This project will simplify the user Google authentication you can Directly use this project Code.
I made this project with our Future and reliable Platform Tool Android Studio for Android developer.
First of all check this project in this Project i added the one Package name Google Authenticator use that package with your project.
Step 1: copy google authenticator into your project and it will make the some errors.
Step 2: You need to import the
compile 'com.google.android.gms:play-services:6.5.87'library into your project.It will resolve your problems
Step 3: And one more important steps in this project is you need to create a GOOGLE API CREDENTIALS in your google console developers site https://console.developers.google.com/
from the above site you can create the api credentials for your application.
Add some more lines into your AndroidMainfest file
<application>
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
</application>And don't forgot to add the internet access permissions into your mainfest file
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>Step 4: Then Initialize the global variable of our Google Authenticator in your Activity file like below.
private GoogleAuthenticator mGoogleAuthenticator;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_authentication);
/**
* Necessary initialize to get authentication
**/
mGoogleAuthenticator = new GoogleAuthenticator(this);
mGoogleAuthenticator.setGoogleAuthListener(this);
}Step 5: You need implement the GoogleAuthListener interface
public class AuthenticationActivity extends ActionBarActivity implements GoogleAuthListener {
@Override
public void setAuthenticationSuccess(final User user) {
//get your success user details here
}
@Override
public void setAuthenticationFailed(final String errorMessage) {
//get your failure message here
}
}Step 6: The you need to write a few coding on your activityresult method
Write these lines into your Activity
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == Constants.REQUEST_CODE_PICK_ACCOUNT) {
if (resultCode == RESULT_OK) {
String email = data.getStringExtra(AccountManager.KEY_ACCOUNT_NAME);
//Authenticator variable name
mGoogleAuthenticator.getUsername(email);
} else if (resultCode == RESULT_CANCELED) {
mGoogleAuthenticator.handleAuthorizeResult(resultCode, data);
}
} else if ((requestCode == Constants.REQUEST_CODE_RECOVER_FROM_AUTH_ERROR ||
requestCode == Constants.REQUEST_CODE_RECOVER_FROM_PLAY_SERVICES_ERROR)
&& resultCode == RESULT_OK) {
mGoogleAuthenticator.handleAuthorizeResult(resultCode, data);
return;
}
super.onActivityResult(requestCode, resultCode, data);
}Step 7: Final step if you did the above steps properly then you can execute the authenticator
if (mGoogleAuthenticator != null) {
mGoogleAuthenticator.execute();
