Android :: Background Activity For Map Started Again When Orientation Change

Apr 6, 2010

i've developed an android app that's fetches an xml file and displays this data via several markers on the map. This works fine so far. The problem right now is that when i switch the orientation of the phone (portrait->landscape or vice versa) the markers disappear for a small moment, the xml processing is started again and then they reappear. Is there a way to prevent this re-loading of the file? It only takes about 2-3 seconds.

Android :: Start Activity When Main Activity Is Running In Background

Jan 10, 2010

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)?

Android :: Does Change Background Will Change Padding Of Linear Layout

May 21, 2010

I have the following linear layout. What I don't understand is if I set the background to another image, the padding information are reset. Is there a way to prevent this?

<LinearLayout android:id="@+id/aPanel"
android:orientation="horizontal" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:background="@drawable/bkground"
android:paddingLeft="15dp" android:paddingRight="15dp">

<!-- some children here -->
</LinearLayout>

I see the position of the children get shifted when I change the backround drawable of the linearlayout 'aPanel'.

Android :: Orientation Change Crash In Tab Activity With List Activity

Jan 21, 2010

When views with different type have same id and screen orientation changes,

either java.lang.ClassCastException: android.view.AbsSavedState$1 or java.lang.IllegalArgumentException: Wrong state class -- expecting View State will occur. (depends on the view's order)

Because View.dispatchRestoreInstanceState() checks id only.

You may wonder why anyone would make views with different type to have same id.

But it can happen when you use tab activity.

Imagine you have tab activity with two children activity.

Tab1 is ListActivity and Tab2 is ExpandableListActivity.

Both activity have id of "@android:id/list" but the type of view is different.

This means we cannot use ListActivity & ExpandableListActivit at the same in one tab activity.

Android :: Change Intent Bundle Data Before Activity Recreated After Orientation Change

Jul 30, 2009

I have a notification that starts my activity and passes a messages using the intent's putExtra() function. The message is then displayed to the user in the activity's onCreate function. When the application is restarted due to a orientation change, the message is shown again as it is still in the intent's bundled data.
How can I remove the extra data?

I tried the following:

Bundle bundle = getIntent().getExtras();
if (bundle.getBoolean("showMessage")) {
// ... show message that is in bundle.getString("message")
// remove message
bundle.remove("showMessage");
}

But the message will still be shown after the orientation changed, seems like the intent used is not the one I changed, but the original one. The only workaround I found is to save the showMessage additionally in onSaveInstanceState(). Is there another way? Or is this the way to go?

Android :: Activity In Background ?

Nov 19, 2010

Is there a way to 'preload' a user interfaces but to not display it until I am ready?

I have a service which has a receiver to listen for action_screen_on to occur. When that occurs, I would like to load an activity. However, as it is now, it takes about 1 second to load. I would like to preload the layout in advance so that when the screen is turned on the layout loads as soon as possible.

Android :: Activity Background Processing

Apr 17, 2010

"Note that when you write an activity, you can make it stop or continue running when it is moved to the background (see onStop() in Activity Lifecycle). For activities that download data from the network, it's recommended to let them continue downloading so the user can multi-task." As far as I was aware I had to create a service if I wanted to have a background activity such as a media player, internet download, or processing of data in files on the SD card continue when the activity was no longer in the foreground.I went and reread the onStop information on the "Activity Lifecycle" page, which was referred to. But I didn't find any mention of how an activity might continue to run in the background after onStop was called.

Android :: How To Detect An Activity Goes Into Background

Aug 5, 2010

I need a way for my Activity to known that it's going into the background, and not when it's getting killed. I thought about hooking at onStop(), but onStop() is called for both cases. In other words, is there a way to tell if when my Activity is moving into the background and not getting killed?

Android :: Activity Should Be Transparent / But Has Black Background

Apr 22, 2010

My use case is writing an overlay controller activity for a landscape camera preview. I followed the instructions from a couple of tutorials for writing a transparent theme.When I start this activity from my root activity, the layout gets drawn correctly, but the background stays black. I tried to use @android:style/Theme.Translucent instead, but this Theme inherits the orientation from the calling activity (landscape) and thats not what I want.The application holding the camera preview is set to landscape view as it does not display the preview correctly in portrait orientation. (see old google bug report)What I wanted to do was to put an independent activity for user interaction interface in front of the camera surface holder (this activity should be set to 'portrait', or even better to 'sensor')

Android :: Set Solid Background To Spawned Activity

Sep 9, 2010

I'm not very familiar with the android SDK yet. I have an application (game), which is developed mainly using the NDK, and uses egl to render. i have an activity which handles the egl swapbuffer and runs the games native main loop, pretty straight forward I guess.

Now I have made another activity which host a TableLayout containing an EditText as well as a button (simply for text-input later used by the game). I spawn this activity from my main activity using startActivityForResult. The small problem I'm having now is that I can't manage to make this "popup" activity to have a background, so my paused game will reside in the background, with the various widgets just overlaid. This is not very pretty in my opinion, and I would like to at least have a solid background color for my spawned activity while it's active. I *could* just simply go into some state in the games main loop which clears the gl-screen just before I spawn the new activity. But I don't like this solution and it's a tad more work then I'm prepared to put in just at this time in the project. I'm pretty sure there is some simple way to just set a background color somehow, I just can't find *any* way to do it, I've looked around in the SDK resources and tried to search for any hints towards this, but i'm just not familiar enough with the java SDK to find what i'm looking for.

On a side note I would also like to be able to center the EditText widget as well as the button on the screen once the Activity is active, I haven't looked very deeply into it yet, but from a quick glance of the documentation I couldn't really find any suitable positioning methods in the tablelayout class. But as I said, haven't looked very hard. Can probably solve that one easy, but i'm just throwing this in as well :)

Android : How To Add A Background Image To Droid Activity

Oct 12, 2010

My goal is to develop a GUI application on top of a background image with buttons in specific places on the image. The first step is to display the background.

The image can be displayed with resources and is described in several FAQs including this one:

how-to-add-background-image-to-activity

It compiles and runs without errors, but the background is black. Here is the main.xml file:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:id="@+id/rootRL" xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/background">
</RelativeLayout>

The image has been in png, 9.png, and jpg format with basenames of 'main' and 'background'. It builds but does not display. Making clean and recompiling does not help.

This behavior occurs on both the emulator and on hardware -- an Atmel AT91SAM9M10-G45-EK. The SDK version is 2.0.1.

Android :: Update Information In Activity From Background Service?

Mar 18, 2010

I am trying to create a simple Android application that has a ActivityList of information, when the application starts, I plan to start a Service that will be constantly calculating the data (it will be changing) and I want the ActivityList to be in sync with the data that the service is calculating for the life of the app. How can I set up my Activity to be listening to the Service? Is this the best way to approach this problem? For example, if you imagine a list of stock prices - the data would be being changed regularly and need to be in sync with the (in my case) Service that is calculating/fetching the data constantly.

Android :: Bring Activity In Background To Front Via Notification

Aug 5, 2010

I create an application which displays the notification when the service starts. If an user navigates to HOME screen (without exiting the application), the user could still go back to the previous application by pressing on the notification icon. This is very similar case as the track recording service in Google application "My Track".

I want the existing activity as Single Top activity since it has associated service running. However when my application tries to bring the existing activity to front via notification, the existing activity's onDestroy has been called which causes problem. How can I skip this onDestroy method? Here is my current codes:

Android :: Activity.finish() With AsyncTask Still Running In Background?

Apr 28, 2010

What happens on Activity.finish() with an AsyncTask still running in background?

Does it just pop the Activity off the Activity Stack, but wait to destroy the Activity object until the AsyncTask fully completes (since the AsyncTask is an inner class of my Activity)?

Also, would it act any differently if the AsyncTask were a public, non-inner class that held no references to the instance of the Activity?
