[android-developers] Focus problem with Option menu
Hi,
I've a problem with Option menu and focus.
I've a simple View in which I've some data come from remote service. I've
to display an icon of the option menu only sometimes when remote object has
some characteristics.
So I do this:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
return true;
}
@Overridepublic boolean onPrepareOptionsMenu(Menu menu) {
if (corsa != null corsa.getDataPartenzaEffettiva() == null) {
menu.clear();
getMenuInflater().inflate(R.menu.dettaglio_corsa, menu);
}
return true;
}
The first time I create an empty menu and then when I receive remote data
(asyncCall) I call invalidateOptionsMenu(); so I display the option menu
icon. All works fine but in this view I open programatically the keyboard:
InputMethodManager inputMethodManager = (InputMethodManager)
getSystemService(Context.INPUT_METHOD_SERVICE);
if (inputMethodManager != null) {
inputMethodManager.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
}
the problem is that every time I press a key on the keyboard the icon of
Option menu focus, and when I press enter the option menu is clickked. I
don't want this, why the option menu is focused every time I press a key?
Thanks

[android-developers] Need to show a dialog on top of all other Apps for a custom hardware.
Hi, I need to show a dialog (more like a horizontal bar) on press of a custom Key (on my custom device powered by Android). This dialog should appear on top of any other application(say A) that might be running when the Key is pressed. The app A should keep on running and its UI should be visibile (i.e the app A: should not go to onPause()). It should work something similar to SystemUI's volume change dialog when Volume Hard Keys are pressed. I want to make minimum changes in framework. My understanding is that I need to make changes in PhoneWindowManager.java to handle the press of custom Key, which will then call my app residing in application layer, which will just inflate the dialog. Would this work? If so, is there a better way to implement it? If not, how can I implement this? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] 3D model importer / engine for Android / Android NDK for use with Vuforia - what do you use?
Hi, I'm scouting for a 3D model importer library. I'd like it to have support for COLLADA and FBX format. Our iOS team is using NinevehGL engine: http://nineveh.gl/ which is just perfect... but for iOS only. Do you know of something similar for Android? I want to add a quote from *Diney Bomfim*, the author of NinevehGL: If you choose a 3D engine, like PowerVR, SIO2, Oolong, UDK, Ogre and many others, you’ll be stuck inside their APIs and their implementation of OpenGL. If you choose a third party API just to load a 3D file, you will need to integrate the third party class to your own implementation of OpenGL. Another choice is to search a plugin to your 3D software to export your objects as a .h file. The .h is just a header file containing your 3D objects in the OpenGL array format. Unfortunately, until today I just saw 2 plugins to do this: One to Blender made with Phyton and another made with Pearl and both was horribles. I never seen plugins to Maya, 3DS Max, Cinema 4D, LightWave, XSI, ZBrush or Modo. *took from http://db-in.com/blog/2011/02/all-about-opengl-es-2-x-part-23/ * Which I think is true for Android too. iOS developers has the option to solve those issues by using NinevehGL. Do we have some option like that for Android? *My specific need* is a library that interact well with Vuforia - http://www.qualcomm.com/solutions/augmented-reality which is a library for Augmented reality using NDK and a C++ library. Vuforia examples show, via OpenGL, the camera and overlay upon it a very simple 3D model defined in .h files. I need something to keep all that and just change the model / underling database of features detections. My scouting results until now: - JOGL - https://jogamp.org/jogl/www/ - this is a Java library that just act as a bind to OpenGL®, OpenCL™, OpenAL and OpenMAX APIs inside Java - to my needs it's not that much of an help, I only need OpenGL to show a 3D model and this library doesn't provide a way to import one - nor has anything more then what I can already use with NDK - Min3D - http://code.google.com/p/min3d/ - this is a Java library to import OBJ, 3DS and D2D models, many guide talks about it but it seems pretty dead project, no commit since 2011 and it use a Scene object which somewhat collide with the way Vuforia use OpenGL - JPCT-AE http://www.jpct.net/jpct-ae/index.html - this is another java library which expose a very simple 3d engine and import for 3DS, OBJ, MD2, ASC which is horribly written (IMHO) for Android - Assimp (Open Asset Import Library) - http://assimp.sourceforge.net/ - this is a C/C++ library for importing almost any 3D model around (including COLLADA and FBX), it just provide methods to import the models and should work very well - but that's no version for Android even if some folks actually managed to use it with Android ( http://jazzyjester.wordpress.com/2013/02/02/test/) - Unity3D - http://unity3d.com/ - Very complete 3D crossplatform framework, in my company we already use it, too bad you can't integrate it very nicely with a native application that just use 3D with Vuforia in a fragment. My current effort is aimed at trying to integrate Assimp into a Vuforia Sample and I'll then write plain OpenGL commands to render it. I had to study NDK, C++, OpenGL all together and this is taking a while.[1] I hope you have other suggestions and that this discussion may prove helpful to others. Regards, Daniele Segato [1] Furthermore I'm encountering issues with the pre-compiled libassimp.so library provided at the link above by jazzyjester which apparently doesn't have the symbol for a aiScene de-constructor - and when I compile it own my own for some reason it say the target missmatch.

[android-developers] What is the use of services in Android?
I read about services in Android very carefully, but I didn't find any valid reasons to use it. E.g. 1. By default services run in the main thread, which most of the applications don't want. 2. A service can run on a seperate thread if it spawns it own thread. But if a service runs on a seprate thread, then the method stopService(new Intent(getApplicationContext(), MyService.class)); does not stop the running service. Again this is a problem. If we want to do some background operations, then I think threads are better than services.

Re: [android-developers] What is the use of services in Android?
Usually you use a service to coordinate a thread. FYI most of the time you don't want to outright kill a thread (e.g., if it's about to return from a download operation), you want to periodically check a flag. You probably don't want to use threads in their raw fashion (from activities) for a few reasons, one of which being that with configuration changes they're trickier to get right. Instead if you need background work that fits the model, an AsyncTask is an appropriate design.

My recommendation is Justin Wetherell's augmented reality framework. You can get the source and demo apps for free from http://code.google.com/p/android-augment-reality-framework .

[android-developers] Re: What is the use of services in Android?
Google made a mistake by saying: A Servicehttp://developer.android.com/reference/android/app/Service.html is an application component that can perform long-running operations in the background, since it makes you assume that it actually does something in the background, which it doesn't. They should have written: A Servicehttp://developer.android.com/reference/android/app/Service.html is an application component that helps manage long-running operations. It's just a way to make your code neat and ordered (especially if IPC is needed) with the added benefit of managing some life cycle events for you and restarting failed tasks.

The important part is that while an application is used to interact with the user a Service has no UI and can run in background. And with background I don't necessary mean off-the-main-thread. I mean that they can run even if the application (activities) is not used at the time. Services have a simpler life cycle in respect to activities and they are not influenced or killed by the framework by changes in configurations. Furthermore the framework will kill activities before starting to kill services. And if the framework decide to kill your service you can specify what you want to do with the request you received (drop it, ask the framework to re-do it, etc...) Services are a main component of the system and it is good practice to, for example, use them to update underling data (better if using a SyncAdapter) and manage remote calls. regards, Daniele Segato -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: buggy legacy options menu on Samsung S4
First of all, thanks for taking the time to build the demo app. It's frustrating that I'm no closer to figuring out why this is happening, but at least it doesn't seem to be an issue on *all* S4 devices. I wonder if the trait that triggers the behavior isn't hardware, but some configurable option that just happens to have one value on your phone and a different value on mine. I can't think of what it might be, though. When the options menu is in the bad state it's as if the taps aren't even registered by the device. I enabled Show Pointer Location from developer options, though, and I see visual feedback to indicate that taps are occurring inside the bounds of the menu items I'm attempting to select.

The main difference I can see when looking at your code sample on SO, is that I do *not* use an inflator to inflate the menu items from a static xml file in onCreateOptionsMenu(). Instead I am creating the menu ( sub menu) items in java code dynamically at runtime, within onCreateOptionsMenu() also onPrepareOptionsMenu(), adding removing menu items to from the menu object 'by hand', the reason I'm doing this is that the menu items need to vary according to the current context of the activity, perhaps you could try the same see if that works ok on an S4. Another suggestion, instead of creating menu items dynamically at runtime in java code - which is probably not a recommended practice, is to try your inflator code within onPrepareOptionsMenu(), remembering to call menu.clear() before the inflator and see if that works any better.

I can't think of what it might be, though. When the options menu is in the bad state it's as if the taps aren't even registered by the device. I enabled Show Pointer Location from developer options, though, and I see visual feedback to indicate that taps are occurring inside the bounds of the menu items I'm attempting to select.

When I try to reproduce your steps I do *not* get the same issues you mention, all menu options work OK when using the key combinations you mention. The main difference I can see when looking at your code sample on SO, is that I do *not* use an inflator to inflate the menu items from a static xml file in onCreateOptionsMenu(). Instead I am creating the menu ( sub menu) items in java code dynamically at runtime, within onCreateOptionsMenu() also onPrepareOptionsMenu(), adding removing menu items to from the menu object 'by hand', the reason I'm doing this is that the menu items need to vary according to the current context of the activity, perhaps you could try the same see if that works ok on an S4. Another suggestion, instead of creating menu items dynamically at runtime in java code - which is probably not a recommended practice, is to try your inflator code within onPrepareOptionsMenu(), remembering to call menu.clear() before the inflator and see if that works any better. See for details http://developer.android.com/reference/android/app/Activity.html#onPrepareOptionsMenu(android.view.Menu) Good luck.

Re: [android-developers] What is the use of services in Android?
That's not how it works, you're misunderstanding services. That's what happens if you use a thread, so in fact you're exactly switching the meaning of a service. First of all, the service won't have it's `onStart` executed until your oncreate returns anyway, since it just pushes messages onto the looper. Then the service will be started, but if it's already doing work, just recognize that by keeping some sort of state inside your service.

Re: [android-developers] What is the use of services in Android?
When you start the same service again, it just has its onstart called: nothing changes. There's no such thing as a second service created, there's only one of them in memory. Additionally: I think everyone has mentioned that services run on the main thread: how would one be running in the background and have another pop up. There's only one service, and as long as you send it messages it gets them. If you instead mean that you're having `onStart` delayed until the other one finishes, that's because it runs on the main thread. By the way, you shouldn't be doing anything in `onStart`, the same as how you shouldn't do anything blocking in activities. Again, you just *coordinate* threads using your service.

FYI most of the time you don't want to outright kill a thread (e.g., if it's about to return from a download operation), you want to periodically check a flag. You probably don't want to use threads in their raw fashion (from activities) for a few reasons, one of which being that with configuration changes they're trickier to get right. Instead if you need background work that fits the model, an AsyncTask is an appropriate design. Kris On Thu, Aug 8, 2013 at 7:40 AM, ashish ashis...@gmail.com wrote: I read about services in Android very carefully, but I didn't find any valid reasons to use it. E.g. 1. By default services run in the main thread, which most of the applications don't want. 2. A service can run on a seperate thread if it spawns it own thread. But if a service runs on a seprate thread, then the method stopService(new Intent(getApplicationContext()**, MyService.class)); does not stop the running service. Again this is a problem. If we want to do some background operations, then I think threads are better than services.

[android-developers] Feature Graphic not used anymore?
This is the note about the feature graphic: Feature Graphic (Optional): - Use: The featured section in Google Play and also on the web version of Google Play. - This graphic is *required* in order to be featured on Google Play, and is highly recommended. Without this graphic, your app cannot be featured on Google Play. However, in the latest web version of Google Play, these feature graphics are not shown. Also, the featured sections like Editor's pick seem to be using the 512x512 icon, not the 1024x500 feature graphic. Can someone offer some guidance as to whether this is still important? At least before I spend a lot of time experimenting with graphics for upcoming apps that may never be shown. If not important anymore, I can also cut out some slides from one of my presentations.

It looks about right, not too much or too little. The only bottleneck, and it might be a problem any way I go, is that I don't expect Justin Wehterell to have all the devices any more than I do. AppThwack has a few hundred in the data center, but they are not very helpful for testing something that uses sensors and camera.

[android-developers] Re: Augmented Reality frameworks - what your choice?
I think AR has enough required frameworks, which I've used without major issue. On Thursday, August 8, 2013 3:37:18 AM UTC+5:30, Nathan wrote: From your experience, what is the best option for an Augmented reality framework? If you have developed one or developed with one, please comment. There isn't a lack of options - just looking for feedback on which ones actually work. The largest list I could find on this topic is this: http://socialcompare.com/en/comparison/augmented-reality-sdks I probably need: - GPS and sensors use - Placement of markers, icons, and some vectors (lines or shapes) in the 3D world. - Should work without internet or data. Shouldn't be a problem since I am not counting on an online feed. - Non GPL. I may need ( in the dream future): - more complex 3d rendering with meshes and dynamically loaded textures. Nothing too major, just maybe like overlaying a Google Earth like image with the camera. ;) I probably don't need: - Data for the Points of Interest, I'll provide my own and they'll be small in number. - Computer Vision based reality. That eliminates quite a few. - Object manipulation - I don't need to design cities or anything like that. I'm looking for more of the viewfinder sort of thing. I prefer buy over build, I think because I don't want to start from scratch on working around the bugs on every single device. Of course, I don't want to buy and still have to fix all the bugs myself. So here are some I'm considering. - ARLab.com. As described on their website at least, it sounds like the ArBrowser - Wikitude. A bit more expensive, but possibly more established and mature. Since their sample app has a million downloads. - http://www.chupamobile.com/products/details/296/Augmented+Reality+Toolkit/. Probably made by a guy in his basement, but if it does work, it is only $20. Probably worth buying just to prototype something before going full scale. Can anyone comment?

Re: [android-developers] Re: Gradle build is screwing up in weird ways on 5% of devices when used with Proguard -- same config and source works fine in Eclipse build
So after some further follow-up I can confirm there are two fixes: 1) Just print out the value of the variable in a Log.d. Believe it or not, that fixes the code. 2) Change float into double. Based on customer reports I received, the bug only affected users running API 15 or 16, and only some models of phones, not all (again, based on customer reports). Still if you guys switch to Gradle using Proguard 4.9 with obfuscation on (even with optimization off), might want to watch out for floating point conversions in your code, or just compile with obfuscation off or export with Eclipse.
