I'm launching a webbrowser via an intent, which allows my app user to login to Google Docs in a 2-legged oauth dance. This works fine, and the browser callback comes to my app with the right authentication string.
I just want to be able to kill that browser window once we are done - having it sitting there is confusing and messy.
How can I kill a browser window I started up?

I have an activity which shows some List entries. When I click on a list item my app checks which connection type is available ("WIF" or "MOBILE"), through NetworkInfo.getTypeName(). As soon as I call this method I get a NullpointerException. Why? I tested this on the emulator, cause my phone is currently not available (it's broken...). I assume this is the problem? This is the only explanation that I have, if that's not the case I have no idea why this would be null. Code...

I have an Android app that in the onCreate() method, preloads a lot of graphics.
When I test my app on my HTC Aria and launch it, it runs fine. However, if I press the back button to exit my app, and then launch the app again, it crashes with an OutOfMemoryError: bitmap size exceeds VM budget. If I then launch the app for the third time (right after it has crashed) it launches fine. Then if I close and re-launch it, it crashes again with out of memory. It continues this every-other-time-crashing pattern forever if I keep trying.
I checked to see what life cycle methods were being called and onStop() and onDestroy() are both being called when I exit the app, yet I have a feeling that something is not yet being cleaned up and that by "crashing" the app when I try to launch it the second time, it somehow free's the memory.
Any thoughts on what could be happening or how to remedy this? Please let me know if you need me to post more info.
Info: My app is fairly simple and only has 1 activity that plays some frame animations.
I wonder if this is a bug. This code works on Android 1.x, but fails on 2.x, generating a SecurityException whose explanation seems to have a null String in it where it means to describe the missing permission:
CODE:.............
I think that perhaps the issue is that the classname's prefix (com.android.camera) is not the same as the package name (com.android.gallery).
Can someone comment on what permission (if any) would actually permit this to work on Android 2.x?
The code is thuslike:

That message can occurr if the receiving code crashes or takes too long. I am writing an appwidget for my application, there are like multiple pending intents are there to launch an activity or receive a broadcast. The Problem I am facing is , some times I get exception saying that the Pending Intents cannot be delivered. And the widget does not responds to the touch from the user. please help me. I am not able to find any alternative also.

The project is about implementing an AbstractAccountAuthenticator with an AbstractThreadedSyncAdapter to sync certain data on a server with a content provider.
I made everything and both adding accounts and syncing is running without any problems.
Now I've tried to add a Preference-Screen just like suggested in the android reference (search for AbstractAccountAuthenticator, it is explained there) via xml like this:
autenticator.xml:
CODE:..........
The Preference-Screen-xml looks like this:
CODE:.....................
The screen is promted how it should be, but and that is the problem: When I click on the PreferenceScreen with the intent it leads to a crash of the system (both in the emulator and my HTC-Desire).
Logcat says:

I can't find any intent which opens the camera. The closest I've found is ACTION_CAMERA_BUTTON but that breaks if the phone has no hardware button for the camera.

View 2 Replies View RelatedWhat 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)?

There's seemingly no way to launch the calendar app in a generic way. I've written a widget which allows you to launch the calendar. I use the following Intent:
Intent intent = new Intent(Intent.ACTION_VIEW); intent.setClassName("com.android.calendar", "com.android.calendar.LaunchActivity"); startActivity(i);
However, this doesn't work on the Hero because HTC has apparently replaced the calendar in their Sense UI. I'm looking for a "standard" way to reach the calendar. I'd like for something like this to be standardized:
Intent i = new Intent(Intent.ACTION_VIEW); i.setType("text/calendar"); startActivity(i);
Does anyone think it would be worth trying to add this to the source? It seems like there is a missing chunk of standards around calendar events and/or iCal / vCal support. Does anyone know why?
I have found various topics here and elsewhere on creating an intent for sending e-mail and that seems to be pretty straightforward. I'm looking for an intent to just launch any e-mail client the user might have.
Here is the code I've seen for sending an e-mail (posted just for reference, this doesn't serve my needs as I don't want to send a new message):code...
The code above works but isn't flexible in that a user might not be using Gmail but the other built-in e-mail application or a 3rd party e-mail app. I'm looking for an intent that would bring up the chooser in this case so the user can decide which app to launch to read e-mail.
Does anyone know how to accomplish this?
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?

View 6 Replies View RelatedI have the url of an image. What i need to do is launch the default image viewer for images using an intent. But it doesn't work. If I do not specify the type of data, the intent launches the browser since the data is a url. It works basically (since you can see the image on the browser) but what I would like is to have the gallery display the image for me.I can also download the image into a Bitmap but I would still not know how to display the Bitmap using the gallery (if that's even possible).I tried saving the bitmap to the cache and then launch the viewer on that file but it doesn't work.

This is what I would like to do: => IF WiFi is enabled AND active, launch an intent (in fact it's a WebView that gets its content=>the instructions of my app on the web) => IF NOT, then I would launch another intent so that I don't show a WebView with "Web page not available ... The Web page at http://www.mywebsite.com might be temporarily down or it may have moved ..."
I tought initially to use
if(wifi.isWifiEnabled())
but that does not say if the Wifi connection is ACTIVE or not. It says only that the user has turned the switch on. The device may or may not be connected... Is this correct ?

I'm using Wikitude API 1.1 as an AR viewer in my application. The problem with Wikitude, if I haven't launched the actual Wikitude application since the phone's bootup, I will get a NullPointerException everytime I start my own application.
So I figure if I can start my app first and them check if Wikitude is installed and or running. If it's not installed, go to market n download. If it's not running, then we should run it straight to background so that my app doesn't loose its focuscode...
The part I block commented is the intent to start Wikitude. But I always failed in restricting Wikitude to background. Any help?
