Android :: Start An Activity In Different Apk Using StartActivity - Using The Activity Name Or Similar
Apr 20, 2010
I have tried to write an Android application with an activity that should be launched from a different application. It is not a content provider, just an app with a gui that should not be listed among the installed applications. I have tried the code examples here and it seems to be quite easy to launch existing providers and so on, but I fail to figure out how to just write a "hidden" app and launch it from a different one.
The basic use case is:
App A is a normal apk launchable from the application list.
App B is a different apk with known package and activity names, but is is not visible or launchable from the application list.
App A launches app B using the package and class names (or perhaps a URI constructed from these?).
I fail in the third step. Is it possible to do this?

My 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 have an application with contains multiple activities. The main activity will start the others ( use startActivity() ) depends on user event, when an activity close, it calls finish() and return back to main activity. It appears to behavior like that.
However, the "problem" I see is main activity's onCreate function is called every time. I think the the main activity should be placed in the activity stack and simply push to front when others exit, therefore only onResume, onStart are called. Is there some flag I need to set or I misunderstand the activity behaviro?
In child activity, besides calling finish() or startActivity for main activity, what is other way to move main activity to front?

I created an application which enables the user to set whether he wants to receive notification while the application runs in background mode. If the notifications are enabled an activity should be started (the dialog should appear on the screen).
I tried to enabled it the following way:
CODE:...........
This is the method from main activity. When onPause() is executed isRunningInBackground is set true.
When I tried to debug it when the main application was running in the background the line
startActivity(intent) had no effect (the activity didn't appear).
Does anyone know how to midify the logic in order to start an activity from the main activity when the main activity is running in the background (after onPause() is called)?

I have a huge maze of activities in my application. What I need to do, is that when the user logs in into the system, the activity history should be cleared. I cant just use finish() when I start a new activity, because I want the activities to have a history until the user logs in. I have experimentet with the different flags when starting an activity, but I have had no success.

Is there any event triggered on an activity when I call startActivity("activity_id", myIntent);
If the Activity exists already. I pass a parameter to the activity via i.putExtra("someID", someSerializableObject ); and would like to call a method to refresh a WebView. Right now, the call on startActivity brings the activity in the foreground but the webview does not display what i want.

I have implemented a ListView in my Android application.
I bind to this ListView using a custom subclass of the ArrayAdapter class. Inside the overridden ArrayAdapter.getView(...) method, I assign an OnClickListener. In the onClick(View v) method of the OnClickListener, I want to launch a new activity.
I get the exception:
Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?
How can I get the context that the ListView (the current Activity) is working under?

I would like to display a an access dialog activity at the start of my application.
In other words, I would like to start another activity (in dialog theme) as soon as my Main Activity is loaded. But, I know that I can not start an activity while another is creating.
I tried to start this activity in the onResume() method : I can see the new activity called, but the Main activity do not respond after closing the new activity.
Is there a solution to do this, without using delayed intent ? May i use a special flag for my intent ? I did not find, in the activity cycle, a way to detect the end of activity loading.

I've got an app that creates an intent for the last.fm android app in which it will start the "recommended" station for my account when i press a button. The trick i'm trying to figure out is how do i get the phone back to my app without the user having to navigate back manually? Once it start the last.fm intent it takes you to the playlist and i need it to resume back to my app automatically.

MyService and MyClient are both running, although MyClient is currently in the background. If MyService sends an Intent to MyClient via:
CODE:..............
How do I get this Intent in MyClient? Running this code triggers onResume() in MyClient, but because it's already running, calling getIntent() returns the Intent that initially created MyClient, which is always android.intent.action.MAIN

I am having two activities, say activity A and B. Activity A is an ListActivity, and when the items in the list is selected, it will call startActivity() to bring up B. The problem here is that when I am in B and click the home key, and then go to the application launcher to resume my application, A will be brought up again. This time when I click a different item in A, it will bring up B with the old data of the previously selected item before the home key was clicked.
After examinzing the code, I found that the startActivity does not update the intent of B. I found a post here about the similar question, and the answer was to overwrite the onNewIntent. However, I found that it doesn't work, because this method never get called when the second time I call startActivity. I am sure that this is the same instance, because I've printed out the instance number. Is there any other ways to update the intent of the activity? Or I need some other settings to make the onNewIntent get called? I didn't set any flags or launch modes, so everything is default.

I have created two classes: Example1 and Example2, which extends activity.
Example1 contains a UI of buttons, while Example2 contains UI of TextEdit.
I want to call Example2 when a button is clicked, so this code is in an onclick method
Intent i = new Intent();
i.setClassName("com.a.ui", "com.a.ui.Example2");
startActivity(i);
So I am able to get the UI of Example2 successfully.
What's an alternate way of calling intent?
Is there any alternate way to start an activity?

I am trying to make a PopupWindow show straight away when an activity has started.
when calling public void showAtLocation (View parent, int gravity, int x, int y)
I get the exception ERROR/AndroidRuntime(2500): Caused by: android.view.WindowManager $BadTokenException: Unable to add window -- token null is not valid; is your activity running?
At the moment I am calling from onCreate, but when calling from onStart or onResume it still gives the same error.
The activity api says the activity is supposed to be running after onResume is called. Where is the best place to load up the PopupWindow if it needs to be done straight away?
At the moment It looks like Activity.onWindowFocusChanged() is the best place.
