Android app crashes without any exception, when trying to sign in with Google plus

Question

I'm developing an app, which has a LoginActivity with a Google plus sign-in button. I've already Enabled the Google+ API in Google's api console and made an Oauth account.

Here is the relevant part of my code:

activity class declaration:

    public class LoginActivity extends Activity implements OnClickListener,
            ConnectionCallbacks, OnConnectionFailedListener, PlusClient.OnAccessRevokedListener {

  private PlusClient mPlusClient;
  private ConnectionResult mConnectionResult;
  private static final int REQUEST_CODE_SIGN_IN = 2

onCreate:

 protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);

        mPlusClient = new PlusClient.Builder(this, this, this)
                .setActions("http://schemas.google.com/AddActivity").build();

onClick:

     public void onClick(View view) {
        Utils.LOGD("onClick - View = " + view);

        if (view.getId() == R.id.sign_in_button) {
            Utils.LOGD("onClick  : mPlusClient status  = " + mPlusClient);
            if (mPlusClient.isConnected()) {
                Utils.LOGD("onClick - mPlusClient is connected");
                Toast.makeText(this, "you are already signed in!", Toast.LENGTH_LONG).show();
            } else {

                    Utils.LOGD(" mConnectionResult before trying to connect = " + mConnectionResult);
                    if (mConnectionResult == null) {
                        return;
                    }

                try {


                    mConnectionResult.startResolutionForResult(LoginActivity.this, REQUEST_CODE_SIGN_IN);

                } catch (IntentSender.SendIntentException e) {
                    Utils.LOGD( "Exception caught : ) " +  e.getMessage()) ;
                    mPlusClient.connect();
                }
            }

onActivityResult :

       @Override
      public void onActivityResult(int requestCode, int resultCode, Intent data) {

            if (requestCode == REQUEST_CODE_SIGN_IN) {

                  if (resultCode == RESULT_OK && !mPlusClient.isConnected()
                          && !mPlusClient.isConnecting()) {

                        // This time, connect should succeed.
                        mPlusClient.connect();

                        Utils.LOGD("onActivityResult : mConnectionResult AFTER  trying to connect = " + mConnectionResult);
                        Utils.LOGD(" onActivityResult result code   = " + resultCode);
                     
                  }
            }
      }

The problem is after I click the sign in button and Google's built in "loading.." progress bar shows, the app suddenly quits to the phone's main screen, without any error showing on the device itself NOR the in the logcat!

Also, when I come back to the app after it crashed, I see that the sign-in has finished successfully, onConnected has been called, and I am logged in with my Google account. (I have an editText showing my name after sign in)

This happens almost every time I click the button ' but not always. I've also noticed that when running the app on an emulator this crash almost never happens. (though it happened few times )

I also added logs to see when onConnected onStop and onDestroy are called

here is the logcat from when I click sign-in, to immediately after the crash:

After debugging I saw that the app crashes exactly at the line mConnectionResult.startResolutionForResult(LoginActivity.this, REQUEST_CODE_SIGN_IN)

What is wrong or what should I do?

Answer 1

Remove android:noHistory="true" from the <activity> definition of LoginActivity in your manifest. I'm pretty sure that the noHistory setting causes Android to finish the LoginActivity when it starts the Google+ signin activity. Since the activity is already finished, there won't be anything there to call onActivityResult() on. Your app isn't actually crashing, it is just done.

If you want to make sure that the user doesn't BACK into your LoginActivity you will have to solve that problem in another way (override onBackPressed() or something else).
