android - Quickblox - Android 应用程序的 SDK 在应用程序处于后台时不接听电话

Question

我正在使用适用于 Android 的 Quickblox-SDK 开发视频通话应用程序。如果应用程序打开，应用程序运行良好且完美但如果应用程序在后台，我将无法接听电话。我使用这个 link 创建了应用程序请帮忙。我尝试了以下操作:

1) 当通知到达时打开 CallActivity，使用 GCM 进行通知，但作为接收通知的通话时间，这个东西也不起作用。

谢谢。

Answer 1

创建一个将在后台运行甚至 Activity 销毁的粘性服务，该服务负责 QBsession 和所有其他操作，因此它将在后台检测调用。我成功地实现了这一点，并且我通过它成功地在后台接听电话。
