如何在Android中停止FCM通知？

FirebaseInstanceId.getInstance().getInstanceId()
    .addOnCompleteListener(new OnCompleteListener<InstanceIdResult>() {
        @Override
        public void onComplete(@NonNull Task<InstanceIdResult> task) {
            if (!task.isSuccessful()) {
                Log.w(TAG, "getInstanceId failed", task.getException());
                return;
            }

            // 获取当前设备的FCM实例ID
            String token = task.getResult().getToken();

            // 删除FCM实例ID
            FirebaseInstanceId.getInstance().deleteInstanceId()
                .addOnCompleteListener(new OnCompleteListener<Void>() {
                    @Override
                    public void onComplete(@NonNull Task<Void> task) {
                        if (task.isSuccessful()) {
                            Log.d(TAG, "FCM实例ID删除成功");
                        } else {
                            Log.w(TAG, "FCM实例ID删除失败", task.getException());
                        }
                    }
                });
        }
    });
