Looking the doc with class SurfaceHolder is possible set the kind of surface format. I need to show images YCbCr_420_SP format. If I set YCbCr_420_SP format is not clear after how I can set the data. With Canvas object I can draw only bitmap format and not YCbCr_420_SP. Then my question is : can I draw directly on surface using YCbCr_420_SP data ? how ?

View 4 Replies View RelatedI have created a listview with simple list items.When i click on any of the list item a new activity is launched and therefore a new screen opens. But now i want that when i click on the list item i should have a kind of popup which has three options and depending on the option i click a new activity should be launched. Therefore in place of one activity i want an option of choosing one of the three activities depending upon what i chose in the pop up box. I should also have the flexibilty to design the pop up box the way i want.
View 3 Replies View RelatedWhen I get my activity chooser for my ACTION_GET_CONTENT Intent there is applications I don't want to be there, like the ones who will first create content and then pass the URI to me, like the Voice Recorder. When you use Gmail and try to attach a file you will only see the applications/activities that picks data from your SDCard like Gallery, and in my case Astro (file manager application).
So my question is, what kind of Intent does Gmail use for their Attach? Here is my code, something must be missing since I get applications like Voice Recorder and so on.
Intent action = new Intent(Intent.ACTION_GET_CONTENT);
action = action.setType("*/*").addCategory(Intent.CATEGORY_OPENABLE);
startActivityForResult(Intent.createChooser(action, "Upload file from..."), 1);

View 3 Replies View Relatedits not that bad but in all honesty, I found it to be pretty bland and boring (almost ugly). It also lacks many nice features found on other phones with manufactuer overlays, (This is probably the biggest reason why they put those overlays on top of stock android). Obviously the best thing about it of course is the quicker updates (in most cases). But other than that, my experience with stock was not too fun compared to using now Launcher Pro overtop of just plain stock and even now over TW (I know, i know, people hate TW).
Just had to put this out there. (At work TBC)

recently bought a car in CHINA and it came with a Android powered dvd/navigation/fm/player/etc. I have it already connected to a Mobile WiFi over the China Mobile via a USB WiFi Dongle and downloaded some apps. Some apps I use are blocked in china (TuneIn Radio, Pandora, etc), and i'm looking for a way to have a VPN on it.
The thing is that the manufacturer of the device removed the VPN network settings, so I can't connect (or it is absent on the Android 2.3.4 ). is there a way to install some kind of VPN Client on this android? I already have a paid VPN Account and use on my apple devices.
I am planning to write a video player application and I am planning to use the gstreamer on the native side. I am trying to use the SurfaceFlinger for the rendering part. For this I have written a test program to experiment on the rendering part. I am using the surface flinger wrapper from the project
http://gitorious.org/rowboat/external-gst-plugins-android
But the following ERROR occurs when we try to run the .apk.
CODE:.......
The I changed the permission for "android.permission.ACCESS_SURFACE_FLINGER" in frameworks/base/core/ res/AndroidManifest.xml to "dangerous" and recompiled. But got the same error.
Then I commented out the "checkCallingPermission" method in IServiceManager.cpp and recompiled. Then also i got the same error.
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?

How do I do the mapping? I know how to map to flat surface. I'm wondering if the normals can be used to help but I've never done this before and when I search Google I don't have any luck. I'm planning on doing this all programmatically and not using Blender or Maya if that makes any difference.

I've created game, everything works fine on all previous android versions except current cupcake 1.5. It works even on cupcake pre release.I'm using exact the same build.xml, sources and resources. The problem is that surfaceCreated is not called : SurfaceHolder mSurfaceHolder = getHolder(); mSurfaceHolder. addCall back(this); setFocusable(true); WaitForScreen(); - here I untill surfaceCreated change variable that it's ready,but it's never called. I just can explain that I'm running SurfaceView activity after stopping regular View activity (for the game menu - it was easier to create it). Please help me if you can figure out something. I'm just a developer not a Android engine tester. If they are putting such stuff to the market they should test it a little bit (not talking about discovered VM crashes instead of exceptions).

As in, Say I have a kind of taskbar/toolbar which is part of all views. Is there any way in which Activities from one "Frame" can switch but activity in other frame remains stable?
I've read several example programs and tutorials to try and solve my problem but they all seem to go the same way. I've used a couple Activities and xml documents to create a menu that loads when my game starts.When the user clicks the "Start The Game" button, it loads a new Activity that sets the view with my game thread and all of the game properties.I know this activity works because I've run it alone as its own project, but every way I've tried to start it after the Menu,I get a nullPointerException and it force closes.I read the SurfaceViewOverlay tutorial and attempted to use that implementation, but I'm using a SurfaceView, not a GLSurfaceView.I'm debating rewriting my entire program to use OpenGL but I figured I would see if anyone else knows what I'm doing wrong here.If you need the code snippets I can paste some here, but it's not really the specific code that's wrong.

View 2 Replies View RelatedI'm trying to render a 640x480 RGB565 image using OpenGL ES on Android using GLSurfaceView and Native C code.

But now, in the "drawFrame" call, when I do glDrawTexiOES to resnder the texture, I'm getting the following error on the Logs: drawtex.c:89: DrawTexture: No textures enabled I'm already doing glEnable(GL_TEXTURE_2D), is there anything else I should do? Is there a complete example showing GLSurfaceView with native code using textures?
View 4 Replies View RelatedI have a simple program that draws the preview of the Camera into a SurfaceView. What I'm trying to do is using the onPreviewFrame method, which is invoked each time a new frame is drawn into the SurfaceView, in order to execute the invalidate method which is supposed to invoke the onDraw method. In fact, the onDraw method is being invoked, but nothing there is being printed (I guess the camera preview is overwriting the text I'm trying to draw).
This is a simplify version of the SurfaceView subclass I have:
public class Superficie extends SurfaceView implements SurfaceHolder.Callback {
SurfaceHolder mHolder; public Camera camera; Superficie(Context context) { super(context);
mHolder = getHolder(); mHolder.addCallback(this); mHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
} public void surfaceCreated(final SurfaceHolder holder) { camera = Camera.open();
try { camera.setPreviewDisplay(holder); camera.setPreviewCallback(new PreviewCallback() {
public void onPreviewFrame(byte[] data, Camera arg1) { invalidar();
} } ); } catch (IOException e) {} } public void invalidar(){ invalidate(); }
public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) {
Camera.Parameters parameters = camera.getParameters(); parameters.setPreviewSize(w, h);
camera.setParameters(parameters); camera.startPreview(); }
@Override public void draw(Canvas canvas) { super.draw(canvas);
// nothing gets drawn :( Paint p = new Paint(Color.RED);
canvas.drawText("PREVIEW", canvas.getWidth() / 2, canvas.getHeight() / 2, p);
} }
I have openGL layered on top of camera view by using the 'workaround' specified at-http://groups.google.com/group/android-beginners/browse_thread/thread... and it works great.
However, has been mentioned before that surfaceviews were not designed to be layered ontop of each other- [url]
As you can notice in the code snippet thats mentioned in the first thread, to get openGL working on top of camera we are first setting the contentView to be the openGL view and then adding the camera (on top of it) instead of the other way around as one would expect it. I am assuming there's something strange going on in here as it has also been mentioned that Z-order is not supported on surface views- [url]
Now my question is will all devices have this behavior? Can I use this behavior in my app to get openGL layered on top of camera preview? Please answer this query, its so cool to have openGL over the camera preview! It opens up for some amazing stuff!
I am using android.hardware.Camera to get a preview and display it on a custom SurfaceView that implements SurfaceHolder.Callback.
I am trying to zoom in to the camera preview surface by a specified scale (not using the camera's digital zoom) but I can't seem to find a correct way to do it. I also need to be able to zoom out and scale down the preview.
I was hoping to be able to do this using a ScaleAnimation but it doesn't seem to work on SurfaceView, nor the FrameLayout containing the SurfaceView.
I also tried setting the size of the SurfaceView using setLayoutParams but that doesn't seem to work too well on various hardware and it would be tough to animate smoothly.
How to achieve this effect? Right now I am starting to think I might have to implement this using GLSurfaceView but I'm very unsure.
