Android – How do I detect if user has chosen to share to Facebook or twitter using intent?

I’ve created an application which shares to facebook, twitter etc. But I want to perform different functions dependent on who the user is sharing to, for instance if the user is sharing to Facebook do one thing but if the user shares to twitter do another.

How do I do this?

My code so far is below:

private void ShareSub() {
    Intent i = new Intent(Intent.ACTION_SEND);
    i.setType("text/plain");
    i.putExtra(
            Intent.EXTRA_TEXT,
            "You've just shared "
                    + "Awesome");
    startActivity(i);
}

Further explanation of above code:

When the user presses the “menu_item_share” button in the action bar, the function above is triggered. This function then makes a box like the image below appear, which allows the user to select a particular option, e.g. Facebook or twitter. The Intent.EXTRA_TEXT is then shared to that particular app.

What I’m wanting is, when the user clicks for instance Facebook, a particular function is called e.g. Sharing via their (Facebook’s) api etc.

enter image description here

I’m not using ShareActionProvider like below:

   <item
        android:id="@+id/your_share_item"
        android:actionProviderClass="android.widget.ShareActionProvider"
        android:showAsAction="ifRoom"
        android:title="@string/share"/>

Instead, I’ve created a simple button which calls the function ShareSub:

<item
    android:id="@+id/menu_item_share"
    android:icon="@android:drawable/ic_menu_share"
    android:showAsAction="ifRoom"
    android:title="Share"/>

The reason I’ve chosen to do it this way is, I don’t want the recently shared to button to appear, as in the image below. This is causing me problems when I attempt to use the code suggested below because I haven’t used ShareActionProvider.

Answer

You can’t directly find out which app was chosen, but you can display your own Chooser dialog.

Instead of calling startActivity(i), get a list of all activities (facebook, twitter etc) that are registered to handle your intent using queryIntentActivities().

List<ResolveInfo> activities = getPackageManager().queryIntentActivities (i, 0);

Each ResolveInfo is an app that can handle your intent. Now you can show an AlertDialog containing a list of labels or icons. When the user selects a label from the list, you can handle what do to on an app-specific basis in the click handler for the dialog.

EDIT: Here’s a full working example

private void ShareSub() {
    final Intent i = new Intent(Intent.ACTION_SEND);
    i.setType("text/plain");
    i.putExtra(Intent.EXTRA_TEXT,"text");

    final List<ResolveInfo> activities = getPackageManager().queryIntentActivities (i, 0);

    List<String> appNames = new ArrayList<String>();
    for (ResolveInfo info : activities) {
        appNames.add(info.loadLabel(getPackageManager()).toString());
    }

    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("Complete Action using...");
    builder.setItems(appNames.toArray(new CharSequence[appNames.size()]), new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int item) {
            ResolveInfo info = activities.get(item);
            if (info.activityInfo.packageName.equals("com.facebook.katana")) {
                // Facebook was chosen
            } else if (info.activityInfo.packageName.equals("com.twitter.android")) {
                // Twitter was chosen
            }

            // start the selected activity
            i.setPackage(info.activityInfo.packageName);
            startActivity(i);
        }
    });
    AlertDialog alert = builder.create();
    alert.show();
}
