Android :: Start External App / Activity And Add My Own Header?
Jan 16, 2010
I am using Sygic Navigation on my HTC Hero. I can start it by calling the correct intent as I described here. Now, Sygic starts in fullscreen-mode and I cannot use the BACK-button to go back to my previous Activity (dont ask me why).
The question is: is there some trick or way so I can control how that Sygic Activity is started? I want to add my own "header" on top; the header contains my buttons for navigation. It would be great if I could add that header, then have Sygic below that (as the "content" then, as shown here).

I have touched on this question here, where Christopher gave an answer to this, but I dont really get it so I thought its time to make it a real question, not just a "follow up" =)
As it stands, the application Im writing has 4 different screens:
1. Screen 1 - list of nodes (main screen)
2. Screen 2 - options menu, tableLayout with buttons
3. Screen 3 - navigation
4. Screen 4 - text details on version etc
These screens can be navigated to/from using a "header" View that is placed on top. the header then has 4 different buttons:
+--------------------+
| menu with buttons |
+--------------------+
| |
| |
| |
| C O N T E N T |
| |
| |
| |
+--------------------+
The header is just an XML-file (header.xml) with a few buttons. That header.xml is the included in the Layouts using the include-markup. For example, the main.xml has the line:
<include layout="@layout/header"></include>
The header show up alright, but the question is - what is the correct approach to attach OnClickListeners for the buttons in the header?
Christopher pointed out that you could create an Activity class and do the hooks there, like this:
CODE:............
First, I cant make it work since the method setupHeaderButtons isnt accessible from FirstActivity.
Secondly, is this the right way to go at it?

My app is comprised of a set of reusable Activities that other apps can reuse. For various reasons, I would like my Activities to be launched in context of the invoking Activity's process, instead of always being launched in my Activity's process (default behavior on Android). How can I achieve this?

I'm working on a Application and I would like to start or call an external application from it by pressing for example a button...on my application.
The application I would like to call is an open source application.
I've read on the official android website it is possible to do it but haven't found any suggestion on how to do it.
MY APPROACH:
So trying on my own I've used an Intent Action and a button...like this
CODE:...............
RESULT:
When the button is pressed, A window appears which invites me to complete the Action I guess by choosing one of the Listed programs such as:
-Gstr
-Import Ics
-Market
-Music
-Mail (com.htc.android.mail) and so on...but not the API I was looking for...
When I choose Gstr(I guess is the application manager) then opens another window
Which shows a list of Installed Applications. From there I find the Application I was
Looking for and starts it (by long pressing on it's Icon...)
ISSUE:
I would like to start the external Application directly by clicking on a button on my application without passing through hundreds of others... Is there a way to achieve?

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 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?

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.

I would like my Activity to be informed when the SD card is removed, since it relies on files from the SD card (to keep apk size down) but for compatibility reasons is not targeted at Froyo. I'd like to close the application when the SD card is removed/mounted (giving the user a dialog message to inform them of course) so that I don't get IOExceptions etc (I'd quite like to not have to check everytime I load a file to see if the external storage is available, I already do a check on application launch). There doesn't seem to be any attribute in the manifest for this (like configChanges) that I can find.

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'm trying to do some dynamic code and I load a new class that's supposed to be an Activity and I want to start it, but using the regular startActivity(Intent) wants the Activity to be "Declared" in the AndroidManifest.xml file.

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.

My application has a background process which continuously waits on a socket for receiving messages and it should be started only once and at the time of application starting.Thus i want to do that background job in a service.
The service should not be started from the activity ,it should be started at the application starting.
How can i define the service,which will be started at the time of application starting?
If at all the service is started from activity.The activity can be destroyed and restarted.when this happens the service also be restarted .

My application has 2 packages because one is shared with my other applications. I want to start an activity of the shared package.
I tried the following: Intent intent = new Intent(); intent.setClassName(shardedPackageName,sharedActivityName); startActivity(intent);
It throws an ActivityNotFoundException and suggests that the activity might not be in the manifest. But how do I list an acitivity from another package in the manifest?
