I was trying to open an Activity of an other applicatoin by using an implicit Intent. It doesn't work, I thought it is possible to start an Activity of an other Application by using implicit Intent. Or do I missunderstand it?
I added following intent-filter to the AndroidManifest of Application A:
CODE:..............
And called the Intent in Application B by using folloing code:
CODE:.............
All I get ist, the error message that Application A was stoped unexpectedly.
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:....................
implicit intent with class name as action defined in intentfilter. is not working. Only it it is defined as "android.intent.action." it is picked up ? is it so ?
I have app A with the following in manifest.xml file
CODE:.............
In app B, i tried to call the activity in A using below code.
CODE:.............
This code works. But not above line.
To understand the implicit intents by example.
View 2 Replies View RelatedI`m trying to develop an application, just to test the ability of android to call an activity with an intent based not in the specific class name but specifying the action, category and data information. Acording to this link
http://developer.android.com/guide/topics/intents/intents-filters.html
only three aspects are consulted when comparing an intent object to select the future activity to run. I created two android projects (and two activities), the first is the main project who sends the request and the second can be called directly or through the filter. This is the call of the activity in the main project:
CODE:..................
This is the part of the manifest that specifies (or at least I try to specify) in the secondary activity that it`s available to be selected to run with that information:
CODE:...............
I installed both separatelly and I was expecteing to see the second activity after the called but instead I got an ActivityNotFoundException. By the way if I comment the t3.addCategory (Intent.CATEGORY_HOME); line and change the t3.setAction (Intent.ACTION_EDIT); to t3.setAction(Intent.ACTION_VIEW); the browser is executed so I think the problem is in the manifest of the second activity.
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.
CODE:...........
One more app,which has two activities like below.
CODE:..................
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"
i.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 ?

View 2 Replies View RelatedMy app works with pictures. It can take multiple pictures as an input, process them, and send them again to another app.
As a consequence, my main Activity has declared an intent filter on ACTION_SEND_MULTIPLE for image/* mimetypes and can result in issuing a new Intent with the same action and data type using Activity.startActivity(Intent).
Is there a way to exclude my own activity from the list of apps that is displayed to the user after the startActivity() call ?
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?

View 2 Replies View RelatedI've searched for a few hours for a solution to this, so hopefully this isn't a repost I'm setting a shortcut on the Home screen which raises an Intent to my application - the problem is that I don't want to show my app, just run a little code and display a Toast notification. This must be possible - I just can't work out how.. Once I'm handling the shortcut Intent in onCreate() the UI has initialised and I get a little screen flicker if I then run my code and finish().
View 4 Replies View RelatedI have a service that is downloading a file. When the download is done, I would like to update my "Downloaded files" list in my Activity, but only if the Activity is running. I do not want the Activity to start if it's not already running. I was hoping I could do this by making a new Intent with some special flag. Anyone have any idea how I can achieve this? A tiny code example maybe?

Android will call onCreate() of my activity whenever it is launched.
In the onCreate() of my activity can I tell what intent launches my activity?
I want to have an image open from a URL to an intent, most likely the browser or maybe a picture previewer like the one built into twidroyd.I've gotten plain URLs to open to the browser. I just can't figure out what action or category to specify,
View 1 Replies View RelatedI'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
My program has a list of tabs that each contain a list of people.Clicking a person should edit their details, but instead, clicking a person throws an ActivityNotFoundException.
View 2 Replies View RelatedI'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.
I want to create 4(four) tab, on click of each tab i need to call some activity through Intent, upto this is OK, but without replacement of whole page, I would not like to replace tab, tab will remain (unchanged) same for each a every layout/activity, i.e, only lower part (content) parts will change.

View 1 Replies View RelatedI have a central activity that can be launched from two separate classes. I was hoping that in this central activity I could have an IF statement like
if(this.getIntent() == MainMenu.class)

But obviously that isn't legal so how could I structure an expression to check from what class an intent was started.
