Once the PendingIntent has been launched the user will be\npresented with a UI, listing out all (SIM-based) phone numbers. The user can\nthen choose to select a phone number they would like to use or cancel the flow.\nThe selected phone number will then be made available to the developer to\nretrieve from the [`Intent`](/reference/android/content/Intent).\n**Figure 1.** Phone Number Hint UI and Settings\n\nTo prepare your app, complete the steps in the following sections.\n\nConfigure your app\n------------------\n\nAdd the [Google Play services](https://developers.google.com/android)\ndependency for the Phone Number Hint API to your\n[module's Gradle build file](/studio/build#module-level),\nwhich is commonly `app/build.gradle`: \n\n apply plugin: 'com.android.application'\n\n ...\n\n dependencies {\n implementation 'com.google.android.gms:play-services-auth:21.4.0'\n }\n\n### Create a GetPhoneNumbeHintIntentRequest object\n\nStart by creating a [`GetPhoneNumberHintIntentRequest`](https://developers.google.com/android/reference/com/google/android/gms/auth/api/identity/GetPhoneNumberHintIntentRequest) object using the\nprovided [`GetPhoneNumberHintIntentRequest.Builder()`](https://developers.google.com/android/reference/com/google/android/gms/auth/api/identity/GetPhoneNumberHintIntentRequest.Builder)\nmethod. This request object can then be used to get an `Intent` to start the\nPhone Number Hint flow. \n\n### Kotlin\n\n```kotlin\nval request: GetPhoneNumberHintIntentRequest = GetPhoneNumberHintIntentRequest.builder().build()\n```\n\n### Java\n\n```java\nGetPhoneNumberHintIntentRequest request = GetPhoneNumberHintIntentRequest.builder().build();\n```\n\n### Requesting Phone Number Hint\n\nCall [`SignInClient.getPhoneNumberHintIntent()`](https://developers.google.com/android/reference/com/google/android/gms/auth/api/identity/SignInClient#getPhoneNumberHintIntent(com.google.android.gms.auth.api.identity.GetPhoneNumberHintIntentRequest)),\npassing in the previous `GetPhoneNumberHintIntentRequest` object,\nto retrieve the `PendingIntent` to initiate the Phone Number Hint flow. \n\n### Kotlin\n\n```kotlin\nval phoneNumberHintIntentResultLauncher = ...\n\nIdentity.getSignInClient(activity)\n.getPhoneNumberHintIntent(request)\n.addOnSuccessListener { result: PendingIntent -\u003e\n try {\n phoneNumberHintIntentResultLauncher.launch(\n IntentSenderRequest.Builder(result).build()\n )\n } catch (e: Exception) {\n Log.e(TAG, \"Launching the PendingIntent failed\")\n }\n}\n.addOnFailureListener {\n Log.e(TAG, \"Phone Number Hint failed\")\n}\n```\n\n### Java\n\n```java\nActivityResultLauncher phoneNumberHintIntentResultLauncher = ...\n\nIdentity.getSignInClient(activity)\n .getPhoneNumberHintIntent(request)\n .addOnSuccessListener( result -\u003e {\n try {\n phoneNumberHintIntentResultLauncher.launch(result.getIntentSender());\n } catch(Exception e) {\n Log.e(TAG, \"Launching the PendingIntent failed\", e);\n }\n })\n .addOnFailureListener(e -\u003e {\n Log.e(TAG, \"Phone Number Hint failed\", e);\n });\n```\n\n### Retrieving the phone number\n\nPass in the `Intent` to [`SignInClient.getPhoneNumberFromIntent`](https://developers.google.com/android/reference/com/google/android/gms/auth/api/identity/SignInClient#getPhoneNumberFromIntent(android.content.Intent))\nto retrieve the phone number. \n\n### Kotlin\n\n```kotlin\nval phoneNumberHintIntentResultLauncher =\nregisterForActivityResult(ActivityResultContracts.StartIntentSenderForResult()) { result -\u003e\n try {\n val phoneNumber = Identity.getSignInClient(activity).getPhoneNumberFromIntent(result.data)\n } catch(e: Exception) {\n Log.e(TAG, \"Phone Number Hint failed\")\n }\n }\n```\n\n### Java\n\n```java\nActivityResultLauncher phoneNumberHintIntentResultLauncher =\n registerForActivityResult(\n new ActivityResultContracts.StartActivityForResult(),\n new ActivityResultCallback() {\n @Override\n public void onActivityResult(ActivityResult result) {\n try {\n String phoneNumber = Identity.getSignInClient(activity).getPhoneNumberFromIntent(result.getData());\n } catch {\n Log.e(TAG, \"Phone Number Hint failed\", e);\n }\n }\n });\n```"]]
