Sound delay with air for android

Hi,
I am building a game with air for android, all work just perfect but I have just little problem with the sfx.
When I play sound I have 500 millisecond delay.
I tried to use wav format instead of mp3 and its help a bit but still there is a big delay.
Any ideas?
Thanks

First, never use the nativePath property of File.applicationDirectory (as the example does). This isn't supported on Android. You get an empty string. While you could usually bypass the write-restrictions on te application directory using this technique on the desktop, it definitely does not work on Android. Always use URLs rether than native paths to refer to application files.
What you should do is create the database in the applicationStorage directory. You could do this with SQL, or by coping a "template" database file that you packaged with the application from the application directory o the application storage directory (using the URL not the native path, of course.)

Flash cs5.5 FLVplayback Encoding Problems with Air for Android

Dear All,
I'm trying to play flv in my air application by using FLV playback in flash cs5.5.
I can play flv in the pc but not on the samsung galaxy tab andriod platform.
if anyone out there has tried out FLV playback with either an Air For Android application, where the FLV files are packaged within the app, or either streaming via normal http//:, any help would be greatly appreciated.
Thanks!

First disable autoplay. It gave errors for me. Try to make the movie play with the play() command.
to embed the movie in your air bundle, just go to publish settings for your flash project. Then in that screen go to the player settings.
In the first GENERAL tab you'll see a the bottom that you can add files to your project
Propably there is allready your .swf and an .xml file in there.
Using the + icon you can add your video.
Make sure that your video is in the same directory as your . FLA file and you can use it as is (by name)
If for example your flashfile is in c:\mytest\mytest.fla and the video in c:\mytest\videos\myvideo.flv , then you will have to load your video as "videos/myvideo.flv" with a FORWARD slash, never use \
Good luck

Using Google Play Developer License RSA code with Air for Android App?

What is the procedure for using Google Play Developer's provided license code (Base64-encoded RSA public key to include in your binary) for an Air for Android app in Flash?
I see the need to load a p12 file and have gone through the process of creating one for Air for iOS with OpenSSL but the Google provided key is in a different format. To start with it is delivered by copy/paste off a webpage.
I am using Flash CS5.5. I could switch to CS6 if neccesary.
Thanks

Garbled/scrambled text with Air for Android & GPU mode

Please excuse the big image! Has anyone come across this? As you can see the 'U' in 'Nebula' is scrambled and so are the digits below best time. It only happens within the space a character would occupy. The line under 'game' is just a reflection.
I can't work out what's causing it, it's not always the same characters that do it although the U in Nebula is always scrambled. Sometimes digits are scrambled and sometimes the same ones are not. It seems to occur with embedded fonts and with normal ones like Arial. I've tried using both Classic and TLF text, and changing anti-aliasing settings. It occurs on both dynamic and static text.
But it only happens with GPU rendering, not CPU rendering.
I can't find any mention of this at all on Google, starting to wonder if perhaps it's just my phone? (Desire S).
Any input is greatly appreciated!

Thanks for the fast reply! Switching to device fonts does fix the problem, but it means using some horrible default font rather than the one I want to, which I've embedded. I've tried a few more settings and Bitmap Text seems to fix it in some instances but not in others.

AIR for Android monetizing

I am new to this so forgive me, but i launched a paid version of an AIR for Android App and wanted to launch a free version with ads in an attempt to see how the monetizing of an app goes. Does anyone have experience doing this with AIR for android? if so what are my options?

After a lot of trouble (account canned on ADMOB ) and research, I have gotten Ads to work in all my Android Apps. This will work on a lot of AD networks, but most will ban you click fraud. Only one network allows this method and they provide support for it too.
I have over 100 games apps. with this method implemented and working. Here is a link to one of them for you to see how it will look in game. I am using multiple ads in this to force the user to click and make me some money: https://market.android.com/details?id=air.GraffitiCityMarketFree&feature=search_result
Does LeadBolt offer HTML integration for banner ads?
LeadBolt does allow banner ads to be integrated into your app using HTML, rather than using our SDK. To create a HTML banner ad after adding an app to the LeadBolt portal, simply click “Add Ad” and select “App Banner (HTML)” from the drop down box. The HTML snippet can then be added directly into your app’s HTML framework.
So far my eCPM is $6.15

                                destroyAd(null);
                                // Launch a normal browser window with the captured URL;
                                navigateToURL( new URLRequest( event.location ) );
// setup button listeners

Issue with Amazon and AIR for Android

It appears that Flash Pro CS5.5 does not create .apks properly for the Amazon Appstore. The airDownloadURL is incorrect according to Amazon and your app will likely be rejected if you try to submit it to them. In the AIR for Android Settings, when you choose "Get AIR runtime from: Amazon Appstore" in the Deployment tab, the link Flash Pro uses for the airDownloadURL property is:
http://www.amazon.com/gp/mas/dl/android/com.adobe.air
when it should be this:
http://www.amazon.com/gp/mas/dl/android?p=com.adobe.air
As far as I can tell, there is no way to edit this within Flash CS5.5 so Adobe needs to make the change in a future update. The only way I know of around this is to create your .apk manually through the command line using the AIR SDK. It should look something like this:
adt -package -target apk -airDownloadURL http://www.amazon.com/gp/mas/dl/android?p=com.adobe.air -storetype pkcs12 -keystore certificate.p12 filename.apk filename-app.xml filename.swf icon36.png icon48.png icon72.png
If you don't have any experience using the AIR SDK then do some searching online. There are a ton of good resources out there.
Good luck!
tomdei

For me works editing of Markets.xml file at:
"C:\Program Files\Adobe\Adobe Flash CS5.5\en_US\Configuration\Android\Markets.xml"
and replacing of Amazon Appstore key to
<market name="Amazon Appstore" url="http://www.amazon.com/gp/mas/dl/android?p=com.adobe.air"/>
That's all!

AudioPlaybackMode.Voice on Air for Android

Im developing an Air for Android App using Air 17 that is basically a VOIP phone. Im trying to get the Audio to come through the earpiece using the following code: SoundMixer.audioPlaybackMode = AudioPlaybackMode.VOICE; SoundMixer.useSpeakerphoneForVoice = false;
It seems to work until I start talking into the built in Mic from my android device, the audio just stops functioning all together. I tested the AudioPlaybackMode.Voice on another simple app I made where it just plays a sound file and it works perfectly.
Can anyone provide me with some insight of why this is happening or give me any advice on how to debug this issue? Thanks

Make sure that were your tutorial code uses startDrag() /stopDrag()
that you use: startTouchDrag()/stopTouchDrag()

AIR for Android video issue

On Android, in an app that I’ve developed successfully for iOS, I’m seeing this problem:
There are 5 videos built-into the app. On Samsung phones (S3 and S4), running Android 4.4.2, at the first attempt to play a video there’s sound but no picture. After returning to the video menu and attempting again, video and sound play normally. If a video is stopped and another one is started, initially a frame of the previous video is displayed (for a fraction of a second), then play resumes normally with the chosen video.
The sound-but-no-video problem does NOT show up on a Nexus 7 running 4.4.3, although the flash-frame problem does.
I’m publishing with AIR SDK 15 packaging both with and without captive runtime to try to isolate the source of the problem. I’m using <contains video> true </contains video> in the descriptor.
This feels like AIR-for-Android buggishness. Any confirmation out there? Similar problems? Workarounds?
I’ve read somewhere that AIR runtime v.3.3 may solve some video problems on Android, but not sure where to find an archived Android version of AIR that old.

Well, as it sometimes happens with me, I have spoken too soon. The answer that I marked as ‘correct’ the other day (Colin, are you there?), seems to be not quite the right answer. At least, it doesn’t solve the video problem that I’m having with some, but not all, Android devices.
After trying Colin’s suggestion – using if (stage.stageVideos.length != 0) to make sure that a stageVideoAvailabilityEvent hasn’t already fired when I try to play my first StageVideo instance – and getting perfect results in 10 consecutive tries on my Samsung S4 and S3 phones, I figured that was IT.
Next day, same devices and same code, it DIDN’T work! I pulled hair, issued profanities, hammered on the table. It didn’t matter—I still got a ‘mis-fire’ on the first play of a video whenever (almost whenever) I opened the app. After the first play everything was good – which is the exact problem that I started with many days ago. When I played Colin’s Sesame Street ‘Let’s Get Ready’ app again – the same first-play-of-video problem shows up there too.
This problem does not show up on Nexus 7 and the Samsung Galaxy 5 Tab. It is a royal p.i.t.a. on Samsung phones, where I need my app to work.
I created a bare-bones app to reproduce the problem, code below. Just a single class to play a single video with no controls. A few parameters (path to the video, and viewport stuff) are passed in from the document Class. I run it 10 times on my S4. It fails 7 times and plays well 3 times. The 'initialize2()' function never fires, proving that the stageVideos array already exists by the the time the 'initialize1()' function is called.
I'm pretty sure that this is not a coding problem (because it works well on some Androids and in iOS), but WHAT is it??

Echo cancellation in AIR for Android?

We are developing a videoconference app with versions for android and web. In android we have a lot of problems with echo cancellation, as it is only supported for desktop apps in Air 2.7 and 3.0
We have tested different codecs (speex, nellymoser), and also different mic gains, noise level sounds... but not achieved an reasonable quality.
Any recommendation about the best combination of parameters ?
Any idea if echo cancellation for mobile will be in Air 3.2 SDK for android ?
Thank you very much

I think that with the current state of the Adobe AIR Adobe FLash platforms, there is too much work to do to get echo cancellation to work on all platforms, and to get video to work as expected too. I think Adobe could solve many of these issues by implementing native WebRTC into the AIR platform, see this post here:

AIR for Android Captive Runtime

Is it possible to package android apps with AIR (or will it be) using Flash CS5.5? I don't see anything on the web about. Just how to do it with Flex and ADT etc...

Hi,
I've made a complete working example for publishing an application with captive runtime, assets and native extensions starting from Flash CS5.5
I was able to make it thanks to hints and suggestions I found in this thread.
Note: english is not my native tongue so I hope you understand what I've written also if sometime it sounds "engrish".
Here it is the link to the zip file:
    http://www.genereavventura.com/hosted/Air3NativeExtensions/AirVibrate.zip
Requirements:
- You must have Flash cs5.5 pro (obviously)
- You must have installed the overlay for Air3.0 sdk on your Flash cs5.5 pro
Here it is a link that explain how to accomplish it: http://forums.adobe.com/message/3939712
Here the steps I made.
1) Open Flash CS5.5 and create a new AIR for Android application
2) Add the swc to the libraries used by your FLA (open Actionscript 3.0 settings and add "VibrationActionScriptLibrary.swc")
   Btw, you can find this "ready to use" native extension inside the zipfile that you can download from here: http://www.adobe.com/devnet/air/native-extensions-for-air/extensions/vibration.html
   However in my example you will find also a directory named "extension" that contains it.
3) Open and then close the "air for android settings": by doing this Flash will create yourapp-app.xml file in the directory where your FLA resides.
   For example my fla is named "vibrate.fla" so Flash created for me a "vibrate-app.xml" file.
4) Make a copy of this "vibrate-app.xml" file by naming it "real-vibrate-app.xml" (or choose whatever name you want)
   I've done this because after modyfing the original one by adding the <extension> tag (see below) I wasn't able to test my app from within Flash IDE (when I compile it it simply doesn't start)
   Instead by doing this all worked fine.
5) Edit the "real-vibrate-app.xml" file by adding somewhere these lines (I added it just before the <initialWindow> tag)
    <extensions>
      <extensionID>com.adobe.Vibration</extensionID>
    </extensions>
6) Add <uses-permission android:name="android.permission.VIBRATE"/> in the <android> <manifestAdditions> part in "real-vibrate-app.xml" file.
   You should do something like this:
   <android>
      <manifestAdditions>
        <![CDATA[<manifest>
          <uses-permission android:name="android.permission.VIBRATE"/>
        </manifest>]]>
      </manifestAdditions>
   </android>
7) Develop your application
   I made a simple one that loads an external jpg and shows it on the stage: then the user can tap on it to make the phone vibrate.
   The function "doVibration" is called only when the app is running on Android Device so I do not get any executions error when I run the app from within Flash Ide
8) Publish and test it to your USB connected device by launching the "publish.bat" file I have created
   Open a dos prompt and move to your project directory then type publish.bat and press enter.
   Note: it can be that you have to edit the bat file in order to change the path to the ADT tool that comes with Air3.0 sdk
   It should be in [your adobe flash cs5.5 directory]\AIR2.6\bin\adt (rememeber, you must have installed the Air3.0 sdk overlying the old Air2.6/2.7 in the AIR2.6 directory)
   Inside the bat file you can change easily the target type (captive or not) simply by commenting/decommenting the right line.
   Captive version is about 8Mb more than the normal one but the big deal is that the user that installs it do not need the air runtime installed on his phone!
   The "big line" that creates the package is the following one:
   call %ADT_LINK% -package -target %TARGET_TYPE% -storetype pkcs12 -keystore certificate/vibrate.p12 -storepass android AirVibrate.apk real-vibrate-app.xml -extdir extensions vibrate.swf icons assets
   where:
   call %ADT_LINK%          it's just the path to the ADT tool
   -package                 it's the command that we want ADT to execute
   -target %TARGET_TYPE%    captive/non captive version
   -storetype pkcs12        certificate related
   -keystore certificate/vibrate.p12 path to your self signed certificate
   -storepass android       certificate related, I created the example certificate with "android" password and this parameters tell ADT to always use it without prompting
   AirVibrate.apk           the name of the Apk
   real-vibrate-app.xml     the apk-xml to use that is the one we modified manually above
   -extdir extensions       it's the path to the directory that contains the native extension
   vibrate.swf              the main swf
   icons                    the icons directory
   assets                   the assets directory (where I put the external jpg)
That's all.
If everything is correct, the batch file creates the AirVibrate.apk then installs it on your attached usb device and run it.
When you tap over the Android image that will appear, your phone should vibrate.
Now.. does someone wants to develop a Native Extension to show Admob banners in our Android Air Applications?
If I missed something, please let me know.
Thanks

AIR for Android: Streaming audio data won't stop unless I quit....

I write an application (AIR-Android with Flash Builder) which can play internet radio stations (streamed audio in mp3).
When I want to stop the stream like myChannel.stop() / mySound.close(); the sound is stopping but the stream is still loading (I can see it with a network monitor app).
Streaming audio data won't stop unless I quit the application or I switch my connection from WIFI to 3G or from 3G to WIFI.
I do not have this problem with Air for Mac and IOS.
How can I solve this problem ?

Hi Chris,
I received a response from a certain Wang Zhe (from Adobe) about this bug.

It should provide an example of his test that apparently it worked but I have still no answer from him.
Is it possible to contact him directly?

How can I use a file in flash cs6 that I made in flash cs5.5 air for android

I have made an app in in air for android in flash cs5.5 air for android, and I want to edit it in cs6 and play it in cs6.
But if I put Ctrl+Enter I got an error: createWin process failed with error 2: system couldn't find the file. I think the problem is that I'am using air for android 2.6 version in flash cs5.5 and version 3.2 in flash cs6. I have searched the web and found out that you can add older air versions using the sdk manager and I have tried it but first I get the error that the version of the sdk I am trying to install is not valid and after some files that I added to the sdk folder I get this error:Only SDK higher than version 3.4.2540 may be added.
I there a possible way to update the air for android for an fla or apk? Or how can I let my originally file work fine in flash cs6??

system couldn't find the file
If you can´t get a more specific hint why your project can´t compile then I can think of some reasons theis error might occur
1.You had files included besides the swf, like videos, audio files, xml files, that are not present in the place air expects them to be
2.somewhere in your createWin functions there is a class import needed that isn`t present in 3.2 anymore, for example some classes or functions from classes that were valid in 2.6 are not any more in 3.2
3. to achieve better eror logging, allow for debugging in the publishing options and see what specific lines in your code throw the error
4.any air app needs a cert file, this needs to be created once, if you migrated to e new system it might be you never created that file which air expects to even begin the compiling process
once you isolate the problem, report back

Best practice for images. Air for Android

Hey guys...
I was thinking about the best solution when it comes to images storage for Air on Android.
Since I dont have much experience with non-web based apps, I thought of two way and I would like to know your thought on them.
1.Application Storage Directory. If I get it right, this folder is created when the app is installed and the project can access files in it. Any idea on how this can work with images?
2.Database. My app uses a local database anyway so maybe that the proper way to do it. I've done some research and found out that the image must be converted to a byte array (thats easy) but then I dont have a clue on how to save it to the database.
So? Which one is better for the mobile world?
Also, if there are other ways let me know please.

While I am no expert in this area, I did run across this blog:
http://www.remotesynthesis.com/post.cfm/local-caching-of-remote-images-in-air-for-android
It deal with local caching of remotely loaded images. Should be exactly what you are looking for.

Adobe AIR for Android - GPU Mode - Bitmap Auto-Smoothing Issue

Hi everyone
I'm having a bit of an issue with the AS3 bitmap object. I'm currently developing an 8-bit style pixel game for AIR for Android.
This game is being developed at a very low resolution and is being scaled up to maintain the charm of an old retro game.
One of the methods I'm using is drawing pixels directly to bitmap objects and scaling the object up to create the old look.
When testing on a mobile device, this works beautifully when you set the rendering method to Direct but when you change
the render method to GPU the visuals go all blurry and anti-aliased (it's as if the bitmap is being smoothed out). The mini map
for example is rendered using the setPixel method and then scaled up 9 times. Looks great on my PC but once I export it to my phone
it looks absolutely awful! This is no good as I want to keep the clean, solid pixel look to maintain the the old 8-bit feel and obviously
I'd like to stick to GPU mode due to it's speed.
Like I said, this only happens once you test on a mobile device in GPU mode - it doesn't do it on my main desktop machine or
in Direct mode. I already have the stage quality set to low and I've tried setting the bitmap's smoothing property to false but
it does nothing.
Does anyone have any suggestions as to how I can get around this?

How about first blit your image to a small bitmapData, then draw it on a large bitmapData (9X larger)?
Like,
var small_bmd:BitmapData = new BitmapData(SMALL_WIDTH, SMALL_HEIGHT, false);
var large_bmd:BitmapData = new BitmapData(SMALL_WIDTH * 9, SMALL_HEIGHT * 9, false);
var bm:Bitmap = new Bitmap(large_bmd, PixelSnapping.NEVER, false);
var blitRect:Rectangle = new Rectangle(0, 0, 9, 9);
var i:uint, j:uint, blitColor:uint;
small_bmd.draw(SOURCE_IMAGE);
large_bmd.lock();
for(j = 0; j < SMALL_HEIGHT; j++){
     for(i = 0; i < SMALL_WIDTH; i++){
          blitColor = small_bmd.getPixel(i, j);
          blitRect.x = i * 9;
          blitRect.y = j * 9;
          large_bmd.fillRect(blitRect, blitColor);
large_bmd.unlock();
Not sure if the code works or not, but hopefully this helps.
