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

Question

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, eg 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 eg Sharing via their (Facebook's) api etc.

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 .

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();
}

Use presses a button in the action bar which triggers the above function.

If you used a ShareActionProvider instead, you could detect when a user selects a particular app from the list by implementing a ShareActionProvider.OnShareTargetSelectedListener . Otherwise you won't be able to detect which app is selected unless you implement your own activity chooser.

Here's an example:

menu

<menu xmlns:android="http://schemas.android.com/apk/res/android" >

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

</menu>

Implementation

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate your menu
    getMenuInflater().inflate(R.menu.share, menu);

    // The Intent you want to share
    final Intent i = new Intent(Intent.ACTION_SEND);
    i.setType("text/plain");
    i.putExtra(Intent.EXTRA_TEXT, "Test");

    // Set up your ShareActionProvider
    final ShareActionProvider shareActionProvider = (ShareActionProvider) menu.findItem(
            R.id.your_share_item).getActionProvider();
    shareActionProvider.setShareIntent(i);
    shareActionProvider.setOnShareTargetSelectedListener(new OnShareTargetSelectedListener() {

        @Override
        public boolean onShareTargetSelected(ShareActionProvider source, Intent intent) {
            final String packageName = intent.getComponent().getPackageName();
            if (packageName.equals("com.facebook.katana")) {
                // Do something for Facebook
            } else if (packageName.equals("com.twitter.android")) {
                // Do something for Twitter
            }
            return false;
        }

    });
    return super.onCreateOptionsMenu(menu);
}
