The last thing to do is to set the path for your NDK in the settings menu: Window Preferences Android NDK Now you have the NDK integrated with your Eclipse IDE.

[android-developers] Re: Reading precomputed vertex arrays in application?
I am also considering going the C route - although even there one must beware of Endian issues in future products. However, I started the thread because I was hoping to do it in Java. Endian issues could be handled by just having to sets of data, and reading the right one. However, its unclear to me the relationship between native C arrays (which underlies the glSurfaceView API) and the Java code needed to fill them. I currently use several lines of java to take a byte array and make it into an Int array, which is rather mysterious to me. There is a method to just wrap an array, but its never worked for me. Can anyone shed clarity on this?

You can simple insert them into a HashMap and serialize the whole thing. It deserializes surprisingly fast, especially if all you're storing are ints or floats for the data. If your data is less structured or more linear, you could certainly write up something to generate a java source file with the data in it like you said. It's probably going to load nearly the fastest, though it requires a little more programming than serialization does.

I use a script that takes a bunch of individual graphics files and puts them into a couple atlas textures, then pre-generates the texture coordinates for the two triangles needed to draw each graphic. So each pre-generated atlas texture has a pre-generated Java file with an array of all the useful texture coordinate sets for it, and constants for the offset into the array to use to get them for a particular graphic.

[android-developers] Re: Emulator bug drawing lines on GLSurfaceView
IV - thanks for your response. You are correct that if LINE_SMOOTH is disabled, the bug does not show up. An important point is the all the lines in this example have the same slope (0) and yet their width varies - with the position of the X coordinates. That is a very odd result, that I don't think can be explained as an artifact of emulation (an in a philosophical sense, if the emulator can produce a display that far off, it just isn't emulating very well in any case) However, I tried your suggestion - I multiplied the second Y coordinate by a variable (tried 1.1 and 1.5). In both cases, the slope is visibly not 0, and the width of the overly wide lines is narrower, but still WAY too wide. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Emulator bug drawing lines on GLSurfaceView
The Emulator draws line widths VERY incorrectly in OpenGL (GLSurfaceView). See http://www.flickr.com/photos/53002...@n03 for a comparison of the lines drawn correctly (in JOGL) and incorrectly in the emulator. The code also draws correctly on a real device (G1) - looks just like the JOGL screen shot. I believe this is a bug. However, I'm not an OpenGL GURU. Hence I have posted a concise version of the code to demonstrate this problem at at http://gist.github.com/523955 and http://gist.github.com/523961. I hope I am proven wrong about a bug in the emulator, and can find a way to use the emulator for what I want to do. Specifically, line widths vary based on the end point locations of lines, under the following conditions (and maybe others): -ortho projection -line smoothing enabled Note: I started this thread as a continuation of thread http://groups.google.com/group/android-developers/browse_thread/thread/9cd619ea5f2fcc99 because I think it is of general interest and worth a new start. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Yeah, I have since my last post. If I use a very wide line (, it does
show up on the emulator, as a wide (not 1 px) line. On the phone, it
still shows up as a 1px wide line. Go figure.
There is something else fishy on the emulator that hints at an issue

[android-developers] Re: How to test OpenGL?
Robert Green, thanks again for your informative answer. I added the MODELVIEW mode right after setting the viewport, and did a loadIdentity after that. No change, but I agree its the correct thing to do. Still zero lines visible on the emulator (even when I scale up its display). Looks fine on the G1. Off to read the manuals again ;-( Per your question: gl.glScalef(1, _hgt2width, 1); float lscale = .002f*MyApp._curScale; It could be that I just don't understand what this is supposed to do but magic multipliers like .002 never look good to me when you're having issues with drawing precision. I am drawing in a geographical coordinate space, not pixel space. So the scaling is used to transform from that space to the viewing space. In my geographical space, my coordinates are in (projected) lat/long specified with higher precision than even float can deal with (which, fortunately, isn't a problem with this app). My test case uses simple coordinates, but I left in the same scaling as in the real app. // ditch the fixed point (it's only faster on first-gen devices and only in certain cases) For now, I'll keep it because a bunch of code is in it, and I am testing on a first gen device. // now if you want a line 1px wide on the 10th line, draw a line with x on 9.5f I just want my lines to show up, and my reading of the openGl documents indicates that they should, if drawn with a line width of 1, no matter where I put them. Of course, offsetting them from pixel edges would be a good idea, except I am not drawing in pixel coordinate space. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: How to test OpenGL?
It is entirely possible that I am doing something confused (not being that much of an OGL person), but even then, I would expect to see the same results on the emulator and the G1. In answer to another question, the demos work fine on the emulator. Is it possible that disappearing lines are caused by the emulator pixels not matching exactly the Windows pixels to which they are ultimately rendered? The varying width lines didn't appear until I used extremely large (but within the FP range) coordinates on a few lines. I'll post the code when I get home and have access to it. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Source code is below.
Robert Green provides some helpful information, for which I am
thankful.
However, I am not clear on two of the points.
I currently have the situation where no lines at all show on the
emulator (the background color does) and things work perfectly on the
G1.

2) You draw the lines centered on their pixel, so they look a half
pixel off.

make the line with 1.0f and have y be 0.5f (because it will draw from

I am drawing in fixed point projection(?) space, so the relationship
of the lines to pixels is not clear. Also, I don't want to have to
redraw the lines when the scale changes - I want to be able to zoom
and pan easily. Is there a way to achieve that and have the lines
show?
3) Make sure you don't have any z-fighting. Drawing 2 things on the
exact same plane with depth-test turned on causes bad results on many
opengl implementations.
Depth test turned off. I'm doing 2D only, so I think I'm clear there.
Again, thanks for the help.

[android-developers] How to test OpenGL?
After a frustrating day of having the Emulator render lines strangely, and then discovering that my G1 renders them exactly as I expect, I am left to wonder how to test OpenGL (using GLSurfaceView). Is the emulator sufficient to test code for correctness? I ask because I experienced the following on the emulator, but not on the G1, all using Ortho projection. 1) Line width depending on length! I drew a series of lines, most fairly short but several with endpoints close to the edge of the fixed- point number range. The long lines were rendered as wide. The short lines were rendered as 1 pixel wide. 2) Lines exploding to fill the whole screen when not appropriate to the scale (double the scale, line goes from 1/10th screen width to filling screen (or more). 3) Lines not appearing at all if horizontal. Is the emulator a correct openGL implementation? If I see problems on the emulator, am I likely to see them on some hardware platforms? Can I use my G1 as a reference platform? Or do I need a whole slew of phones to verify that an openGl app (scientific graphics, not animated) works across all platforms? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] OpenGL missing pixels?
I am drawing lines in OpenGL on an app that will zoom way in and out on the surface. I would like the lines to always be visible. Currently, when the line widths are small, at certain angles, the lines don't render. Specifically, I have a case where diagonal lines show but a horizontal one does not. The line width is way less than a pixel, but there is nothing else in the area of the pixels that are not being colored. Is there a way to force sub-pixel elements to cause the enclosing pixel (otherwise empty - nothing drawn there) to render the color of the sub-pixel element? What is the rendering algorithm that causes the sub-pixel line to render when at an angle but not when horizontal (and hence, at the same position in every pixel)? Can I change it?

[android-developers] NDK OpenGL - Mixing Java and Native (C) calls to OpenGL API?
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? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Can I use OpenGL to make Bitmap without GLSurfaceView
I would like to be able to use OpenGL in the Android to render into a bitmap (or any other sort of buffer I can turn into one), without actually displaying a GLSurfaceView. The purpose is to dynamically create very complex images using OpenGL, and then drawing those images on the canvas of a MapView. I have tried overlaying a translucent GLSurfaceView over a MapView, my preferred approach, but it has some problems: 1) I have complex menus I need to display from either the MapView or the GLSurfaceView. I have been doing this using a ListView with its own activity. Unfortunately, that activity pushes the MapView down the stack. The result is a bit of flickering when the ListView activity finishes, popping the MapView back to the top. Even worse, if I use the ListView to overlay the GLSurfaceView (giving it the same complex menu capabilities), when it finishes, the GLSurfaceView reappears but the MapView doesn't display. 2)As soon as the GLSurfaceView is created, the MapView stops fetching and rendering tiles. There seems to be no way to know when the MapView is complete, so I have to delay an arbitrary interval before creating the surfaceview. 3) When the GLSurfaceView is present, the MapView's built-in user interface functions are obscured. Anyone know if there is a way around any of these problems? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Google Map drawing stops when GLSurfaceVIew overlay started
I have an application that uses a the Google Maps API to create a map in a MapView. It then uses an intent to start an activity which uses a transparent GLSurfaceView as its content - to overlay OGL content on the map. When the GLSurfaceView activity is started, the map stops fetching and rendering tiles. If I pause a while before starting the surface view, everything works fine - the map renders, and the view draws over the map appropriately (with the map showing through transparent parts). That, however, is not a very satisfactory solution. I can't tell when the map is fully rendered, and also, I would rather have the map loading tiles while the OGL work is in process. Is there any way to make this work other than the kludge of just waiting a couple of seconds before firing off the activity for the GLSurfaceView? Is there a different way to use a GLSurfaceView over a MapView than with two activities?

[android-developers] Re: How do I overlaying transparent gifs
Answering my own question:
If using the draw method on an ImageView, the transparent color is
treated as transparent. No extra effort is required. The Z-order is in
order of the draw operations (not surprising).
Example code:
if ( bm1 != null ) {
canvas.drawBitmap(bm1, (Rect)null, r, new Paint());
}
if ( bm2 != null ) {
canvas.drawBitmap(bm2, (Rect)null, r, new Paint());
}
}

I created a normal Android project in the Eclipse IDE, added the GLSurfaceViewActivity class and related from the sample directory, set the activity to GLSurfaceViewActivity, and ran it on the emulator. It worked. Then I hit the home button, launched another app, hit home again, and launched my test app again. This time, I got a blank screen (with now exceptions thrown in logcat);. Any ideas? I was motivated to try this example because if have been having the same trouble with my own app - discussed iathttp://groups.google.com/group/android-developers/browse_thread/thread/b1b97aa8e18e6b04 . My application has Log.d calls that show the following sequence: onCreate onStart onResume ...working app with rendering on the GLSurface... onStop onCreate onStart onResume ...everything works but the GLSurfaceView rendering. (see related discussion) (onStop-onCreate-onStart-onResume). That app is careful to call the notification methods on the surface when when system state change callbacks in the view are called. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

More information: It works if it is the ONLY view on the page, as done by _surfaceView = new GLSurfaceView(this); setContentView(_surfaceView); However, if I make it part of the app framework, it fails as described above in this discussion: setContentView(R.layout.main); _surfaceView = (GLSurfaceView)this.findViewById(R.id.SurfaceView); See below for main.xml Odd, eh?

[android-developers] Trouble with GLSurfaceView
I've been messing around with GLSurfaceView, first with just my own code, and then with the demo framework from Pro Android. In both cases, the view stops working after the application has been paused (say, by bringing up the home screen, and then selecting the application and running it again). I am calling the onPause and onResume methods on the GLSurface view object, but it still doesn't restart. The rest of the app recovers - the buttons are visible and they work.

That's exactly what I want to be able to do, and the reason I started this thread. Thanks for the answer. I just tried android:screenOrientation=portrait and it now completely ignores orientation changes, which is good! It still cycles the activity when the keyboard is opened/shut.

This is always done I downloaded an application which never dims/blurs, so they must have figured out how. It is called Bubble and is a simple level. It has three orientations (horizontal level, vertical level, surface circular leel) that it switches between depending on orientation. But the switch is instantaneous and it never burs.

This one covers what you need: http://androidguys.com/?p=2723 In your case, you would detect the rotation and change how you draw on your canvas to match. Thanks. I tried that and it still doesn't do the trick. I have a simple layout - a couple of buttons in a listview, a couple of text fields in a listview, and a custom SurfaceView. The problem is that when I rotate the device (changing orientation), even with the hacks ( and logging to verify that the onConfigurationChange method of my activity is being called), there is still half a second where the screen goes grayish and my SurfaceView is inaccessible to draw on. Oddly, popping the keyboard in and out also results in an orientation change, but nothing goes gray. In both cases, based on the log, my methods get called in the same order.and the time from surface destroyed to surface created is virtually identical at about 450 msec.

[android-developers] SurfaceView behavior - what gives?
I wrote a little test program that has a custom SurfaceView class and some buttons to let me cause various operations on them (draw bitmap over all of it - white or black, draw a circle on it, draw blue bitmap and circle). In each case, the drawing is done on a canvas obtained with getHolder.lockCanvas(). If I draw the white background in one op, then draw the red circle, the background vanishes. If I draw the red circle again, the white background re-appears behind it. Other operations have similar results - it's as if there is a toggle on the background pixels (those untouched by the circle drawing) - draw the circle once - get one background, draw it again, get another. Obviously I don't understand the semantics of SurfaceView. Any pointers? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Keeping graphics running through orientation change
How does one create a graphics canvas that is visible by the user through orientation (port-land-port) changes? If one defines layout land and port, there is a noticeable pause during the switch. Yet, I downloaded a bubble level application that never pauses as orientation changes - even when it switches from a circular level (gravity vector through back of device) to a flat level (gravity vector through side or bottom edge).

[android-developers] Apparent Eclipse/SDK error
I created an android project in eclipse that had a custom MySurfaceView object that was a subclass of SurfaceView and was declared in the layout. I refactored this project several times. When I tried to run it, it blew up immediately. I used adb.exe logcat to look at the logs and it was having trouble “inflating” MySurfaceView - couldn’t find the class. After wasting lots of time, I suspected that the project wasn’t being built correctly. I created a new ASurfaceView class and put all the MySurfaceView stuff in it so it was identical except for the name. I then deleted MySurfaceView.java. I changed the layout xml to refer to the new ASurfaceView.
