Android : Launch Browser Intent With Custom Class - Cannot Find Activity

Jul 25, 2010

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.

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 :: Launching Intent From Class Outside An Activity

Jul 28, 2010

I've got two activities, one of them is called MyActivity. I want both of them to be able to use a function located in a class othat we may call MyClass. In MyClass, I try to use an intent to launch the activity AnotherActivity. Since the constructor takes a context as parameter, I simply tried to store a context from the activity in the constructor, and then use it when I try to create my intent.However, even thought none of the arguments are null (checked that with a simple if-statement), intent seems to be null and a NullPointerException is thrown. Why does it not work, and what can I do to solve the problem?
I'm quite new to Android and Java development, so please explain it as basic as you can.

Android :: What Is The Significance Of Context In Various Constructor Of Intent Class When Starting An Activity

Mar 4, 2010

I had come across a code snippet which calls for an activity without referring to any context. Before, i was considering that context is used to tell about the calling component. But as i came see that another component can be called without any reference to context, it makes me wonder what purpose it might be serving. please put some light on it.

Here is the code which calls for an activity without referring to 'context'

Android :: Communicating Between Receiver Class And An Activity Class

Jul 14, 2010

I'm just getting into Android development, and I have a question about communicating between a receiver class and an activity class. I'm very new to JAVA and Android so I hope I don't sound too stupid. I'm developing an application where I intercept an SMS message and then based on various elements of that SMS I might delete it once it's been saved to the inbox. I have a receiver class that intercepts the txt message, and I am also able to delete messages from my inbox with code in the activity class using a button at the moment. The problem I have is communicating between the receiver class and the activity class where the code to delete a message resides. I tried putting that code directly into the receiver class but as I'm sure most of you already know the BroadcastReceiver class doesn't seem to support what I need to delete messages. I've been searching for an answer to this for a while, but haven't been able to find anything. Honestly I'm not sure I know enough about JAVA and Android to even recognize a solution if I saw it.

str = s;
}

Android :: Launch Messaging App Via Intent?

Jan 13, 2010

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)?
