Implementing google play services in android

Question

I am going along with the tutorial here, and am getting there error The method getIntentSender() is undefined for the type ConnectionResult in the onConnectionFailed class.

Full Code

package com.alfalfa.thisthat;

import android.app.Activity;
import android.content.Intent;
import android.content.IntentSender.SendIntentException;
import android.os.Bundle;
import android.view.Menu;

import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.common.api.GoogleApiClient.ConnectionCallbacks;
import com.google.android.gms.common.api.GoogleApiClient.OnConnectionFailedListener;
import com.google.android.gms.plus.Plus;

public class LoginActivity extends Activity implements
ConnectionCallbacks, OnConnectionFailedListener {

    /* Request code used to invoke sign in user interactions. */
    private static final int RC_SIGN_IN = 0;

    /* Client used to interact with Google APIs. */
    private GoogleApiClient mGoogleApiClient;

    /* A flag indicating that a PendingIntent is in progress and prevents
     * us from starting further intents.
     */
    private boolean mIntentInProgress;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .addApi(Plus.API, null)
            .addScope(Plus.SCOPE_PLUS_LOGIN)
            .build();
    }

    protected void onStart() {
        super.onStart();
        mGoogleApiClient.connect();
    }

    protected void onStop() {
        super.onStop();

        if (mGoogleApiClient.isConnected()) {
            mGoogleApiClient.disconnect();
        }
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    public void onConnectionFailed(ConnectionResult result) {
          if (!mIntentInProgress && result.hasResolution()) {
            try {
              mIntentInProgress = true;
              startIntentSenderForResult(result.getIntentSender(),
                  RC_SIGN_IN, null, 0, 0, 0);
            } catch (SendIntentException e) {
              // The intent was canceled before it was sent.  Return to the default
              // state and attempt to connect to get an updated ConnectionResult.
              mIntentInProgress = false;
              mGoogleApiClient.connect();
            }
          }
        }

    @Override
    public void onConnected(Bundle connectionHint) {
        // We've resolved any connection errors.  mGoogleApiClient can be used to
        // access Google APIs on behalf of the user.
    }

    @Override
    public void onConnectionSuspended(int cause) {
          mGoogleApiClient.connect();
    }

    protected void onActivityResult(int requestCode, int responseCode, Intent intent) {
          if (requestCode == RC_SIGN_IN) {
              mIntentInProgress = false;

                if (!mGoogleApiClient.isConnecting()) {
                    mGoogleApiClient.connect();
                }
          }
    }
}

Solution 1

As of today and Google Play SDK version 15, this has been replaced with

result.startResolutionForResult(this, // your activity
                                RC_SIGN_IN);

as per the updated documentation.

Solution 2

Hope it helps you

result.getResolution().getIntentSender()

If I changed that line to the above the LoginActivity class doesn't show any errors, but if I run the program with an intent from MainActivity to LoginActivity, the app force closes. Is there anything else I am doing incorrectly? Thanks.

[ianhanniballake]

Post your logcat if it is force closing

[ianhanniballake]

That error looks like you haven't declared one of your Activities in your Manifest and not related to Google Play Services.

[Eric Goncalves]

thanks, that took away the error. I'm a toast saying "an internal error occurred" and the screen is flashing. not sure what that is. but ill save it for another question I guess. Thanks for your help.

Hiya, this may well solve the problem... but it'd be good if you could provide a little explanation about how and why it works :) Don't forget - there are heaps of newbies on Stack overflow, and they could learn a thing or two from your expertise - what's obvious to you might not be so to them.
