java - 如何使用 ConnectionService 获取 Call UI Presentation

Question

我正在尝试使用 ConnectionService 从 FCM 通知中呈现 ConnectionService 提供的调用 UI。我缺少什么来完成这个？按照 https://developer.android.com/guide/topics/connectivity/telecom/selfManaged 上的步骤操作我添加了:

<uses-permission android:name="android.permission.MANAGE_OWN_CALLS"/>

和

<service android:name=".SparrowConnectionService"
    android:label="@string/connection_service_label"
    android:permission="android.permission.BIND_TELECOM_CONNECTION_SERVICE">
    <intent-filter>
        <action android:name="android.telecom.ConnectionService" />
    </intent-filter>
</service>

当我收到 FCM 通知时，我会:

TelecomManager telecomManager = (TelecomManager)this.getSystemService(Context.TELECOM_SERVICE);
String packageName = getApplicationContext().getPackageName();
String className = SparrowConnectionService.class.getName();
ComponentName componentName = new ComponentName(packageName, className);
PhoneAccountHandle accountHandle= new PhoneAccountHandle(componentName, "testID");

PhoneAccount account = PhoneAccount.builder(accountHandle, getApplicationContext().getString(R.string.connection_service_label))
        .setCapabilities(PhoneAccount.CAPABILITY_SELF_MANAGED)
        .build();
telecomManager.registerPhoneAccount(account);

Bundle extras = new Bundle();
extras.putParcelable(TelecomManager.EXTRA_PHONE_ACCOUNT_HANDLE, accountHandle);
extras.putInt(TelecomManager.EXTRA_START_CALL_WITH_VIDEO_STATE, VideoProfile.STATE_BIDIRECTIONAL);
telecomManager.addNewIncomingCall(accountHandle, extras);

这成功触发了我的 ConnectService 的 onCreateIncomingConnection 方法(CallConnection extends Connection)

@Override
public Connection onCreateIncomingConnection(PhoneAccountHandle connectionManagerPhoneAccount, ConnectionRequest request) {
    Log.d(TAG, "onCreateIncomingConnection");
    CallConnection connection = new CallConnection(getApplicationContext());
    connection.setConnectionProperties(Connection.PROPERTY_SELF_MANAGED);
    connection.setCallerDisplayName("TestID", TelecomManager.PRESENTATION_ALLOWED);

    Bundle extras = new Bundle();
    extras.putBoolean(Connection.EXTRA_ANSWERING_DROPS_FG_CALL, true);
    extras.putString(Connection.EXTRA_CALL_SUBJECT, "Test call subject text");
    connection.putExtras(extras);
    return connection;
}

这会调用我的 CallConnection 的 onShowIncomingCallUi 方法，但不显示任何 UI。如何显示 UI？

Answer 1

您需要在 onShowIncomingCallUi 方法中显示您的来电 UI。 self 管理的 ConnectionService API 旨在用于调用希望提供自己的完整调用 UI，但仍希望与 Android 中的移动调用共存的应用程序。
