Here i have using following code:

final CharSequence[] items = { "Twitter", "Facebook", "Gmail" };
AlertDialog.Builder builder = new AlertDialog.Builder( HomePage.this);
builder.setTitle("Share Via:");
builder.setItems(items, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
if (items[item] == "Twitter") {
Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setType("text/plain");
shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, "www.dfdfdf.com");
PackageManager pm = getPackageManager();
List<ResolveInfo> activityList = pm.queryIntentActivities(shareIntent, 0);
for (final ResolveInfo app : activityList) {
if ("com.twitter.android.PostActivity".equals(app.activityInfo.name)) {
final ActivityInfo activity = app.activityInfo;
final ComponentName name = new ComponentName(activity.applicationInfo.packageName, activity.name); shareIntent.addCategory(Intent.CATEGORY_LAUNCHER); shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
shareIntent.setComponent(name);
startActivity(shareIntent);
break;
}
else {
Toast.makeText(getApplicationContext(), "Install the twitter application/Try again later", Toast.LENGTH_LONG).show();
}
}
}

 

[out of ideas]

try putting your code into [ code] tags, not [ quote]
