Multithreading in MAF Application

• MAF application timeout

  When a MAF application is started, then came out, have any control over how long it remains in the State suspended devices Android or iOS?

  I would like a way for my application to timeout suspended, so after 30 minutes, the CRG app is restarted if it is reactivated.

  I couldn't find a lot of documentation on how to make this work, if someone can give me some advice on how to achieve this or point me to the documentation that would be greatly appreciated!

  Thank you.

  Amey,

  It's the MAF forum not the forum of the ADF.

  To answer the question: there is no way for the application to stop. If will come down and stay there until the owner of the device comes to it or explicitly closed using the gesture of the device.

  Hi all

  I just started to learn Oracle of the MAF.

• Support for generics is not available for MAF application in 12 c

  Hi Experts,

  Version of the MAF: 2.0.1.1.41.141107.1200

  Env: Andriod emulator

  Today, I tried to add a generic syntax in my application, but I've had tell compiler error

  Error (29,21): generic drugs are not supported in - source 1.4; (use - source 5 or later to enable generics) jdeveloper 12 c

  I have a right-click on project ViewController CRG App and checked the properties of the project, I found in the section of the compiler that it supports JDK 1.4 only and that is the question that I was not able to compile the generic code.

  I am not able to understand, why in Jdev 12 c IDE it has not argued for the implementation of the MAF to use higher or more recent version of the JDK.

  How can I enable superior version of the JDK in Jev 12 c

  Please refer to the fi shooting sceen my Jdev 12 c,.

  

  Kind regards

  The current version of MAF 2.0.1.X supports Java ME CDC 1.4 and you can't change that.  The next upcoming version of MAF will support Java SE JDK 1.8 profile compact 2, consisting of many candy syntax added in all older versions of Java 1.4, including generics.

• Deploy Application MAF on Win7 Jdev approx. iOS device

  Hello

  As MAF is a hybrid of Mobile development platform.

  I'm looking to deploy an application of MAF to and jDeveloper Windows 7 on an iOS device environment?

  Is it possible or I need an iOS for this machine?

  If possible how?

  XCode is only used to compile your MAF application (that you developed in JDeveloper on Mac or Windows) in iOS code.

  Ditto for the Android SDK tools but this compliles he Code Android. But the Android SDK is available for Windows and Mac.

  So if you try to deploy on a device iOS a Windows based PC, it will fail because I can't find XCode.

  So basically, you only need a Mac for XCode (which is the equivalent of Android SDK for iOS) but as the Android SDK is also available on Mac, you can use a Mac to deploy your MAF for Android and iOS application.

• Multithreading and interactions with instruments

  I have to start by saying that I'm not a great programmer. I build an instrument that requires a computer interface, and I learned how to program at the time of writing the program, for most documentation work (which means I have re-written program one half package of time I learned new things like how to define data structures and so on).

  My question is about multithreading - in my application, I use the GUI to write a series of instructions, and then I press a "Start button" which loads the instructions on a Board that interprets and outputs some call digital logic by the precisely. In addition, if specified, the button 'start' begins a task DAQmx that takes a trigger of my Board and acquires data. As these scans can take a long time, it is better for me to run in a separate thread. I also try to run an additional thread that queries the Board of Directors for its status - if it is running, waiting for a trigger or stop - and updates a control LED to reflect the State periodically. The problem I have is that programming function, the Board of Directors and the audit of the State function has some overlap, which I imagine is the reason why I'm the General Protection faults.  I read on the Thread hangs and Thread-Safe queues, but those who seem to be especially on the transmission of data between threads. Ideally I would be able to make sure that two threads do not call the same function at the same time - how would implement this?

  In addition, I don't know if it is a problem of the two threads calling the same function at the same time (I dunno if it of a problem or not), or if the problem is the fact that when I call these functions, they need to access the USB interface and there may be some sort of conflict between them.  I'm really hitting a wall here because I think that I don't have a solid understanding of the operation of allocation memory and battery function.

  Hi Paul, from your description, it seems very likely that you have problems with contemporary access to the same resource from multiple threads, which could explain the GPF you receive.

  Thread locks are a common way to handle such situations, because they can allow a single thread to protect it from another thread any access to the shared resource.

  Locks are used is:

  1 create a lock before you need to use it (possibly at the start of the program)

  2. when a thread needs to access the USB port to communicate with the instrument, it must call CmtGetLock to block access from other threads: If the lock is free, it is acquired by the threads. If it is already owned by another thread, the thread waits on the CmtGetLock until the bolt is free

  3. once a lock is finished using the shared resource, it must call CmtReleaseLock to permitt the access to the resource from other threads

  4. at the end of the program, destroy the lock

  If you do not want to stay frozen in CmtGetLock of a thread there is a function in the library if the lock is free or not, so that you can stay in a loop waiting for the lock to be free, but with the wire still alive and able to continue its work (still without access to the shared resource (, of course).

  It is crucial that acquired locks are always released, otherwise the other threads will be permanently excluded from access to the shared resource: this review is particularly important when adding threads management, because you must be sure to release locks acquired even errors, when a policy of the commune is to jump to a label inside the error handling function and it is possible that a lock is held acquired errors.

  Hello.

  I am happy that it has worked for you in the end. The CRG team will probably add an option setting somewhere in a later version of the MAF. They also suggested a more clean approach to deal with the issue than to change the XCode project template.

  First, create a file named plugin.xml and paste the following inside XML. I suggest you create the file in a central location, because it can be referenced by more than one app.

  
  
      maf-plugin-opt-out-multitaskingn
      Opt out of iOS multitasking on iOS 9
      
          
              
          
      
  
  

  Then just register the plugin in the MAF - application.xml. Things should look like this:

• URL, Cordova, MAF JS API on the Login Page

  We have difficulties to use the framework for a simple use case.

  On our custom log in HTML page, we want to add an anchor linking to our public web server where new users can register online.  All of our application is secure, which means an external URL feature is not an acceptable approach.  We must be able to navigate from the login page, to the registration page and back without using an external URL feature.

  Our first approach was simple.  After you add our domain to the whitelist of applications, we added an anchor with the URL as the HREF link.  (We also tried invoking window.open and setting window.location.href with JS).  If we add a basic anchor to the login page, the display of web pages embedded MAF navigates to our registration page, but there is no Back/fact/Close button.  Users cannot return the liaison, which is unacceptable.

  Rejecting this option so we thought that using the plugin Cordova InAppBrowser would do a better job.

  We tried the initialization of the MAF JS API nothing helps.  The Oracle online documentation shows how to add references to javascript base.js to a custom page of springboard, which allows access to Cordova, Cordova plugins and the API of JS MAF.  This same code doesn't seem to work for a custom login HTML page.  The 'showpagecomplete' event does not fire, and while the structure of the object and the JS API methods are built (adf.mf.api, adf.mf.el, etc.), called methods never call reminders of success or error in what we spend.

  Without the MAF JS API, we cannot access Cordova or the InAppBrowser plugin.  We have tested this plugin on another page AMX, so that we know that it has been installed successfully.  He can do what we need, if we can call it from our login.html page.

  Are we barking the wrong tree?  How can we add a simple link from the log in page, while allowing users to close the loaded HTML page when you're done?

  Have you considered showing your registration page server side in an iframe?

  It is a simple but powerful technique to remain in the web view of your MAF application with full control over navigation (back).

• MAF: Addition of the Cordova.Dialogue Plugin "CDVNotifications".

  Hello Oracle Community:

  If I understand the MAF sta ck is no longer ships with the Cordova.Dialogues plugin called "CDVNotistories" (see previous Discussion Forum Thread HERE)

  
  

  That is why any programmatic attempt to popup a message using the container ADFMF to invokeContainerJavaScriptFunction using the navigator.notification.alert method will fail to run. 

  
  

  Use case: I need to display the confirmation that users are connected successfully.  Here's how I did it in the ADF Mobile.

  () AdfmfContainerUtilities.invokeContainerJavaScriptFunction

  "CustomLogin.phone", "navigator.notification.alert."

  (New Object() {"successful connection.."});

  
  

  
  

  ASK:

  Implementation of an IOS directories are the files .h & ".m" to place in?  If the .h, .js files ".m" are not in the right directory I can not 'Add' the plugin in JDev.

  
  

  
  

  
  

  
  

  I spent the time to research in the Oracle documentation on the subject.  Some of the links that I've referenced are:

  Hi @,TreeStrepek,

  having the Dialogs Cordova Plugin working in the MAF 2.1.2 is trivial. Given that the MAF has full support for plugins to Cordova, it is very easy to integrate.

  You must follow the steps thees:

  1. Locate the source Cordova Plugin Dialogs: the source code is provided with the MAF extension. You can find it at [JDEVELOPER_HOME]/jdev/extensions/oracle.maf/CordovaPlugins

  

  2 source plugin copy of your MAF project: this step is optional.

  3. Add the plugin in "maf - application.xml": open the tab "Plugins". In "Additional Plugins", click on "+" button and navigate to the location of the source code of the plugin.

  

  Navigation.notification is now available to use. Now your code will work:

  () AdfmfContainerUtilities.invokeContainerJavaScriptFunction

  "CustomLogin.phone", "navigator.notification.alert."

  (New Object() {"successful connection.."});
