I have created a subclass of Activity, 'CustomActivity', that overrides the onCreateOptionsMenu and onOptionsItemSelected methods. In a couple of other applications I have extended this subclass to provider a common menu for each activity. Is it still possible to access the resources from this Subclass? By default it uses the resources from the current activity (Strings, xml layout etc.).

What's the best way to access the drawable resource from within ItemizedOverlay as you can't access it directly like in an activity? The only idea I have for now is to pass the resources as a second argument...

View 3 Replies View RelatedCan a core class such as "AbsListView" access resources, such as xml files, and .png's, in a 3rd party app installed in the normal way (at the app level)?
I realize this is a change in framework code, and that is fine for my purposes. So, for example, if I know that I am going to install an app called "MyApp", could I go into frameworks/base/core/java/android/ widget/AbsListView.java and tell it to use an xml file and .png's that live in that app? Here is the line I would want to modify: setSelector(getResources().getDrawable( com.android.internal.R.drawable.list_selector_background));
So I'm defining a class that sets a Drawable attribute in an object. The problem is that I can't access the getResource().getDrawable(int resourceId) method unless I have some Context.
So what I did was to send to that class an activity instance (let's call it "act") and then I did:
act.getResources().getDrawable(R.drawable.whellchair)
but, when executing that line it throws a NullPointerException.
When idea how to accomplish this?
We have a website that makes use of OAM for single sign on (form-based authentication). When we submit credentials to WebGate / Access Server the authorization succeeds, however after the authentication is performed, the form action (as configured in the Authentication Scheme - with passthrough:no) returns a server error instead of redirecting to the originally requested URL.
If we use Mini Opera, we are able to get authenticated and forwarded properly.
This problem happens on numerous Android phones (versions ranging from 1.5-2.2), as well as the Emulator provided with the SDK.
This is proving to be a real problem as the default browser on Android phones is not able to get access to our sites(and this is the only browser that is having this problem).

How does one go about listing the resources that are available in an application?
For example, I would want to find the names of all files under /res/ xml.
Reflection on the R class didn't seem to work since the identifiers are static constants. R.xml.class.getDeclaredFields() doesn't return any fields.
The AssetManager didn't seem to work either because these are not raw assets.
Does anyone have ideas or examples?
I have big files to integrate into my application (videos), and thus for not not that my application occupies all the internal memory of the telephones, I saw that it was possible with Froyo to install the applications on the SD card.
I thus have to test this solution and my application settles down well on the SD card, the only problem it is that the system installs all the same my files videos (which are placed in the file /raw) on the internal memory of the telephone. Thus my question it is where to place my videos or where to make so that these also settle down on the SD carde ?
I created an application which is displaying camera preview. When the application terminates I noticed that some processes are still running. Also if I try to run the original camera application it displays an error (obviously due to the active process which belongs to the custom application).

So I'm struggling a bit with what is probably a fairly basic concept.. Activity Lifecycle.I have read a bunch of thread on the topic, and I feel I understand well both the functionality, and rationale behind the lifecycle model implemented for Activities, but it raises a bit of a problem for me. My app (game) has a couple of distinct Activities for various sections:
1. The TitleActivity is a very small Activity that just launches a GLSurfaceView and renders a startup logo.I use this to detect the OpenGL capabilities of the device (eg so I know if it's using a software renderer)
2. The LaunchActivity is the main menu screen where the user can access options etc and start a game
3. The GameActivity will either launches a GLSurfaceView or a standard View depending on hardware capabilties.
The issue I am having is that I want to pre-load some "slow-to-load" resources, specifically audio, in the Title Activity so when the Launch Activity renders I can play some background music.I have the concept of a "media library" which I use throughout the game.Because of memory limitations in the SoundPool, I have limited this to only absolute real-time sounds and all others are played using mulitple instances of MediaPlayer.Hence my media library has a bunch of pre-loaded MediaPlayer instances which I access regularly during game play.. so it makes sense to have a centralized access point for all audio.All fine, however the problem is that when I launch one activity from another.. for example the TitleActivity starts the LaunchActivity (via a call to startActivity(Intent...)), the former goes through the onDestroy stage of its lifecycle.Now logically I had assumed that if I allocate a bunch of resources in the onCreate of an Activity, I should clean them up in the onDestroy, however in the case of my "media library" if I load up the audio files in the onCreate of my TitleActivity they will be torn down when the LaunchActivity is started because the TitleActivity will have its onDestroy() method called.
I created an application which uses camera and during the appplication execution the screen is always on.
In the onCreate() method I added the lock code...
But after the application termination the screen remains on all the time and if I run the camera application it encounters an error which obviously appears because the camera resources are not released.
Does anyone know how to release all resources on application termination?
The code I am trying to implement includes a service and an application. When the application is first launched, it starts the service using the
startService(svc_name) call. Here svc name is an intent pointing to the class that runs the service.
I want to share a resource(file/socket connection) between the service and the application. For example one writes to a file and another reads from it. I am unable to get proper sync between the service and app. Could you please let me know how this can be achieved?
The Android documentation says that best practices are to make two drawable directories - one for HDPI and one for MDPI. It also says that if the MDPI directory doesn't exist and a MDPI device is running the app, it will scale down the HDPI ones so everything looks good. Is there any reason not to just make one high resolution set of graphics? One con that I can think of is performance issues and one pro I can think of is only having one set of images for your app.

View 5 Replies View RelatedIn my Android project, I want to loop through the entire collection of Drawable resources. Normally, you can only retrieve a specific resource via its ID using something like:
InputStream is = Resources.getSystem().openRawResource(resourceId)
However, I want to get all Drawable resources where I won't know their ID's beforehand. Is there a collection I can loop through or perhaps a way to get the list of resource ID's given the resources in my project?
Or, is there a way for me in Java to extract all property values from the R.drawable static class?
I want to add a big feature to an application i am developping, but as this feature interest few people and is quite independant from the main part, I would like to put that in a seperate "plugin" application.Does anyone knows any design patterns, snippets, "reference" examples about such design?In particular that separate plugin application should be able to access some tables in the main application DB. Is it possible to do that without broadcast receiver? - the main application uses a TabActivity: is it possible that a the tabactivity instanciates an Intent Activity that is part of the plugin? - does the plugin can access main application preferences (not sure this would be necessary, but better to anticipate the question!) is it possible from the plugin to access main applications ressources?At least the 2 first points are mandatory for me.
