Android Intent for Twitter application

I'm posting this because I haven't seen a solution yet that does exactly what I want.

This primarily launches the official Twitter app, or if that is not installed, either brings up a "Complete action using..." dialog (like this) or directly launches a web browser.

For list of different parameters in the twitter.com URL, see the Tweet Button docs. Remember to URL encode the parameter values. (This code is specifically for tweeting a URL; if you don't want that, just leave out the url param.)

// Create intent using ACTION_VIEW and a normal Twitter url:
String tweetUrl = String.format("https://twitter.com/intent/tweet?text=%s&url=%s",
        urlEncode("Tweet text"), 
        urlEncode("https://www.google.fi/"));
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(tweetUrl));

// Narrow down to official Twitter app, if available:
List<ResolveInfo> matches = getPackageManager().queryIntentActivities(intent, 0);
for (ResolveInfo info : matches) {
    if (info.activityInfo.packageName.toLowerCase().startsWith("com.twitter")) {
        intent.setPackage(info.activityInfo.packageName);
    }
}

startActivity(intent);

(URL encoding is cleaner if you have a little utility like this somewhere, e.g. "StringUtils".)

public static String urlEncode(String s) {
    try {
        return URLEncoder.encode(s, "UTF-8");
    }
    catch (UnsupportedEncodingException e) {
        Log.wtf(TAG, "UTF-8 should always be supported", e);
        throw new RuntimeException("URLEncoder.encode() failed for " + s);
    }
}

For example, on my Nexus 7 device, this directly opens the official Twitter app:

If official Twitter app is not installed and user either selects Chrome or it opens automatically (as the only app which can handle the intent):

The solutions posted before, allow you to post directly on your first twitter app. To show a list of twitters app (if there are more then one), you can custom your Intent.createChooser to show only the Itents you want.

The trick is add EXTRA_INITIAL_INTENTS to the default list, generated from the createChoose, and remove the others Intents from the list.

Look at this sample where I create a chooser that shows only my e-mails apps. In my case appears three mails: Gmail, YahooMail and the default Mail.

private void share(String nameApp, String imagePath) {
    List<Intent> targetedShareIntents = new ArrayList<Intent>();
    Intent share = new Intent(android.content.Intent.ACTION_SEND);
    share.setType("image/jpeg");
    List<ResolveInfo> resInfo = getPackageManager().queryIntentActivities(share, 0);
    if (!resInfo.isEmpty()){
        for (ResolveInfo info : resInfo) {
            Intent targetedShare = new Intent(android.content.Intent.ACTION_SEND);
            targetedShare.setType("image/jpeg"); // put here your mime type

            if (info.activityInfo.packageName.toLowerCase().contains(nameApp) || 
                    info.activityInfo.name.toLowerCase().contains(nameApp)) {
                targetedShare.putExtra(Intent.EXTRA_TEXT,     "My body of post/email");
                targetedShare.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(new File(imagePath)) );
                targetedShare.setPackage(info.activityInfo.packageName);
                targetedShareIntents.add(targetedShare);
            }
        }

        Intent chooserIntent = Intent.createChooser(targetedShareIntents.remove(0), "Select app to share");
        chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetedShareIntents.toArray(new Parcelable[]{}));
        startActivity(chooserIntent);
    }
}

You can run like that: share("twi", "/sdcard/dcim/Camera/photo.jpg");
