Solution to "Invalid Bundle Structure - The binary file ... is not permitted. Your app may contain only one executable file" for apps built by Phonegap

Posting to Apple as we all know is a pain in the ass.

For the last few days I've been trying to debug my app to submit it to Apple. I use Application Loader to upload the app and the biggest hurdle I ran into was the error:

Invalid Bundle Structure - The binary file 'xx.app/xx' is not permitted. Your app may contain only one executable file. Refer to the Bundle Programming Guide for information on the iOS app bundle structure.

After hours of pulling hair here is how I solved it:

  1. After compiling your app with Phonegap remove:
    1. platforms > ios > build > simulator
    2. platforms > ios > build > device
  2. Open platforms > ios > projectName.xcodeproj
  3. Go to Product in xcode then Scheme > Edit Scheme > executable = projectName.app
  4. Go to Product in xcode then Scheme > Edit Scheme > Build Configuration = Release
  5. Replace with your app icons all icons under platforms > ios > projectName > Resources > icons
  6. Replace with your app splash screen images all images under platforms > ios > projectName > Resources > splash
  7. Add all images from splash and icons folders in config.xml file
  8. Zip your directory, upload to Phonegap, download IPA from Phonegap, Upload with Application Loader
That's all. I hope this help someone.

Step by step on how to add Facebook plugin on Phonegap

I have posted an answer on stackoverflow on how to do it and here is more:

Using CLI add the APP_ID and APP_NAME variables to your command. Something like this:

C:\myProject>cordova plugin add https://github.com/phonegap/phonegap-facebook-plugin --variable APP_ID=your_facebook_app_id --variable APP_NAME=your_facebook_app_name
I got it installed this way but not sure if the app is functional or not. Something to test.
I had an issue with phonegap build giving me the error One of your plugins requires a parameter: APP_ID, APP_NAME. That was because I didn't add those variables to the config.xml file.
This solved it


<gap:plugin name="com.phonegap.plugins.facebookconnect">
  <param name="APP_ID" value="your_facebook_app_id" />
  <param name="APP_NAME" value="your_facebook_app_name" />
</gap:plugin>

Please remember to modify the plugin.xml file under root/plugins/com.phonegap.plugins.facebookconnect/plugin.xml
<preference name="APP_ID" />
<preference name="APP_NAME" />

Also, I had issue with facebook failing to initial and it was because my config.xml had this
<widget id="com.app.xxx" version="0.0.1" xmlns="http://www.w3.org/ns/widgets" xmlns:gap="http://cordova.apache.org/ns/1.0">

and solved it by changing it to this:
<widget id="com.app.xxx" version="1.0.0" xmlns="http://www.w3.org/ns/widgets" xmlns:gap="http://phonegap.com/ns/1.0">

This should get the app to work.

After you start using it you will notice when you do login facebook will through at you errors like "invalid android_key parameter". This means that you haven't register the app platform on Facebook.

Go to your app facebook page: https://developers.facebook.com/x/apps/app_id/settings/
Under Settings -> Basic -> click on add platform

Now you need to sign your app using command line on windows, for this to work you will need to have java keytool installed and i'm not going through that here, PLEASE KEEP IN MIND TO AVOID ADDING SPACES, SPECIAL CHARACTERS AND ALL LOWER CASE [I had issues with phonegap not recognizing my alias because of that].

C:\mykeystorebox>keytool -genkey -v -keystore mynewkey.keystore -alias mykeyalias -keyalg rsa -keysize 2048 -validity 10000
Enter keystore password:
Re-enter new password:
What is your first and last name?
[Unknown]: sean
What is the name of your organizational unit?
[Unknown]:
What is the name of your organization?
[Unknown]: testcompany
What is the name of your City or Locality?
[Unknown]: london
What is the name of your State or Province?
[Unknown]: on
What is the two-letter country code for this unit?
[Unknown]: ca
Is CN=sean, OU=Unknown, O=testcompany, L=london, ST=on, C=ca correct?
[no]: yes

Generating 2,048 bit RSA key pair and self-signed certificate (SHA256withRSA) with a validity of 10,000 days
for: CN=sean, OU=Unknown, O=testcompany, L=london, ST=on, C=ca
Enter key password for
(RETURN if same as keystore password):
[Storing mynewkey.keystore]

C:\mykeystorebox>keytool -exportcert -alias mykeyalias -keystore mynewkey.keystore | openssl sha1 -binary | openssl base64
Enter keystore password: *************
Abikekw4k3lfmK23kvJl32Ljflw301=

Now go back to facebook page and take Abikekw4k3lfmK23kvJl32Ljflw301= and put it under Key Hashes. You will need to add your app class in there too.

Save that.

Now go to Phonegap and upload your keystore as a key for your android and sign your APK with it. It will ask for a title and could be anything, alias and in this case should be mykeyalias.

Push Notification Android - Phonegap 3.2 Plugin

I have been trying to test the native phonegap push notification on version 3.2 but almost everything I tried resulted in "Class not found" issue". After a couple of days of trials here is how I finally got it to work.


  1. Using the CLI install the push notification plugin: 
    • $ phonegap local plugin add https://github.com/phonegap-build/PushPlugin
  2. Add
     <script type="text/javascript" src="PushNotification.js"></script>  
    
    to the header of your index.html
  3. Add the following to your index.html body
               <div id="home" style="position:absolute; bottom:0; left:0; z-index:99999;">  
                    <div id="app-status-div">  
                         <ul id="app-status-ul">  
                              <li>Cordova PushNotification Plugin Demo</li>  
                         </ul>  
                    </div>  
               </div>  
    
  4. In your javascript add
     var pushNotification;  
           function onDeviceReady() {  
             $("#app-status-ul").append('<li>deviceready event received</li>');  
                         document.addEventListener("backbutton", function(e)  
                         {  
                  $("#app-status-ul").append('<li>backbutton event received</li>');  
                            if( $("#home").length > 0)  
                              {  
                                   // call this to get a new token each time. don't call it to reuse existing token.  
                                   //pushNotification.unregister(successHandler, errorHandler);  
                                   e.preventDefault();  
                                   navigator.app.exitApp();  
                              }  
                              else  
                              {  
                                   navigator.app.backHistory();  
                              }  
                         }, false);  
                         try   
                         {   
                  pushNotification = window.plugins.pushNotification;  
                  if (device.platform == 'android' || device.platform == 'Android') {  
                                   $("#app-status-ul").append('<li>registering android</li>');  
                    pushNotification.register(successHandler, errorHandler, {"senderID":"661780372179","ecb":"onNotificationGCM"});          // required!  
                              } else {

                    pushNotification.register(tokenHandler, errorHandler, {"badge":"true","sound":"true","alert":"true","ecb":"onNotificationAPN"});     // required!  
                  }  
             }  
                         catch(err)   
                         {   
                              txt="There was an error on this page.\n\n";

           }  
           // handle APNS notifications for iOS  
           function onNotificationAPN(e) {  
             if (e.alert) {  
                $("#app-status-ul").append('<li>push-notification: ' + e.alert + '</li>');  
                navigator.notification.alert(e.alert);  
             }  
             if (e.sound) {  
               var snd = new Media(e.sound);  
               snd.play();  
             }  
             if (e.badge) {  
               pushNotification.setApplicationIconBadgeNumber(successHandler, e.badge);  
             }  
           }  
           // handle GCM notifications for Android  
           function onNotificationGCM(e) {  
             $("#app-status-ul").append('<li>EVENT -> RECEIVED:' + e.event + '</li>');  
             switch( e.event )

           function successHandler (result) {  
             $("#app-status-ul").append('<li>success:'+ result +'</li>');  
           }  
           function errorHandler (error) {  
             $("#app-status-ul").append('<li>error:'+ error +'</li>');  
           }  
                    document.addEventListener('deviceready', onDeviceReady, true);  
    
  5. Now go to your www/config.xml and add
     <gap:plugin name="com.phonegap.plugins.PushPlugin" />  
    
Now build and compile your project. You should get it working now.

So what's next?! When you run your app and registration is success what you need to play with is e.regid under the case: "registered".

 So what you could do is using ajax send the e.regid to a php file to store that regid in the database as an identity to this user's device.

Next you could test sending the user messages using something like:
 function send_gcm_notify($reg_id, $message) {  
      $apiKey = "AIzaSyDXlsn2rlbTxZsa3apYfQu0kaSNzzzzzag8"; //google browser api key  
      $url = 'https://android.googleapis.com/gcm/send';  
   $fields = array(  
     'registration_ids' =>; array( $reg_id ),  
     'data'       =>; array( "message" => $message ),  
   );  
   $headers = array(  
     'Authorization: key=' . $apiKey,  
     'Content-Type: application/json'  
   );  
   $ch = curl_init();  
   curl_setopt($ch, CURLOPT_URL, $url);  
   curl_setopt($ch, CURLOPT_POST, true);  
   curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);  
   curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);  
   curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

Push Notification - Phonegap 3.0+ with pushwoosh

I had so much trouble integrating Push Notification using all the documentation available. After two days of struggle I got to the bottom of it and finally it's working. Here's what I did.
  1. If you installed Push plugin before, then delete it and start fresh.
  2. Follow the instructions in here integrating phonegap on android
  3. In your config.xml file add < gap:plugin name="com.pushwoosh.plugins.pushwoosh" version="3.0.1" > < /gap:plugin > ....... PLEASE NOTE THE SPACES I ADDED BEFORE AND AFTER THE TAGS IN HERE. REMOVE THE EXTRA SPACING
  4. projectid: is actually the Project Number under your Developers Console > overview.
  5. That's it.

Passing parameters from HTML to swf(Flash Builder) AS3

I spent countless hours to get this done. Pulled my hair broke my glasses and kicked out my cat all because of lack of finding the right directions on how to get it done.

simple as this:

your flex file is ready! OK



private var in1:String;
private function initHandler():void {
var obj:Object = this.parameters;
in1= obj.name;
Alert.show("OK " + in1);
}


There goes the flex file
Now, when you publish your project using the project>Export Release Build... you need to edit the exported html file (it should be under the same name as your project). So go and edit it


Find the line



//within the 3rd [script] and after (REPLACE [ WITH < )
var xiSwfUrlStr = "playerProductInstall.swf";
//add this line
flashvars.in1= "WELCOME"; // don't forget ;
var ver= {};
var params = {};

//then you will have [nonscript][object]
//add


//then another[object]
//add



THAT'S IT :D
