Android通知点击无法启动预期活动

Question

我的通知点击有一个奇怪的问题。以下是我创建通知的方式：

Intent contentIntent;
            if (appointmentId == null) {
                // not an appointment message
                contentIntent = ConversationDetailsActivity.getLaunchIntent(this, conversationId);
            } else {
                // appointment message
                contentIntent = AppointmentDetailsActivity.getLaunchIntent(this, appointmentId);
            }
            PendingIntent contentPendingIntent = PendingIntent.getActivity(this, conversationId.hashCode(), contentIntent, PendingIntent.FLAG_UPDATE_CURRENT);

            NotificationCompat.Builder builder =
                    new NotificationCompat.Builder(this)
                            .setSmallIcon(R.drawable.ic_bubble_24dp)
                            .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher))
                            .setContentTitle(getString(R.string.notification_title))
                            .setContentText(message)
                            .setContentIntent(contentPendingIntent)
                            .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
                            .setVibrate(new long[]{0, 1000, 1000, 1000, 1000})
                            .setLights(Color.WHITE, 3000, 3000);

            manager.notify(conversationId.hashCode(), builder.build());

当我收到'appointmentId'时，通知点击实际启动了AppointmentDetailsActivity。当appointmentId为null时，它应该启动ConversationDetailsActivity，但它会启动MainActivity。我尝试了android:exported="true"解决方案，但它没有用。 两个活动的'getLaunchIntent'方法是相同的，清单声明也是相同的。通知是从服务创建的。我很困惑。请帮我启动正确的活动。谢谢。

AppointmentDetailsActivity的getLaunchIntent（有效的）：

public static Intent getLaunchIntent(final Context context, final String appointmentId) {
    Intent intent = new Intent(context, AppointmentDetailsActivity.class);
    intent.putExtra("appointmentId", appointmentId);
    return intent;
}

ConversationDetailsActivity的getLaunchIntent方法（不起作用的方法）：

public static Intent getLaunchIntent(final Context context, final String conversationId) {
    Intent intent = new Intent(context, ConversationDetailsActivity.class);
    intent.putExtra("conversationId", conversationId);
    return intent;
}

并显示声明：

<activity
    android:name=".ui.conversations.ConversationDetailsActivity"
    android:windowSoftInputMode="stateHidden"
    />
<activity android:name=".ui.appointments.AppointmentDetailsActivity"/>

这个答案here解决了这个问题。
