I'm looking for a way to resume my activity (which makes phone call) after call ends by user. Currently after user ends a call, it always returns to the phone's native call-log screen instead of the activity that originated the call. Is there any way to prevent or customize this?

I have an application with contains multiple activities. The main activity will start the others ( use startActivity() ) depends on user event, when an activity close, it calls finish() and return back to main activity. It appears to behavior like that.
However, the "problem" I see is main activity's onCreate function is called every time. I think the the main activity should be placed in the activity stack and simply push to front when others exit, therefore only onResume, onStart are called. Is there some flag I need to set or I misunderstand the activity behaviro?
In child activity, besides calling finish() or startActivity for main activity, what is other way to move main activity to front?

BUTTON_POSITIVE) ;finish();

I have called the startActivity(intent) and the new activity loads. How do I go 'back' to the calling activity once a button is pushed. 'Popping' the activity off the stack basically.
I am currently calling the dialer from within my activity using the following code

So i rooted with Droid Does rom, because i heard its nice and fast and what not. So basically the only problem i have with it is this.
When on a call, the proximity sensor doesnt work, so the screen goes black. And when i press the end call button to turn the screen back on it just ends the call. Is this normal? Or a known issue?
I have an already built application and I want to add a feature that has to be started when a call ends.
How can I achieve that?

Could be enough, but what kind of intent I have to put on the filter?
Looking in the documentation I found only the intents that detects when a call is started.
I've read around that with Froyo you can go into Settings> Accessibility and turn on a feature called Power button ends call. Fairly obvious what it does, but i can't find it. Is it not available on the desire. If so, is there an app for that, or some other way to do it?

What I want for the second situation is for the app to start A instead of B. How can that be done?

View 2 Replies View RelatedI have 3 classes in my example:
Class A, the main activity. Class A calls a startActivityForResult:
Intent intent = new Intent(this, ClassB.class);
startActivityForResult(intent, "STRING");
Class B, this class is a TabActivity:
Intent intent = new Intent(this, ClassC.class);
tabHost.addTab...
Class C, this class is a regular Activity:
Intent intent = this.getIntent();
intent.putExtra("SOMETHING", "EXTRAS");
this.setResult(RESULT_OK, intent);
finish();
onActivityResult is called in Class A, but the resultCode is RESULT_CANCELED instead of RESULT_OK and the returned intent is null. How do I return something from the Activity inside a TabHost?
I realize that the problem is that my Class C is actually running inside of Class B, and Class B is what is returning the RESULT_CANCELED back to Class A. I just don't know a work around yet.
I'm really new in Android programming, so I have a simple question getting a phone number from contacts in my application. The method I want to implement is that the user clicks a button in my app and will be forwarded to the contacts. In contacts user has to click on a phone number and this number should be returned to a textfield. Is there a simple way to do this instead to implement it by ContentResolver?
View 1 Replies View RelatedMy MAIN activity is spawning a child activity that contains a ListView. While this ListView is being populated (through an AsyncTask), an indeterminate progress bar is shown.However, assuming that I am an impatient user and I press the BACK button, the progress bar is cancelled but I am left with a blank screen. I have to press BACK one more time to go back to the MAIN activity.I would like the app to go back directly to the MAIN activity by pressing BACK only once. Can somebody point me in the right direction? I am thinking I should call finish() somewhere but I don't know where to put it.

I have an android application with a LOT of activities, think of something like a book where every page is a new activity. The user can make changes in each activity, for example highlight certain texts with different colored markers etc. and it's crucial that I'll remember this information as long as the application stays alive (and I don't want/need to remember any of this when it's not). As I understand the best mechanism for storing this kind of information is via onSaveInstanceState(Bundle outState) and onCreate(Bundle)/onRestoreInstanceState(Bundle) rather than lets say, the Preferences mechanism. My only problem is that the user can navigate backwards to previous pages (Activities) and the only way i know of achieving this is by calling finish() which of course kills the current activity without calling onSaveInstanceState(Bundle outState) and even if it did call it, the next time I would launch an activity representing that page it would be an entirely new instance. So my question is: Is there a way to go back to the previous activity without calling finish()? or, is there a better way to save this information? maybe through static variables?

View 3 Replies View RelatedI'm trying to figure out the correct way to create an AsyncTask to retrieve some data from the internet and then to take that data and bundle it up in an Intent and pass it to a new activity(A list display). So in the first activity I just have an EditText and Button. In the event of an OnClick the task should be called and when it is finished the data should be bundled inside an Intent and passed to the next Activity. The problem is when I take the results from onPostExecute and set them to an instance variable of the main activity, that instance variable is still null when the task is complete. Here is the barebones version of the code:
CODE:...........
When I debug the application I see onPostExecute does contain a valid PlacesList full of results, so why is the instance variable places set to null after the task is executed? I am going about "returning data" from an AsyncTask incorrectly?
