Android : Can't Get Intent Filter To Launch Activity From A Uri
Aug 14, 2010
I'm trying to figure out how to launch an activity in my app from a custom URI such as myapp://myuriactivity I've read a lot about the intent and intent filters in the android references and also read several examples, but for some reason I can't get my simple test to work. Below is my manifest file, can anyone tell me what I'm doing wrong? With the below file, if I open the browser and try to navigate to http://org.test.launchtest it just says the page doesn't exist. Shouldn't this work?

I'm registering an intent-filter on an activity to listen for url clicks from a certain domain:
CODE:.............
This works, but is there a way to filter out certain urls from my domain? For example, my app can only do something useful for the user if it gets a url like: www.mywebsite.com/orange
But if the user clicks on a link like: www.mywebsite.com/blue
I can't do anything useful for them, so I'd like to just let them continue using the browser to open that url. Is there a way I get a chance to see the URL before android pops up the chooser dialog and presents my app as a possible handler for the url? Is there some method in Activity which allows me to filter?

I'm using an intent-filter on URLs for my activity:
CODE:...............
the launchMode attribute is set to "singleTop", but it looks like a new activity is created every time I click a matching url. I thought that if the activity is already alive somewhere, it would simply be brought to the front of my activity stack?
I tried this on the emulator/device, same behavior, a new activity instance is always created.

I'm having difficulties handling multiple instances of my root (main) activity for my application. My app in question has an intent filter in place to launch my application when opening an email attatchment from the "Email" app. My problem is if I launch my application first through the the android applications screen and then launch my application via opening the Email attachment it creates two instances of my root activity. steps: Launch root activity A, press home Open email attachment, intent filter triggers launches root activity A Is it possible when opening the Email attachment that when the OS tries to launch my application it detects there is already an instance of it running and use that or remove/clear that instance?

The first activity in my app needs to load a small amount of data from a text file. Two strings and an integer. Once I load the data, I want to use one of the strings to create an intent, that will launch the next activity.

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
CODE:.............
Definition of Activity being called in the manifest file
COE:....................

I want to specifically run the default Android browser for a given URL. I'm using this code: I also tried adding <uses-library android:name="com.google.android.browser" /> to the manifest. Am I missing something here? PS: I'm not interested in using startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com"))) as it will list all the choices for the browsing Intent.

Perhaps I'm misunderstanding how Intents and intent-filters work, but it seems to me that this should be a strait-forward case. However it's not working. Here is the Intent I'm sending:
Intent i = new Intent(Intent.ACTION_VIEW);
i.setType("vnd.android.cursor.item/vnd.connectsy.event");
startActivity(i);
And here is the intent-filter:
<activity android:name=".events.EventView">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<data android:mimeType="vnd.android.cursor.item/vnd.connectsy.event" />
</intent-filter>
</activity>
And finally, the error I'm receiving:
android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW typ=vnd.android.cursor.item/vnd.connectsy.event }

I built an Android application that requires OAuth. All was working well using a custom scheme call back which is intercepted by Android. It seems that Yahoo have changed the goal posts and now the custom scheme is not accepted by Yahoo.I am now looking at possible alternate approaches. My first attempt is to use a normal http scheme and modify my intent filter to intercept the new URL. I have the following in my AndroidManifest.xml :
<intent-filter>
<action android:name="android.intent.action.VIEW"></action>
<category android:name="android.intent.category.DEFAULT"></category>
<category android:name="android.intent.category.BROWSABLE"></category>
<data android:host="www.test.com" android:scheme="http"></data>
</intent-filter>
Where www.test.com will be substituted with a domain that I own. It seems :
* This filter is triggered when I click on a link on a page.
* It is not triggered on the redirect by Yahoo, the browser opens the website at www.test.com
* It is not triggered when I enter the domain name directly in the browser.
So can anybody help me with
* When exactly this intent-filter will be triggered?
* Any changes to the intent-filter or permissions that will widen the filter to apply to redirect requests?
* Any other approaches I could use?

I have looked at the intent-filter documentation and I can't figure out this specific intent-filter. I'm looking to use ACTION_SEND because I only want the app to show up in "Share" menus in other apps. I only want to show up in the share menu if the text of the intent is a url. For example, what is shared from the Android Browser's share menu. I don't want the app to appear in the share menu if it's just text and not a url.

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 realise one has to use an intent filter to associate a file format with an application, but once this is done how does the app 'receive' the path to the file that was chosen? Is there a special method it calls on the Activity?

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...

Trying to grok intents and actions in android and looking through the documentation. But one thing I keep seeing is an intent filter with multiple actions defined.
Like this, from the above link:
CODE:...........
But, if you call that activity, how does it choose which action is chosen?
For that matter, that linked to example has multiple activities that all contain the same actions, "android.intent.action.VIEW" for example. When calling this with something like content://com.google.provider.NotePad/notes how does it even know which activity to use?

I'm trying to get a BroadcastReceiver invoked when the screen is turned on. In my AndroidManifest.xml I have specified:
<receiver android:name="IntentReceiver">
<intent-filter>
<action android:name="android.intent.action.SCREEN_ON">
</action>
</intent-filter>
</receiver>
However it seems the receiver is never invoked (breakpoints don't fire, log statements ignored). I've swapped out SCREEN_ON for BOOT_COMPLETED for a test, and this does get invoked. This is in a 1.6 (SDK level 4) project. A Google Code Search revealed this, I downloaded the project and synced it, converted it to work with latest tools, but it too is not able to intercept that event.
http://www.google.com/codesearch/p?hl=en#_8L9bayv7qE/trunk/phxandroid-intent-query/AndroidManifest.xml&q=android.intent.action.SCREEN_ON
Is this perhaps no longer supported? Previously I have been able to intercept this event successfully with a call to Context.registerReceiver() like so:
registerReceiver(new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
// ... }
}, new IntentFilter(Intent.ACTION_SCREEN_ON));
However this was performed by a long-living Service. Following sage advice from CommonsWare I have elected to try to remove the long-living Service and use different techniques. But I still need to detect the screen off and on events.

I want to set up a BroadcastReceiver to handle PACKAGE_REPLACED, but I only want to be notified when my package is replaced. It works fine if I specify a data tag with scheme="package" but then I get notified when any application is reinstalled or upgraded. I can't figure out how I'm supposed to specify the package name which is in the scheme specific part -- that is, when my BroadcastReceiver gets the intent in onRecieve(), if I do intent.getData().getSchemeSpecificPart(), that's the package name, but is there any way I can filter for only that in my intent-filter?

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?

This question has been asked [numerous times] before, but I have not seen any definitive answers, or examples of code that actually works. I would like to associate an Activity with a particular file type. For discussion, assume that I want my Activity to be associated with PDFs. Here is what I currently have. I have experimented with many different values and combinations of values in the intent-filter, but I have yet to get my Activity to start when a PDF is selected.
<activity name="com.mycompany.MyActivity">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="file" />
<data android:mimeType="application/pdf" />
<data android:pathPattern="*.pdf" />
<data android:host="*" />
</intent-filter> </activity>

What is the recommended way to launch the messaging app (for sending an MMS message) via an intent? The following code works on my HTC Magic ... code..
... but it first launches the Resolver activity (com.android.internal.app.ResolverActivity), prompting the user to select the appropriate app (Email, Gmail, Messaging, Picasa). The user has to select Messaging before proceeding.
The only way I've found to bypass the resolver is to explicity set the desired component on the intent before starting the activity as follows:
intent.setClassName("com.android.mms", "com.android.mms.ui.ComposeMessageActivity");
However, I'm guessing this approach will not work on devices that have a customised UI, like the HTC Hero. Can someone confirm/deny?
I'm also struggling to find official documentation for the "address" and "sms_body" fields that can be supplied as extra data as per the above example. Is it expected that these will be supported by the default messaging app in future SDK versions and in customised UIs (like HTC's Sense UI)?
