Android :: Correct Intent Filter Configuration To Associate File Type?

Nov 10, 2010

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>

Android :: Retrieving File Path When Using Intent Filter

Oct 5, 2010

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?

Android : Way To Associate App With File Format?

Jun 5, 2010

I am writing an app that needs to be able to open (be associated in the browser download window for example) with a certain file type. The file type has .emx extension and is in an xml format (the top of the files have <?xml version='1.0' encoding="UTF-8"?> ). However, I can't for the life of me get my app associated with this filetype.

Android :: Intent Object Not Triggering Filter

Jun 25, 2010

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 }

Android :: Intent Filter For Http Scheme

Sep 14, 2010

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?

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?

Android : What Is An Intent-filter Show An App When Sharing A Url?

Nov 5, 2010

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.

Android :: Creating Intent With Action / Any Way To Filter Results

Jul 20, 2010

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?

Android :: Catching An Action Without Setting An Intent Filter?

Jan 11, 2010

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...

Android :: Filtering Urls Within An Activity's Intent-filter?

Feb 6, 2010

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?

Android :: New Activity Instance Created For Every Intent-filter?

Feb 6, 2010

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.

Android :: Default When Using Multiple Actions In Intent-Filter

Jul 6, 2010

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?

Android :: 1.6 SDK Level 4 Project / Receiver Intent Filter Never Invoked

Apr 4, 2010

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.

Android :: Specify Scheme Specific Part In Data Tag For An Intent-filter?

Feb 3, 2010

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?

Android :: Intent Not Opening Correct Activity

Aug 22, 2010

I'm having a struggle understanding why my intent is not working. I basically just copied paste from other examples in my code that work perfectly like this. Here it is:

Intent addIntent = new Intent(v.getContext(), thenNnowMode.class);
Bundle w = new Bundle(); String activityName = "addPic";
w.putString("activity", activityName);
w.putParcelable("bitmap", selectedDeviceImage);
//a.putString("id", picId); addIntent.putExtras(w);
startActivity(addIntent); finish();

The intent is opening a different class called thenNnow.class instead of thenNnowMode.class and I have no idea why this is happening. I've tried sending the intent to open other activities other than thenNnowMode but it always opens thenNnow. Am I missing some silly syntax mistake? It's so strange, its the same code. I am not sure if it's relevant but the thenNnowMode class uses the device camera

Android :: Taking Picture By Camera Correct Intent Action

Mar 3, 2009

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?

Android :: Correct Intent To Launch Gallery / Video Camera

Jul 28, 2009

My application has buttons to launch gallery and video camera apps but the below code only seems to work on phones with the standard Cupcake build:
// For Gallery Intent intent = new Intent(); intent.setClassName("com.android.camera", "com.android.camera.GalleryPicker");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); mContext.startActivity(intent);
// For Video Camera Intent intent = new Intent(); intent.setClassName("com.android.camera", "com.android.camera.VideoCamera"); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); mContext.startActivity(intent);

On rooted / non-cupcake phones, I get this error:
android.content.ActivityNotFoundException: Unable to find explicit activity class {com.android.camera/com.android.camera.VideoCamera};
have you declared this activity in your AndroidManifest.xml? at android.app.Instrumentation.checkStartActivityResult (Instrumentation.java:1480) at android.app.Instrumentation.execStartActivity(Instrumentation.java: 1454) at android.app.Activity.startActivityForResult(Activity.java:2656) at android.app.Activity.startActivity(Activity.java:2700)

Android :: Intent Action - Correct Way To Get Back To Application After Call?

Aug 27, 2010

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.
