[android-developers] Is it possible to require a gamepad on Android TV, but not on other devices?
Hello. I'm getting ready to release a game that's compatible with both touchscreen devices and Android TV devices. On Android TV, the gameplay isn't suitable for control with just a dpad, so I'd like to add uses-feature android:name=android.hardware.GAMEPAD / to my manifest so that buyers can see that up front and (presumably) will be stopped from buying it if they don't have the appropriate hardware. But the problem is that the game also has touchscreen controls for phones and tablets, so on those devices the gamepad isn't required. What I'd really like to be able to do would be to say that *either* a gamepad or a touchscreen are required, but there doesn't seem to be a syntax for that. I thought that using multiple APKs might do the trick, and I set up one with the Android TV LEANBACK_LAUNCHER intent filter and with gamepads set to required, and another without the Android TV intent filter and with gamepads set to optional. Unfortunately, though, when I uploaded them to my draft entry on Google Play, both APKs showed compatibility with the same number of devices, so it seems that the filtering doesn't currently work to separate an Android TV build from a build for other devices. Is there any other way of achieving this, other than just being clear what the requirements are in the Play listing and hoping people read it? :) -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Is it possible to require a gamepad on Android TV, but not on other devices?
I believe I've found a way of doing this via a Stack Overflow question from someone who wanted to restrict their app to only running on Android TV: http://stackoverflow.com/questions/25152048/restrict-android-application-to-android-tv The fix was to include: uses-feature android:name=android.software.leanback android:required=true / in the manifest of the Android TV version (and to set its versionCode higher than the other build). With that the Google Play Developer Console shows the TV build only being applicable to ~11 devices or so, which seems right. The TV devices are still eligible for the non-TV build too, but because the versionCode of the TV build is higher I believe that will make them download that one. I haven't published yet, so I can't say for sure if this will work properly, but everything looks good in the Developer Console. On Tuesday, 21 July 2015 20:12:38 UTC+1, Jon Colverson wrote: Hello.

[android-developers] VideoView playback fails on 2.0.1? MediaPlayer warnings in logcat
Hello all. I'm testing an app on the 2.0.1 emulator and video playback is not working correctly. The VideoView is just showing a white rectangle, although the audio is playing fine. I tested one of the video files in the Gallery app and it showed the same results (white rectangle with sound). A beta tester with the 2.0.1 Droid update has also reported that playback isn't working; although in that case the This video can't be played message is seen rather than the white rectangles. Looking at logcat I see the following when video playback starts on the emulator: W/MediaPlayer( 524): info/warning (1, 44) I/MediaPlayer( 524): Info (1,44) D/MediaPlayer( 524): getMetadata E/SurfaceFlinger( 372): layer 0x481238, texture=4, using format 87, which is not supported by the GL E/SurfaceFlinger( 372): layer 0x481238, texture=4, using format 0, which is not supported by the GL E/SurfaceFlinger( 372): layer 0x481238, texture=4, using format 87, which is not supported by the GL E/SurfaceFlinger( 372): layer 0x481238, texture=4, using format 114, which is not supported by the GL The SurfaceFlinger messages repeat for as long as the video is playing, with formats 0, 87, 114 and 116.

Can someone point me to the setting in Eclipse for Release vs. Debug compiling. When I use the Export Wizard, I am only given the option to export unsigned. I am pretty sure I am stuck in Debug mode, since my app has no problem running in the emulator or my tethered G1. There isn't really a separate mode as such for release. When the docs refer to release mode they are just talking about signing your apk with your own private key (which is required for uploading to the Market). The latest SDK has stuff in the export wizard to help with that, but in the older releases you can only export unsigned and then sign with the command-line tools. -- Jon --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

As well as setting the SurfaceHolder format you need to tell EGL that
you want a matching config:

If you do all the compositing in software then you have to send a full frame's worth of data to the GPU every frame. Using OpenGL to then draw it would provide no benefit over just sending it straight to the screen (it would almost certainly be slower, in fact). The case where using OpenGL provides a benefit is when you have a lot of bitmap data that doesn't change. That can be just be sent to the GPU once as textures and then you can draw using those textures and the compositing will be done quickly by the GPU. If you have some bitmap data that is static, and some which changes then it is harder to predict the performance. Trying both ways is probably the only way to get a definitive answer. -- Jon --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

I am drawing using Canvas.drawBitmap and running slowing FPS, would openGL speed that up a lot you think? In short, yes. I was initially trying to use Canvas for my game, but the performance on the G1 wasn't good enough because Canvas is not currently hardware accelerated. Switching to OpenGL provided a significant boost (I'm sorry I don't have specific benchmark numbers). Interestingly, the emulator is slower than the G1 when using OpenGL because the emulator uses a (emulated) software OpenGL implementation. -- Jon --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

Hello. I notice that there's been a bit of controversy in the last couple of days about off-topic posting on this list. As the list home page says, it is intended to be a place to Discuss developing Android applications using the Android framework. While I find the talk about the Market and wider issues very interesting, I do think it would be better placed on the -discuss list, so that this list can be more focussed on technical issues to do with developing using the SDK. I wonder if the reason why this list attracts a lot of off-topic stuff is the name? I suspect many people don't see the description and just interpret android-developers to be for discussion of issues affecting developers. Perhaps if it was named android-sdk (to match the new android-ndk list), that would improve things?

Cryptography is intended to be used for, and effective at, transmitting a message secretly between two parties (A - B) without a third-party (E, for eavesdropper) being able to intercept it. The goal of DRM is transmit a message (in this case, the application) to the user's device, without the user being able to get access to it. Unfortunately the user owns the device and can do whatever they like with it, so B is the same person as E, and cryptography cannot solve this problem. If you encrypt the software then you simply move the problem. You can then put the encrypted software in plain sight, but you have to hide the keys and the temporarily unencrypted software on the device. You can try and make it difficult to find the keys, but major players have spent millions of dollars trying to do this and failed. It may take a substantial amount of effort and/or special equipment to break the DRM, but once it is broken the unencrypted software can be as freely distributed as anything else and the whole system is worthless. Also, the statement all cryptography is breakable is false. One-time pad cryptography is provably unbreakable and quantum cryptography is provably unbreakable according to known physics. More practically, RSA cryptography is effective and not proven to be breakable unless you have a quantum computer lying around or you're sitting on a proof of P=NP that you haven't gotten around to publishing yet. All DRM is breakable, and not because of the strength of any cryptography used with it. Most DRM doesn't cause anyone any pain when the content is used in the manner for which a license has been purchased, the pain tends to come when people want to use content in ways they may not have a license for (e.g. ripping a movie to a hard disk in a different format, moving software between machines). Or, Fair use as it is referred to in some jurisdictions. I'd happily accept measures to allow content providers (such as developers) to protect themselves against the minority of users who rip them off by freely handing out copies of applications because at the level we're dealing with sales of 10 or 20 No DRM can stop a determined attacker. The Android DRM stops the un- determined one. Therefore the Android DRM is as good as any DRM can be.

This is a limitation in Google Checkout, which currently only allows users to sell using their own currency.

In the Tax setup section of the Checkout settings you set the VAT rate for each EU country individually (to allow for the situation where you are registered in more than more country).

The multiple holds are described on the Checkout help here: https://checkout.google.com/support/bin/answer.py?answer=105940 (You might want to forward that to your users.)

I'm afraid I haven't the Android SQLite stuff at all yet, so I'm way out of my depth here. What I had in mind was something like closing the database in the download thread while you're doing the actual downloading and parsing and such, and then just opening it when you have a record to insert (or perhaps storing the records in a local data structure and then waiting until you have a batch of them to insert at once). -- Jon --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

2. glDrawTexfOES

not the actual texture. I use a 2d ortho with 320,480 as extents..

gl.glBindTexture(GL10.GL_TEXTURE_2D, name);

Could the problem be not binding the texture before setting the

[android-developers] Re: Need some help at testing an Android game
I ran it a few times on my G1 and I got: min: 15, 8, 15 max: 44, 44, 47 avg: 25, 24, 27 The animation is fairly smooth, but there is a brief delay (~100ms) every few seconds caused by garbage collection. On the G1 screen it often looks like there are two bullets in a row when there is only really one, which is presumably because the bullets are black and the screen's response time isn't high enough. I also tried running the demo while moving my finger around on the screen and the performance was much worse: min: 5 max: 23 avg: 13 That's probably because of the issue described here: http://groups.google.com/group/android-developers/browse_thread/thread/39eea4d7f6e6dfca which is worth looking at if you're planning to use touchscreen control in the game. -- Jon --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

At the minimum you would have to vet the applications to make sure that they comply with the Market Distribution Agreement and Content Policy. Then you would face the question of whether you want to discriminate based on app quality, and there are arguments to be made either way on that one. If you do discriminate on quality then you'd basically be in a very similar position to that of Apple with its iPhone App Store. It's not a bad idea, but if I was doing it I'd probably want more than 2% of the revenue, and I'm not sure how long it would last, because I presume that a squad of Google lawyers are working their dark magic as quickly as possible to allow people from other countries to sell directly on the Market. -- Jon --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

On Feb 13, 8:21 am, Stoyan Damov stoyan.da...@gmail.com wrote: Jon, search my posts (I have a few on this list) for touch screen - Dianne explained pretty well why touch slows the game, and a workaround for that. In short, you need to put your main thread to sleep after you handle a touch event, otherwise Android will keep pushing touch events to it and the thread simply steals CPU from your game thread. In my game I sleep the main thread 100ms after a touch is handled, taking as much as 10 touch events/sec (which is quite enough). This has completely wiped out the touch handling in traceview's profiling output. I also override dispatchTouchEvent, which short-circuits a bit more Android code. Thanks so much for the hint Stoyan! 10 events/sec wasn't appropriate for my game so I used a slightly different technique, but it's made a significant difference!

[android-developers] Re: Touch *extremely* expensive performance-wise
On Jan 11, 2:25 am, Dianne Hackborn hack...@android.com wrote: Fwiw, you should generally avoid trying to directly control scheduling. Let the kernel schedule the threads as needed; the only issue you had here was that your main thread was using as much CPU as it could get, since it was continually processing touch events, so the kernel would schedule 50/50 between that and the game thread. Simply reducing the work being done by the main thread (by our little hacky sleep solution) is probably the best way to fix things. Thank you so much for this thread! It's very very helpful to me. In my game I was getting 85 touch events per second, but I only use 1 per frame so what I've done is to synchronize my game thread with the UI thread using Object.wait(1000L) at the end of my onTouchEvent(). The game thread uses notify() and then yields once per frame so that the UI thread can fetch another event, so it effectively turns it into a polling model. So now I'm getting 60 touch events per second, which doesn't sound that different from 85, but the regularity does make a substantial difference to the smoothness of my frame rate.
