How to open Facebook app from within app

Both on iOs and Android, how do you open another app, for example facebook?

No. Windows Store apps cannot directly open other apps. Launching protocols out files into the default handlers is the only option.
This launch can only be done while the app is on the foreground. You're probably calling this too early. Wait for the app to be fully initialized and running.

  • How to detect JBO Exception from within Apps Module Custom Method ?

    Hi all,
    I have a custom method in apps module (AM) to set "Status" attribute to "A' in an antity, this is for approval.
    Also there is a rule that the transaction cannot be approved if it is already cancelled by another user (in multi user environment).
    The problem is :
    If the AM custom method fail (because it throws JBOException in the entity setter method), How can I know that it fails ?
    and report it back to the backing beans that call the custom method ?
    Thank you for your help,
    xtanto
    Below is the code :
    1. create a custom method in AM to do : setStatus ("A") ;
    public void approve(){
    ViewObject bphVo = findViewObject("BpHView1");
    BpHViewRowImpl vBphViewRow = (BpHViewRowImpl)bphVo.getCurrentRow();
    vBphViewRow.setStatus("A");
    2. Do a validation inside setStatus method of the entity :
    public void setStatus(String value) {
    if (! getCancel() == true )
    setAttributeInternal(STATUS, value);
    else
    throw new JboException("Error ! transaction already cancelled");
    3. On backing beans :
    public String approveButton_action() {
    BindingContainer bindings = getBindings();
    OperationBinding operationBinding =
    bindings.getOperationBinding("approve");
    Object result = operationBinding.execute();
    if (!operationBinding.getErrors().isEmpty()) {
    System.out.println("There is JBO Error !!");
    return null;
    else{
    commitButton_action();
    return "back";
    }

    Try this code:
    approveButtonAction()  {
    String navigationString = null;
    try {
    Object result = operationBinding.execute();
    naviagionString = success;
    catch (JboException e) {
       navigationString = null;
       (DCBindingContainer)bc.cacheException(e);
    } finally {
    if(navigationString != null)
      return commitButtonAction();
    else
      return navigationString;
    }

  • How to restrict the ordering of apps from within an app

    My grandkids somehow run up charges by ordering apps from within an app they are using usually games  without even knowing they are doing it. How do I restrict them from doing it?  And how do I get the charges to Itunes removed when this happens?

    You can go into settings, and restrictions and turn off 'in app purchases'
    You may also want to set your apple id from 'require after 15 minutes' to 'require immediately'
    As to getting the charges reversed you can contact the app developer. Maybe they will reverse the charges, but they don't have to. The terms of sale are that all sales are final.

  • How do I change the Apple ID that the AppStore on my iPhone defaults to? In settings I am logged into one account, but when I try and update various Apps from within the AppStore the default account that comes up, asking for my password, is different.

    Eg, the phone automatically brings up an old (defunct) AppleID account login every time I try to update my Apps. I don't know the pword for this account, nor does it have current data about me.
    But when I go to settings: store it shows me logged into the correct account.
    I have already tried:
    logging out and logging back in
    downloading a new App from within AppStore (in that case it doesn't ask me for my password or bring up the old AppleID)
    Syncing the phone, confirming that I have the right AppleID account set up on iTunes
    I don't want to have to delete all my paid apps just because I downloaded them long ago with an older Apple ID.
    Help please!

    The very similar situation with mine:
    https://discussions.apple.com/thread/3492726
    I can't find any solution. I don't even remember when I changed my apple ID! So does that means I cant recovered my purchased apps from my " old" account? I am totally innocent, for I did not intend to "Change" my account name

  • HT1689 How can I get a refund on a purchased app from the App Store?

    I purchased an app from the App Store and did not get an email receipt.  After opening the app, I found it didn't do what I thought it was designed to do.  I can't seem to find out how to get a refund from my recent purchase.  Any help would be appreciated.

    Try the 'report a problem' link from your purchase history : log into your account on your computer's iTunes via the Store > View Account menu option and you should then see a Purchase History section with a 'see all' link to the right of it ; click on that and you should see a list of your purchases ; find that app and use the 'Report a Problem' link and fill in details about the problem (iTunes support should reply within, I think, about 24 hours).
    If the 'report a problem' link doesn't work (it's been taking some people to this site on a browser instead of showing a form in iTunes) then you can try contacting iTunes support via this page : http://www.apple.com/support/itunes/contact/- click on Contact iTunes Store Support on the right-hand side of the page.

  • How do I remove images from Notes app?

    How do I remove images from Notes app?
    I sometimes find that, when cutting and pasting text from the web, an image is also copied (pretty much at all times I try and avoid this, but sometimes the selection process doesn't allow for fine enough control - e.g. a whole block of content may be selected, rather than just the few words I'm trying to copy).
    I then find, once it's part of my note, that I cannot select the unwanted image and remove it. Can anyone tell me if this is something that can be done, and if so... how?
    Thanks, Sebastain

    Hi Drew & Kilgore*
    Thanks for your replies. I also have and use Simplenote, although I went off it for a while, when it started crashing all the time on me. It seems to be more stable again now, so I'll start using it more regularly again, perhaps.
    I am, obviously, disappointed that one can't simply select ANY object within a Notes document and choose to delete it. As I rather suspected, the only solution is an annoying workaround. Apple stuff seems to get more like this as time goes by. At least in my experience.
    I solved the issue my own way in the end, but I guess it was close to your 1st idea DR, and your 2nd option, KT: I basically cut and pasted everything above, and then everything below, the image, and pasted both chunks of text into a new note. So it took two passes, and left me with the original note just displaying the image, which I then trashed.
    Tapping to the right of the image followed by deletion was what I hoped & expected would work. But instead the image stayed put and the text below the cursor would simply slide along the right hand side, moving upwards as I deleted! Most bizarre, to my mind at least.
    Anyway thanks for the feedback. But, for anyone else that might want to know how to do this, the answer is: NO, you can't select and delete an image once it's in one of your notes!
    * I quite recently watched the rather strange Bruce Willis / Nick Nolte 'Breakfast of Champions' movie... I think I still prefer the book to the film!

  • Cannot Launch .app from within Acrobat/Reader

    I made a software program that runs in/from Adobe. I burn it to DVD and sell it. Our PC users are fine, but our Mac users are having trouble. Within the program, there is a link/action set to "Open a File". The "file" is actually a Filemaker Runtime. When our Mac users click on the link/action, there is a message that says "FileMaker Pro.app is set to be launched by this PDF file......". Click "Open". The next message says "Could not open the file".
    There are 3 types of Filemaker Runtime files ending with extensions .ACR, .ZAR, .ZAS. I've created File Associations for the Mac to read these types of files and open with FileMaker. Our Mac users CAN open the files by drilling down through the folders and opening the file directly - but we don't want them to have to do this! That defeats the whole purpose of the link/action!
    My questions is: Why can't Adobe launch the FileMaker Pro.app, or open the "file" from within? Why do our customers have to go into the folder, drill down and open the file directly?

    Tembowa - Thank you for trying to help me.
    What do you mean by "next to" the PDF?
    The link/action to "launch" the .app file is "in" the PDF document.
    Please help me understand your question.

    Hi there.
    Have an iphone 3G and wen to install the Facebook app from the app store. Wen I selected install app, it said that the iphone requires IOS 4.3.
    I then plugged the phone into itunes and it said the phone was up to date (IOS 4.2.2 I think it said?). How can i install these apps, the same happened and other apps i tried to install. Any advice would be much apprecaited

    Unfortunately there is nothing that you can do and you CAN'T install these apps becuse your phone is too old.  A 3G cannot be updated beyond iOS 4.2, which is the most it can support and these apps need iOS 4.3 or above to be installed and there are no versions of these apps available.
    Developers have to place a cut off somewhere and keep developing for the most recent software that does not now include the 3G.
    If you want to install these apps on your phone, then you will have to upgrade to either an iPhone 3Gs, iPhone 4, 4s or 5.  That is all you can do because you won't be able to download these apps on an iPhone 3G - just not possible any longer.

    When i try to update my apps from the app store some of the apps wont update and ask for an Apple ID that isn't mine. Whats the problem and how do i fix it? All im trying to do is update my apps and its asking for these random apple ID's.

    The apps were purchased by another user with a different Apple ID. You will have to erase them and repurchase them using your Apple ID.

  • I have a Verizon IPhone 4 and i can't figure out how to get my ringtones from an app to my iTunes account, it doesn't have a tab for Ringtones! I have tried unplugging it and checking if would show up but it didn't, how do you enable the ringtone folder?

    I have a verizon IPhone and i can't figure out how to get my ringtones from the app to iTunes, my account doesn't have a ringtone section in the liRingtone Folder?brary, how do you enable the ringtone folder?

    Edit > Preferences.  Select the check box for Ringtones, this will add them to the listing in iTunes. 
    Not sure that really answers your question though.

  • How do you access updates to apps from the App store after changing to a new ID because the password on the old ID was changed and you don't know what it is now?

    How do you access updates to apps from the App store after changing to a new ID because the password on the old ID was changed by the former husband and you don't know what it is now?  And you set up your own new ID and account but can NOT access the updates, from the App store for the many apps that you already have, because they require that you sign in with that former now inaccessible ID and account and password?  Call it a problem of modern times and changing relationships, if you want to be charitable.

    So I guess it will only be new apps that I download that are allowed to give me their updates while 13 updates wait for me on an ID I can no longer access.
    Yes...  sorry.
    In the future, if need be, you can re download your purchases for free  >  Downloading past purchases from the App Store, iBookstore, and iTunes Store
    Good rule of thumb is to back up your purchases regardless  >  Mac App Store: Backing up your app purchases

  • How to get a Previously purchased app  from the App Store from a different account on the same computer?

    Recently had to replace my hard drive and some info has gone missing.  An App from the App Store for one.  How can I get it back now that I have a new account?  It wont let me sign on with the old one anymore.

    There's no need to create a new Apple ID just because the hard drive was replaced.
    Apps can only be re downloaded using the same Apple ID they were purchased with originally.
    You will have to re purchase the app using the new Apple ID.

  • How do I get iPhoto from the app store for my OSX Lion 10.7.5 Macbook??

    Hello,
    I have an older macbook which I was able to install OSX Lion 10.7.5 onto, and it works good with this setup.
    However I wanted to have the iPhoto app from the App Store installed on my Macbook, but looking in the App Store it says that iPhoto is compatible with OSX 10.9 or later.
    How can I get a version of iPhoto that is compatible with my OSX Lion macbook??
    Thanks.

    Install it from the computer's original disks or an iLife DVD(check sources such as Amazon or eBay if needed).

    Apps that are written for the Mac OS cannot be used on iOS devices, such as the iPad. You can purchase the iOS versions of some of these apps in the iTunes App Store.
