I’m trying to integrate Twitter in my android application. I’ve checked Android10 and abhinavblog’s code and I’ve changed just CONSUMER_KEY and CONSUMER_SECRET but I’m getting error from this block of code-
@Override
protected Void doInBackground(Void... params) {
try {
Log.i(TAG, "Retrieving request token from Google servers");
final String url = provider.retrieveRequestToken(consumer, Constants.OAUTH_CALLBACK_URL);
Log.i(TAG, "Popping a browser with the authorize URL : " + url);
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url)).setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_NO_HISTORY | Intent.FLAG_FROM_BACKGROUND);
context.startActivity(intent);
} catch (Exception e) {
Log.e(TAG, "Error during OAUth retrieve request token", e);
}
return null;
}
Logcat error is-

Why Authentication error: Unable to respond to any of these challenges: {} is empty?
I’ve give Read and Write permission On Twitter Application registration.
Any help would be greatly appreciated.
Your CONSUMER_KEY and CONSUMER_SECRET are not correct,they should be of application you have registered on twitter.
