Can somebody tell me if we could bind one object on to another in openGL ES.say draw multiple squares on the surface of a cylinder.I know we can draw them independently,but how to make them look like one single object??Is this possible?

I am trying to get a quite simple openGL ES 1 program run a smooth solid 60fps on a couple devices out there, and I get stuck on HTC desire. The phone itself is quick, snappy, powerful, and overall a breeze to use ; however, I can't seem to display anything fullscreen at 60fps with OpenGL. After getting stuck for a long time with my app, I decided to make a test app with code right out the sample code from the documentation.Here is what I am doing. Simple initialization code with GLSurfaceView. I have three versions of onDrawFrame, all dead simple. One is empty. One contains only glClear. One contains just enough state to only draw a fullscreen quad. Trace times before, and after. There is no view other than my GLSurfaceView in my program. I can't explain the times I get.In all cases, the onDrawFrame function itself always finishes under 2ms. But very often, onDrawFrame does not get called again before 30~40ms, dropping my frame rate all the way to 30fps or less. I get around 50fps with an empty onDrawFrame, 45 with glClear and 35 with a quad.
The same code runs at 60 fps on the HTC Magic, on the Samsung Galaxy S, on the Sharp ISO1. Sony Experia X10 caps at a solid 30fps because of its screen. I have been doing much more complicated scenes at a solid 60fps on the HTC Magic which is very underpowered compared to the Desire. I don't have a Nexus One in handy to test. Sure, I except buffer swapping to block for a couple milliseconds. But it just jumps over frames all the time.
Trying to find out what the phone is doing outside of the onDrawFrame handler, I tried to use Debug.startMethodTracing. There is no way I can get the trace to reflect the actual time the phone spends out of the loop. At the end of onDrawFrame, I use startMethodTracing then save the current time (SystemClock.uptimeMillis) in a variable. At the start of the next one I Log.e the time difference since the function last exited, and stopMethodTracing. This will get called over and over so I arrange for stopping once I get a trace for an iteration with a 40+ ms pause. The time scale on the resulting trace is under 2ms time, as if the system was spending 38ms outside of my program, I tried a lot of things. Enumerating EGL configs and try them all one after the other. Just to see if it changed anything, I switched to a render when dirty scheme requesting a redraw at each frame. To no avail. Whatever I do, the expected gap of 14~16ms to swap buffers will take 30+ms around half the time, and no matter what I do it seems like the device is waiting for two screen refreshes. ps on the device shows my application at around 10% cPU, and System_server at 35%. Of course I also tried the obvious, killing other processes, rebooting the device... I always get the same exact result.
I have a function that needs a Surface object to work. I'd like to be able to call that function from a background Service without starting a foreground Activity. Every Surface source in the API that I can see, though, requires a View that's laid out before the Surface becomes available. Are there other ways to create a Surface that I am missing, and can you point me to them?
View 5 Replies View RelatedI have an Activity that was created based on the TriangleRenderer example. It works flawlessly as a standalone project, but when I use it as the tab of a tabhost there is a problem. At startup the whole activity is just black - I can get touch events and do everything else but it doesnt show anything. When I change the orientation (and therefore recreate the activity) it all works well. Maybe the problem comes from the View focus. My SurfaceView is not focused when created inside of the tabhost. I tried to fiddle around with the methods available in my onCreate() and onPostCreate(), but couldnt find a way to get the SurfaceView focused. The following sourcecode blocks in the guardedRun() method because needToWait() is true because !mHasFocus is true. If I exclude the ! mHasFocus, it goes on but shows a black View anyways. Do you have any idea why it does work after orientation change, but not at the first startup? The Activity looks quite simple.

View 3 Replies View RelatedI'm trying to use OpenGL on Android using C. I'm following this excellent tutorial, but I've hit a wall.
I'm using an ARM compiler (arm-none-linux-gnueabi-ld) on Linux Mint 7 (Ubuntu 9.04 branch).
I can copy the compiled binary to the Android emulator just fine, it runs. But when I try to make it myself, I get the following error:
CODE:..............
It complains it can't find "GLES_CM". I'm at a loss as to what that is and where I can find it. A Google search comes up empty. There is also no man page for arm-none-linux-gnueabi-ld and I can't figure out what the -l flag is or does.
is it possible somehow to bind to private system services? What I want to do is listen to the activitymanagerservice and be notified when other activites are started. I tried implementing the IActivityController.aidl from the Sourcecode. It has methods like activityStarting and activityResuming but this didn't really work. (I used the idea from here: http://blog.codetastrophe.com/2008/12/accessing-hidden-system-service... , problem is there is no proper private field one could use at least c.getDeclaredFields() doesn't return anything useful from the activity manager)
Any ideas how I can get notified of things going on in the Activity Manager without having to do a getRunningTasks all the time? Because this is the only workaround I came up with but it slows down the phone.

i get an error message like 09-30 20:08:24.733: ERROR/AndroidRuntime(949): Caused by: android.content.ReceiverCallNotAllowedException: IntentReceiver components are not allowed to bind to services 09-30 20:08:24.733: ERROR/AndroidRuntime(949): at android.app.ReceiverRestrictedContext.bindService (ApplicationContext.java:136) so i guess you can't bind to a service in an AppWidgetProvider - although you can start the service just fine?

View 3 Replies View RelatedTwo activities here, A and B. A is main, B is PreferenceActivity with two EditTextPreference.
I want to be able to access the preferences generated by B from activity A, and for that I need of course (I guess) getSharedPreferences on A. But in order to do that I need to supply the preference file for the activity that generated it. This is tedious (long names), erratic at best (depends on the activity that generated it), and finally it's a mess, because it's much better to keep everything under one xml file, with a name that is well known to all my activities. And besides, if I have 100 activities, how would I keep track of preference files anyway...
So the point is: how do I "bind" an EditTextPreference in a way that the changes are made to a given preference file, not the one automatically generated by Android?
I'm new to Android development and am working on a small test project. I have a service, which communicates with an SQLite3 database, and two activities. A main activity which fetches database information via the service and displays it and a second activity which allows me to add data to the database via the service.
Currently, I have a singleton class which implements the ServiceConnection interface and I'm binding this to the service in the the main activity using the bindService function. Because it's a singleton, I can then use this service connection in both the main activity and second activity to work with the database and it all seems to work quite well.
However, I'm all the time aware that the service connection is bound to the main activity and I'm wondering if this is the wrong/bad way to do it? Would I be best off having two service connections, one in each activity, and binding each to the service?
I have coded this service, that computes stuff and i want other applications to be able to bind this service, i.e. i want to enable other programmers to communicate with this service. problem is, this has to work without these other programmers to get access to the source code. just the (installed) apk with the remote service is given (and of course a detailed description of the service' interface)...problem is, eclipse keeps braggin' about that the packages of the service are not available in source code...
View 1 Replies View RelatedWhat I need is to perform some network operations in background inside a service. I want them to run in a service because, as pointed out in the "developing rest client application" talk from google io, I don't want to loose the result if the activity is brought in background. What sounds quite obvious is to use an Intent Service, and get the result as a broadcast. In this way I am sure the service will die and no consume any other resources when its done, but I need to convert the actions I want to perform to intents and back. Well, I was now wondering if it makes sense to bind to the service instead, at least for getting the result. And a more general question: is the bind mechanism suitable for one shot services, or it just make sense for persistent services? What happens if I call the startService method but the service is already active? Will it start another service, or will it call the onStartCommand of the same service? I am asking this because if I use "regular" non sticky service, it could happen that I need it to perform some action and I don't know if it is already active (and I don't want to have a queue of action waiting for onServiceConnected to be called.

I am working on a graphics application in Android. I have a question regarding MULTIPLE SURFACE VIEWS. Can I be rendering multiple surface views at the same time. Initially, when I had two surface views in the same activity, it didn't seem to work, as it used to show only one at any time. But, with one surface view attached to one activity, is there any way I can keep the background activity's Surface View alive so that both the surfaces get rendered together?
