I am having difficulties with the lifecycle of the opengl context. While rendering my scene and the user hits the back button, home button or another application opens in front of my application, my app is still running in the background.
So when my application comes to the foreground later on (user relaunches it or the app that was opened on top of it finishes), my application crashes and leaves me nothing but a GL stack trace which i can't properly decipher.
For rendering i use the GLSurfaceView and therefore delegate the onPause and onResume. The crash happens on the first call to glDrawElements(..).
I have tried to reload my resource (geometry/textures etc.) on onSurfaceChanged but with or without reloading... The problem persists.
This behavior can be observed on all AVD versions of the emulator as well as on the G1.
Here is the gl stacktrace i get.

I'm writing my opengl native game. Menu is using android api, game field using native lib ( c++ and opengl ). All in one activity ( different views ). If I press Back or Home button ( without overriting onKeyDown() ) all is fine: game just quit to desktop and when I again running, it saving its state. But I was needed to overrite Back and Menu button:
CODE:...............
Than I quit throught Home button and again run it. Sometimes all is fine, but sometimes I see only my menu, and black screen where the opengl must be. What's the problem? Also I was trying to overrite Home button, but seems it's impossible..
Once again I'm trying to get into openGL, but as usual I choke when passing around vertices/vertixes/whatever and every little detail can lead to disaster (wrong format, initialization not properly set up, where memory are saved, etc.).
My main goal is to use openGL for 2D graphics to speed up performance compared to regular cpu drawing.
Anyways, my openGL Renderer looks like this code...
With an IndexOutOfBoundsException, but I'm sure there are more problems with the code.
I'm trying to draw a very simple 2D triangle with opengl. but i have exception "illegal parameters"

I simply copied code from other examples. and it simply doesn't work.
I'm pretty sure the mVertexBuffer is successfully initialized. because i can see the size of the buffer is 48 right before the execution of the problematic line with the debugger. and this size is correct.
However it just doesn't work.
I initialized the buffer this way:

We are facing 2 issues on the nexus 1 using opengl( under NDK ):
1)glNormalPointer(GL_BYTE, x , y);does no work, there no lighting done on any model using normals stored using byte, the same code is working properly on a motorola droid/milestone.
2)Changine Lighting states are very slow and freeze the display frame for 1 sec on the Nexus 1, we are using dynamic light ON/OFF and i am under the impression that is because of the emulation of the opengl 1.x pipeline under a 2.0 pipeline -> some hidden upload of shaders of some sort in the drivers, but this is to a point that there is no way to use realtime lighting on our game for the nexus 1 so somebody has to look into this issue.
My Nexus 4 (purchased directly from Google) automatically downloaded the latest update today. I installed it, and everything crashed. My phone is now caught in a continual re-boot loop. It gets as far as the little dead robot, and then stops with the message "No command", holds for a bit, and then starts the reboot again. Has been doing this for the last half hour or so.
How can I break the cycle, or reset, or something? Anything?
BBC iPlayer switches my tablet off if I try to resume playing a downloaded programme after I've switched tablet off. I emailed iplayer support who claimed they had not come across this problem. I think it might have been since 4.4.2 was installed.
View 1 Replies View RelatedTo put it short: Dolphin Browser started force closing randomly a few days ago. I couldn't get rid of the problem and tested pretty much every browser available for the Android platform. Opera, Firefox, Boat, xScope, Maxthon and so on, they ALL crash. I don't really like Google Chrome, due to its lack of options (no fullscreen etc.)....
Here is what I did:
- uninstalled and reinstalled Dolphin
- rebooted the tablet
- deleted the app cache (also via "wipe cache partition")
- disabled Google Admob
- executed a full factory reset, installed Dolphin first, still crashing
The problem itself is well documented and affects many OS versions, even more devices and every browser. The only workaround is to disable JavaScript, which of course renders many web pages unusable.
Coming from a Blackberry Playbook with its own fair share of browser related crashes, I'm now utterly frustrated with the situation. The first three weeks with my new Nexus 7 felt absolutely perfect.

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?

View 2 Replies View RelatedI'm using the following to draw rounded-corner rectangles in my Android application and it seems to be working alright but with one minor problem:
CODE:.......
(Adding labels to the rectF's defined above follows) ...
The strange thing is that the two ends of the rectangle aren't rounded over the same. The left-size quarter circles are noticeably smaller than the ones on the right.
Anybody experienced anything similar? It's weird enough that I might change my mind about the round corners if I can't do anything about it.... And if I knew how to do a screen capture from my Android, I would.
The rectangles in question are 78 pixels wide and 48 tall, if that helps (and since ykatchou may be onto something).
With the XML layout shown below, I have some views wrapped in a GestureOverlayView. As shown below, my first row is blended with the second row, as-if the first row is transposed right on top of the second. Now when I take the GestureOverlayView out of the code and leave everything else as-is, my table looks fine - the rows are separate and not on top of each other..........

View 1 Replies View RelatedI have a simple app that just initiates a wifi scan every two seconds and then logs the results. I am observing some strange behaviour, and was wondering if anyone could shed some light. When I start scanning, if the phone (Nexus One running latest Froyo OTA release) is just sitting on my desk (screen on or off, it doesn't matter), I receive the wifi scan results about 800ms after initiating the scan, fairly consistently. At most, it takes a second and a half to receive the results. However, if I get up and start to walk around the building that I'm in, the time between initiating the scan and receiving the result begins to vary greatly. What is interesting is that I start to see a pattern where it will take about 40 seconds to receive results, then I will get three or four results two seconds apart, then it takes 40 seconds to receive the next set of results, then I get three or four results two seconds apart, etc.
I've tried obtaining a wifilock, both the FULL and SCAN ones, and that doesn't help. Same with a partial wakelock. I've also tried setting up a thread that pings the supplicant every second and reports when it is unreachable, and it appears to always be responsive (ie., I never see the report). I thought that maybe the problem was that I am unable to receive the result of scans when I am switching between base stations (which might happen when I move around), but if I manually switch between two different networks, it does not cause a delay in my scans (ie., I can still get the results with only a one second delay while it's associating with the new network). Anyway, for my application, it would be incredibly useful to get wifi results at a fairly consistent rate, and so I was hoping that someone on this list might have some suggestions as to how I can achieve this.
A customer just notified me that she's experiencing the infamous "app not responding / wait, force close" message during a specific operation. By just waiting enough, the app resumes ok. Now, that specific operation is indeed long and in fact it has been programmed in a background thread, with a progress dialog signaling the wait. I can't reproduce the problem on my development phone - I suppose because it's perhaps faster than the phone of the user. But I can't reproduce the problem either with the emulator, which I suppose is slow enough. Generally speaking, I think I could be able to solve this specific problem with the customer giving me the proper feedback. It's the general issue that hassles me. This part of the application is very good covered by tests at different levels, including automated black-box tests with Robotium that drive the UI as the user would do, and even in "stress mode" (repeating the test multiple times). So I supposed to be very safe in that area and I'm disappointed to discover that it was a false sense of safety. What am I possibly missing? Also, is it possible / does make sense to "slow down" a phone during tests? I was thinking of a service running in background just consuming some CPU cycles to make the phone less responsive.

I need to retrieve the orientation of my phone. At the moment i wrote this :
CODE:................
This code allows me to get the orientation of the phone if i leave the phone on a flat surface and i rotate it over the surface.
What i did not understand is why if i move the phone upwards the value of this.actual_orientation[0] ,which is the rotation on the zed axis as described [here][1], the value increases although there was no rotation.
Did someone know what happens?
Another strange thing..
I tried my application in the office at work and it had the strange behaviour i described before..
I tried in the same office(same situation) a compass app that i took from the market and it has the same behaviour of mine..when i moved the phone upwards the value changed consistently..
I tried in the same office(same situation) the i-phone compass and it didn't have that strange behaviour!
Then when i arrived at home i tried both, my application and the compass app of my android phone, and they worked!even if i move upwards the phone the value are stable...
Last night I downloaded antivirus free by droidSecurity inc.I ran a scan and it said I had something suspicious but would not allow me to view any details. Eh lame, I removed the app and jumped into bed.Today I was out driving around and got a warning my internal Phone memory was low. I took a look and it said 150 MB free.so I rebooted the phone and maybe I was being dumb because I thought you could cancel the SIM password and use the device as a PDA with no access to make phone calls.Anyhow I restored my clockwork recovery nandroid backup from a couple of days ago and now things seem better. Phone has 0.9 GB free.Are there any good applications to help manage the available memory on the phone?
View 4 Replies View RelatedI have a strange issue. I am using KSOAP2 to create a soap request to a .net webservice. I do this in a few other places and everything works fine. The webservice basically queries a data base and takes the values from the data reader and creates a string. This string is then returned. When I run the webservice on my local machine(Without using android) it works fine. When I run it from the webserver (still not android) it works fine. When I call it from my phone however the line: String hazards = (String)envelope.getResponse().toString () ; //Get response from .net Web service Simply is filled with anyType{}. Now if I go to the webservice and I manually type in the contents from the database to represent what the string concatenation should be it works perfectly. The line: String hazards = (String)envelope.getResponse().toString(); //Get response from .net Web service Now returns the string value i need. Does anyone have any idea why this is happening or know a better place to ask this question?
View 4 Replies View RelatedI'm trying to get my head around how the vram is used in opengl, specifically when and how to clean it up. The Story So Far. I have a GLSurfaceView into which I set a Renderer implementation (called OpenGLRenderThread). This view is created (manually, by calling "new") in the main Activity of the app. When the onSurfaceCreated method of the OpenGLRenderThread is called, I load a bunch of textures in a fairly standard way: the app runs fine, however when I try to clean up these textures at the end of the "level" (the app is a game. I do the following: On the emulator it works fine, but on the device (HTC Desire, 2.1) I get a GL Error 5572216 I have no idea what this error code is as I can't seem to find any reference to it. I understand that the VRAM references are bound to the thread that created them. Hence they can only be destroyed by the same thread. In my case, this thread is the OpenGLRenderThread (Renderer) during the onSurfaceCreated call.Unfortunately the Renderer interface does not expose an "onSurfaceLost" method, so I created my own. When the Level is complete, my main activity queues a request on the OpenGLRenderThread using the following call to the GLSurfaceView: According to javadoc for queueEvent: "Queue a runnable to be run on the GL rendering thread" Ok fine, so this should mean that the OpenGLRenderThread is performing the call to onSurfaceLost. This method is the one that then calls glDeleteTextures, and produces the error. what am I doing wrong here? I am not destroying the OpenGLRenderThread or the GLSurfaceView at any point (other than game exit) so I'm worried that if I don't explicitly delete the textures my vram will eventually fill up, or worse get into a corrupt state. The only other thing that may be relevant is the use of a ViewFlipper. Because I want to load each level asynchronously I am using a ViewFlipper in the main activity to flip to a loading screen while all the level resources are rebuilt. Hence when the call to glDeleteTextures is made, the GLSurfaceView is not actually visible not sure if this is meaningful or not.
