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?
I am looking for some sample code or tutorial that sets up the most basic opengl es application.
for example, just do glClear() in the renderloop.
i have already been searching the web but all i found was either out of date or too much and too complicated.
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 ?
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?
I cannot find any tutorial on the web. How can I do it in a simple way?

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.

Is there anything similar available that works via the USB for android devices?

Here's my story.
I downloaded the NotePad tutorial project exercise files.
I created an Android project based on the tutorial files for the completed exercise (located in the Notepadv3Solution folder)
I run the project and bellow is a screenshot of what appears:
It doesn't seem to be working properly.
Could it be because I'm on version 2.2?

We are developing a software suite that heavily involves user interaction. We'd like to have a nice touch-based user interface, very similar to that of Android. Are there any libraries or other ways to easily build and use such user interfaces for own applications. We mainly develop in C++, but things in Python or Java or even something web-based..

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!

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.
So I've searched high and low and can't figure out a good (idiot proof) tutorial for setting up adb? Can someone put one together (for windows) or point me in the right direction? I currently use terminal for almost everything, but most people write their tuts for adb. If you write one, please start simple and at the bottom and work your way up.

View 9 Replies View RelatedI'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?
If there is any way to make it so that the stock messaging interface shows the contacts picture, like with facebook messages in the universal messaging app?
