To ensure the continued security and usability of your app, <a href="https://developer.android.com/training/sign-in/credential-manager/">migrate to Credential Manager</a> today. Credential Manager supports passkey, password, and federated identity authentication (such as Sign-in with Google), stronger security, and a more consistent user experience. For Wear developers: Credential Manager will be supported in Wear OS 5.1 and later on selected watches. Developers actively supporting Wear OS 3, 4 and 5.0 devices with Sign in with Google should continue using Google Sign-in for Android for your Wear applications. Sign in with Google support will be available on Credential Manager APIs for these versions of WearOS at a later date. </aside> <aside class="warning"><strong>Warning:</strong><span> This page is out of date, refer to <a href="/identity/sign-in/android/authorize-access">Authorize Access to User Data</a> for the latest best practice.</span></aside> <p>For the best user experience, you should request as few scopes as possible when initially signing in users. If your app's core functionality isn't tied to a Google service, the <code translate="no" dir="ltr">GoogleSignInOptions.DEFAULT_SIGN_IN</code> configuration is often all you need at sign-in.</p> <p>If your app has features that can make use of Google API data, but are not required as part of your app's core functionality, you should design your app to be able to gracefully handle cases when API data isn't accessible. For example, you might hide a list of recently saved files when the user hasn't granted Drive access.</p> <p>You should request additional scopes that you need to access Google APIs only when the user performs an action that requires access to a particular API. For example, you might request permission to access the user's Drive only when the user taps a "Save to Drive" button for the first time.</p> <p>By using this technique, you can avoid overwhelming new users, or confusing users as to why they are being asked for certain permissions.</p> <h2 id="requesting_permissions_required_by_user_actions" data-text="Requesting permissions required by user actions" tabindex="-1">Requesting permissions required by user actions</h2> <p>Whenever a user performs an action that requires a scope that isn't requested at sign-in, call <code translate="no" dir="ltr">GoogleSignIn.hasPermissions</code> to check if the user has already granted the required permissions. If not, call <code translate="no" dir="ltr">GoogleSignIn.requestPermissions</code> to launch an activity that requests the additional required scopes from the user.</p> <p>For example, if a user performs an action that requires access to their Drive app storage, do the following:</p> <div></div><devsite-code><pre class="devsite-click-to-copy" translate="no" dir="ltr" is-upgraded syntax="scdoc"><code translate="no" dir="ltr">if (!GoogleSignIn.hasPermissions( GoogleSignIn.getLastSignedInAccount(getActivity()), Drive.SCOPE_APPFOLDER)) { GoogleSignIn.requestPermissions( MyExampleActivity.this, RC_REQUEST_PERMISSION_SUCCESS_CONTINUE_FILE_CREATION, GoogleSignIn.getLastSignedInAccount(getActivity()), Drive.SCOPE_APPFOLDER); } else { saveToDriveAppFolder(); } </code></pre></devsite-code> <p>In your activity's <code translate="no" dir="ltr">onActivityResult</code> callback, you can check if the required permissions were successfully acquired, and if so, carry out the user action.</p> <div></div><devsite-code><pre class="devsite-click-to-copy" translate="no" dir="ltr" is-upgraded syntax="Transact-SQL"><code translate="no" dir="ltr"><span class="devsite-syntax-nv">@Override</span> <span class="devsite-syntax-k">public</span><span class="devsite-syntax-w"> </span><span class="devsite-syntax-n">void</span><span class="devsite-syntax-w"> </span><span class="devsite-syntax-n">onActivityResult</span><span class="devsite-syntax-p">(</span><span class="devsite-syntax-nc">int</span><span class="devsite-syntax-w"> </span><span class="devsite-syntax-n">requestCode</span><span class="devsite-syntax-p">,</span><span class="devsite-syntax-w"> </span><span class="devsite-syntax-nc">int</span><span class="devsite-syntax-w"> </span><span class="devsite-syntax-n">resultCode</span><span class="devsite-syntax-p">,</span><span class="devsite-syntax-w"> </span><span class="devsite-syntax-n">Intent</span><span class="devsite-syntax-w"> </span><span class="devsite-syntax-k">data</span><span class="devsite-syntax-p">)</span><span class="devsite-syntax-w"> </span><span class="devsite-syntax-err">{</span> <span class="devsite-syntax-w"> </span><span class="devsite-syntax-n">super</span><span class="devsite-syntax-p">.</span><span class="devsite-syntax-n">onActivityResult</span><span class="devsite-syntax-p">(</span><span class="devsite-syntax-n">requestCode</span><span class="devsite-syntax-p">,</span><span class="devsite-syntax-w"> </span><span class="devsite-syntax-n">resultCode</span><span class="devsite-syntax-p">,</span><span class="devsite-syntax-w"> </span><span class="devsite-syntax-k">data</span><span class="devsite-syntax-p">);</span> <span class="devsite-syntax-w"> </span><span class="devsite-syntax-k">if</span><span class="devsite-syntax-w"> </span><span class="devsite-syntax-p">(</span><span class="devsite-syntax-n">resultCode</span><span class="devsite-syntax-w"> </span><span class="devsite-syntax-o">==</span><span class="devsite-syntax-w"> </span><span class="devsite-syntax-n">Activity</span><span class="devsite-syntax-p">.</span><span class="devsite-syntax-n">RESULT_OK</span><span class="devsite-syntax-p">)</span><span class="devsite-syntax-w"> </span><span class="devsite-syntax-err">{</span> <span class="devsite-syntax-w"> </span><span class="devsite-syntax-k">if</span><span class="devsite-syntax-w"> </span><span class="devsite-syntax-p">(</span><span class="devsite-syntax-n">RC_REQUEST_PERMISSION_SUCCESS_CONTINUE_FILE_CREATION</span><span class="devsite-syntax-w"> </span><span class="devsite-syntax-o">==</span><span class="devsite-syntax-w"> </span><span class="devsite-syntax-n">requestCode</span><span class="devsite-syntax-p">)</span><span class="devsite-syntax-w"> </span><span class="devsite-syntax-err">{</span> <span class="devsite-syntax-w"> </span><span class="devsite-syntax-n">saveToDriveAppFolder</span><span class="devsite-syntax-p">();</span> <span class="devsite-syntax-w"> </span><span class="devsite-syntax-err">}</span> <span class="devsite-syntax-w"> </span><span class="devsite-syntax-err">}</span> <span class="devsite-syntax-err">}</span> </code></pre></devsite-code> <p>You can also pass a <code translate="no" dir="ltr">GoogleSignInOptionsExtension</code> to <code translate="no" dir="ltr">hasPermissions</code> and <code translate="no" dir="ltr">requestPermissions</code> to check for and acquire a set of permissions more conveniently.</p> </div> <devsite-recommendations display="in-page" hidden yield> </devsite-recommendations> <devsite-thumb-rating position="footer"> </devsite-thumb-rating> <devsite-feedback position="footer" project-name="Authentication" product-id="5186570" bucket="Identity guides" context="External devsite feedback" version="t-devsite-webserver-20241114-r00-rc02.464922260396498922" data-label="Send Feedback Button" track-type="feedback" track-name="sendFeedbackLink" track-metadata-position="footer" class="nocontent" project-icon="https://www.gstatic.com/devrel-devsite/prod/v870e399c64f7c43c99a3043db4b3a74327bb93d0914e84a0c3dba90bbfd67625/developers/images/touchicon-180-new.png" > <button> Send feedback </button> </devsite-feedback> <devsite-recommendations id="recommendations-link" yield></devsite-recommendations> <div class="devsite-floating-action-buttons"> </div> </article> <devsite-content-footer class="nocontent"> <p>Except as otherwise noted, the content of this page is licensed under the <a href="https://creativecommons.org/licenses/by/4.0/">Creative Commons Attribution 4.0 License</a>, and code samples are licensed under the <a href="https://www.apache.org/licenses/LICENSE-2.0">Apache 2.0 License</a>.
