Question

Wow, Ive been trying to get a simple Android Twitter app to work but its been impossible. I come from an iOS background. Im currently trying to make these work:

1. MyTwitter app from Marakana. http://marakana.com/forums/android/examples/312.html

2. Marakana Simple OAuth demo. https://github.com/marakana/OAuthDemo

3. Twitter4j Sample itog_lab. https://github.com/itog/Twitter4j-android-Sample

4. AndroidTwitterSample. http://www.android10.org/index.php/articleslibraries/291-twitter-integration-in-your-android-application#josc329

I always get unauthorized error unable to request access token. Has anyone had this experience?

If you are content with calling Twitter using Intent (meaning that you will need the Twitter app already installed for this to work), you can access Twitter with something like this:

try{
    Intent intent = new Intent(Intent.ACTION_SEND);
    intent.putExtra(Intent.EXTRA_TEXT, "It's a Tweet!" + "#MyApp");
    intent.setType("text/plain");
    final PackageManager pm = getPackageManager();
    final List<?> activityList = pm.queryIntentActivities(intent, 0);
    int len =  activityList.size();
    for (int i = 0; i < len; i++) {
        final ResolveInfo app = (ResolveInfo) activityList.get(i);
        if ("com.twitter.android.PostActivity".equals(app.activityInfo.name)) {
            final ActivityInfo activity=app.activityInfo;
            final ComponentName name=new ComponentName(activity.applicationInfo.packageName, activity.name);
            intent=new Intent(Intent.ACTION_SEND);
            intent.addCategory(Intent.CATEGORY_LAUNCHER);
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
            intent.setComponent(name);
            intent.putExtra(Intent.EXTRA_TEXT, "It's a Tweet!" + "#MyApp");
            startActivity(intent);
            break;
        }
    }
} catch(final ActivityNotFoundException e) {
    Log.i("Twitter intent", "no twitter native", e );
}
