One of my application need to know a new day is coming, that is, if the clock of phone changed from 23:59 to 00:00, my application will do some logic. I tried to use android.intent.action.DATE_CHANGED, but based on my test, this event only occured when i change the date mannually, I could not get this action when clock changed from 23:59 to 00:00.

im currently looking for the way that my app knows when the phone has being paired and connected to a bluetooth headset device.
I read something about this intent, but not on the Reference documentation of http://developer.android.com
android.bluetooth.a2dp.intent.action.SINK_STATE_CHANGED
Is this actually working, is it officially supported.
I mean, can we just register a broadcastreceiver to handle this intent , check for the EXTRA_STATE string extra to see if it equals STATE_CONNECTED and be sure that the phone is now connected with a bluetooth headset device ?
What about this BluetoothA2dpService class? There is no official documentation about this, everything i found i from code snippets of the android OS source code.
I couldnt figure out the exact understanding of implicit intents.
When i was going through the tutorial i read about it.
Here are some important points to remember: 1 - Implicit Intents do not specify a target component 2 - Components willing to receive implicit intents have to declare their ability to handle a specific intent by declaring intent filters 3 - A component can declare any number of Intent Filters 4 - There can be more than one component that declares the same Intent Filters and hence can respond to the same implicit intent. In that case the user is presented both the component options and he can choose which one he wants to continue with 5- You can set priorities for the intent filters to ensure the order of responses.
I read this about Implicit Intents.
I couldnt get visualisation of 4th point. So wanted to try it out by writing some examples.
I tested this like below. Wrote two apps.
I had written two activities in one app, CallingActivity & anotherActivity.
CODE:...........
One more app,which has two activities like below.
CODE:..................
I ran the first app in emulator and pressed home screen, it mean it runs in the background.(Not exited ) Then i opened the second app and clicked a button in frirst activity(testmain) and tried to call setAction "com.android.localguide.GET_RESULT"
i.setAction("com.android.localguide.GET_RESULT");
But it is opening the activity "results".. It dint showed a options to choose which components( i expected first app ) activity i need to use ?
Am i right in executing in the right context to understand that point no 4 ?
I want to show some notification when android phone is connected to system. I implemented BroadcastReceiver for listening to event android.intent.action.ACTION_UMS_CONNECTED in my application But it is not working. Is it possible to capture this event.
View 3 Replies View Relatedi have code that runs onitemselectedlistener event of spinner.So when i am in the method :
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
//I want to do something here if its a user who changed the the selected item
}
... can i know whether item selection was changed programmatically or by a user action through UI.
Do any have idea about how do I get notification when the day changes from 23:59:50 to 00. There in intent broad casted as DATE_CHANGED by android but this intent is to get notified only if the date is changed by user it seems. I have basically have my function to run on the event.

How to invoke call in android using ntent?...
View 2 Replies View RelatedI'm trying to get an application / reciever / anything that can perform a task once every minute. I'm trying to use the intent-filter "android.intent.action.TIME_TICK" which, in theory, sends an Intent message every minute.
Does anyone have any code that uses the android.intent.action.TIME_TICK intent? I can't seem to get it to send the intent to my application and I can't find anything much on the internet. Has anyone used it successfully?
I have a manifest.xml as below.

When creating an intent with action send to send some data, is there a way to filter the results that are included in the activity chooser that is created using Intent.createChooser? I have not seen a way to do this other than setting the mime type, but it is not flexible enough.
For example, there is a situation when I want e-mail apps to be the only results in the activity chooser dialog. Setting the type to "text/ html" successfully filters this down to email apps, except when bluetooth is enabled. Bluetooth appears in the list as well, but this is not desirable. Surely there is a way to have a little more control over the results?
How to cath android.intent.action.MEDIA_MOUNTED event I implemented an broadcast receiver to invoke when sdcard is mounted. But it is not invoked
My source code is as follows:
CODE:..................
I've got a receiver set up in my android application to catch android.intent.action.NOTIFICATION_REMOVE intents. On my Evo, it works fine - when a notification is cleared from the notification bar, I catch that event and can run some code. I tried running this on a Samsung Moment though, and it is never caught. So now I'm trying to figure out why, and I can't seem to find anything on Google about this intent action - and I set this code up a few months ago, so I don't remember where I even found this action, it doesn't seem to be in the API.
The evo is running 2.2, and the moment is running 2.1-update1, so I'm guessing that it's undocumented, and only available in 2.2. Is there any other way to catch an event that a notification has been cleared? Note that I'm not trying to cancel a notification that I put up, or trying to cancel another app's notification, just catch an event when a notification has been cleared.
Here's my receiver in AndroidManafest.xml:

I want to receive Intent "android.intent.action.SEND" in a Service. Is it possilbe to register for this Intent via registerReceiver() and get the Intent in Broadcast receiver in the Service?
Or is there any restrictions that "android.intent.action.SEND" can only be registered via Manifest.xml of an Activity and not in a Service?
what is intent action name(e.g. action name "android.media.action.IMAGE_CAPTURE" for launching camera appl) to launch the native map appl Is there intent available(documented or undocumented since above intent of capturing image is undocumented ) for launching maps appl?
I know one for launching maps for driving direction "this.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://maps.google.com/maps? f=d&saddr=37.4,-121.9"+ "&daddr=Bellevue, WA&hl=en")));" but this goes to driving direction page of maps appl.
is there any way to launch maps appl which will open maps home page?
I'm trying to catch an action like ACTION_HEADSET_PLUG. But I think it might be too much to set this action on the manifest file.
How could I register a listener for this action? I only need to care about it when my application is running not all the time as I think it would happen when registering it under the manifest file...
I'm making an app that needs to sort a Sqlite table of weeks by date and display just the date and the total hours worked that week in a listview. My activity extends listview and uses SimpleCursorAdapter to populate the listview. My date column is a TEXT field formatted like this "YYYY-MM-DD" Here is my database query function, I base my database helper class off of the google notepad example.
public Cursor getAllWeeks()
{
Cursor mCursor = mDb.query(true, DATABASE_TABLE, null, null, null, null, null, "weekdate ASC", null);
if (mCursor != null)
{
mCursor.moveToFirst();
}
return mCursor;

I am trying to take picture by G1 camera.
I have tried almost everything i was able to find on the net about this topic. It seams there should be intent with action "android.media.action.IMAGE_CAPTURE" which really starts camera application and returns captured image. But captured image is scaled to 0.25 of original size. Another possibility I have found is to pass uri where to save captured image. I went through all available sources of camera application and it should work but does not.
For illustration, I am doing following in my example activity which creates new image, but after returning from camera, image is still empty:
CODE:..................
I am ready to write my own capturing application, but it is quite hard and I would like to reuse.
Do you know correct intent action name and extra name to pass to capture image?
I am trying to launch an activity by specifying only its action(custom) defined in its intent filter from an activity in other application. The activity to be launched is the main activity of its application thus have android.intent.action.MAIN & android.intent.category.LAUNCHER set as action and category in its intent filter. Now according to android doc on Intent and Intent Filter, i do not need to specify DEFAULT category at all in this case. But doing the same i am i am unable to launch the activity.
LogCat says, Activity could not be found...
Am i misinterpreting the text or is there something else missing...?

Definition of Activity being called in the manifest file

Can any one suggest some helpful links so that I can get free online tutorial?
View 1 Replies View RelatedI got one question regarding the intent action "ACTION_CALL". What is the correct way of getting back to the own application/activity after the user ends the call? The only way that came to my mind uses a PhoneStateListener in a background services that waits for the CALL_STATE_IDLE event starting up the application again. But I am not quite sure if that is the correct/intended way of using the intent.

View 3 Replies View RelatedI am customizing native phonebook application as a third party application which can be launched by the same intent as the native application. I have installed that application in my G1 phone. When I have clicked on Contacts icon in launcher menu it a menu pops out and asks me to select which app to lauch i.e., native contacts or my customized contact application. I have selected my application and I have also selected to use this selection as my default choice. After that system never put a pop-up and whenever I clicked on contacts it launches my customized application.
Now my problem is, I do not know how do I change this setting i.e., tell the phone to put the pop-up again so that I can select native app or my app?
Does anyone has any idea?

But when the Emulator runned .Then, a dialog occur with message : "TestCall has stopped".TestCall is my project..I also want to get a table of ACTION and DATA of Intent.
To understand the implicit intents by example.
View 2 Replies View RelatedI've tried Unified Remote and WinApp off the market, both highly rated, both practically useless for me, if for example you run a setup program the input just stops working so you have to plug a mouse in to complete which completely renders the app pointless to me. That was just an example, all of the ones I've tried have been so flakey as to be frustrating.
Are there any apps that can act as keyboard and mouse for a remote windows system that actually work 100% of the time?
I think everyone who upgraded should test this out right away. I was taking pictures last night with my flash, and I noticed that even though the LED comes on, it turns off again the instant before the shutter closes. This problem is reproducible 100% of the time, and happens whether the picture is taken with the shutter button or the new touch button. This has basically rendered the flash useless.

I am adding to Android Manifest file as I want it active through my application life time. But the problem is that I am not getting the broad cast event from the system when battery status changes.
My code is here :-

<intent-filter>
<action android:name="android.intent.action.BATTERY_CHANGED" />

I'd like to show a png or jpg I downloaded from the next in an image viewer intent, but can't get it to work.
Bitmap bmp = getImageBitmap(jpg);
String path = getFilesDir().getAbsolutePath() + "/test.png";
File file = new File(path);
FileOutputStream fos = new FileOutputStream(file);
bmp.compress( CompressFormat.PNG, 100, fos );
fos.close();
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(path)), "image/png");
startActivity(intent);
I know the bitmap is downloaded ok (use the same routine for supplying it my ImageView instances elsewhere in my app) - I think it wrote to file ok, I can see it on disk and the file size is correct. The intent is launched but an exception is thrown: then the new activity just sits there, blank. How does this work?
