Android Login with Google Plus

Question

I've been following this tutorial. http://www.androidhive.info/2014/02/android-login-with-google-plus-account-1/

But when I'm tested the app through the real device, When I click on the Sign in button, a toast is appeared saying "An internal error has occurred"

Could you please help me with this. Thanks in advance.

Answer 1

Usually 'Internal error' shows up if one of the following is wrong:

In Google's Developer console website :

1. You have created a project, but not enabled Google api

Inside the Project:

Credentials

1. SHA1 Code is not correct
2. Package Name is not correct

Consent Screen

1. The associated email address is missing
2. Product Name is missing

If all these are correct, it should work automatically....

Answer 2

Try below code:

private static final int REQUEST_CODE_RESOLVE_ERR = 9000;
    private static final int REQUEST_CODE_SHARE = 1000;
    private PlusClient mPlusClient;
    private PlusClient.Builder mPlusClientBuilder;
    private PlusShare.Builder mPlusShareBuilder;


// In your onCreate()
mPlusClientBuilder = new Builder(this, this, this);
        mPlusClientBuilder.setScopes(Scopes.PLUS_LOGIN, Scopes.PROFILE);
        mPlusClient = mPlusClientBuilder.build();
mPlusClient.connect();

// Overrides methods

@Override
    public void onConnectionFailed(ConnectionResult result) {
        if (result.hasResolution()) {
            // The user clicked the sign-in button already. Start to resolve
            // connection errors. Wait until onConnected() to dismiss the
            // connection dialog.
            try {
                result.startResolutionForResult(this, REQUEST_CODE_RESOLVE_ERR);
            } catch (SendIntentException e) {
                mPlusClient.disconnect();
                mPlusClient.connect();
            }
        }
    }

    @Override
    public void onConnected(Bundle arg0) {
        String accountName = mPlusClient.getAccountName();
        btnSignIn.setText(getString(R.string.signout));
        textUserName.setText(accountName);

    }

// Signin Click event

btnSignIn.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                if (!mPlusClient.isConnected() && btnSignIn.getText().equals(getString(R.string.signin))) {
                    mPlusClient.connect();
                } else if (mPlusClient.isConnected() && btnSignIn.getText().equals(getString(R.string.signout))) {
                    mPlusClient.clearDefaultAccount();
                    mPlusClient.disconnect();
                    btnSignIn.setText(getString(R.string.signin));
                    textUserName.setText("");
                    txtLoginAs.setVisibility(View.GONE);



                }
            }
        });

//onActivityResult

@Override
    protected void onActivityResult(int requestCode, int responseCode, Intent data) {
        super.onActivityResult(requestCode, responseCode, data);
        if (requestCode == REQUEST_CODE_RESOLVE_ERR && responseCode == RESULT_OK) {
            mPlusClient.disconnect();
            mPlusClient.connect();
        } else if (requestCode == REQUEST_CODE_SHARE && responseCode == RESULT_OK) {
            finish();
        }

    }
