当活动要求完成通知pendingIntent contentIntent失败（） [英] Notification pendingIntent contentIntent fails when activity calls finish()

问题描述

我有一个前台服务通知，当点击应该开始一个活动。它调用完成（）之前，此活动是非常短暂的。

I have a foreground service notification that when clicked should start an activity. This activity is very short lived before it calls finish().

第一次通知，点击它的工作原理，第二次，然后我得到的错误：

The first time the notification is clicked it works, the second time and thereafter I get the error:

    Sending contentIntent failed: android.app.PendingIntent$CanceledException

在我的code创建前台服务通知的时候，我已经改变了randomActivity.class到不调用完成另一个活动类和它完美的作品在每一次点击。发件人：

In my code when creating the foreground service notification, I've changed the randomActivity.class to another Activity class that does not call finish and it works perfectly on every click. From:

    Intent notificationIntent = new Intent(this, RandomActivity.class);

到

    Intent notificationIntent = new Intent(this, HomeActivity.class);

做工精细...

Works fine...

我已经使用了标准通知code从Android开发者网站，以及使用通知建设者测试。我得到了相同的结果而不管。它的工作原理完全除非活动调用完成（）;

I've used the standard notification code from the Android Developers website, as well as testing it using Notification builder. I get the same result regardless. It works perfectly unless the Activity calls finish();

这是预期的行为，错误，还是我失去了一些东西？

您的帮助，我感谢你在有希望的解决方案！

I thank you in advance for you help and hopefully a solution!

注：通知code我用的是完全标准的，所以我没有把它贴。 RandomActivity称光洁度（）;在的onCreate，所以没有什么不寻常的看到有两种。

Note: The notification code I use is completely standard, so I haven't posted it. RandomActivity calls finish(); in onCreate, so there's nothing unusual to see there either.

推荐答案

乱投医后，我可能会，我终于找到了解决办法。发帖万一有人过这个问题绊倒了。

After trying everything I possibly could, I eventually found a solution. Posting in case anyone stumbles across this issue too.

我不得不匹配INT请求code的通知ID。为什么？完全不知道......我只能假设这$成为空或重新使用p $ pvents的意图数据？

I had to match the int requestCode to the notification id. Why? Absolutely no idea... I can only assume it prevents the intent data from becoming null or reusing it?

    private static int ONGOING_NOTIFICATION_ID = 76;

    PendingIntent contentIntent = PendingIntent.getActivity(this,
    ONGOING_NOTIFICATION_ID, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);

同为通知ID为startForeground：

The same as the notification id to startForeground:

    this.startForeground(ONGOING_NOTIFICATION_ID, not);

希望这可以帮助别人。

Hope this helps someone.
