the main app from the widget. So the basic idea - app can work without widget and the widget becomes the "add-on" option.
What is the "right" way to call app activities from the stand-alone widget? Do I convert the main app into a content provider? Can you point me to any code samples perhaps?
P.S. I'm not asking how to call Activities from the widget that is bundled in the same APK. The question specifically states that widget is distributed separately from the app it's calling

My Droid was in its leather carrying case in my backpack for about an hour while I was at the gym. When I pulled it out it was hot. Not warm, but hot. I couldn't stand to hold it against my ear to make a call.
When I pulled up the battery usage it did not appear to be anything out of the ordinary. The keyboard was locked when I pulled it out of the case so that eliminates errant keypresses opening up a bunch of apps and making calls while it was in there.

Say I have 2 activities (ActivityOne and ActivityTwo). How would I call ActivityTwo from ActivityOne? Then how would I return to ActivityOne from ActivityTwo? For example, I have a listview with all the contacts on the host phone. When I tap on a contact, another activity shows information and allows editing of that contact. Then I could hit the back button, and I would go back to the exact state that ActivityOne was in before I called ActivityTwo. I was thinking an Intent object, but I am not sure. Could someone post some code?

Is it possible with one call to finish all previous Activities. (like: this.finish(all) :)
I have a main activity, calling a preferences and there is a switchuser point that switch the user and call the main activity again. But than i don't need that the user can go back, step by step, It would be just fine i could say "kill all previous activities" in the moment the user click "switch user".

Is there a way to have a calendar widget on the home screen with the days current activities? I saw it on one of the scene layouts.. I think it was the work one but I want to use the sprint scene and add that widget. Is this possible? Also, is there a to do list or task list app built in or do I need to download one. If I do have to download one are there any recommendations.

I've read through the Application Fundamentals three times today (and I had done so before), but I still can't quite wrap my ahead around the task concept. Or I guess I thought I understood it, but usually, the results I am seeing don't match up to what I would expect to happen (maybe a tool to see the current tasks/activities etc. for debugging purposes would be a nice addition).
I have multiple widgets from my provider in the Launcher desktop, and each is using a PendingIntent with a different URI as data (so they should be separate intents) to open an Activity.
I want there to be only once concurrent instance of this Activity that the user can access. So clicking the widget (1) , pressing HOME (2), clicking a different widget (3), pressing BACK (4) should bring the user back to the Desktop.
Now I did manage to do this using launchMode="singleTask" - the existing instance is brought to the top, onNewIntent() is called and I am pretty satisfied with it.
However, supposedly there are other ways to achieve an equivalent effect (say with having the activity restarted), and I'd like to understand why I don't seem to be able to get them to work: In every case, instead of seeing the home screen after step (4) (after pressing BACK), I see the *previous* instance of the Activity.
For example, if I read this correctly:
"There's another way to force activities to be removed from the stack. If an Intent object includes the FLAG_ACTIVITY_CLEAR_TOP flag, and the target task already has an instance of the type of activity that should handle the intent in its stack, all activities above that instance are cleared away so that it stands at the top of the stack and can respond to the intent. If the launch mode of the designated activity is "standard", it too will be removed from the stack, and a new instance will be launched to handle the incoming intent." http://developer.android.com/guide/topics/fundamentals.html
Then simply using using the following code to start my Activity from my widget should do what I want, no?
CODE:............
So in (3) My activity should be launched using FLAG_ACTIVITY_NEW_TASK by the launcher, which due to process affinity would find the existing task (which would consist of a single instance of my Activity), and launch the new instance on top of it. This explains what I am seeing. Why doesn't FLAG_ACTIVITY_CLEAR_TOP cause the existing instance in the task to be replaced?
Even setting android:launchMode explicitely to "standard", as mentioned in the doc quote above, this doesn't seem to change things.
I also tried android:finishOnTaskLaunch="true", but the behaviour is the exact same was just described with FLAG_ACTIVITY_CLEAR_TOP (which seems to be the exact same as when doing neither and really starting an activity without any special attributes).
I should mention that If I click the same widget in (3) as I clicked in (1), i.e. using the same PendingIntent twice, I do get the previous instance brought to the front (not restarted), but again, regardless of whether FLAG_ACTIVITY_CLEAR_TOP or finishOnTaskLaunch are being used.
I find this especially strange since the docs about tasks don't seem to mention the intent itself being relevant at all. Application Fundamentals does at one point say "For the default "standard" mode, a new instance is created to respond to every new intent", but it's not clear what "new intent" means then. Is triggering a PendingIntent multiple times through a widget not multiple "new" intents then?
I also tried various combinations of the other related options, but pretty much got nowhere.

I saw many sample codes that each variable contains the 'm' prefix. I don't know what this m means. I have two-year experience in MFC. Each variable has 'm' prefix to tell you that I'm the one variable of MFC component. (m stands for MFC). can anybody answer me this question?

i'm looking for a stand alone contact manager app that will allow me to import contacts and map custom fields from our CRM database. depending on the user, their database can be anywhere from a few hundred to a few thousand contacts. in an effort to keep things clean (business vs. personal), i'd like to keep these out of the built in contact manager.

I wrote a widget that can call numbers directly with one click. It works on the emulator, and it used to work on my nexus one when it had Android 2.1. Now I got the update, and the widget stopped working. I am using Intent.ACTION_CALL, and android.permission.CALL_PHONE. If I change to Intent.ACTION_DIAL it works, and the same code works from an activity. It is the combination of an app widget and the call action. I don't see any error. Does anyone know if it is not possible, and if so, how? Are there many cases the emulator is different than the cell phones, concerning the permission aspects?
The numbers are all regular, not 911 or something.

Can anyone recommend a widget that shows the number of missed calls / text messages / emails? I would prefer something that is text only.If not, does anyone know a widget that can display text from a file on the SD card? I could probably figure out how to use Tasker to generate the text file if needed.

I have downloaded the full Android source code & pulled out the contact source into a different folder. I am trying to create a separate Contacts "stand alone" App using the existing android contacts source code, once that done I intend to add some more features (code) to contacts source & make a contacts.apk out of it. Is it possible? The problem I faced was, when I pulled the contacts app source code, there were many internal api calls & Private api references. I tried to resolve them by including those internal api source code & class files (available from the android source code) in my project, but there are still many errors & internal api calls, which I am not sure how to resolve them like:
import android.os.ServiceManager android.provider.Gmail android.provider.Im android.provider.Telephony acquireProvider(Uri) deleteRow() lookupProviderNameFromId(int) ISyncAdapter IContentProvider etc.
Is there a way to solve these internal API issue? Was there anyone who has successfully extended any of the existing apps (Contacts, Alaram, calendar.) of android with the help of its source code, is this approach possible? I tried to include the "framework_immediates classes.jar" in the project, but due to duplicate class files present in the project & SDK it throws the ususal - UNEXPECTED TOP-LEVEL EXCEPTION: class file already added com/android/ internal/telephony/callerInfosync. I have been trying to achieve this for the past 2 days, with not much success. Can somebody lead me to a correct direction?

Okay so I've tried a few different Calendar apps, and they all seem to link to either Google, or the stock Calendar. Is there an app out there that has all the functions of one of these, reoccurring events, Colored event bars etc, BUT does not link to either the stock or Google, or any other type. I'm not happy with the way this linking system works, but I DO need a calendar with event tabs for my work rota, holidays, pay days etc.

I know I've asked a lot of questions about getting the stock Android apps and keyboards, etc. But I am very concerned as it may mean taking back my Eris.
For some reason, I just cannot stand the HTC apps. For example, the Messaging app, the black notification bar and different battery icon, the Mail app, etc. They just look cheap or something. I don't use Sense UI, I have it set to Default Home. I don't really like HTC's keyboard as much as the stock Android one either. I bought the Eris because of the price, and how much lighter and thinner it is and how much better it looks than the Motorola Droid. However, I would really love to know if we can get the stock Android look and feel, for example the stock Android keyboard, stock notification bar color, stock messaging app, after the 2.0/2.1 update or after it is rooted. It just looks so much more dark and rich. I don't like white color schemes like in the HTC messaging app. (And don't say use Handcent because I don't like it either and I don't want to replace any apps.) Is it possible to just install the stock Android OS after it is rooted?

I know about camel case rules, but I'm confused with this m rule. What does it stand for? I'm a php developer, "we" use first letters of variables as indication of type, like 'b' for boolean, 'i' for integer and so on.
Is 'm' a java thing? Does it stand for mobile? mixed?
