    We've developed a library to hide the finer details of In App Billing in
    Version 2 from client applications. Now we're planning to upgrade to
    Version 3 and I've hit a snag.
    Currently the application (Activity) using the library creates an instance
    of the library object and calls methods to get products available for sale,
    and purchase products etc. When purchasing products the library handles
    verifying receipts via a secure server and provisioning the purchased
    products etc., there is quite a bit going on behind the scenes. The library
    has no UI, instead it returns data to the calling application which handles
    all the UI operations such as listing products and displaying dialogs using
    response coded from our library.
    There is a clear line between the application, and the library.
    Now looking at Version 3 I discover this comment in iabHelper for
    Initiate the UI flow for an in-app purchase. Call this method to initiate
    an in-app purchase,
    which will involve bringing up the Google Play screen. The calling activity
    will be paused while
    the user interacts with Google Play, and the *result will be delivered via
    the activity's*
    *{@link android.app.Activity#onActivityResult}* method, at which point you
    must call
    this object's {@link #handleActivityResult} method to continue the purchase
    flow. *This method*
    *MUST be called from the UI thread of the Activity.*
    Does this mean the calling activity MUST implement the onActivityResult
    Also can we launchPurchaseFlow from the library object (which is not an
    Is there any easy way to maintain separation between the application and
    our billing library?
    Any tips or ideas greatly appreciated.

    Require the client activity to implement some interface and pass it as a
    parameter to your library's method's as needed. It doesn't really matter
    where you launch stuff from as long as it is using the right thread
    (UI thread) and context (the activity's).
    Additionally, you don't really need to use IabHelper at all, you can see
    what it does (basically connect to a remote service and call its methods,
    sometimes in a worker thread) and implement something similar. You
    can't skip the onActivityResult() part though.

    I haven't tried it, but probably. You can also use a Handler created on the
    UI thread to achieve the same thing.

    I have a tablet running Android 4.2 with multiple users. I want to install
    certificates which can be accessed by the secondary user (basically I want
    to configure an Email account in the secondary user which requires
    certificates). I installed certificates in the primary user. But, when I
    try to access them in the secondary user, the dialog doesn't display the
    installed certificates.
    I also tried modifying the Settings application to show the "Install
    certificates" option in the secondary user. But, clicking that option shows
    a toast that "Only owner can install certificates". I went a step further
    and changed CertInstaller to allow secondary users to install certificates.
    But, it fails when Android attempts to write the certificates to
    /data/misc/keychain directory.
    My question is that, is /data/misc/keychain directory only accessible
    (read/write access) to applications running inside the primary user
    (owner). If yes, the how the access control is enforced?

    What's the recommended api for doing http/https in Android.
    I think there's 2-3 of them.

    Just the org.apache ones...?

    Here's the code for it:
    * Return whether the state matches the desired stateSpec.
    * @param stateSpec an array of required (if positive) or
    * prohibited (if negative) {@link android.view.View} states.
    * @param state a {@link android.view.View} state
    public static boolean stateSetMatches(int[] stateSpec, int state) {
    int stateSpecSize = stateSpec.length;
    for (int i = 0; i < stateSpecSize; i++) {
    int stateSpecState = stateSpec[i];
    if (stateSpecState == 0) {
    // We've reached the end of the cases to match against.
    return true;
    if (stateSpecState > 0) {
    if (state != stateSpecState) {
    return false;
    } else {
    // We use negative values to indicate must-NOT-match states.
    if (state == -stateSpecState) {
    // We matched a must-not-match case.
    return false;
    return true;

    How can I schedule a daily popup dialog box (that appears to remind the user to do something) that remains visible until it is manually closed by the user?
    Would a service be utilized? If so how? Or would an alarm be the best solution. If the app is killed or restarted can the popup still be scheduled to happen?
    Thanks for your suggestions.

    Use AlarmManager to schedule a PendingIntent that starts an Activity that
    has a dialog theme.

    Is there any way to detect whether an activity was started by the
    Android os launcher as opposed to another activity.
    Or put another way - is there wa way to force an activity not
    be launchable (sp?) by another activity.

    What happens when users install a different launcher...?

    Hi Everyone,

    I wanted to let you know that I have created 3 discussion groups for using
    and developing for the Samsung Galaxy Note series of devices. The new
    discussion groups are created specifically for utilizing and developing
    apps using Samsung's S-Pen functionality.

    Please feel free to join the groups. The groups are:

    - S-Pen App Discussion
    - S-Pen App Development - Beginners
    - S-Pen App Development-Advanced

    Happy Coding!

    Make sure you are sending the variables via the POST method and not the GET

    That thread is all the information we have - the ability to reply to users
    is by invitation only for the moment.
    It would be better to continue this discussion in the above thread
    (discussion group) rather than in this the SDK group.
