后台音频在正在进行的呼叫 - 可能吗？ [英] Background Audio for a Call in Progress - Possible?

问题描述

我写这是应该的播放一个音频文件时，通话中从一个具体的数字来。我试过很多方法..但在静脉都去<一个Android应用/ p>

1. 单独的线程


2. 在电话服务监听


3. 开始并行
服务

任何一个可以请帮我如何对此进行呢？

更新：

我能够发挥随叫随到收到一个MP3文件，我能够发挥它的扬声器负载..但怎么过响我玩的是主叫方是不是能听它....反正我有可以推动扬声器流调用流

解决方案

从API文档的此处

  

请注意：您可以将音频数据回放只有到标准输出
  设备。目前，这是在移动设备的扬声器或蓝牙
  耳机。在交谈过程中的音频无法播放声音文件
  一个电话。

所以从这个和其他很多这样的答案，我们可以得出结论，在通话过程中过程中，我们不能播放音频。

不过从手机中的个人经历很长一段时间以前，我得到了一个结果，其中audiotrack被打，而有一个呼叫建立，无论是声音被同时听到。所以我觉得这要看手机是否允许它那么你就可以玩了。

您可以尝试另一件事实验。发挥使用不同的途径（免提或蓝牙）音频。

另一个选择是建立自己的定制的Andr​​oid版本。

I am writing a android app which is supposed to play back a audio file when a call is in progress coming from a specific number .. I tried many approaches.. but all went in vein

1. Separate Thread
2. Listener on Telephone service
3. starting a service in parallel

can any one please help me how to proceed regarding this ?

Update :

I am able to play a mp3 file on call recieve and i am able to play it load on speaker.. but how ever loud i play the calling party is not able to listen to it.... is there anyway i can push the speaker stream to call stream

解决方案

From the api doc here

Note: You can play back the audio data only to the standard output device. Currently, that is the mobile device speaker or a Bluetooth headset. You cannot play sound files in the conversation audio during a call.

So from this and lots of other so answers we can conclude that we can not play an audio during a call process.

But a long time ago from a personal experience with a handset I got a result where the audiotrack was playing while there was a call established and both the voices were heard at the same time. So I think this depends on handsets if it allows it then you can play.

You can try another thing experimentally. play the audio using a different route ( speakerphone or bluetooth).

Another option is to build your custom android build
