# The Google plus Social API Integration
## Google plus Social API Integration (G+ Login in android)
Before [Social login](https://www.mindstick.com/articles/12423/social-login-magento-2-one-click-to-register-social) in android, first of all, you have to **enable [your app](https://answers.mindstick.com/qa/33368/how-will-you-design-a-listview-which-downloads-a-lot-of-images-and-displays-in-it-without-getting-your-app-hanged-whats-the-best-possible-way).** \
**Step 1:** To enable your app to get Google plus [user profile](https://answers.mindstick.com/qa/93400/how-can-i-achieve-a-verified-user-profile-at-mindstick), open following **https://console.developers.google.com/cloud-resource-manager** after that click on **Create** a **New Project.**
**Step 2:** install/update Google Play [Services](https://answers.mindstick.com/qa/93329/what-is-a-pest-control-services)-
In [Android Studio](https://answers.mindstick.com/qa/51181/how-to-create-a-log-error-file-in-android-studio-and-also-perform-read-write-operation-in-a-file), select **Tools > Android > SDK Manager>SDK Tools** and install or update the play services.
**Step 3:** Generating **Google-Service.json** File.
Now all the android [projects](https://www.mindstick.com/articles/105927/how-to-excel-at-managing-multiple-projects) which use **Google APIs require a google-services.[json file](https://www.mindstick.com/forum/158972/how-to-read-appsettings-values-from-a-json-file-in-asp-dot-net-core)** to be placed in the project’s app folder. Follow the below steps to get your google-services.json file.
--> First of all, generate the SHA-1 fingerprint. Java key-tool can be used to generate the SHA-1 fingerprint. Open your terminal(cmd) and execute the following command to generate the SHA-1 fingerprint. If it asks for a password, type android, and press enter.
## For windows follow the following command in java bin folder-
keytool -list -v -keystore "%USERPROFILE%\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android
## In My Project
First we open cmd --->cd C:\Program Files\Java\jdk-9.0.4\bin--->press enter --->after that write below command to generate SHA-1 fingerprints.
**keytool -list -v -keystore "C:\Users\msclient009\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android**
\
**Step 4:** Go back following link **https://developers.google.com/identity/sign-in/android/start-integrating** click on **Configure A Project.**
 **\**
After that **Select or Create Project** click on next select your **platform Android** and **fill the required field** and click on create.
\
[Download](https://www.mindstick.com/blog/114673/download-hungry-shark-evolution-mod-apk-unlimited-money) Your **Credentials (Google-service.json)** file. After that **copy the Google-service.json file and paste it into [your project](https://answers.mindstick.com/qa/93843/is-it-necessary-to-add-bootstrap-js-and-bootstrap-css-both-in-your-project).**
\
## \
## Step 5: Create Your Project
In your project's top-level **build.gradle** file adds the below code.
```
allprojects { repositories { google() }}
```
Then, in your app-level **build.gradle** file, declare Google Play services as a [dependency](https://www.mindstick.com/news/2358/apple-will-use-us-made-semiconductors-in-its-products-to-lessen-its-dependency-on-asia):
```
apply plugin: 'com.android.application' ... dependencies { compile 'com.google.android.gms:play-services-auth:15.0.1' }
```
**Step 6:** Add the Google Sign in button in Your Project (**main_activity.java**).
```
```
**Add the below code in your MainActivity.java file.**
```
mSignInOptions = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN).requestEmail().build();mGoogleApiClient = new GoogleApiClient.Builder(this) .enableAutoManage(this, this).addApi(Auth.GOOGLE_SIGN_IN_API, mSignInOptions).build();Button signInButton = findViewById(R.id.sign_in_button);signInButton.setOnClickListener(this);@Overridepublic void onClick(View v) { switch (v.getId()) { case R.id.sign_in_button: signIn(); break; // ... }}public void googleSignIn() { Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient); startActivityForResult(signInIntent, REQ_CODE_GOOGLE_SIGN_IN);}@Overridepublic void startActivityForResult(Intent intent, int requestCode) { intent.putExtra("requestCode", requestCode); super.startActivityForResult(intent, requestCode);}@Overridepublic void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); Log.v("Request Code", String.valueOf(requestCode)); if (requestCode == REQ_CODE_GOOGLE_SIGN_IN) { Task task = GoogleSignIn.getSignedInAccountFromIntent(data); handleSignInResult(task); }}private void handleSignInResult(Task completedTask) { try { GoogleSignInAccount account = completedTask.getResult(ApiException.class); String name = account.getDisplayName(); String firstName = ""; String lastName = ""; if (name != null) { int end = name.lastIndexOf(' '); if (end >= 0) { firstName = name.substring(0, end); lastName = name.substring(end + 1, name.length()); } } Log.v(" Google Profile Name : ", firstName + lastName + account.getEmail() + account.getId()); Toast.makeText(getApplicationContext(),"Google+ Login Successful",Toast.LENGTH_SHORT).show(); loginApi("Google", account.getId(), firstName, lastName, account.getEmail()); } catch (ApiException e) { Log.e("Google Plus Login : ", e.getMessage(), e); Log.w("Value", "signInResult:failed code=" + e.getStatusCode()); Toast.makeText(this,"Login failure : "+ e.getStatusCode(), Toast.LENGTH_LONG).show(); } }public void loginApi(String provider, String providerId, String firstName, String lastName, String emailId) { LoginAsyncTask asyncTask = new LoginAsyncTask(getApplicationContext(), provider, providerId, firstName, lastName, emailId); asyncTask.delegate = this; asyncTask.execute();}@Overridepublic void ifSuccess(boolean check) { if (check) { loginProgress.setVisibility(View.GONE); try { String className = getIntent().getStringExtra("ClassName"); if(className.equals("LoginRegisterFragment") || className.equals("UserActivity") || className.equals("RegisterActivity")) { Intent intent = new Intent(UserLoginActivity.this, UserActivity.class); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK); intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION); startActivity(intent); finish(); } } catch (Exception e) { e.printStackTrace(); } previousPage(); finish(); } else { loginProgress.setVisibility(View.GONE); loginSubmit.setClickable(true); Toast.makeText(this, "email or password is incorrect", Toast.LENGTH_SHORT).show(); }}
```
