builder.setMessage("Disconnect from Instagram?")
.setCancelable(false)
.setPositiveButton("Yes",
new DialogInterface.OnClickListener() {

{
tvSummary.setText("Connected as " + mApp.getUserName());
btnConnect.setText("Disconnect");
}
}

OAuthAuthenticationListener listener = new OAuthAuthenticationListener() {
@Override
public void onSuccess() {

btnConnect.setText("Disconnect");
}
@Override
public void onFail(String error) {
Toast.makeText(MainActivity.this, error, Toast.LENGTH_SHORT).show();
}
};
private void openInstagram(Context con,String mUserName) {
 try {
  Intent iIntent = getPackageManager().getLaunchIntentForPackage("com.instagram.android");
  iIntent.setData(Uri.parse("instagram://user?username="+mUserName));   
  con.startActivity(iIntent);
 } 
catch (Exception e) {
  con.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://instagram.com/"+mUserName)));
