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.
I added broadcast listener "BATTERY_CHANGED" to Android Manifest file so that when the status changed I should get informed. 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 :- <receiver android:name=".MyBroadcastReceiver" android:enabled="true" android:permission="android.permission.BROADCAST_STICKY"> <intent-filter> <action android:name="android.intent.action.BATTERY_CHANGED" /> </intent-filter> </receiver> <uses-permission android:name="android.permission.BATTERY_STATS"/> <uses-permission android:name="android.permission.BROADCAST_STICKY"/>
Code... Doing something like this, but can't get notification.Reference said :
public static final String ACTION_PACKAGE_REMOVED
Since: API Level 1 Broadcast Action: An existing application package has been removed from the device. The data contains the name of the package. The package that is being installed does not receive this Intent
A need this intent to set uninstall password. Any suggestions?
I thought that Action was preeminent during intent resolution and if the intent had the same action as the intent filter, it would be considered a match regardless of data, if the filter did not specify anything. So I was very surprised to find that supplying action+data where filter had only action, causes it to fail. In the code below, if you comment out line 47 so that data is *not* sent, only then it resolves correctly. To get it to work with the data (an id that is simply a String), what mime type should I specify in the intent filter?
I'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?
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?
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.
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 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:
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...?
Code, used for calling the activity
Definition of Activity being called in the manifest file
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.
One more app,which has two activities like below.
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"
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 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.
I have a Service defined in the manifest with an intent filter that refuses to match when specified as a String resource but works when the literal action is entered in the manifest. Is there any reason I should not be able to use a String resource with an action in an intent filter?
I 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?
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.
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.
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?
yesterday, I spent several hours trying to figure out how to capture the HEADSET_PLUG intent with a BroadcastReceiver. The manifest defines the <receiver>, with its intent-filter set to <action android:name="android.intent.action.HEADSET_PLUG" />.
The receiver is working correctly (I verified that by changing the intent filter to capture things like SMS_RECEIVED including the proper permissions and the receiver fired as expected on receiving an SMS), but when listening for HEADSET_PLUG, it never fires. Debugging the whole thing is a bit complicated, as the emulator doesn't seem to support headsets and I have to disconnect my target device (a HTC Dream) from USB in order to attach a headset (so there's no logfile viewing). Are there any special permissions required for applications to capture the HEADSET_PLUG intent (and if so, which? I've tried several, to no avail)?
Maybe the Dream doesn't fire such an intent at all (that'd be bad luck for me), but I guess that it must be an issue related to application permissions. The documentation says extremely little (well, actually: nothing) about the single permissions needed to perform all the actions described in the API docs, so this is absolutely something to be improved.
What I want to do: Upon detecting a headset, I want to re-route the ringtones from the speakers to the headset, so as not to annoy people in my vicinity by a harsh ringing sound (I'm used to this behaviour from my old phone) - by default, the speaker just keeps on ringing, no matter whether a headset is attached or not. This part is already working, but now I need to know how to detect headset attachment/ detachment events.
I am working on creating an Action Bar like the one from the new Android UI Patterns and I am running into a bit of trouble. I have a ViewSwitcher with two layouts in it. When the user taps the search button I animate between the two layouts. The problem is that the layouts are different sizes and I can't figure out how to make them take up the same amount of space. Here's what I mean. p.s. forgive the bad art, they are just place holders ;)
I was wondering if its possible to have a broadcast receiver to listen when the app its in launches.I tried doing by creating a BroadcastReceiver to listen for the android.intent.action.MAIN action but it never gets called?Is there something I need to do or a different action I should be listening for?
