有没有什么办法可以动态地生成上行链路双音多频(即接收器听到它)?
当我看着Android源$ C $ C,我看到一个调用的函数 startDTMF()这正是我需要的,但我找不到任何API这使我能够访问该功能......
然后我想用ToneGenerator,并试图以声音的麦克风流注入,而我又无法找到一种方法来实现这一目标?
任何帮助是AP preciated。

这可以提供帮助。 ,产生一个4秒的延迟,所以您可以使用该在的地方,有时... 但我们仍然需要得到一些东西从SDK让希望Android的家伙找到了!
Is there any way I can dynamically generate uplink DTMF tone (ie the receiver hears it)?
When I looked at the android source code I saw a function called startDTMF() which is exactly what I need, but I couldn't find any API that allows me to access that function...
I then thought of using ToneGenerator and tried to inject the sound to the mic stream, and again I couldn't find a way to achieve this...
Any help is appreciated.
