我找到了解决方案。您需要为此创建一个前台服务。
这也将帮助您在锁定屏幕上显示响铃拨号器。在此代码中，我添加了铃声和振动。

我们需要在应用程序选项卡内的清单中设置这两个
manifest
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.USE_FULL_SCREEN_INTENT"/>
<uses-permission android:name="android.permission.VIBRATE" />
<!-- Incoming call -->
<service android:name=".CallNotificationService"/>
<receiver
android:name=".CallNotificationActionReceiver"
android:enabled="true">
<intent-filter android:priority="999">
<action android:name="ConstantApp.CALL_RECEIVE_ACTION" />
<action android:name="ConstantApp.CALL_CANCEL_ACTION"/>
</intent-filter>
</receiver>
要启动该服务，您需要从 firebase 通知服务中调用它。
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
Intent serviceIntent = new Intent(getApplicationContext(), CallNotificationService.class);
Bundle mBundle = new Bundle();
mBundle.putString("inititator", name);
mBundle.putString("call_type",callType);
serviceIntent.putExtras(mBundle);
ContextCompat.startForegroundService(getApplicationContext(), serviceIntent);
}
停止通知
getApplicationContext().stopService(new Intent(AppController.getInstance().getContext(), HeadsUpNotificationService.class));
Intent istop = new Intent(Intent.ACTION_CLOSE_SYSTEM_DIALOGS);
getApplicationContext().sendBroadcast(istop);
