Is there a way to open one app from another app in Air? Example: I open app A which contains a button that opens app B when clicked. Suppose both A and B are separated apps that are installed in the device and that this device could be a PlayBook, an Ipad or an Android tablet.
Thanks.
You'd have to go the Air Native Extension(ANE) route. Either create one ANE solution for iOS and Android each, or one ANE that abtracts the functionality into one solution. How to launch app A from app B on Android is not the same as on iOS. See this answer in SO.
To implement it on Android, you'd wraps the native Android Java solution in a ANE. The native Java code uses the package name of app B to launch app B from app A:
Intent intent = getPackageManager().getLaunchIntentForPackage("com.yourdoman.yourapp");
startActivity(intent);
Here is a video tutorial on how to launch an Activity through an ANE which you can build on to create your ANE. You'd have to tailor the solution to launch by domain instead of Activity.
Since I really don't know the specifics of what you are trying to do, I think I should point you here: http://www.riaspace.com/2011/08/defining-custom-url-schemes-for-your-air-mobile-applications/ It is the best answer to the question that I am aware of.
private function getHostName() : void
{
if (NativeProcess.isSupported)
{
var OS : String = Capabilities.os.toLocaleLowerCase();
var file : File;
if (OS.indexOf('win') > -1)
{
// Executable in windows
file = new File('C:\\Windows\\System32\\hostname.exe');
}
else if (OS.indexOf('mac') > -1 )
{
// Executable in mac
}
else if (OS.indexOf('linux'))
{
// Executable in linux
}
var nativeProcessStartupInfo : NativeProcessStartupInfo = new NativeProcessStartupInfo();
nativeProcessStartupInfo.executable = file;
var process : NativeProcess = new NativeProcess();
process.addEventListener(NativeProcessExitEvent.EXIT, onExitError);
process.addEventListener(ProgressEvent.STANDARD_OUTPUT_DATA, onOutput);
process.start(nativeProcessStartupInfo);
process.closeInput();
}
}
private function onOutput(event : ProgressEvent) : void
{
var strHelper : StringHelper = new StringHelper();
formStationID.text = event.target.standardOutput.readUTFBytes(event.target.standardOutput.bytesAvailable);
formStationID.text = strHelper.trimBack(formStationID.text, "\n");
formStationID.text = strHelper.trimBack(formStationID.text, "\r");
}
This code gets the workstation name. I have heard this can be done on IOS and Android, but I haven't found any proof of that yet.

I am currently developing an Android application using Cordova. This working fine so far, but now that I want to add a Chromecast button to the UI, it does not seem to work. I followed the instructions provided here: https://developers.google.com/cast/docs/chrome_sender/integrate
And this is what my code looks so far:
var CastPlayer = function() {
//...
/* Cast player variables */
/** #type {cast.framework.RemotePlayer} */
this.remotePlayer = null;
/** #type {cast.framework.RemotePlayerController} */
this.remotePlayerController = null;
//...
};
var castPlayer = new CastPlayer();
window['__onGCastApiAvailable'] = function(isAvailable) {
if (isAvailable) {
castPlayer.initializeCastPlayer();
}
};
Inline script inside my index.html.
CastPlayer.prototype.initializeCastPlayer = function() {
var options = {};
// Set the receiver application ID to your own (created in the
// Google Cast Developer Console), or optionally
// use the chrome.cast.media.DEFAULT_MEDIA_RECEIVER_APP_ID
options.receiverApplicationId = chrome.cast.media.DEFAULT_MEDIA_RECEIVER_APP_ID;
// Auto join policy can be one of the following three:
// ORIGIN_SCOPED - Auto connect from same appId and page origin
// TAB_AND_ORIGIN_SCOPED - Auto connect from same appId, page origin, and tab
// PAGE_SCOPED - No auto connect
options.autoJoinPolicy = chrome.cast.AutoJoinPolicy.ORIGIN_SCOPED;
cast.framework.CastContext.getInstance().setOptions(options);
this.remotePlayer = new cast.framework.RemotePlayer();
this.remotePlayerController = new cast.framework.RemotePlayerController(this.remotePlayer);
this.remotePlayerController.addEventListener(
cast.framework.RemotePlayerEventType.IS_CONNECTED_CHANGED,
this.switchPlayer.bind(this)
);
};
Content of my index.js.
In the index.html, I added the button like this:
<google-cast-launcher id="castbutton"></google-cast-launcher>
Now when I open my Cordova app via browser (Chrome AND Chromium), the cast button shows and I can use it normally. When I open the App on Android, the Button just does not show. Does anybody know what causes this and if it can be resolved?
We could not find a solution for Cordova, but managed it in Flutter.
We had the same challenge, and we searched high and low. Finally found this solution to make it work with: https://pub.dev/packages/dart_chromecast
Make sure your flutter compiler is downgraded to 13 or below. Otherwise, you will not be able to compile. Unfortunately, their code is not supported in a newer version of the flutter compiler and the author is not going to update anytime soon.
I'm trying to authenticate an end-user in an android app written in C# (Xamarin.Android).
I decided to try and use NuGet package Google.Apis.Oauth.v2 which seems to expose an easy to use Oauth client.
LocalServerCodeReceiver.ReceiveCodeAsync throws the following:
I get System.NotSupportedException:"Failed to launch browser with https://XXX.auth.XXX.amazoncognito.com/login?response_type=token&client_id=XXX&redirect_uri=https%3A%2F%2Fwww.google.com&scope=profile%20openid%20email for authorization. See inner exception for details."
and it has an inner exception of System.ComponentModel.Win32Exception:"Cannot find the specified file"
Code:
var clientSecret = new Google.Apis.Auth.OAuth2.ClientSecrets();
clientSecret.ClientId = ...
clientSecret.ClientSecret = ...
var initializer = new Google.Apis.Auth.OAuth2.Flows.AuthorizationCodeFlow.Initializer(
"https://XXX.auth.XXX.amazoncognito.com/login",
"https://XXX.auth.XXX.amazoncognito.com/login");
initializer.Scopes = new List<string> {"profile", "openid", "email"};
initializer.ClientSecrets = clientSecret;
var flow = new Google.Apis.Auth.OAuth2.Flows.AuthorizationCodeFlow(initializer);
var authCodeRequestURL = flow.CreateAuthorizationCodeRequest("https://www.google.com");
authCodeRequestURL.ResponseType = "token";
var uri = authCodeRequestURL.Build();
var cancellationTokenSource = new System.Threading.CancellationTokenSource();
var codeReceiver = new Google.Apis.Auth.OAuth2.LocalServerCodeReceiver();
var task = codeReceiver.ReceiveCodeAsync(authCodeRequestURL, cancellationTokenSource.Token);
Do I need to ask for a specific permission in the application manifest?
Instead of redirecting to www.google.com, I've heard you can redirect to an app, I'm not really sure how to do that, is it http://my_app_package_name or http://my_app_title, something else?
Is it possible not to rely on that library for launching the browser and instead get the RequestUri and start an Activity, if so how will the app become aware the end-user completed the SignIn process and how will the app retrieve the token?
Sorry, but Google.Apis.Oauth.v2 does not support Xamarin, and there's no simple way to get it working.
Unfortunately no Google.Apis.* packages currently support Xamarin.
You might find the Xamarin.Auth package does what you want?
I've figured out how to redirect to an app after authentication in the browser completes.
It's called a "Deep Link" and it's documented at enter link description here, essentially you need to declare an IntentFilter on your Activity, which registers with the Android OS that if someone clicks or an page redirects to a specific URI, your app gets called. The token that's appended to the URI can then be read inside your app.
I'm using this nu-get package to stream mp3 url in a Xamarin Android project:
https://github.com/martijn00/XamarinMediaManager
I followed the instructions in the link up there... and it shows the music playing in the notification bar but it is not working (no sound and it's not even starting the song).
Code snippet:
clickButton.Click += (sender, args) =>
{
ClickButtonEvent();
};
private static async void ClickButtonEvent()
{
await CrossMediaManager.Current.Play("http://www.montemagno.com/sample.mp3");
}
I built the sample included in the link, and I got the same result from their sample. Also deployed on real device too, same result!
Image:
Am I missing something ?
Or is the library broken ?
I ran into this using Android Emulator on Hyper-v. It turns out that the network is set to internal. So the http://www.montemagno.com/sample.mp3 could not be found. My workaround:
Hyper-v -> Virtual Switch Manager, add an external network.
Hyper-v -> Virtual Machines->Settings, add new hardware->Network adapter and set to external network.
"Visual Studio Emulator for Android" desktop app, launch phone vm,
in Visual Studio, deploy and run app.
Sound should work from external source now.
Permissions maybe? In the project site it states that for Android:
You must request AccessWifiState, Internet, MediaContentControl and
WakeLock permissions
By default example use ExoPlayerAudioService.
There are issue with url escape in ExoPlayerAudioService.GetSource method
private IMediaSource GetSource(string url)
{
string escapedUrl = Uri.EscapeDataString(url);
var uri = Android.Net.Uri.Parse(escapedUrl);
var factory = URLUtil.IsHttpUrl(escapedUrl) || URLUtil.IsHttpsUrl(escapedUrl) ? GetHttpFactory() : new FileDataSourceFactory();
var extractorFactory = new DefaultExtractorsFactory();
return new ExtractorMediaSource(uri
, factory
, extractorFactory, null, this);
}
string escapedUrl = Uri.EscapeDataString(url);
I.E. http://example.com/path_to_audio.mp3 will be escaped to "http%3A%2F%2Fexample.com%2Fpath_to_audio.mp3" as result HTTP error.
To fix just skip url escape.
I'm developing Phonegap application (using AngularJs+Bootstrap) which supports iOS and Android. We had to maintain two code bases so far but its the same functionalities, only few differences like below.
Application name/icons are different
Main url is different for web-service calls
Ex :
PhoneGap App X : call http://abc/xappinfo weservice, use x_icon_app.png
(This has to build for both iOS and Android which i have no issue)
PhoneGap App Y : call http://xyz/yappinfo weservice, use y_icon_app.png and other UI elements for mobile skin
(This also has to build for both iOS and Android)
Both PhoneGap App X and Y uses same code for business logics.
I would like to maintain one code base for both apps since there only few differences. Is there any way I could achieve this or simplify my development effort?
I had a similar situation. I placed all my app folders in a single folder and placed the following code in a file in the root folder called: persist.js. Its purpose is to persist file changes across all of the different apps keeping the same path. It is a little manual, but works...
var fs = require('fs');
var chalk = require('chalk');
var argv = require('minimist')(process.argv.slice(2));
var file = argv.f;
var apps = [
'app_folder_1',
'app_folder_2',
'app_folder_3',
'app_folder_4',
'app_folder_5',
];
if(file){
if (fs.existsSync(file)) {
console.log(chalk.blue('Found source file'));
var fileWithoutApp = file.substring(file.indexOf('/'));
apps.map(app => {
fs.writeFileSync(app + fileWithoutApp, fs.readFileSync(file));
console.log(chalk.green(`File copied to: ${app + fileWithoutApp}`))
});
} else {
console.log(chalk.red('File does not exist'));
}
} else {
console.log(chalk.red('No file specified'));
}
After changes are made to a file within any of the project folders just call the following from the command line:
node persist -f [relative path to your file that has changes]
This will persist the change across all projects. Like I said, a little manual... but effective :)
When u use cordova or ionic + angularjs you can compile application for both device this is more simple you like complication !!
We are trying to implement a simple solution to our website developed via Flex and mobile apps developed using Adobe Air.
1) Our users would like to import their facebook friends onto website via www.ourwebsite.com and also via the Ourwebsite android, ios & blackberry apps.
2) We want to use the Facebook Requests dialog which allows users to select their friends and send multiple invitations at a time
3) When the recepient clicks on the notification he receives
in case of web, it should direct the notification recipient to www.ourwebsite.com
in case of mobile app, it should re-direct to respective appstore to download our app.
We tried several configurations but it's not working for us.
As previously said we have developed our website using Adobe Flex and our Mobiles apps run using Adobe Air. Do we need to install the Facebook native SDK's into our code?
Strangely the exact same requirement is working for www.naaptol.com and 9lessons.info.
But we're unable to achieve the same technique.
Can anyone guide us or advise if we're missing any important aspect of Facebook App & its policies.
Thank you.

So if I think I am understanding this right, you want to be able to open a link differently based upon the platform they are on. Here is some js that will do it for ios and android. If they have your app installed it will launch the app, otherwise it will send them to the app store
// if iPod / iPhone, display install app prompt
if (navigator.userAgent.match(/(iPhone|iPod|iPad);?/i) || navigator.userAgent.match(/android/i)) {
var store_loc = "itms://itunes.com/apps/youriOSApp";
var href = "yourPrefix://";
var is_android = false;
if (navigator.userAgent.match(/android/i)) {
store_loc = "https://play.google.com/store/apps/details?id=air.com.your.app";
is_android = true;
}
var app_loc = href;
if (is_android) {
var w = null;
try {
w = window.open(app_loc, '_blank');
} catch (e) {
// no exception
}
if (w) {
window.close();
} else {
window.location = store_loc;
}
} else {
var timeout = null;
window.location.replace(app_loc);
timeout = setTimeout(function () {
"use strict";
window.location = store_loc;
}, 300);
onblur = function () {
"use strict";
clearTimeout(timeout);
};
}
}
