Android :: Sample Or Tutorial In Using OpenGL In A Live Wallpaper In SDK 2.1

Jan 14, 2010

I've been checking out the Canvas-based "CubeLiveWallpaper" which uses Paint to create a rotating 3D Cube and it works very well. I've been trying to get my head wrapped around how to move/port the GLSurfaceViewActivity/CubeRenderer/Cube from the API samples into a Wallpaper Service but I'm not having much luck.

Basically, I'd like to take the OpenGL cube from the API sample and turn it into a "Live Wallpaper." Does anyone have any ideas, samples, examples I could work off of or where to get started?

Android :: OpenGL Speed Issue - Code Contribution To Other OpenGL

Feb 25, 2009

Single Threaded OpenGL game ! (check bottom, you can download and use the helper class) Lighting disabled ! Depth Buffer disabled ! Culling enabled ! Textures disabled !

Just 176 integers (x,y values only) making 88 vertexes along with 132 index numbers making "44 triangles only"

Framerates I get is

with GL_BLENDING disabled - 145 fps approx only! enabled - 110 fps approx only!

I have the screenshot of exact code in the draw function here.. just 2 damn lines ! I have hidden only the comments.. click here to see it http://prasna991.googlepages.com/drawframe.png

variable details in the 2 lines of code =========================== ipts = 176 elements (only x and y for each vertex) totallinetriangles * 3 = 176 lineindexes = 132 elements - type "short"

Here is the screenshot of output drawing and how it will look like http://prasna991.googlepages.com/screen.png

OpenGL single threaded Initialization Helper ================================ Here is my OpenGL helper class.. makes the OpenGL initialization for newbies a cakewalk http://prasna991.googlepages.com/OpenGLHelperclass.txt

I tested by rendering on the touch event only.. frame rate drops only when u touch and drag and here I have just tested by tapping and releasing gently on the emulator and on the device

Is this the device limitations ? So graphics is actually a lot lot lot slower than on iPhone ?

Android :: NDK OpenGL - Mixing Java And Native - C - Calls To OpenGL API

Jul 24, 2010

I would like to be able to use the OpenGL API from both Java and C (via NDK).

In Java, there is a GL object passed, which has all GL methods on it.

In C, you just talk to the native library.

In a single onDrawFrame callback (for which Java is passed a GL), can I use methods on the GL object, and also call NDK methods which access the openGL library?

In other words, is the GL object just a wrapper for the same instance of the native library?

Android :: Change User Interface Of Droid?

Sep 29, 2009

In Android, how can I replace the user interface of an emulator by my own interface? I would like to start my own interface immediately as the emulator gets started and that the user can't use the original interface but the original interface is on the background.

Update:

Now my code looks like this...

As I run the program, Eclipse displays

ActivityManager: Warning: Activity not started, its current task has been brought to the front. Does anyone knows why?

Android :: Droid Notepad Tutorial Crashing / Why This Is Happening?

Feb 9, 2010

I'm trying to run the Android Notepadv3 app on the Motorola Droid. When I am creating a new note, if I rotate my phone so that the view should switch to horizontal, or if I open it up so the keyboard is exposed, the app freezes and crashes.

I haven't modified the program in anyway from Exercise 3 solution (http://developer.android.com/resources/tutorials/notepad/index.html). Any ideas why this is happening?

Nov 25, 2009

I did a search and all I came up with is people trying to stream audio via bluetooth. One of the nice features I am a little envious of the ipods having is that about every stereo out there has an interface to control the ipod remotely. Is there anything similar available that works via the USB for android devices?

Jan 19, 2010

I know about camel case rules, but I'm confused with this m rule. What does it stand for? I'm a php developer, "we" use first letters of variables as indication of type, like 'b' for boolean, 'i' for integer and so on.

Is 'm' a java thing? Does it stand for mobile? mixed?

HTC Droid Eris :: Upgrading To 2.1 Tutorial

Mar 7, 2010

UPDATE: 06/14/10
I'm back on the forums, FINALLY! I finally got fed-up with dealing with Verizon and their rediculas prices. I had 2 phones on my 700 Family Share plan and it was nearly $160 with NO extra features. Just phone. Not internet, no texts, basic NON3G phone.. Looked into other carrirers and found Sprint... What is that? It's HUGE!... It's the EVO 4G. I'M THERE! I am spending the same each month as I was with verizon, with a Smartphone plan. I love it!

Fallow me on the HTC EVO 4G section! http://androidforums.com/htc-evo-4g/

IMPORTANT UPDATE: 04/03/10
I had to make a choice between my Droid Eris and purchasing a vehicle for the future. Of course, the vehicle won; so I no longer have the Eris *pout*. I hope everyone has fun with the future updates and conversations regarding the Eris and 2.x updates. I thank everyone that has helped me out and the 50+ who thanked for this Thread.

Motorola Droid 2 :: I Can't Stand Contacts Interface

Sep 17, 2010

I'm still a noob droid owner so maybe I just don't get it but here are some things that drive me nuts with the contacts interface.please note* I have (2) gmail email accounts, and a facebook account.
1. some of my contacts say they have "profiles" linked. so I tap the profiles and it will say for example "google: bob, google: bob, phone contacts: bob" why? I don't want anything linked. I feel like I don't have any control over my contacts.
2. I noticed that my fiance is a contact "julia" and then today I noticed another contact with her full name and a picture. so I ctapped that to investigate and it was her facebook info and email. where the heck did that come from? why on earth would I want more than one option for her as a contact?I am really lost. I mean REALLY lost. it took me a while to figure out how to make contact groups, so that I can organize some of my professional contacts but the rest of this is killing me. I created a new professional contact which happens to be a pest control guy. I chose to create a new contact. I entered his name and phone number, also email address. then I saved it. then when I looked at it somehow it had 3 linked profiles like what I was saying in point #1 above. what the heck?Why can't I just have a contact list period. and the only thing in this contact list are contacts which were entered into the phone by me. for each contact, I have the option to store their many numbers, email, etc. so when I tap on contacts, I get a contacts list and not a thousand people some of which are duplicates, some of which are emails I've responded to in gmail who I never talk to like customerservice@whateverbusiness.com.I'm mystified. can someone explain to me that either I am confused or this system is over complicated?
