Android Intent for Twitter Application

Android launch Twitter intent

Typically for launching a user's feed

Intent intent = null;
try {
    // get the Twitter app if possible
    this.getPackageManager().getPackageInfo("com.twitter.android", 0);
    intent = new Intent(Intent.ACTION_VIEW, Uri.parse("twitter://user?screen_name=USERID"));
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
} catch (Exception e) {
    // no Twitter app, revert to browser
    intent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://twitter.com/USERID_OR_PROFILENAME"));
}
this.startActivity(intent);

For Post Intent

Intent tweetIntent = new Intent(Intent.ACTION_SEND);
tweetIntent.putExtra(Intent.EXTRA_TEXT, "This is a Test.");
tweetIntent.setType("text/plain");

PackageManager packManager = getPackageManager();
List<ResolveInfo> resolvedInfoList = packManager.queryIntentActivities(tweetIntent,  PackageManager.MATCH_DEFAULT_ONLY);

boolean resolved = false;
for(ResolveInfo resolveInfo: resolvedInfoList){
    if(resolveInfo.activityInfo.packageName.startsWith("com.twitter.android")){
        tweetIntent.setClassName(
            resolveInfo.activityInfo.packageName, 
            resolveInfo.activityInfo.name );
        resolved = true;
        break;
    }
}
if(resolved){
    startActivity(tweetIntent);
}else{
    Toast.makeText(this, "Twitter app isn't found", Toast.LENGTH_LONG).show();
}

Android Intent for Twitter application

It is entirely possible your users will only ever, now and forever, only want to post to Twitter.

I would think that it is more likely that your users want to send information to people, and Twitter is one possibility. But, they might also want to send a text message, or an email, etc.

In that case, use ACTION_SEND, as described here. Twidroid, notably, supports ACTION_SEND, so it will appear in the list of available delivery mechanisms.

How can I post on Twitter with Intent Action_send?

I'm using this snippet on my code:

private void shareTwitter(String message) {
    Intent tweetIntent = new Intent(Intent.ACTION_SEND);
    tweetIntent.putExtra(Intent.EXTRA_TEXT, "This is a Test.");
    tweetIntent.setType("text/plain");

    PackageManager packManager = getPackageManager();
    List<ResolveInfo> resolvedInfoList = packManager.queryIntentActivities(tweetIntent, PackageManager.MATCH_DEFAULT_ONLY);

    boolean resolved = false;
    for (ResolveInfo resolveInfo : resolvedInfoList) {
        if (resolveInfo.activityInfo.packageName.startsWith("com.twitter.android")) {
            tweetIntent.setClassName(
                    resolveInfo.activityInfo.packageName,
                    resolveInfo.activityInfo.name);
            resolved = true;
            break;
        }
    }
    if (resolved) {
        startActivity(tweetIntent);
    } else {
        Intent i = new Intent();
        i.putExtra(Intent.EXTRA_TEXT, message);
        i.setAction(Intent.ACTION_VIEW);
        i.setData(Uri.parse("https://twitter.com/intent/tweet?text=" + urlEncode(message)));
        startActivity(i);
        Toast.makeText(this, "Twitter app isn't found", Toast.LENGTH_LONG).show();
    }
}

private String urlEncode(String s) {
    try {
        return URLEncoder.encode(s, "UTF-8");
    } catch (UnsupportedEncodingException e) {
        Log.wtf(TAG, "UTF-8 should always be supported", e);
        return "";
    }
}

Hope it helps.

Open page in Twitter app from other app - Android

This worked for me: twitter://user?user_id=id_num
