Auf Geräten mit Android 10 oder höher werden Anruf-Intents anders verwaltet als
mit Android 9 oder niedriger. Unter Android 10 und höher
ACTION_NEW_OUTGOING_CALL
Broadcast wurde eingestellt und durch den
CallRedirectionService
der API erstellen. Der CallRedirectionService
stellt Schnittstellen zur Verfügung, die Sie für folgende Aktionen verwenden können:
Ausgehende Anrufe über die Android-Plattform ändern Beispiel: Drittanbieter
Apps können Anrufe abbrechen und über VoIP umleiten.
Kotlin
class RedirectionService : CallRedirectionService() {
override fun onPlaceCall(
handle: Uri,
initialPhoneAccount: PhoneAccountHandle,
allowInteractiveResponse: Boolean
) {
// Determine if the call should proceed, be redirected, or cancelled.
val callShouldProceed = true
val callShouldRedirect = false
when {
callShouldProceed -> {
placeCallUnmodified()
}
callShouldRedirect -> {
// Update the URI to point to a different phone number or modify the
// PhoneAccountHandle and redirect.
redirectCall(handle, initialPhoneAccount, true)
}
else -> {
cancelCall()
}
}
}
}
Java

Sie müssen diesen Dienst im Manifest registrieren, damit das System ihn starten kann
korrekt sind.
<service
android:name=".RedirectionService"
android:permission="android.permission.BIND_CALL_REDIRECTION_SERVICE">
<intent-filter>
<action android:name="android.telecom.CallRedirectionService"/>
</intent-filter>
</service>
Damit Sie einen Weiterleitungsdienst verwenden können, muss Ihre App die Rolle „Anrufweiterleitung“ anfordern
aus dem RoleManager
. Sie werden gefragt,
ob Ihre App Anrufweiterleitungen verarbeiten darf. Wenn Ihre App
diese Rolle nicht gewährt wird, wird Ihr Weiterleitungsdienst nicht verwendet.
Sie sollten prüfen, ob Ihre App diese Rolle hat, wenn der Nutzer Ihre App startet, damit
können Sie sie bei Bedarf anfordern. Sie starten einen von RoleManager
erstellten Intent,
überschreiben Sie die
onActivityResult()
die Auswahl der Nutzenden.

On Android 10 and higher, the\n[`ACTION_NEW_OUTGOING_CALL`](/reference/android/content/Intent#ACTION_NEW_OUTGOING_CALL)\nbroadcast is deprecated and replaced with the\n[`CallRedirectionService`](/reference/android/telecom/CallRedirectionService)\nAPI. The `CallRedirectionService` provides interfaces for you to use to\nmodify outgoing calls made by the Android platform. For example, third-party\napps might cancel calls and reroute them over VoIP. \n\n### Kotlin\n\n```kotlin\nclass RedirectionService : CallRedirectionService() {\n override fun onPlaceCall(\n handle: Uri,\n initialPhoneAccount: PhoneAccountHandle,\n allowInteractiveResponse: Boolean\n ) {\n // Determine if the call should proceed, be redirected, or cancelled.\n val callShouldProceed = true\n val callShouldRedirect = false\n when {\n callShouldProceed -\u003e {\n placeCallUnmodified()\n }\n callShouldRedirect -\u003e {\n // Update the URI to point to a different phone number or modify the\n // PhoneAccountHandle and redirect.\n redirectCall(handle, initialPhoneAccount, true)\n }\n else -\u003e {\n cancelCall()\n }\n }\n }\n}\n```\n\n### Java\n\n```java\nclass RedirectionService extends CallRedirectionService {\n @Override\n public void onPlaceCall(\n @NonNull Uri handle,\n @NonNull PhoneAccountHandle initialPhoneAccount,\n boolean allowInteractiveResponse\n ) {\n // Determine if the call should proceed, be redirected, or cancelled.\n // Your app should implement this logic to determine the redirection.\n boolean callShouldProceed = true;\n boolean callShouldRedirect = false;\n if (callShouldProceed) {\n placeCallUnmodified();\n } else if (callShouldRedirect) {\n // Update the URI to point to a different phone number or modify the\n // PhoneAccountHandle and redirect.\n redirectCall(handle, initialPhoneAccount, true);\n } else {\n cancelCall();\n }\n }\n}\n```\n\nYou must register this service in the manifest so the system can start it\ncorrectly. \n\n \u003cservice\n android:name=\".RedirectionService\"\n android:permission=\"android.permission.BIND_CALL_REDIRECTION_SERVICE\"\u003e\n \u003cintent-filter\u003e\n \u003caction android:name=\"android.telecom.CallRedirectionService\"/\u003e\n \u003c/intent-filter\u003e\n \u003c/service\u003e\n\nTo use a redirection service, your app must request the call redirection role\nfrom the [`RoleManager`](/reference/android/app/role/RoleManager). This will ask\nthe user if they want to allow your app to handle call redirects. If your app\nisn't granted this role, your redirection service isn't used.\n\nYou should check if your app has this role when the user launches your app so\nyou can request it as needed. You launch an intent created by the `RoleManager`,\nso ensure you override the\n[`onActivityResult()`](/reference/android/app/Activity#onActivityResult(int,%20int,%20android.content.Intent))\nfunction to handle the user's selection. \n\n### Kotlin\n\n```kotlin\nclass MainActivity : AppCompatActivity() {\n override fun onCreate(savedInstanceState: Bundle?) {\n super.onCreate(savedInstanceState)\n setContentView(R.layout.activity_main)\n\n // Tell the system that you want your app to handle call redirects.
