Android :: Maximum Depth Of Activity Stack
Aug 20, 2009Is it necessary to limit how deep the activity stack can become within an application?I'm implementing a browser-type app. Every time the user clicks a link, I could launch a new PageView activity, but then the activity stack might become very deep. Alternatively I could have a single PageView activity that changes its content when a link is clicked, maintains an internal history and overrides the BACK button.Is there anything performance-wise to choose between these two designs? Is it OK to let the activity stack become arbitrarily deep?

Apr 29, 2010I'm currently learning OpenGL ES programming on Android (2.1). I started with the obligatory rotating cube. It's rotating fine but I can't get the depth buffer to work. The polygons are always displayed in the order the GL commands render them. I do this during initialization of GL:
CODE:...........
On surface-change I do this:
CODE:............
When I enable backface culling then everything looks correct. But backface culling is only a speed-optimization so it should also work with only the depth buffer or not? So what is missing here?

View 2 Replies View RelatedGeneral :: App That Opens Window With A Group Of Apps?
Dec 24, 2012AOKP has the option to enable/disable soft keys. For each soft key I can choose an app that should open when pressed. I would like to have a soft key that opens a group of apps. Example: The first "Soft key" (with a message-icon) should open a dialog window containing sms, contacts, phone, gmail, mail and so on.
Any app with which I can create such a group shortcut? So this app has to open a group window with selectable apps when started.
Android :: Enable 24bit Color Depth In The Emulator
Jul 6, 2009Currently, I am targetting the emulator to make Android application which is targetted for an Android device which includes 5" 24bit display. Only currently android emulator (or android in general) only appears to support 16bit. Meaning we are experiencing dithering issues why it isn't really necessary. Now my question can I somehow recompile Android 1.5 emulator image so it's using 24bit instead?
Or is this impossible without a lot of changes? Currently, I am predithering the images but no fun ;)
Android :: Could Play RGB 24-bit Color Depth Format Video
May 19, 2009Dear Sir, As I know, Android only supports RGB 16-bit color depth format. Could Android play 24-bit color RGB format video and REALLY see 24-bit color now? If it is not, will it be supported by Android Donut in the future?

Jul 4, 2010I just received my HTC Desire on Orange, rooted and de-branded it. Works fine now, I'm on SW version 1.15 as otherwise, I get issues on Orange.
However, the color depth on my device is very poor, it looks like it only has 256 colours if that makes any sense? A bit like on the old PCs when you rebooted and your display graphics drivers weren't properly installed.
Is there any way I can reinstall display drivers on Android? I hope this isn't a hardware issue.

Aug 18, 2009About the color depth on the Samsung Galaxy.
While it is advertised as having a 16 Million color display (24bpp) it is only running at 16bpp: $ cat /sys/devices/virtual/graphics/fb0/bits_per_pixel 16
Some say that it is a restriction of Android 1.5 itself which was only capable of supporting up to 16bpp screens. Android would be down sampling to 16bpp whatever the screen supports.
I've searched the available documentation over and over and can't find anything like that.
As I see it Android 1.5 would indeed be capable of displaying 24bpp images properly given that the screen is capable of and configured to do so.

View 2 Replies View RelatedAndroid :: Understanding How Activities Work
Jul 22, 2010I'm trying to wrap my head around activities and how they begin and end in Android. I've read what the Developer Guide has to say regarding activities and I'm still a little fuzzy on how I should appropriately handle their navigation in my application. As an example, say I have a main activity that starts a secondary activity. Once the secondary activity has completed it's purpose, I want to close it and return to the main activity. I recall having read that the activity stack was just that, a stack of activities that are pushed and popped. So I assumed that calling finish on the secondary activity would return me to my existing main activity. Calling finish on the secondary activity didn't actually do anything, visibly at least. Is there further reading that anyone can recommend to me? Chris Stewart cstewart@gmail.com http://www.androidsdkforum.com

View 2 Replies View RelatedAndroid :: Not Understanding Activity Stack?
Dec 3, 2009I'm having trouble with my activities when they go in the background. I have two activities, A and B. Only A can launch B (manifest copied below).This is very confusing. It's like Android knows my app is running, and puts a new instance of A on top of the old B instance running. I'd just expect that the application gets paused in-place, and whenever the user hits the app icon again, it just picks up where it left off (in this case, just show B again!) Below is the manifest, and the activity classes for this test are completely empty (except A which has a button to launch B).
View 4 Replies View RelatedAndroid :: Understanding Content Providers ?
Mar 1, 2010I am having trouble understanding content providers in Android. Do you use intents to call content providers as well as managed queries?
Also, an activity has an intent filter. The intent filter has a element which has a mimeType attribute. How does Android know which content provider this mimetype is referring to?
The tag in the manifest just lists an authority but not the full content_uri. Further, the content_uri is typically defined in an encapsulated class that seems to only consist of constants but no methods, so I don't see how that links over to the content provider class.
Android :: Understanding Broadcast Receiver / Way Of Activate It
Mar 25, 2010I am trying to understand the use of the broadcast receiver and the way of activate it. There's two ways isn't it? Register it from an activity or declare it in the manifest. So my question is: If I code a broadcast receiver which is watching incoming messages and I register it in the manifest, when a message comes my broadcast receiver will catch it automatically although any activity of my app had registered it. In a nutshells, I don't have to activate it so it works, only register it either in the manifest or in an activity.

May 19, 2010I'm attempting to add four controls to a layout; <label> <text> <seek> <radio> I want the seek widget to occupy all the available screen space between the edittext control and the radio control. However if I give it the value android:layout_width="wrap_content" only a small seek control is displayed and if I set the value to fill_parent it overwrites the radio control. I would have thought there would be a mechanism to occupy the free space between the text and radio controls dynamically.

View 1 Replies View RelatedAndroid :: Understanding ContentObserver Life Cycle
May 9, 2010The core of this Widget is an AppWidgetProvider which registers a ContentObserver to the CallLog content URI. This means that my widget is updated every time a call (incoming, outgoing, missed) is recorded. This works fine for a while, until *something happens* and my ContentObserver stops getting called (no error message seen in trace). I would rather that this ContentObserver persisted until the user removes the Widget.
I am guessing that my JVM has been destroyed (due to low memory?), ContentObserver garbage collected and/or ContentObserver unregistered (or just pointing to nothing), but I don't know how to debug this without restarting my code (and thereby re-registering). I can hide this bug by periodically re-registering my Content provider, but I would rather understand the cause and have a more optimal solution..............
Android :: Understanding Life Cycle When Screen Goes Off And On?

Android :: Understanding Proper Alarm Flow
Jan 11, 2010the app I'm trying to implement allows the user to select a sound file (MP3 or WAV) to play at a specific date and time showing a dialog with a progress bar and an OK/Cancel button allowing the user to stop the playing of the sound file. I want it to behave something like the countdown apps I've seen or even the built-in alarm clock app. As I'm implementing this simple (I thought!) app, I'm trying to better understand the platform and make the application conform to the Android way.
As I've been writing the app, I learn more about how things are supposed to work on the Android platform. And here's where I'm getting a bit confused. During my attempts to get the alarm to fire and display, I'm learning that properly formed Android applications are not supposed to show dialogs as a result of a background service or broadcast receiver being invoked through Android's alarm service. Instead, I think, the app is supposed to use a notification on the status bar to alert the user. The user then has the option to look at the notification to see what the app is trying to tell them..............

View 2 Replies View RelatedAndroid :: Not Understanding A Basic Concept Of Application Development
Aug 26, 2010First and foremost, are there many android developers here? Is this a good place for Android related discussions?I seem to be missing a rather large concept of Android development. The gist is I am struggling understanding how to tie an application together. I'm not sure how to explain it, so I thought I would do my best with an example from the Android ApiDemo... assuming you are familiar with it.
Inside the com.example.android.apis.view namespace of the ApiDemo, there is a class called Animation3.java.Animation3 inherits the activity class and there is some code inside to display animation.I can't find a reference to the class (Animation3) anywhere in the demo code (except for its definition obviously). The only mention I found is in the manifest xml file. So how the heck does this activity get started? Don't we need to create an instance of the class somewhere and fire off a method to start it? I don't understand how to generate the code that ultimately glues this class to the rest of the application.Additionally, what about other classes like views or viewgroups? How do I generate code outside the class that initiates/starts/uses/calls (insert proper term) the class.I would appreciate any code examples as well as any concept explanation or reference documents. So far I've read pages and pages on activities and views but I'm really struggling how to tie things together.
Android :: Understanding Custom Components And Multiple Resolutions
Dec 21, 2009I had posted a similar thread a while back and received no feedback, so let me try to be more clear.I am able to use Androids components to build the most basic layouts, which include images, buttons, text areas, etc. These are like Android Lego! I can build the castle. BUT I want to design my own component, my own Lego, that draws on the screen and uses the available area that the Android components have not used. ie, I want to have a top layer of buttons, and the rest of the screen, whatever it is, I want to use to draw 2d graphics. So, I want to make my own Lego, and use it with the other Android Lego. However, I'm also trying to be a good developer and making this for whatever resolution is thrown my way. What is the best way to do this considering the deluge of different resolutions Android developers must cope with? Is there a way to do a table view and return the remaining screen size? Or, am I stuck making an entire new box of Lego here?
